X-Planes: Synthesis and What the Designation Became
Filed under: aerospace, history, engineering
This is the seventy-second and last article in the X-Planes series, following the X-1, the X-2, the X-3, the X-4, the X-5, the X-6, the X-7, the X-8, the X-9, the X-10, the X-11, the X-12, the X-13, the X-14, the X-15, the X-16, the X-17, the X-18, the X-19, the X-20, the X-21, the X-22, the X-23, the X-24, the X-25, the X-26, the X-27, the X-28, the X-29, the X-30, the X-31, the X-32, the X-33, the X-34, the X-35, the X-36, the X-37, the X-38, the X-39, the X-40, the X-41, the X-42, the X-43, the X-44, the X-45, the X-46, the X-47, the X-48, the X-49, the X-50, the X-51, the X-52, the X-53, the X-54, the X-55, the X-56, the X-57, the X-58, the X-59, the X-60, the X-61, the X-62, the X-63, the X-64, the X-65, the X-66, the X-67, the X-68, the X-69 through X-75, and the X-76.
An X number began as a count of instruments and still mostly is one, and what changed around it can now be measured. The first article of this series proposed that a research aircraft is an instrument built to measure one quantity that ground facilities cannot settle, and that the designation sequence is itself an object with measurable properties [X-Planes framing]. Seventy articles later the series holds a record for every design number from 1 to 76, and this article treats those records as data. Each earlier article is read for a fixed set of facts, and each stated fact is taken from the article that states it, with its quotation. What follows counts across those records instead of recalling them.
Five results carry the argument. The first is that who flew aboard changed. Of the vehicles whose design crew the articles record, 20 of 28 that entered the series before 1990 carried a pilot, and 8 of 30 after it, a difference Fisher’s exact test puts at a two-sided probability of 0.00138 under the hypothesis of no change. The second is that the numbers almost always kept their order where the record can test it. Across the 23 research design numbers whose first allocation the register of allocations dates as the A model, which covers allocations from 1997 onward, Kendall’s rank correlation between number and date is 0.984, with exactly one pair out of order, the X-49 allocated after the X-50. The third is that every skip in the register’s research series has a recorded cause, and the first of them was numerology in 2002, when the number 50 was requested for a helicopter-aeroplane hybrid described as a fifty-fifty marriage, by the Defense Advanced Research Projects Agency, DARPA, in the register compiler’s account and by Boeing in its own [X-49] [X-69 through X-75]. The fourth is that allocations arrive in clusters. The index of dispersion of entry years by decade is 2.90 to 3.60, depending on how a number’s entry year is dated, against 1 for a process without memory. The fifth is that the numbers have recorded outcomes as well as authorised attempts since the first decade. Of the 22 flown vehicles whose articles date both events, 6 were designated after their first flight, and the earliest of them are the X-8 and the X-9, both of 1951, not the X-53 of 2006.
The purpose of the aeroplanes moved less clearly than their crews did. The share of vehicles classified as built to measure a quantity falls from 48.3 percent before 1990 to 31.4 percent after it, in the direction the first article predicted, and the difference is not established at this sample size, Fisher’s test giving 0.204. No negative result here matters more. The instrument model, the series’ organising claim, did not stop describing the designation in any way the record can detect. What changed demonstrably was who was aboard, who paid, and, twice, how the number was chosen.
The article is a synthesis and has no aircraft. Its subject is the designation system across the series, and its sources are the seventy earlier articles, the register of allocations those articles used, in a copy later than this article’s date whose differences from the version then current are stated under The Source Base, the editions of the numbering rule from 1962 to 2020, and a survey of 4,710 records on research aircraft as a class and the institutions and methods around them. It is written to answer the questions the first article asked, by name, and it states where the record does not bear the first article out.
The Questions the First Article Asked
The framing article closed by naming what this one would return to [X-Planes framing]. It asked four questions in its roadmap. What the designation became, why the clusters fall where they do, why the parallel unmanned series consumed numbers from the same pool, and whether the instrument model still describes what an X designation means. Earlier in the same article it made four further claims that it left to be tested.
- That the assignment of numbers to programmes is not total, not a function, not injective and not monotone, and that each failure records an institutional fact. Its examples were eleven unassigned numbers, the X-44 and the X-42 as failures to be a function, four programmes each holding two numbers as failures of injectivity, and the X-49 allocated after the X-50 as the one failure of monotonicity.
- That allocations cluster in time, with an index of dispersion by decade well above one, a claim it made without computing the index.
- That roughly two fifths of the designations support a full engineering treatment, the rest being cancelled, classified or administrative.
- That the proportion of programmes with a purpose other than returning information appears to rise over the period covered.
This article answers each of the eight. The answers are collected under Comparison With Ground Prediction, which in this article compares the first article’s predictions with the record the series produced, since the first article was written before any of the aircraft articles and stands to them as a prediction stands to a flight.
The Binding Unknown of a Synthesis
Every earlier article named the single unknown its vehicle existed to resolve. This article’s binding unknown is what an X number asserts about the thing it is attached to, and the measurement that resolves it is a count over the seventy articles rather than a flight. The count can be made because each article recorded the same kinds of fact, and the count has a weakness, stated in Where the Framing Breaks Down. Because the data are the series’ readings of its sources, a systematic error in how the series read its subjects would reappear here as a finding.
The Series as a Data Set
How the Ledger Reads the Series
The ledger holds one record for each of the seventy earlier articles. A record holds the vehicle’s contractor, its sponsors, the date of its designation, the start of its programme, its first and last flights, its outcome, whether anyone flew aboard, what kind of vehicle it was, the article’s statement of its keystone, a classification of that keystone, the article’s comparison of ground prediction with flight, and, for a vehicle that never flew, the reason the article gives. Every value an article states carries the article’s line number and a verbatim quotation of between 20 and 300 characters. A value the article does not state is left empty.
Three fields are classifications rather than quotations. The keystone classification, the vehicle kind and the reason a vehicle never flew are readings of each article and are reported as readings. A further 21 coding decisions enter the counts, chiefly to record the design crew of vehicles that never flew, and each of those carries a quotation as well.
The Entry Year of a Number
Most early articles do not say when their number was assigned, because the record they read does not. The register of allocations that the later articles used, which Andreas Parsch compiles from data the Department of Defense has released, begins with allocations of 1997 [Parsch, DOD 4120.15-L Addendum], and the edition of the official list that it supplements gives no dates for its X rows [DOD 4120.15-L, 2004]. So the year a number entered the series has to be chosen from what is recorded, and the choice is made two ways.
The first, called P2 here, takes the register’s date of first allocation where the register has the number’s A model, then the article’s stated designation date, then the first flight, then the programme start. The second, called P1, takes the earliest of all four. P2 is closer to the date of the number and P1 is closer to the date of the programme, and every result that depends on time is computed under both and reported as a range. The X-26 has no recorded year under either and is left out of the timed counts, which cover 64 of the 65 numbers that went to a vehicle.
What the Ledger Holds
| Quantity | Count |
|---|---|
| Articles read | 70 |
| Design numbers covered | 76 |
| Articles about a number with no vehicle | 5 |
| Vehicle numbers that flew | 47 |
| Vehicle numbers built and not flown | 5 |
| Vehicle numbers not built | 12 |
| Vehicle numbers whose build state is unknown | 1 |
| Design crew recorded as crewed | 29 |
| Design crew recorded as uncrewed | 30 |

The five articles without a vehicle are the X-39, the X-52, the X-58, the X-67 and the block from X-69 to X-75, which together cover eleven numbers. The one vehicle whose build state is unknown is the X-63, whose article found it unknown whether any hardware was built [X-63].

Four Properties the Assignment Lacks
The first article wrote the designation system as a relation between numbers and programmes and asked whether it is total, whether it is a function, whether it is injective and whether it is monotone [X-Planes framing]. It answered no to all four and named its cases, and the series can now measure each failure. The second and third questions need to be kept apart, because the difference changes what the anomalies mean.
Writing the Assignment as a Relation
The assignment is safest written, as the first article wrote it, as a relation between the set of design numbers $D$ and the set of programmes $P$, with no assumption that it is a function,
\[R \subseteq D \times P, \qquad D = \{1, 2, \dots, 76\} \tag{1}\]where $(n, p) \in R$ means that design number $n$ was applied to programme $p$. The relation is a function on its domain only if no number names two programmes, or formally
\[(n, p) \in R \ \wedge \ (n, p') \in R \ \Rightarrow \ p = p' \tag{2}\]and it is injective only if no programme holds two numbers, the converse condition
\[(n, p) \in R \ \wedge \ (n', p) \in R \ \Rightarrow \ n = n' \tag{3}\]The first article kept these two conditions apart, and the distinction is not pedantry. A number with two vehicles is a record-keeping collision, and a programme with two numbers is the system counting something other than programmes.
Totality
The numbers with no programme are the X-39, which was reserved and never requested [X-39], the X-52, which was requested and refused [X-52], the X-58 and X-67, whose slots went to unmanned vehicles [X-58] [X-67], and the seven numbers from X-69 to X-75 [X-69 through X-75]. The register compiler’s page of missing designations states the first four in its own words, that the X-39 was reserved on 23 April 1997 and never formally requested, that the X-52A was disapproved because of possible confusion with the B-52 series, and that the X-58 and X-67 slots were skipped after the XQ-58A and XQ-67A were allocated [Missing USAF and DOD Aircraft Designations]. That is eleven, as the first article said, counting the X-23 as assigned because a vehicle flew under it, although the record holds no allocation request for it, so the share of the range that went to a programme is
\[\eta = \frac{\left| \{ n \in D : \exists p, \ (n, p) \in R \} \right|}{|D|} = \frac{65}{76} = 0.855 \tag{4}\]The first article’s count stands. What the series added is that the eleven are four different kinds of absence, and the unassigned set $U$ divides accordingly,
\[|U| = |U_{\text{reserved}}| + |U_{\text{refused}}| + |U_{\text{pool}}| + |U_{\text{block}}| = 1 + 1 + 2 + 7 = 11 \tag{5}\]with the X-39 reserved, the X-52 refused, the X-58 and X-67 taken into the drone pool and the seven of the block passed over. Counting the X-23 as unassigned instead, because no allocation request for it is recorded, changes the share by one number,
\[\eta' = \frac{64}{76} = 0.842 \tag{6}\]so the first article’s figure is right to within one number. Read in turn, the X-39 is a number reserved, never requested and never released, and so lost whichever came first, the sequence passing it or the programme’s end, the X-52 a number refused for possible confusion with the B-52, the X-58 and X-67 numbers consumed by another series, and the block a set of seven passed over at once so that one number could be chosen.
The Assignment Fails to Be a Function Twice
The X-44 names two aircraft, the tailless F-22 derivative called MANTA, for Multi-Axis No-Tail Aircraft, which was never built, and an unmanned flying wing that flew in 2001 and was kept out of public view until 2018 [X-44]. The X-42 names two vehicles four years apart, the Upper Stage Flight Experiment to which the number was allocated and a winged reusable booster to which industry applied it informally [X-42]. These are the first article’s two cases, and they are the two numbers for which the ledger records a quotation saying that one number was applied to two vehicles. The X-23 is a contested case of a different kind, a number generally attributed to a vehicle for which the record shows no allocation request [X-23], and the X-41 is a number whose authoritative survey doubts it applied to the vehicle usually paired with it [X-41].
