On August 1, 1907, the Aeronautical Division of the United States Army Signal Corps was established, and the United States Army purchased its first heavier-than-air aircraft, a Wright Model A, in 1908. It was allocated the serial number 1. Further Army aircraft were assigned serial numbers in sequence of their purchase. Unfortunately, early records from these days are rather incomplete, and there are numerous gaps and conflicts. To add to the confusion, it often happened that at the time an aircraft was rebuilt, it was assigned a brand new serial number. Some aircraft from this period (for example the DH-4 "Liberty Plane") are known to have carried at least four serial numbers during their careers. After a while, certain serial number blocks were introduced--the 200 block was reserved for seaplanes, the 40000 block for experimental aircraft, and the 94000 block for prototypes and aircraft under evaluation.
The new Army Aeronautical Division was renamed the United States Army Air Service (USAAS) on May 14, 1918. The sequential serial number scheme continued until the end of US Fiscal Year (FY) 1921 (which was June 30, 1921). At that time, the numbers had reached 69592, plus a special block of 1919-1921 experimental procurements in the 94022/94112 range.
Starting on July 1, 1921 (the beginning of FY 1922) a new serial number system was adopted based on procurement within each Fiscal Year. Each serial number now consisted of a base number corresponding to the last two digits of the FY in which money was allocated to manufacture the aircraft, and a sequence number indicating the sequential order in which the particular aircraft was ordered within that particular FY. For example, airplane 22-1 was the first aircraft ordered in FY 1922, 23-1 was the first example ordered in FY 1923, etc. This system is still in use today.
It is important to recognize that the serial number reflects the Fiscal Year in which the order for the aircraft is placed, NOT the year in which it is delivered. Nowadays, the difference between the time the order is placed and the time the aircraft is actually delivered can be as much as several years.
On July 2, 1926, the Army Air Service was renamed the United States Army Air Corps (USAAC). On June 20, 1941, the USAAC was renamed the United States Army Air Force (USAAF). On September 18, 1947, the United States Army Air Force was split off from the US Army and became a separate service, the United States Air Force. Throughout all of these changes the earlier fiscal-year serial number system remained unchanged.
In 1947, at about the same time that the USAF was officially formed, DoD regulation 5304.9003 was promulgated which required that the sequence number now have at least 3 digits. This means that fiscal year serials with individual sequence numbers less than 100 are filled up with zeroes to bring them up to 3 digits in length. So 48-1 is written as 48-001 in official documentation. Sequence