The Assignment Fails to Be Injective Four Times
Four programmes each hold two numbers, the four pairs the first article named, and in every case the ledger has the earlier article’s sentence saying so.
| Programme | Numbers | What distinguishes the two |
|---|---|---|
| Atlas intercontinental ballistic missile | X-11 and X-12 | configuration, two engines against three [X-11] |
| Joint Strike Fighter concept demonstration | X-32 and X-35 | contractor |
| Navy unmanned combat air vehicle | X-46 and X-47 | contractor |
| Aerospike Rocket Integration and Suborbital Experiment | X-63 and X-64 | contractor |
The Atlas pair is the same airframe in two stages of development [X-12]. The other three pairs are distinguished by contractor alone, as the X-64 article observed of the X-63 and X-64, whose two register rows differ only in the firm [X-64]. Three of the four non-injective pairs therefore record a competition, the system issuing one number per bidder rather than one per programme. In that measurable sense the X designation counts contractors, and it began with the X-32 and X-35 of the Joint Strike Fighter competition, not with the X-63 and X-64 in 2022.
Monotonicity
The first article placed the one monotonicity failure at the X-49 and the X-50, and set the X-76 apart as a skip. The X-76A was allocated on 20 October 2025, after the X-68A of 20 August 2025 and after every lower number, dates that only the later copy of the register carries [Parsch, DOD 4120.15-L Addendum]. What the X-76 breaks is consecutiveness, the expectation that each new number is one more than the last. Monotonicity asks only that a higher number never be allocated before a lower one, stated as
\[n < n' \ \Rightarrow \ t(n) \le t(n') \tag{7}\]and the register lets it be tested directly for the numbers whose first allocation it records. Twenty-three research design numbers enter the test, being those whose first row in the register is the A model, which excludes the X-37 and X-40 because the register’s rows for them are later series. The agreement between the order of the numbers and the order of their dates is measured by Kendall’s rank correlation [Kendall 1938],
\[\tau = \frac{C - Q}{\binom{m}{2}} \tag{8}\]where $C$ counts the pairs whose number and date are in the same order, $Q$ the pairs in opposite order, and $m$ the number of design numbers. With $m = 23$ there are 253 pairs, of which 250 are concordant, 1 is discordant and 2 are tied on date, so
\[\tau = \frac{250 - 1}{253} = 0.984 \tag{9}\]with every pair accounted for by the identity
\[C + Q + T = \binom{m}{2}, \qquad 250 + 1 + 2 = 253 \tag{10}\]where $T$ counts the pairs allocated on the same day.
The single discordant pair is the X-49 and the X-50, the first article’s case. The X-50A was allocated on 13 February 2002 and the X-49A on 23 May 2003. The two tied pairs are the X-46A and X-47A, allocated together on 14 May 2001, and the X-63A and X-64A, allocated together on 20 April 2022, which are two of the non-injective pairs above.
Every Skip Has a Recorded Cause
A number that is not one more than the highest number already allocated is either a skip or a backfill. Writing $h_k$ for the highest design number allocated before the $k$-th allocation and $n_k$ for the number it received, the advance is
\[a_k = n_k - h_k, \qquad h_k = \max_{j < k} n_j \tag{11}\]and a counter would give $a_k = 1$ every time. The share of advances equal to one is
\[s_1 = \frac{\left| \{ k : a_k = 1 \} \right|}{K} = \frac{16}{22} = 0.727 \tag{12}\]over the register’s 22 research advances, the figure the X-67 article measured [X-67]. The remainder are five skips and one backfill, and the series has found the cause of every one of them.
| Number | Advance | Cause recorded in the series |
|---|---|---|
| X-50A | 2 | the number 50 was requested because the aircraft would be a fifty-fifty marriage of helicopter and aeroplane [Parsch, Boeing X-50 Dragonfly] [X-49] |
| X-49A | -1 | the number passed over for the X-50 was assigned to the next request [X-69 through X-75] |
| X-53A | 2 | X-52 was refused for possible confusion with the B-52 [X-53] |
| X-59A | 2 | the number 58 had gone to the XQ-58A [X-58] |
| X-68A | 2 | the number 67 had gone to the XQ-67A [X-67] |
| X-76A | 8 | DARPA chose 76 as a deliberate nod to 1776 [DARPA X-76 announcement] |
The walk obeys an identity that gives the skipped numbers a second route. The high-water mark moves only when an advance is positive, so the positive parts of the advances telescope to the span of the walk,
\[\sum_{k=1}^{K} \max(a_k, 0) = h_{\text{last}} - h_{\text{first}} = 76 - 44 = 32 \tag{13}\]and each advance greater than one passes over $a_k - 1$ numbers. Writing $B$ for the numbers later backfilled, the numbers permanently skipped in the register era are
\[\sum_{k=1}^{K} \max(a_k - 1, 0) - B = 11 - 1 = 10 \tag{14}\]which equals the count of design numbers between 44 and 76 with no research row in the register, the 52, the 58, the 67 and the seven from 69 to 75, counted directly. The two routes could have disagreed, and they do not.
Two of the five skips are numerology, one is a refusal on grounds of confusability, and two are numbers taken by the unmanned series. No skip in the register era is unexplained, although two of them, the 58 and the 67, followed from the rule rather than from anyone’s choice, and they are the first and second research numbers skipped under the issue of 16 May 2014, which made a skip permanent [X-67]. The first chosen number in the research series is the X-50 of 2002, not the X-76 of 2025, as the X-69 through X-75 article recorded, which found the number asked for because of its meaning by DARPA in the register’s note, by Boeing in its programme manager’s account to the National Aeronautics and Space Administration, NASA, and by both together in the compiler’s directory entry for the aircraft, which calls the concept a 50/50 mix of helicopter and fixed-wing aircraft [X-69 through X-75] [Parsch, Boeing X-50 Dragonfly] [Parsch, DOD 4120.15-L Addendum]. What this article adds is that the only monotonicity failure in the register is that choice’s direct consequence. The X-76 is the second instance of a practice the series had already met, and what is new about it is that the choice was announced.
When the Numbers Came
The first article asserted that allocations cluster and did not compute the measure it named. It is computed here. Let $x_j$ be the number of designations whose entry year falls in decade $j$, over the $J = 9$ decades from the 1940s to the 2020s. The index of dispersion is the ratio of the sample variance to the mean,
\[\mathcal{D} = \frac{S^2}{\bar{x}}, \qquad \bar{x} = \frac{1}{J} \sum_{j=1}^{J} x_j, \qquad S^2 = \frac{1}{J - 1} \sum_{j=1}^{J} \left( x_j - \bar{x} \right)^2 \tag{15}\]and it is 1 in expectation when counts arise from a Poisson process, a process with no memory and no clustering. Under the null hypothesis of a constant rate the statistic
\[\chi^2 = (J - 1)\,\mathcal{D} \tag{16}\]follows a chi-square distribution with $J - 1$ degrees of freedom, which turns the index into a test [Fisher, The Significance of Deviations from Expectation in a Poisson Series, 1950] [Cochran 1954].
| Decade | Entries under P2 | Entries under P1 |
|---|---|---|
| 1940s | 3 | 9 |
| 1950s | 16 | 10 |
| 1960s | 6 | 7 |
| 1970s | 2 | 2 |
| 1980s | 2 | 1 |
| 1990s | 9 | 16 |
| 2000s | 14 | 8 |
| 2010s | 5 | 7 |
| 2020s | 7 | 4 |
Under P2 the mean is 7.11 per decade and the variance 25.61, so
\[\mathcal{D}_{P2} = \frac{25.61}{7.11} = 3.60, \qquad \chi^2 = 8 \times 3.60 = 28.8 \tag{17}\]with an upper-tail probability of 0.000342, and under P1
\[\mathcal{D}_{P1} = \frac{20.61}{7.11} = 2.90, \qquad \chi^2 = 8 \times 2.90 = 23.2 \tag{18}\]with probability 0.00313. For an even number of degrees of freedom the chi-square tail has a closed form, which gives a second route,
\[\Pr\left(\chi^2_{8} > x\right) = e^{-x/2} \sum_{i=0}^{3} \frac{(x/2)^i}{i!} \tag{19}\]and at $x = 28.8$ it gives 0.000342 again. The first article’s claim holds under both datings. The allocations cluster, and a constant-rate process would produce counts this uneven less than one time in three hundred.
The first article placed two clusters and one gap, and the counts show both clusters and the gap. It put clusters in the late 1940s and 1950s and in the late 1990s and 2000s, with a pronounced gap through the 1970s and early 1980s. The counts hold no third dense period, the 2010s and 2020s holding 5 and 7 numbers under P2 against a mean of 7.11. The late 1940s and the 1950s hold the rocket research aircraft and the Air Force’s missile and propulsion testbeds. The 1970s and 1980s together hold four numbers under P2. The 1990s and 2000s hold the second dense period, and the ledger shows what it was made of. Under P2 the 1990s hold the X-31, X-33, X-34, X-36, X-38, X-40, X-41, X-42 and X-44, six of them reusable-launch, entry or hypersonic vehicles, and the 2000s hold the Joint Strike Fighter pair, dated by first flight because their articles give no designation date, the X-37 and X-43, the unmanned combat air vehicle demonstrators from the X-45 to the X-47, and the numbers from the X-48 to the X-55. NASA’s inventory of 2003 describes the same shape in words, almost thirty designations from the late 1940s to the late 1970s, then largely nothing, then a resurgence in the mid to late 1990s [Jenkins et al. 2003]. On the cause the counts qualify the first article, since the clusters are better described as institutional than as budgetary, and the second one coincides with new sponsors entering the series. The next section takes up those sponsors.
Who Paid
The first article described a tripartite arrangement in which a military service supplied the requirement and the money, a contractor the airframe, and the National Advisory Committee for Aeronautics, NACA, or its successor the National Aeronautics and Space Administration, NASA, the research programme [X-Planes framing]. The ledger records each article’s named sponsors, which were sorted into classes. The diversity of sponsorship in each decade is measured by the Shannon entropy of the sponsor mentions [Shannon 1948],
\[H = - \sum_{i} q_i \log_2 q_i \tag{20}\]where $q_i$ is the share of the decade’s sponsor mentions falling in class $i$. A decade whose every mention is one class has $H = 0$, and a decade spread evenly over eight classes has $H = 3$ bits.
| Decade | Vehicle numbers | Sponsor classes named | Entropy in bits |
|---|---|---|---|
| 1940s | 3 | 3 | 1.46 |
| 1950s | 16 | 3 | 1.33 |
| 1960s | 6 | 5 | 2.05 |
| 1970s | 2 | 2 | 1.00 |
| 1980s | 2 | 2 | 0.92 |
| 1990s | 9 | 7 | 2.35 |
| 2000s | 14 | 7 | 2.63 |
| 2010s | 5 | 4 | 1.84 |

The 1950s are the least diverse decade with more than a handful of entries, 16 numbers whose sponsor mentions are mostly the Air Force, with NACA and the Navy alongside. Their 26 mentions are 16 Air Force, 6 NACA and 4 Navy, so
\[H_{1950s} = - \left( \tfrac{16}{26} \log_2 \tfrac{16}{26} + \tfrac{6}{26} \log_2 \tfrac{6}{26} + \tfrac{4}{26} \log_2 \tfrac{4}{26} \right) = 1.33 \ \text{bits} \tag{21}\]Entropy grows with the number of classes as well as with their balance, so the balance alone is measured by the evenness, the entropy divided by its maximum for the classes present, as Pielou defined it for biological collections [Pielou, The Measurement of Diversity in Different Types of Biological Collections, 1966],
\[J' = \frac{H}{\log_2 r} \tag{22}\]with $r$ the number of classes named. By evenness the 1950s, $J’ = 0.842$, and the 1990s, at 0.838, are the least balanced decades, against 0.937 for the 2000s, so the Air Force’s dominance of the first dense period is a fact about balance as well as about the number of sponsors, although the 1990s spread their mentions as unevenly over seven classes. The 1990s and 2000s are the most diverse, with seven classes each, because the period added DARPA, the Air Force Research Laboratory, foreign and joint offices and NASA as a leading sponsor of its own vehicles. The 2020s add the Space Force, which appears in the register’s research rows exactly twice, both for the X-63 and X-64 [X-63]. The entropy is a description of a small sample and no test is attached to it, since a decade with eight sponsor mentions cannot carry one. What it shows is that the tripartite arrangement of the first decades had become a market of sponsors by the 1990s.
From a Pilot to Nobody Aboard
This is the change the record establishes most firmly. The first article said the meaning of the prefix drifted from a crewed research aircraft to unmanned demonstrators and asked for the drift to be counted rather than asserted. The ledger records the design crew of 59 of the 65 vehicle numbers.
| Entry before 1990 | Entry from 1990 |
|---|---|
| 20 crewed, 8 uncrewed | 8 crewed, 22 uncrewed |
The crewed share before 1990 is $\hat{\pi} = 20/28 = 71.4$ percent and from 1990 it is $8/30 = 26.7$ percent. Each proportion carries a 95 percent interval by the method of Wilson, which behaves well at small samples and near zero or one [Wilson 1927],
\[\frac{\hat{\pi} + \dfrac{z^2}{2N} \pm z \sqrt{\dfrac{\hat{\pi}(1 - \hat{\pi})}{N} + \dfrac{z^2}{4N^2}}}{1 + \dfrac{z^2}{N}} \tag{23}\]with $z = 1.96$ and $N$ the sample size. The intervals are 52.9 to 84.7 percent and 14.2 to 44.4 percent, and they do not overlap. The exact test, which Fisher set out for the two-by-two table [Fisher 1935], asks how probable a table this lopsided would be if the crewed share had not changed. Holding the row and column totals of the two-by-two table fixed, the conditioning that Fisher’s earlier treatment of contingency tables made standard [Fisher, On the Interpretation of Chi-Square from Contingency Tables, 1922], the probability of exactly $a$ crewed vehicles in the early group is hypergeometric,
\[\Pr(a) = \frac{\dbinom{a + b}{a} \dbinom{c + d}{c}}{\dbinom{N}{a + c}} \tag{24}\]where $a$ and $b$ are the early crewed and uncrewed counts, $c$ and $d$ the late ones, and $N$ their total. Summing every table no more probable than the observed one,
\[p = \sum_{x \,:\, \Pr(x) \le \Pr(a)} \Pr(x) \tag{25}\]gives Fisher’s two-sided probability of 0.00138. The size of the change is better stated as a difference in shares and as an odds ratio than as a probability. The difference is
\[\hat{\pi}_{\text{early}} - \hat{\pi}_{\text{late}} = 0.714 - 0.267 = 0.448 \tag{26}\]and the odds ratio, the odds of a crewed vehicle before 1990 divided by the odds after, is
\[\psi = \frac{a d}{b c} = \frac{20 \times 22}{8 \times 8} = 6.88 \tag{27}\]with a 95 percent interval by Woolf’s method on the logarithmic scale [Woolf 1955],
\[\exp\left( \ln \psi \pm 1.96 \sqrt{\tfrac{1}{a} + \tfrac{1}{b} + \tfrac{1}{c} + \tfrac{1}{d}} \right) = 2.17 \ \text{to} \ 21.8 \tag{28}\]A vehicle entering the series before 1990 had about seven times the odds of carrying a pilot, and the interval excludes one by a wide margin.
The uncrewed vehicles of the two periods were different kinds of thing, and separating them sharpens the result. The uncrewed X vehicles before 1990 were missiles, rockets and one subscale entry vehicle, the X-7, X-8, X-9, X-10, X-11, X-12, X-17 and X-23, and only the X-10 was an aeroplane. Among aircraft alone, 18 of 19 before 1990 carried a pilot and 8 of 22 from 1990 did, Fisher’s test giving 0.000103, and the odds ratio is
\[\psi_{\text{aircraft}} = \frac{18 \times 14}{1 \times 8} = 31.5 \tag{29}\]with a Woolf interval of 3.51 to 282, wide because a single uncrewed aircraft before 1990, the X-10, is the whole of the early uncrewed cell.
Six vehicles have no design crew in their articles, and the most adverse reading assigns each of them against the finding, an early one counted uncrewed and a late one crewed. Fisher’s probability then rises to 0.014 for all vehicles and 0.00171 for aircraft, so the conclusion does not depend on the readings the articles left open. An independent compilation agrees wherever both say anything. The register compiler’s directory groups every unmanned military vehicle given an X designation after 1963 in one appendix, which lists 19 research numbers and notes the NASA-only X-33, X-34, X-38 and X-43 as outside its scope [Parsch, Directory of U.S. Military Rockets and Missiles, Appendix 4]. The ledger codes 17 of the 19 uncrewed, none crewed, and leaves the X-41 and X-51 unstated, and it codes all four NASA-only vehicles uncrewed. Reading the two unstated vehicles as the appendix does would add two uncrewed vehicles after 1990 and strengthen the result. The register’s descriptions agree from a third direction. The X-60 article counted 12 of the 31 research rows in the register describing an uncrewed vehicle, and none carrying the Q symbol that marks a drone [X-60]. A research vehicle takes X and a number whether or not anyone is aboard, to use the X-60 article’s phrasing. That sentence answers the question of what the prefix became in its first sense.
What the Aeroplanes Were For
The first article’s model treats a research aircraft as an instrument, and its fourth failure mode predicted that the share of programmes with some other purpose would rise. The ledger’s keystone classifications test that. Each article’s stated keystone is classified by a reading of the article.
| Keystone class | Vehicle numbers |
|---|---|
| measurement of a quantity ground facilities could not settle | 25 |
| demonstration that known pieces work together | 27 |
| a central result that is analytical, the vehicle not needed for it | 5 |
| winning a procurement | 4 |
| developing a weapon or its airframe | 3 |
| no research question | 1 |
Fewer than half the vehicle numbers in the series are classified as measurement, 25 of 65, a figure that already qualifies the instrument model,
\[\hat{\pi}_{\text{measure}} = \frac{25}{65} = 0.385, \qquad \text{95 percent interval } 0.276 \text{ to } 0.506 \tag{30}\]and this share is the basis for saying that the model describes about two fifths of the vehicles. Before 1990 the measurement share is 14 of 29, 48.3 percent with a Wilson interval of 31.4 to 65.6 percent, and from 1990 it is 11 of 35, 31.4 percent with an interval of 18.6 to 48.0 percent. The fall is in the predicted direction and Fisher’s test gives 0.204, so a difference of this size would arise by chance about one time in five. The first article’s prediction is therefore not confirmed and not refuted. It is unestablished at the size of the series, and the size of the shortfall can be stated. For two shares $\hat{\pi}_1$ and $\hat{\pi}_2$ with mean $\bar{\pi}$, the number of vehicles needed in each period for a two-sided test at the 5 percent level to detect the difference four times in five is, by the normal approximation for two independent proportions [Fleiss et al. 1980],
\[N^{*} = \frac{\left( z_{0.975} \sqrt{2 \bar{\pi} (1 - \bar{\pi})} + z_{0.80} \sqrt{\hat{\pi}_1 (1 - \hat{\pi}_1) + \hat{\pi}_2 (1 - \hat{\pi}_2)} \right)^2}{\left( \hat{\pi}_1 - \hat{\pi}_2 \right)^2} \tag{31}\]with $z_{0.975} = 1.96$ and $z_{0.80} = 0.84$. Substituting the observed shares,
\[\hat{\pi}_1 = 0.483, \qquad \hat{\pi}_2 = 0.314, \qquad \bar{\pi} = 0.399 \tag{32}\]gives $N^{*} = 131$ against the 29 and 35 vehicles the two periods hold. The series is about a quarter of the size the question needs.
What does show in the record is that the departures from the instrument model are old. The X-9, X-11 and X-12 were weapon development airframes in the 1950s, the X-16 was a reconnaissance aeroplane whose designation served as security cover [X-16], and the X-27 was always intended as a prototype for production [X-27]. NASA’s 2003 inventory makes the same point about the Joint Strike Fighter demonstrators, recording criticism that the designation had been corrupted by prototypes of operational aircraft and answering that the practice was not new, with the X-11, X-12 and X-27 as precedent [Jenkins et al. 2003]. The designation has carried procurement since its first decade, and the series cannot show that it carries more of it now.
Eighteen Vehicles That Did Not Fly
Of the 65 vehicle numbers, 18 had not flown by their articles’ dates, being 12 not built, 5 built and not flown, and the X-63, whose build state is unknown. Three of them belong to programmes still running at their dates, the X-65, X-68 and X-76, and are not failures of anything. That leaves fifteen vehicles whose programmes ended without a flight, or 23 percent of the vehicle numbers in the series,
\[\hat{\pi}_{\text{ended unflown}} = \frac{15}{65} = 0.231, \qquad \text{95 percent interval } 0.145 \text{ to } 0.346 \tag{33}\]so somewhere between about one in seven and about one in three X vehicles was never asked a question in the air.
The series’ articles set out a taxonomy of the reasons, and the ledger lets it be counted.
| Reason the article gives | Vehicles |
|---|---|
| absence of demand, nobody wanted the aeroplane | X-6, X-20, X-27 |
| absence of knowledge, the thing to be shown could not be shown achievable first | X-30, X-42 |
| an answer nobody wanted, the demonstrator worked and its number did not close | X-33 |
| ready and scrapped, the vehicle was finished and never asked a question it could fail | X-34, X-60 |
| superseded, cancelled for another programme, or no reason recorded | X-16, X-46, X-54, X-57, X-63, X-64, X-66 |
The first four rows are the series’ own classes, set out by the X-33 and X-34 articles when they completed a set of four [X-33] [X-34]. The ledger adds two things to them. The X-60 joins the X-34 as a vehicle that reached its last reported milestone before flight and stopped [X-60], so the X-34 is not the only one that was ready. And the fifth row is the largest, seven of fifteen. A vehicle cancelled for another programme, or stopped with no recorded reason, does not fit a taxonomy built from programmes whose reasons were argued in public. The finding concerns the record rather than the vehicles. The later the programme, the less often its end is explained, since six of the seven in the fifth row entered the series after 2000.
The Number Before and After the Flight
The series met a set of orderings between a designation and its aeroplane, and the late articles collected them. A number allocated before the aeroplane existed is the expected case. The X-53 was designated after it stopped flying, the X-54 was designated and never flew, the X-55 flew and was designated 139 days later, and the X-62 was designated after twenty-nine years of flight under another name [X-62]. Collected together, these read as a pattern of the late series, and the ledger shows that the pattern is older.
Writing $\Delta t$ for the interval from first flight to designation,
\[\Delta t = t_{\text{designation}} - t_{\text{first flight}} \tag{34}\]a positive value means the aeroplane flew first. Of the 22 vehicles that flew and whose articles date both events, 6 have $\Delta t > 0$,
\[\hat{\pi}_{\Delta t > 0} = \frac{6}{22} = 0.273, \qquad \text{95 percent interval } 0.132 \text{ to } 0.482 \tag{35}\]and the three intervals the record dates to the day are
\[\Delta t_{\text{X-28}} = 349, \qquad \Delta t_{\text{X-55}} = 139, \qquad \Delta t_{\text{X-62}} = 10658 \ \text{days} \tag{36}\]spanning almost two orders of magnitude.
| Number | First flight | Designation | Interval |
|---|---|---|---|
| X-8 | 2 December 1949 | May 1951 | about seventeen months |
| X-9 | April 1949 | 1951 | about two years |
| X-28A | 12 August 1970 | 27 July 1971 | 349 days |
| X-53A | late 2002 | 16 August 2006 | more than a year after the last flight in March 2005 |
| X-55A | 2 June 2009 | 19 October 2009 | 139 days |
| X-62A | 9 April 1992, by one account | 14 June 2021 | 10,658 days, or 29.2 years |
NASA’s fact sheet for the X-53’s programme dates its first research flights to late 2002 and its second phase’s last to March 2005 [NASA, Active Aeroelastic Wing Flight Research, FS-2005-03-061 DFRC]. The earliest are the X-8 and the X-9, a sounding rocket and a subscale development article for a guided missile, both designated retrospectively in 1951 when the research-and-test-vehicle series they belonged to was folded into the X series [X-8] [X-9] [X-10]. The compiler’s directory gives both redesignations, the RTV-A-4 becoming the X-9 in 1951 with its flight tests continuing to January 1953, and the RTV-A-5, ordered in 1950, becoming the X-10 in 1951 two years before its first flight [Parsch, Bell RTV-A-4/X-9 Shrike] [Parsch, North American RTV-A-5/X-10]. The X-7 is part of the same fold. It predates its designation by five years, although its first launch and its designation fall in the same year [X-7]. The X-8 article dates the redesignation of the RTV-A-1 to 1951, and to May 1951 on the compiler’s account, seventeen months after the first Air Force flight of 2 December 1949, and every dated reading it found falls after that flight, the 1949 of one list being a first-flight year and the 1955 given elsewhere having no support in the sources it read [X-8]. The X-28A is a homebuilt aeroplane the Navy watched fly, bought, and designated, on a date its article takes from a single reported account, so the X designation was applied to a purchase, and the research it marked was an evaluation of something already built [X-28]. A designation given after flight therefore spans the series, from 1951 to 2021, and the register has recorded outcomes as well as authorising attempts from its first decade.
How Answerable the Question Was
The series’ articles describe a spectrum of how answerable a research question was, and the late articles add a second, of how much of the question could be settled without the aeroplane. The ledger’s ground-comparison field puts a count on the first. For each of the 47 vehicles that flew, the ledger records what the article’s section headed Comparison With Ground Prediction concluded.
| What the comparison concluded | Vehicles that flew |
|---|---|
| flight confirmed the ground prediction | 6 |
| flight confirmed part and contradicted part | 23 |
| flight contradicted the prediction outright | 0 |
| the article compared nothing with flight | 14 |
| no flight data reached the article | 4 |
No article recorded flight contradicting its ground prediction outright, and the commonest result is a mixed one, 23 of 47. Among the 29 articles whose comparison reached flight data the mixed share is
\[\hat{\pi}_{\text{mixed}} = \frac{23}{29} = 0.793, \qquad \text{95 percent interval } 0.616 \text{ to } 0.902 \tag{37}\]so a comparison that reached flight data more likely than not found part of the ground prediction wrong. A mixed verdict is the outcome the first article’s information model predicts. A flight programme exists because some quantity is outside what ground facilities settle, and such a programme naturally returns agreement on the quantities the facilities could settle and disagreement on the residue. The number of comparisons that compared nothing, 14, is a fact about the record. They are concentrated among the missile testbeds, the competitors and the uncrewed demonstrators, for which the public record holds flight dates and few flight measurements.
The contemporary literature supplies a clean instance of a mixed verdict on one of the series’ aeroplanes. Six independent predictions of the X-56A’s body freedom flutter all agreed with one another and all placed the flutter speed 10 to 20 knots above the speed the aeroplane measured [Ouellette et al. 2026]. The methods agreed on the physics and disagreed with flight on the number, the residue a research aircraft exists to measure.
The Information a Programme Returns
The first article sized a programme by the information it returns. For a quantity known before the programme with standard deviation $\sigma_0$ and after it with standard deviation $\sigma_n$, the information gained is
\[I = \frac{1}{2} \log_2 \frac{\sigma_0^2}{\sigma_n^2} \tag{38}\]in bits, and the X-1 example in the first article, whose variance ratio was 400, returned
\[I_{\text{X-1}} = \frac{1}{2} \log_2 400 = 4.32 \ \text{bits} \tag{39}\]on one number [X-Planes framing]. The relation’s lesson for a synthesis is that the series can show information returned only for the vehicles whose comparison reached flight data, 29 of the 65 vehicle numbers when the confirmed and mixed rows are taken together. The remainder are not failures of the model. Many of them flew and returned data that the public record does not report, and the model has nothing to measure them with.
The Pool Shared With the Drones
The first article asked why the parallel unmanned series consumed numbers from the same pool, and the series found an answer in the rule itself. The rule as issued on 16 May 2014 [X-67] and reissued jointly in 2020 [Department of the Air Force Instruction 16-401, 2020] defines the next designator from the last approved design number in the basic mission series and refuses requests in reverse or skipped sequences, a written request being sent by the programme office to a single Air Force control point, which recommends a designation for decision at Air Force headquarters [Allocation of Official Aerospace Vehicle MDS Designations], and the X-67 article showed what that does to a number borrowed by another series [X-67]. A design number borrowed for an unmanned vehicle should equal its source series’ next number at the moment of the borrowing and no other series’, and across six out-of-sequence unmanned numbers tested against twenty basic missions, the test fires twice and names the research series both times, for the XQ-58A and the XQ-67A. Nobody had to decide to skip the X-67, and somebody had to ask for the X-68.
The register’s notes make the source explicit. The compiler’s note on the XQ-58A records that the out-of-sequence number 58 of the Kratos Valkyrie was taken from the X series and that there is no X-58, and the note on the XQ-67A states that its number was taken from the X series [Parsch, DOD 4120.15-L Addendum]. In the register, nine of the design numbers among its 69 Q rows are out of the Q sequence, and the compiler’s notes give a source for five of them,
\[\frac{9}{69} = 0.130 \tag{40}\]of the drone rows. Two came from the research series, the 58 and the 67. The RQ-170’s number came from the manufacturer’s project number, the YFQ-48A’s apparently follows the F-47 in the fighter series, and the XRQ-73A’s was probably chosen to follow the XRQ-72A. For the 35, the 42, the 44 and the 72 the notes give no source or call it unclear [Parsch, DOD 4120.15-L Addendum]. The YFQ-48A is a founding-year number’s descendant, a drone numbered to follow a fighter numbered in part for 1947.
The reason the pool is shared is therefore not that the X and Q series are one series. It is that an unmanned research vehicle sits on the boundary between them, and in two cases the services resolved that boundary by giving such a vehicle the drone’s mission symbol and the research series’ number. The X-60 article stated the converse, that a research vehicle takes X and a number whether or not anyone is aboard [X-60]. Both resolutions coexist in the register, which is why the pool is shared at all.
The Number Became a Message
The register’s copy of 23 August 2026 holds three design numbers chosen to match the last two digits of a founding year, and all three fall within 329 days. The YMV-75A was allocated to the Army on 25 November 2024 for 1775, the F-47A went to the Air Force for 1947, and the X-76A went to DARPA on 20 October 2025 for 1776 [X-69 through X-75], so the class spans
\[t(\text{X-76A}) - t(\text{YMV-75A}) = 329 \ \text{days} \tag{41}\]from first to last. The Army’s designation announcement explains the 75 as commemorating the Army’s founding year, 1775 [Army MV-75 announcement]. The Air Force’s contract announcement for the F-47 [Air Force F-47 announcement] was followed by a statement giving the 47 three meanings, the P-47, the founding year of the Air Force and the 47th President, so the founding year is one meaning among three, and released public affairs correspondence names General Allvin as the officer who made the decision [Air Force public affairs correspondence on the F-47] [X-69 through X-75]. DARPA’s X-76 announcement [DARPA X-76 announcement] and Bell’s release of the same day reporting the official designation [Bell X-76 release] complete the public record of the three. The X-69 through X-75 article measured how improbable the X-76’s seven unreleased predecessors would be under the series’ allocation rate, a Poisson tail of 1.83e-10, and found that the 2020 rule provides no instrument for reserving a block.
The section on skips above shows that the practice is older than the class. The X-50 of 2002 was chosen for a numerical pun, the fifty-fifty marriage of helicopter and aeroplane, and the register’s note on the X-50A records that DARPA explicitly requested the number, while Boeing’s account gives the request as its own [Parsch, DOD 4120.15-L Addendum] [X-49]. The allocation procedure leaves room for a chosen number. The compiler’s account of it states that a written request must include a suggestion for the new designation, that a number can be requested when the requester particularly likes it, and that the control point’s recommendation may or may not be the designation the requester proposed [Allocation of Official Aerospace Vehicle MDS Designations]. A chosen number is therefore a suggestion the deciding office accepted, and since the issue of 16 May 2014 the rule’s written discretion to skip is what lets it accept one out of sequence, a provision the issue in force in 2002 did not contain [X-52]. What changed between 2002 and the X-76 is the publicity. The X-50’s reason is recorded in a compiler’s note and a contractor’s account, while the X-76’s was the headline of the announcement. A number that is announced as a message is a number whose purpose includes being read by the public, a different object from a sequence index read by a records office.
The Register Stopped Being the Government’s Voice
The X-61 article made the finding this synthesis most needs, a finding about the register rather than any aeroplane. The register’s compiler states that no complete official data on designations assigned after October 2018 is available and that for later allocations the official description is no longer releasable, so such descriptions are marked as the compiler’s own [X-61]. Among the rows the register dates in full, the last official research description is the X-60A’s of 7 September 2018 and the first unofficial one is the X-61A’s of 6 June 2019.
The register’s markup has three states, not two. Counted from all 539 rows of the register, the 31 research rows divide into 21 official, 7 whose description cell is the compiler’s, 2 whose whole row is absent from officially released data, and 1 partly marked [Parsch, DOD 4120.15-L Addendum],
\[21 + 7 + 2 + 1 = 31, \qquad \frac{21}{31} = 0.677 \tag{42}\]so about two thirds of the register’s research rows carry the government’s own wording throughout. On this article’s date, before the X-68A and X-76A rows were added, the share was 21 of 29, or 0.724. For the rows the register dates in full, the series divides at the X-60, the official description of what each aeroplane was for being available up to it and withheld after it. Two rows with partial dates are unofficial in the stronger sense of being absent from released data altogether, the X-37B of 2006 among them. What is withheld after the X-60 is a single sentence, since the date, designation, contractor, engine and sponsor remain official.
And the register lags the allocations by months. The X-68A and X-76A rows did not appear in the public register until between 15 January and 1 February 2026, by archived copies, the capture of 15 January 2026 showing neither row and that of 1 February 2026 showing both [Parsch, DOD 4120.15-L Addendum, as archived on 10 December 2025] [Parsch, DOD 4120.15-L Addendum, as archived on 15 January 2026] [Parsch, DOD 4120.15-L Addendum, as archived on 1 February 2026], which the X-69 through X-75 article established. Writing $\Lambda$ for the interval from allocation to first public appearance, the two captures bound it,
\[148 < \Lambda_{\text{X-68A}} \le 165, \qquad 87 < \Lambda_{\text{X-76A}} \le 104 \ \text{days} \tag{43}\]so the register published each row three to five months after the number existed. The newest research numbers were invisible in the public register on the dates of the articles that describe them, and the series’ account of what was knowable when has to use the date a row first appeared, not the date of the allocation.
The federal award record, which records what the government paid for these aeroplanes, has three times shown no use for the number. The X-62 article found 73 transactions against the aeroplane from February 2014 to September 2025, totalling 29,085,924.37 dollars, and not one of them writes down the number allocated in June 2021 [X-62] [USAspending]. The X-63 article found a vehicle bought under an other transaction agreement, which a search of the federal award record under the names the programme is known by does not find [X-63], for a programme the Air Force Research Laboratory’s fact sheet describes as its most ambitious technology demonstrator yet in its modular rocket portfolio [Air Force Research Laboratory, ARISE fact sheet], and in the X-76 article Bell’s instrument is missing from the award record [X-76]. A designation is a claim about a vehicle’s purpose made by one part of a government to another, and the parts that buy the fuel have no use for it.
What the Record Measures
The first article said the record thins sharply after about 2000, and a direct count of the thinning by designation is not usable. A count of the reports-server records whose titles name each design number from 1 to 76 is confounded in three ways. The quoted query for the X-1 is dominated by X-ray sources named in the same form, the server indexes X-43 and X-43A as different words and returns 45 and 57 records for them, and the X-24’s first hundred records contain no title naming it. A title count by designation measures the server’s tokeniser as much as the literature, and no number from such a count appears in this article.
What the series can say is narrower and is measured. The X-33 article found that 71 of the 78 survey titles carrying its designation predate 2002 and that the latest is dated 2017, and the X-34 article that 37 of the 39 research records whose titles carry its designation date from 2001 or earlier, both programmes having been cancelled in 2001 [X-33] [X-34], and the X-32 article counted exactly one record carrying the losing competitor’s designation in a cited set of 3,528 against 38 for the winner’s production designation [X-32]. In those three cases the documentary trace of a vehicle measures how long its programme survived and whether it won, more than what it contributed. The NASA cost engineers who built a parametric model of X-plane costs reached the same limit from the other side, ending their account with a call for accurate and traceable cost data from historical X-plane records [Sterk et al. 2016].
Comparison With Ground Prediction
In the earlier articles this section set a ground facility’s prediction beside what flight returned. In this one the ground prediction is the first article, written before any of the seventy aircraft articles, and the flight is what those articles found. Each of the first article’s testable claims is set beside the measurement.
| The first article’s claim | What the series measured | Verdict |
|---|---|---|
| eleven numbers in the range have no programme | eleven, of four different kinds | confirmed |
| the assignment is not a function, at the X-44 and the X-42 | both numbers are recorded as naming two vehicles | confirmed |
| injectivity fails at four pairs | the same four pairs, three of them distinguished by contractor alone | confirmed |
| monotonicity fails once, the X-49 after the X-50, and the X-76 is a skip | that pair is the one discordant pair of 253, Kendall’s $\tau$ of 0.984 | confirmed |
| allocations cluster, with an index of dispersion well above one | 2.90 to 3.60, with $p$ of 0.000342 to 0.00313 | confirmed |
| clusters in the late 1940s and 1950s and the late 1990s and 2000s, with a gap in the 1970s and early 1980s | both clusters and the gap | confirmed |
| the clusters track procurement and budget cycles | they coincide with new sponsors entering, which is institutional rather than budgetary | partly confirmed |
| roughly two fifths of the designations support a full treatment | 47 of 76 numbers went to something that flew, about three fifths | the share of real flight vehicles is larger than predicted |
| the prefix drifted from crewed research aircraft to unmanned demonstrators | crewed share from 71.4 to 26.7 percent, $p$ of 0.00138 | confirmed and measured |
| non-informational purposes rise over the period | measurement share from 48.3 to 31.4 percent, $p$ of 0.204 | not established |
The two-fifths row needs a note. The first article’s two fifths was a prediction about how many articles could be written at full length, and most articles did not record their class, so the row tests the nearest quantity the ledger holds, the count of numbers given to something that flew,
\[\frac{47}{76} = 0.618, \qquad \frac{47}{65} = 0.723 \tag{44}\]of all numbers and of the numbers that went to a vehicle. Of the ten rows, seven are confirmed, one partly confirmed and one not established, and the remaining row finds more real flight vehicles than predicted. The four formal claims all hold, and a framing article is most exposed on such claims, since it wrote down its definitions before it had the data. The qualifications fall on the cause of the clustering and on purpose. The confirmation that matters most is the crewed share, because it is the one the first article called its principal historical finding and asked to be counted.
The first article also asked whether the instrument model still describes what an X designation means. The answer the ledger supports is that it describes about two fifths of the vehicles across the series, 25 of 65 classified as built to measure, and that the other three fifths were never the model’s subject. What changed, as far as the record can tell, is not the share of instruments. It is that the instrument now usually flies without a pilot, is paid for by a wider spread of agencies and laboratories, and is no longer described in the register in the government’s own words.
Where the Framing Breaks Down
The data are the series’ own readings of its sources. Every count in this article is a count over what seventy earlier articles concluded, so an error that ran through the series’ way of reading would reappear here as a result. Each value is quoted from the article that states it, which establishes that the value is what the article says. It does not establish that the article was right.
The keystone classes are one reader’s classification per article. Each article’s keystone is classified by one reader with no second classification, so there is no measure of agreement between readers. The classification that matters most, measurement against everything else, is recorded with its alternatives in each record, so the counts can be recomputed under any other coding.
The entry year of an early number is a proxy. Most articles before the X-37 do not date their designation. The two datings used here disagree by up to twenty-nine years for one number, the X-62, whose aeroplane first flew in 1992 and whose number came in 2021, and the results are reported under both. The decade boundaries are arbitrary too, and a clustering result that survived only one choice of boundary would be weak. This one survives both datings, and a finer or coarser bin was not tried, so robustness to the bin width is not claimed.
The tests are several, and each is reported at its own probability. Seven probabilities are reported, four for the crewed share, one for the purpose share and two for the clustering. The Bonferroni correction for seven tests multiplies the crewed result’s probability by seven and errs on the side of caution [Dunn 1961],
\[7 \times 0.00138 = 0.0097 < 0.01 \tag{45}\]and the result survives it, while the purpose result was not significant before any correction. No other result in this article rests on a test.
The unit is the number, and the number is not always one vehicle. The X-24A and X-24B are one number and one airframe rebuilt, the X-44 is one number and two aircraft, and the X-63 and X-64 are two numbers and one programme. Where the ledger had to choose, it took the vehicle that flew or the earliest one, and each such choice is in the record’s notes.

The survey asks what the literature says about the research aircraft as a class, and so it is not a survey of any one aircraft’s subject, each of which the seventy earlier articles surveyed in turn. It gathers the history of research aircraft and flight research, flight research as a method and its instruments, the comparison of ground facilities with flight, the demonstrator and the acquisition system that buys it, the uncrewed turn, hypersonic and space-access flight research, vertical-flight research aircraft, the institutions that sponsor the work, aerospace designation and nomenclature, the history and philosophy of engineering knowledge, and the technical-report literature the series drew on. Its 4,710 records fall in the twelve clusters above, and its sources and admission rule are set out under The Source Base.
The State of the Literature
The literature written about X-planes as a class is mostly history, and the history stops early. The standard institutional accounts describe the arrangement in which the research aircraft were built, the National Advisory Committee for Aeronautics as an institution in which technology and institution shaped each other [Roland 1984], the Langley laboratory’s organisation and its cooperation with industry and the military [Hansen 1986], and the laboratory’s partnership with the Department of Defense through the 1990s [Chambers 2000]. The flight-research histories trace the method from Cayley through the X-15 [Gorn 2001], the flight research centre where most of the series flew has histories covering it from 1946 [Hallion 1984] [Wallace 1996] and an annotated bibliography of its technical publications from 1946 to 2006 [Fisher 2007], and the NACA research airplanes have a selected history of their contributions [Hallion and Peebles 2014], the last known here from its title alone. Hallion’s history runs from the supersonic era to the space shuttle with the flight chronologies of the aircraft, and Wallace’s covers every major research aircraft and lifting body NASA studied there from the X-1 to the X-31, and the X-15 has a history that its author called a first step toward the history it lacked [Jenkins 2000] [Jenkins 2007]. The one inventory of the whole designation range in the survey stops at the X-50 and states this series’ clustering claim and its purpose claim independently, describing almost thirty designations from the late 1940s to the late 1970s, a gap, a resurgence in the late 1990s, and criticism of prototypes in the series that it answers with the X-11, X-12 and X-27 [Jenkins et al. 2003]. A later book carries the range to the X-60, and no abstract for it was retrievable, so it is cited for its title [Gorn and De Chiara 2021b].
The newest class-level literature is NASA managing the X-plane as a product, and the records of that kind in the survey date from 2015 onward. A parametric cost model running from the X-1 to the X-Wings was presented in 2015, and only its title was read here [Sterk and McAtee 2015]. NASA’s cost engineers then built an X-plane database and parametric cost model whose variables include whether the aircraft is manned or unmanned, and closed by asking for accurate and traceable cost data from historical X-plane records [Sterk et al. 2016]. A later study used historical cost and schedule data to estimate how far programmes exceed their reserves [Sterk et al. 2018], and a conceptual design process aimed at a large X-plane flying within three years of contract award for under 100 million dollars [Welstead et al. 2017]. NASA’s Office of the Chief Engineer evaluated the agency’s project and risk processes for piloted X-planes and found none fully appropriate for governing experimental aircraft [Hirshorn and Kemmerly 2018], and a workshop of more than sixty engineers, researchers and others in May 2019 gathered fifty years of X-plane practice into lessons on organisation, life cycle, flight and risk [Hirshorn et al. 2024]. The choice between a crewed and an uncrewed mid-sized X-plane appears in this literature as a subjective analysis of risk and complexity [Lechniak 2017]. In it the series’ crewed-share finding appears as seen from inside the agency making the choice.
Work on ground against flight is now about computation, and the residue it describes has not gone away. A NASA account of the X-36, X-45A and X-48B describes computation and wind tunnels complementing, calibrating and verifying one another before flight [Cosentino 2007a]. Tunnel data at Reynolds numbers an order of magnitude below flight still have to be extrapolated, and a 2024 method fixes the extrapolation exponents from two subscale tests [Traub 2024]. The X-56A’s flutter was over-predicted by every method in a workshop of six [Ouellette et al. 2026]. System identification from flight data has become routine enough to be reviewed by institution, with NASA Langley’s review naming X-planes and subscale demonstrators among its examples [Grauer n.d.-a].
The acquisition literature recommends prototyping and has not settled how to do it well. A RAND synthesis of thirty years of acquisition research recommended austere prototyping and found programme outcomes improving over time [Improving the Military Acquisition 1986], and a 2014 study found that prototyping still lacked a knowledge-based approach [Coble et al. 2014]. Cost growth on aircraft work-breakdown elements is fitted best by lognormal or Weibull distributions whose upper percentiles budgets underestimate [Marquiz et al. 2025]. A supersonic demonstrator outside the designation, the XB-1, has a published account of its development and flight testing, cited here for its title [Veletas 2026].
Writing on uncrewed aircraft has moved from whether to fly without a pilot to how many uncrewed aircraft one pilot can direct. Work on manned and unmanned teaming proposes an operator capacity model relating the number of unmanned systems to communication latency and machine support [Korecki and Hoika 2026], and an Australian account describes the move from remotely piloted aircraft to autonomous collaborative platforms in terms of affordable mass [Australian Defence Force and Joyce 2026]. The X-62 was redesignated to serve that question, an autonomy question asked of an aeroplane with a pilot aboard [X-62].
In vertical flight the series’ newest aircraft and its oldest unsolved problems meet. A 2026 computational study calls the conversion between hover and cruise one of the most complex and hazardous aspects of tiltrotor operation [Sridhar and Smith 2026]. A wind-tunnel testbed is still measuring whirl flutter across rotor speed, pitch-flap coupling and stiffness to give analysis its validation data [Thornburgh et al. 2025], and a dynamically scaled swept-tip proprotor tested to 200 knots found its comprehensive analysis predicting the stability trends in general and not the torsion mode [Delgado et al. 2026]. Those are the limits the X-76 was configured to avoid by stopping its rotor [X-76]. NASA’s newest vertical-flight research aircraft was presented in 2026 under the name RAVEN, for Research Aircraft for eVTOL Enabling techNologies, an electric vertical take-off and landing aircraft, rather than an X number [Whiteside and Welstead 2026].
Most of what is written about the institutions is written by the institutions themselves. NASA’s overview of its sustainable aviation work in 2021 describes the coming changes as the most substantial since jet engines and swept wings converged more than sixty years earlier [Kenyon et al. 2021], and the X-66 was designated to serve that programme [X-66]. The National Research Council’s assessments of NASA aeronautics of 2006, 2008 and 2012 are cited for their titles, the last being titled as the recapture of NASA’s aeronautics flight research capabilities [Decadal Survey of Civil 2006] [NASA Aeronautics Research 2008] [Recapturing NASA’s Aeronautics Flight 2012]. NASA’s technical histories of single subjects also take a longitudinal view, Loftin’s of the evolution of the subsonic aeroplane’s configuration [Loftin 1985] and Henderson and Huff’s of jet noise research from the early 1950s, which ends with noise for supersonic commercial aircraft still an area of NASA’s research [Henderson and Huff 2021].
Hypersonic research still describes flight as the final test. NASA’s account of its hypersonic X-plane family of 1997 called in-flight experimentation the ultimate crucible for proving technology readiness [Hicks and Trippensee 1997], and DARPA’s experimental spaceplane programme has a published account of its findings whose title alone was consulted here [Wierzbanowski and Ramasubramanian 2020].
One silence is measured, and it concerns this series’ subject. The designation and nomenclature cluster holds 3 records. Annual tables titled Designations of Aircraft in a military reference work are parts of that work rather than separate works and are not counted, and of the 3 the one analytical record is a history of military naming in another country, which finds naming policy always susceptible to the political climate [Cowling 2012]. No title among the survey’s 4,710 records names the United States research designation sequence as its subject, and none names its crewed share, its skips or its ordering. The first article predicted that silence, and the survey measures it. Outside the survey it is broken chiefly by the specialist register this series used throughout [Parsch, DOD 4120.15-L Addendum].
And the technical-report literature has a history that explains part of the series’ source gradient. The National Aeronautics and Space Act of 1958 directs the agency to provide for the widest practicable and appropriate dissemination of information concerning its activities and the results thereof [NASA Communications 1958], and the reports server was built in the 1990s to meet that requirement [Nelson et al. 1995], and its later fate was the subject of a 2014 paper known here by its title [Takahashi 2014]. Dryden’s annotated bibliography lists nearly 2,900 unclassified technical reports and papers from September 1946 to December 2006, running from the X-1 and the early X-airplanes through the X-15, X-29, X-31 and X-43 [Fisher 2007]. The series’ early articles stood on that documentary base. A source base that thins after 2000 is partly a change in what is published as a report, as the first article argued when it observed that later programmes generate press releases, fact sheets and conference papers rather than technical reports.
Research aircraft and their history
The designation range itself, from the X-1 to the newest numbers, together with the research aircraft outside it that flew alongside, the lifting bodies, and the inventories and histories that treat research aircraft as a class.

The Source Base
This article’s primary sources are the seventy articles that precede it. Each is read for a fixed set of facts, and each fact is taken from the article that states it, with its quotation. The 21 coding decisions made on top of the ledger carry quotations too. The register of allocations is the compilation Andreas Parsch publishes from data the Department of Defense has released, read in full as the 539 rows of the copy he last updated on 23 August 2026, with its officiality markup read at all three levels and its notes read for the sources of out-of-sequence numbers [Parsch, DOD 4120.15-L Addendum]. Every register count in this article is taken from all 539 rows of that copy, with no cut-off at this article’s date, so the X-68A and X-76A rows are counted although neither was public on that date. The register lists designators allocated after 19 August 1998, the date of the official list of that year [DOD 4120.15-L, 1998], and the 2004 edition of the official list was read for whether it dates its research rows, which it does not [DOD 4120.15-L, 2004]. The compiler’s appendix of unmanned military X vehicles was read as a second source on crew [Parsch, Directory of U.S. Military Rockets and Missiles, Appendix 4], and his page of missing designations and his account of the allocation process as primaries on the anomalies and the procedure [Missing USAF and DOD Aircraft Designations] [Allocation of Official Aerospace Vehicle MDS Designations]. Eleven original papers of the statistical methods the article uses were read for their definitions, Kendall, Wilson, Fisher on the exact test, on contingency tables and on the Poisson dispersion test, Cochran, Woolf, Shannon, Pielou, Dunn and Fleiss with his colleagues. Six editions of the numbering rule, of 1962, 1994, 1997, 2005, 2014 and 2020, were read by earlier articles [X-67]. Four of them are cited here directly as well as through those articles [Air Force Regulation 66-11, 1962] [Air Force Joint Instruction 16-401, 1994] [Air Force Instruction 16-401, 2005] [Department of the Air Force Instruction 16-401, 2020], and the issues of 1997 and 2014 are cited through the X-67 article that read them, the issue of 2014 being the first to refuse skipped sequences.
The copy is later than this article’s date, and the register then current was smaller. The version current on 16 December 2025 was the compiler’s update of 11 August 2025, as archived on 10 December 2025 [Parsch, DOD 4120.15-L Addendum, as archived on 10 December 2025]. It held 526 rows and 29 research rows, of which 21 were official, 6 carried the compiler’s description cell, 2 were absent from released data and none was partly marked, and 11 of the research rows described an uncrewed vehicle. It held neither the X-68A row nor the X-76A row, so on this article’s date the public register showed the research series ending at the X-66A, with no passed 67 and no passed block from 69 to 75. Under that version the ordering test covers 21 numbers, whose 210 pairs are 207 concordant, 1 discordant and 2 tied, for a rank correlation of 0.981, and 16 of its 20 advances equal one, the others being the skips at the X-50A, X-53A and X-59A and the backfill at the X-49A, so the numbers it shows permanently skipped are the 52 and the 58. It held 66 Q rows, 8 of them out of sequence, without the YFQ-48A, and of the founding-year numbers only the YMV-75A and the F-47, then dated to March 2025. The single discordant pair, the recorded cause of every skip and the boundary of official wording at the X-60A are the same in both versions. The two later research rows first appeared between 15 January and 1 February 2026, as The Register Stopped Being the Government’s Voice sets out, and every statement here about the X-68A, the X-76A, the passing of 67 and of the block, the 539 rows, the 31 research rows and the 69 Q rows describes the later copy.
The research survey holds 4,710 records drawn from the Crossref bibliographic index and NASA’s Technical Reports Server, of which 46 are hand-chosen sources read for their abstracts and 4,664 are admitted on their titles. Of the records, 1,713 are report primaries, being 36.4 percent, by the identifier rule set out under The Definition of Primary. The median publication year is 1999, and the dated records run from 1918 to 2026.
The Definition of Primary
Primacy is a property of the document, and this survey derives it from the identifier. A record is a report primary when its address is on NASA’s Technical Reports Server or it carries a digital object identifier under the 10.21236 prefix, which Crossref registers for Defense Technical Information Center reports. Of the 1,713 report primaries, 1,518 are reports-server records and 195 are Defense Technical Information Center reports. The rule does not reach the journal and conference papers that report flight tests and analyses at first hand, so 36.4 percent is a lower bound on how much of the survey is first-hand. The 46 hand-chosen sources are a different selection, being records chosen by hand and read for their abstracts as well as their titles.
Thin Subjects
Four subjects that this article’s argument depends on have thin literatures. Each count below is the number of research records in this survey whose title carries at least one of the listed terms, with a hyphen or a slash read as a space. Where a row joins two groups of terms with the word together, a title must carry a term from each group.
| Subject | Title terms counted | Records |
|---|---|---|
| the designation and naming of aerospace vehicles | designation, designations, designator, designators, nomenclature, naming together with aircraft, aerospace, military, missile, missiles, vehicle, vehicles, rocket, rockets | 3 |
| the crew of a research aircraft | manned, unmanned, crewed, uncrewed, piloted, optionally piloted together with x plane, x planes, research aircraft, research airplane, research airplanes, research vehicle, research vehicles, experimental aircraft | 25 |
| the cost of research aircraft | cost, costs together with x plane, x planes, x 1, research aircraft, research airplane, research airplanes, experimental aircraft | 4 |
| the research aircraft as a class | inventory, history, histories, lessons learned, decade together with x plane, x planes, x vehicles, research aircraft, research airplane, research airplanes | 8 |
The designation is almost absent from its own literature. The 3 titles are the designation and nomenclature cluster discussed above, and none of them names the United States research designation sequence.
The crew of a research aircraft appears in the literature as a vehicle type rather than as a question. Of the 25 titles, one compares a crewed with an uncrewed X-plane [Lechniak 2017], 22 others name a remotely piloted or unmanned research vehicle as the vehicle under study, and the remaining 2 concern piloted vehicles. The crewed-share result above therefore rests on the series’ own record of its vehicles rather than on a published analysis.
The cost of research aircraft has a literature only from 2015. The 4 titles date from 2015 to 2018, and all of them are reports-server records.
The research aircraft as a class has one inventory. Of the 8 titles, 2 are editions of one inventory of the X designations, the later stopping at the X-50 [Jenkins et al. 2003], and the other 6 concern single aircraft, a decade of X-vehicles or the structures of X-planes.
What the Survey Admits
A record is admitted only when a person reading its title finds it on this article’s subject, which is research aircraft as a class and the institutions and methods around them. The 46 hand-chosen sources are read for their abstracts as well. Two records with the same title, from the same authors and the same kind of source within two years, are one document deposited twice, and only one of them is kept.
Reviews of books, reference and definition entries and notices are not admitted, and a document deposited twice is admitted once. An authored encyclopedia article of more than two pages and a chapter of a textbook are research works and are kept, and a glossary of acronyms and terms is a set of definition entries and is not.
The excluded classes show where the vocabulary of designation and flight research collides with other fields. Designation and nomenclature systems for alloys, refrigerants, animals, chemicals and genes are excluded, as are X-ray sources such as Cygnus X-1 that are named in the form of a designation. Studies of the Edwards Air Force Base site rather than of the flight research done there are excluded, among them its groundwater, subsidence, seismicity, flora, archaeology and environmental assessments, and so is a biography of an air marshal who shares the base’s name. Reports admitted on the name of DARPA, the Air Force Research Laboratory, NASA or NACA whose work lies outside aerospace are excluded, among them work in natural language understanding, omics, network security, optics, astrobiology and ozone science and a genetics record on an allele named NACA, and so are technology demonstrators outside aerospace, such as unexploded ordnance clearance, road vehicles and command information systems. Experiments flown in space rather than through the atmosphere are excluded, among them heat pipes, spacecraft structures, thermal control, electric propulsion and satellites, and so are flight experiments in biology and materials science, the flight of birds and insects, and the ballistics of gun-launched ordnance. The phrase research aircraft is excluded where it names a platform for another science, such as an atmospheric or earth-science aircraft, because the X-planes research flight itself. Applications of uncrewed aircraft in other fields, such as forestry, surveying, mapping and environmental measurement, are excluded, and so are control-theory papers that use the planar vertical take-off aircraft as a benchmark model and prototyping in the sense of a tool for building components, software or simulation models. A laboratory’s component products, such as cryocoolers, lasers and solar cells, are excluded as a judgement of scope, since neither the article’s subject nor the cluster of sponsoring institutions, which holds the institutions and their research policy, extends to them. Correction, erratum and withdrawal notices, figures, tables and supplementary files of other works, subject indexes, and peer-review reports and decision letters are excluded because they are not works.
Doubtful records are kept where their subject is propulsion tied to a flight vehicle, experiments carried on launch vehicles, the civil operations of uncrewed aircraft, ground equipment for aircraft, or the sponsoring institutions’ own outreach and status records, since those subjects lie within the survey’s clusters on space access, flight research, the uncrewed turn, demonstrators and the sponsoring institutions. A few terse report titles whose subject the title does not settle are kept on the same terms.
Every research title has been read for relevance, so the off-topic share that remains is a matter of reading judgement. A reading of titles cannot show that a work is relevant in substance, so this is a statement about titles only.
Epistemic State
The Article’s Own Vantage Point
The article is dated 16 December 2025, and several of the facts it uses postdate that date. The X-68A and X-76A rows first appeared in the public register between 15 January and 1 February 2026 [X-76], DARPA announced the X-76 on 9 March 2026, and the reason for the number 76 is known only from that announcement. The register itself is read in its copy of 23 August 2026, and the counts of the version current on this article’s date are stated under The Source Base where they differ [Parsch, DOD 4120.15-L Addendum, as archived on 10 December 2025]. Every statement about the X-68A, the skipped 67 and the block from 69 to 75 rests on that later copy, as the X-67, X-68 and X-69 through X-75 articles said for themselves. Every statement about the X-76’s number, and the founding-year class it completes, rests on documents published after this article’s date, as the X-76 and X-69 through X-75 articles said for themselves. The survey also reaches past the date, its latest works being of 2026, among them the vertical-flight studies, NASA’s presentation of RAVEN of May 2026 and the X-56A flutter workshop paper, which the review discusses as current literature for a reader of 2026 rather than as knowledge available on 16 December 2025.
Historical Fact
The allocation dates, designations, contractors and sponsors of the register’s rows, the register’s notes on the X-50A, XQ-58A, XQ-67A and the other out-of-sequence drone numbers, and DARPA’s statement of why it chose 76 are historical facts from primary documents. The facts about individual aircraft are the earlier articles’ and carry those articles’ sources.
Measured From the Ledger and the Register
The counts of outcomes, design crews, keystone classes, ground-comparison verdicts and reasons for not flying are measurements over the ledger. The relation’s totality, its two failures to be a function and its four failures of injectivity are measurements over the ledger and the register. The rank correlation, the pointer walk and the officiality split are measurements over the register. Each can be recomputed from the register and the earlier articles, and none depends on a judgement made after the counting.
Statistical Analysis
The index of dispersion and its chi-square test, the Wilson intervals, Fisher’s exact tests and the entropy of sponsorship are standard methods applied to the counts. Their assumptions are stated where they are used, the dispersion test assuming independent decades under a constant rate, and Fisher’s test conditioning on the table’s margins.
Classification, Stated as Such
The keystone class of each vehicle and the reason a vehicle did not fly are classifications made by one reader per article, and the purpose result rests on them. The crewed result depends on the articles’ statements and on a rule that a missile or rocket carries nobody, and it survives the most adverse assignment of the six vehicles whose crew is not stated.
Inference
That the clusters are institutional rather than budgetary is an inference from the coincidence of the second cluster with new sponsors, and no budget series was tested against the allocation dates. That a number announced as a message is a different object from a sequence index is an interpretation, and the evidence for it is the change in how the reason was published, from a compiler’s note in 2002 to a headline in 2026.
What the Record Does Not Settle
Who chose the numbers is known for three of them, the X-50, whose number was requested by DARPA or by Boeing depending on the account, the F-47, whose choice released Air Force public affairs correspondence attributes to General Allvin [X-69 through X-75], and the X-76, whose number DARPA announced. For the rest the record identifies the allocating office and not who asked for it. Whether the share of vehicles built to measure has fallen cannot be settled at the size of this series. A difference of the size observed would need about 131 vehicles in each period to be detected four times in five at the 5 percent level, against the 29 and 35 the series has.
Out of Scope
This article does not revisit any aircraft’s engineering, which the seventy articles before it did, and it does not resolve any question those articles left open. It does not survey the literature of any one aircraft’s subject. It does not treat the pre-1946 designation systems, foreign research aircraft, or the research aircraft that carried NASA rather than military designations, as the first article excluded them. It does not test the clusters against budget data, which would need a budget series the series never assembled. It does not make a documentary-trace count by designation, and a reader who wants that measurement will need to curate title matches by hand rather than by query.
Conclusion
The X designation began as a count of instruments, and it still mostly is one. Sixty-five of its seventy-six numbers went to a vehicle, the numbers the register can test kept their order in every case but one, and no fall in the share of vehicles built to measure something can be detected in the record. The first article’s model of the research aircraft as an instrument describes about two fifths of the X vehicles across the whole series, and the record cannot show that it describes fewer of them now than it did in the 1950s.
What changed is who is aboard, who pays, who can read the description, and how the number is chosen. Of the X vehicles whose crew is recorded, seven in ten carried a pilot before 1990, and nearly every aircraft among them did, and since 1990 just over one in four has. The sponsors went from the Air Force and NACA to a spread of agencies and laboratories. The register stopped carrying the official description of each research aircraft after the X-60. And the number went from being assigned to being chosen, first quietly in 2002 for a pun on fifty-fifty, then openly for 1776, allocated in 2025 and announced in March 2026 by an agency presenting its choice as the news.
The series ends at a test the X-69 through X-75 article set [X-69 through X-75]. The next research designation is the X-69A if the X-49 precedent governs, since a passed number was assigned to the next request in 2003, and the X-77A if the rule of 2014 and 2020 governs, since it defines the next number from the last approved one [X-67]. Whichever it is will show whether the X-76 was a skip or a new ceiling, and so whether the designation is still a count with a celebration in it, or has become a sequence of chosen symbols. Seventy-one articles ago this series opened by saying that a research aircraft is a machine built to measure one thing. The designation that marks it turned out to measure something too, the institutions that kept it.
Equations
This section collects the 45 display equations of the article in the order they appear, each under its number and reproduced exactly as it stands in the text. A title in bold names an established result, and a title in italics beginning with the word Bespoke names a construction made for this analysis. Of the 45, 30 are established and 15 are bespoke. Every quantity here is a count, a share, a probability, a number of bits or an interval in days, the entry year of an early number is a proxy dated two ways that the article calls P1 and P2, and several classifications, among them the keystone class and the comparison verdict, are one reader’s readings of each article rather than measurements.
Equation 1, Bespoke Assignment Relation Between Numbers and Programmes. Following the first article, the synthesis writes the designation system as a relation between the design numbers 1 to 76 and the set of programmes, with no assumption that it is a function. X-Planes series
\[R \subseteq D \times P, \qquad D = \{1, 2, \dots, 76\} \tag{1}\]Equation 2, Condition for the Relation to Be a Function. The relation is a function on its domain only if no design number is applied to two different programmes.
\[(n, p) \in R \ \wedge \ (n, p') \in R \ \Rightarrow \ p = p' \tag{2}\]Equation 3, Condition for the Relation to Be Injective. The relation is injective only if no programme holds two different design numbers.
\[(n, p) \in R \ \wedge \ (n', p) \in R \ \Rightarrow \ n = n' \tag{3}\]Equation 4, Bespoke Share of Numbers Assigned to a Programme. Counting the X-23 as assigned because a vehicle flew under it, although no allocation request for it is recorded, 65 of the 76 design numbers went to a programme, a share of 0.855. Missing USAF and DOD Aircraft Designations
\[\eta = \frac{\left| \{ n \in D : \exists p, \ (n, p) \in R \} \right|}{|D|} = \frac{65}{76} = 0.855 \tag{4}\]Equation 5, Bespoke Decomposition of the Unassigned Numbers. The series divides the eleven unassigned numbers into one reserved, one refused, two taken into the drone pool and seven passed over in the block. X-39 X-52 X-69 through X-75
\[|U| = |U_{\text{reserved}}| + |U_{\text{refused}}| + |U_{\text{pool}}| + |U_{\text{block}}| = 1 + 1 + 2 + 7 = 11 \tag{5}\]Equation 6, Bespoke Share With the X-23 Counted as Unassigned. Counting the X-23 as unassigned instead, because no allocation request for it is recorded, lowers the share to 64 of 76. X-23
\[\eta' = \frac{64}{76} = 0.842 \tag{6}\]Equation 7, Monotonicity of Allocation. The assignment is monotone if a higher design number is never allocated before a lower one.
\[n < n' \ \Rightarrow \ t(n) \le t(n') \tag{7}\]Equation 8, Kendall Rank Correlation. Kendall’s rank correlation is the count of concordant pairs less the count of discordant pairs, divided by the number of pairs. Kendall 1938
\[\tau = \frac{C - Q}{\binom{m}{2}} \tag{8}\]Equation 9, Rank Correlation of Number and Allocation Date. Over the 23 research numbers whose first allocation the register records, 250 of the 253 pairs are concordant and one is discordant, which gives a rank correlation of 0.984.

\[\tau = \frac{250 - 1}{253} = 0.984 \tag{9}\]Equation 10, Accounting Identity for the Pairs. Every pair is concordant, discordant or tied on date, so the three counts sum to the 253 pairs.
\[C + Q + T = \binom{m}{2}, \qquad 250 + 1 + 2 = 253 \tag{10}\]Equation 11, Bespoke Advance Over the High-Water Mark. The article defines the advance of an allocation as its design number less the highest number allocated before it, so a counter would give an advance of one every time. X-67
\[a_k = n_k - h_k, \qquad h_k = \max_{j < k} n_j \tag{11}\]Equation 12, Bespoke Share of Advances Equal to One. Sixteen of the register’s 22 research advances equal one, a share of 0.727, the figure the X-67 article measured. X-67
\[s_1 = \frac{\left| \{ k : a_k = 1 \} \right|}{K} = \frac{16}{22} = 0.727 \tag{12}\]Equation 13, Bespoke Telescoping of the Positive Advances. Because the high-water mark moves only on a positive advance, the positive parts of the advances sum to the span of the walk from 44 to 76.
\[\sum_{k=1}^{K} \max(a_k, 0) = h_{\text{last}} - h_{\text{first}} = 76 - 44 = 32 \tag{13}\]Equation 14, Bespoke Count of Permanently Skipped Numbers. The numbers passed over by advances greater than one, less the one later backfilled, give ten permanently skipped numbers, which agrees with a direct count of the gaps between 44 and 76. Parsch, DOD 4120.15-L Addendum
\[\sum_{k=1}^{K} \max(a_k - 1, 0) - B = 11 - 1 = 10 \tag{14}\]Equation 15, Index of Dispersion. The index of dispersion is the sample variance of the counts per decade divided by their mean, which is one in expectation for a Poisson process. Fisher, The Significance of Deviations from Expectation in a Poisson Series, 1950 Cochran 1954
\[\mathcal{D} = \frac{S^2}{\bar{x}}, \qquad \bar{x} = \frac{1}{J} \sum_{j=1}^{J} x_j, \qquad S^2 = \frac{1}{J - 1} \sum_{j=1}^{J} \left( x_j - \bar{x} \right)^2 \tag{15}\]Equation 16, Dispersion Test Statistic. Under the null hypothesis of a constant rate, the number of decades less one times the index of dispersion follows a chi-square distribution with that many degrees of freedom. Fisher, The Significance of Deviations from Expectation in a Poisson Series, 1950 Cochran 1954
\[\chi^2 = (J - 1)\,\mathcal{D} \tag{16}\]Equation 17, Bespoke Dispersion of Entries Under the P2 Dating. Under the P2 dating, which prefers the register’s allocation date and then the article’s designation date, the decade counts give an index of 3.60 and a statistic of 28.8 on eight degrees of freedom.
\[\mathcal{D}_{P2} = \frac{25.61}{7.11} = 3.60, \qquad \chi^2 = 8 \times 3.60 = 28.8 \tag{17}\]Equation 18, Bespoke Dispersion of Entries Under the P1 Dating. Under the P1 dating, which takes the earliest recorded event, the decade counts give an index of 2.90 and a statistic of 23.2.
\[\mathcal{D}_{P1} = \frac{20.61}{7.11} = 2.90, \qquad \chi^2 = 8 \times 2.90 = 23.2 \tag{18}\]Equation 19, Chi-Square Tail for Eight Degrees of Freedom. For an even number of degrees of freedom the chi-square upper tail has a closed form as an exponential times a finite Poisson sum.
\[\Pr\left(\chi^2_{8} > x\right) = e^{-x/2} \sum_{i=0}^{3} \frac{(x/2)^i}{i!} \tag{19}\]Equation 20, Shannon Entropy of the Sponsor Mentions. The diversity of sponsorship in a decade is the Shannon entropy of the shares of its sponsor mentions across the sponsor classes. Shannon 1948
\[H = - \sum_{i} q_i \log_2 q_i \tag{20}\]Equation 21, Sponsor Entropy of the 1950s. The 1950s’ 26 sponsor mentions, 16 Air Force, 6 for the National Advisory Committee for Aeronautics and 4 Navy, have an entropy of 1.33 bits.
\[H_{1950s} = - \left( \tfrac{16}{26} \log_2 \tfrac{16}{26} + \tfrac{6}{26} \log_2 \tfrac{6}{26} + \tfrac{4}{26} \log_2 \tfrac{4}{26} \right) = 1.33 \ \text{bits} \tag{21}\]Equation 22, Pielou Evenness. The evenness is the entropy divided by its maximum for the number of classes present, which separates balance from the number of classes. Pielou, The Measurement of Diversity in Different Types of Biological Collections, 1966
\[J' = \frac{H}{\log_2 r} \tag{22}\]Equation 23, Wilson Score Interval. The Wilson interval for an observed proportion, which behaves well at small samples and near zero or one, is centred on an adjusted proportion with a half-width from the normal quantile. Wilson 1927
\[\frac{\hat{\pi} + \dfrac{z^2}{2N} \pm z \sqrt{\dfrac{\hat{\pi}(1 - \hat{\pi})}{N} + \dfrac{z^2}{4N^2}}}{1 + \dfrac{z^2}{N}} \tag{23}\]Equation 24, Hypergeometric Probability of a Two-by-Two Table. With the margins fixed, the probability of exactly $a$ crewed vehicles in the early group is hypergeometric. Fisher 1935
\[\Pr(a) = \frac{\dbinom{a + b}{a} \dbinom{c + d}{c}}{\dbinom{N}{a + c}} \tag{24}\]Equation 25, Two-Sided Fisher Exact Probability. Summing the probabilities of every table no more probable than the observed one gives Fisher’s two-sided probability, 0.00138 for the crewed shares. Fisher 1935
\[p = \sum_{x \,:\, \Pr(x) \le \Pr(a)} \Pr(x) \tag{25}\]Equation 26, Difference in Crewed Shares. The crewed share fell from 0.714 before 1990 to 0.267 from 1990, a difference of 0.448.
\[\hat{\pi}_{\text{early}} - \hat{\pi}_{\text{late}} = 0.714 - 0.267 = 0.448 \tag{26}\]Equation 27, Odds Ratio of a Crewed Vehicle. The odds of a crewed vehicle before 1990 divided by the odds after is 6.88.
\[\psi = \frac{a d}{b c} = \frac{20 \times 22}{8 \times 8} = 6.88 \tag{27}\]Equation 28, Woolf Interval for the Odds Ratio. Woolf’s method on the logarithmic scale gives a 95 percent interval of 2.17 to 21.8 for the odds ratio, which excludes one. Woolf 1955
\[\exp\left( \ln \psi \pm 1.96 \sqrt{\tfrac{1}{a} + \tfrac{1}{b} + \tfrac{1}{c} + \tfrac{1}{d}} \right) = 2.17 \ \text{to} \ 21.8 \tag{28}\]Equation 29, Odds Ratio Among Aircraft Alone. Among aircraft alone, 18 of 19 before 1990 and 8 of 22 from 1990 carried a pilot, an odds ratio of 31.5.
\[\psi_{\text{aircraft}} = \frac{18 \times 14}{1 \times 8} = 31.5 \tag{29}\]Equation 30, Bespoke Share of Numbers Classified as Measurement. Under the article’s one-reader classification of each keystone, 25 of the 65 vehicle numbers are classified as measurement, a share of 0.385.
\[\hat{\pi}_{\text{measure}} = \frac{25}{65} = 0.385, \qquad \text{95 percent interval } 0.276 \text{ to } 0.506 \tag{30}\]Equation 31, Sample Size to Detect a Difference in Proportions. The normal approximation for two independent proportions gives the sample per period needed for a two-sided test at the 5 percent level to detect a difference four times in five. Fleiss et al. 1980
\[N^{*} = \frac{\left( z_{0.975} \sqrt{2 \bar{\pi} (1 - \bar{\pi})} + z_{0.80} \sqrt{\hat{\pi}_1 (1 - \hat{\pi}_1) + \hat{\pi}_2 (1 - \hat{\pi}_2)} \right)^2}{\left( \hat{\pi}_1 - \hat{\pi}_2 \right)^2} \tag{31}\]Equation 32, Bespoke Measurement Shares Entering the Sample Size. The measurement shares of 0.483 before 1990 and 0.314 from 1990, both from the article’s one-reader classification, and their mean of 0.399 give a required sample of 131 per period.
\[\hat{\pi}_1 = 0.483, \qquad \hat{\pi}_2 = 0.314, \qquad \bar{\pi} = 0.399 \tag{32}\]Equation 33, Share of Vehicles Whose Programmes Ended Unflown. Fifteen of the 65 vehicle numbers belong to programmes that ended without a flight, a share of 0.231, once the three programmes still running are set aside.
\[\hat{\pi}_{\text{ended unflown}} = \frac{15}{65} = 0.231, \qquad \text{95 percent interval } 0.145 \text{ to } 0.346 \tag{33}\]Equation 34, Interval From First Flight to Designation. The interval is the designation date less the first flight date, so a positive value means the aeroplane flew first.
\[\Delta t = t_{\text{designation}} - t_{\text{first flight}} \tag{34}\]Equation 35, Share of Vehicles Designated After First Flight. Six of the 22 flown vehicles whose articles date both events were designated after their first flight, a share of 0.273.
\[\hat{\pi}_{\Delta t > 0} = \frac{6}{22} = 0.273, \qquad \text{95 percent interval } 0.132 \text{ to } 0.482 \tag{35}\]Equation 36, Intervals the Record Dates to the Day. The X-28, X-55 and X-62 were designated 349, 139 and 10,658 days after first flight. X-62
\[\Delta t_{\text{X-28}} = 349, \qquad \Delta t_{\text{X-55}} = 139, \qquad \Delta t_{\text{X-62}} = 10658 \ \text{days} \tag{36}\]Equation 37, Bespoke Share of Mixed Verdicts. Under the article’s reading of each comparison of ground prediction with flight, 23 of the 29 comparisons that reached flight data are mixed, a share of 0.793.
\[\hat{\pi}_{\text{mixed}} = \frac{23}{29} = 0.793, \qquad \text{95 percent interval } 0.616 \text{ to } 0.902 \tag{37}\]Equation 38, Information Gain as Entropy Reduction. For a quantity with Gaussian uncertainty the information gained is half the base-two logarithm of the ratio of prior to posterior variance. X-Planes series
\[I = \frac{1}{2} \log_2 \frac{\sigma_0^2}{\sigma_n^2} \tag{38}\]Equation 39, Bespoke Information Returned in the X-1 Example. The first article’s illustrative variance ratio of 400 returns 4.32 bits on one number. X-Planes series
\[I_{\text{X-1}} = \frac{1}{2} \log_2 400 = 4.32 \ \text{bits} \tag{39}\]Equation 40, Share of Drone Rows Out of Sequence. Nine of the register’s 69 Q rows carry a design number out of the Q sequence, a share of 0.130. Parsch, DOD 4120.15-L Addendum
\[\frac{9}{69} = 0.130 \tag{40}\]Equation 41, Span of the Founding-Year Class. The YMV-75A and the X-76A, the first and last of the three founding-year numbers, were allocated 329 days apart. X-69 through X-75
\[t(\text{X-76A}) - t(\text{YMV-75A}) = 329 \ \text{days} \tag{41}\]Equation 42, Bespoke Officiality Counts of the Research Rows. The article’s four officiality states divide the 31 research rows into 21 official, 7 with the compiler’s description, 2 absent from released data and 1 partly marked, so 0.677 carry the government’s wording throughout. Parsch, DOD 4120.15-L Addendum
\[21 + 7 + 2 + 1 = 31, \qquad \frac{21}{31} = 0.677 \tag{42}\]Equation 43, Bounds on the Register’s Publication Lag. The archived copies bound the interval from allocation to first public appearance at 148 to 165 days for the X-68A and 87 to 104 days for the X-76A. Parsch, DOD 4120.15-L Addendum, as archived on 15 January 2026 Parsch, DOD 4120.15-L Addendum, as archived on 1 February 2026
\[148 < \Lambda_{\text{X-68A}} \le 165, \qquad 87 < \Lambda_{\text{X-76A}} \le 104 \ \text{days} \tag{43}\]Equation 44, Share of Numbers Given to Something That Flew. Forty-seven numbers went to a vehicle that flew, 0.618 of all 76 numbers and 0.723 of the 65 that went to a vehicle.
\[\frac{47}{76} = 0.618, \qquad \frac{47}{65} = 0.723 \tag{44}\]Equation 45, Bonferroni Correction of the Crewed Result. Multiplying the crewed result’s probability by the seven tests reported gives 0.0097, which remains below 0.01. Dunn 1961
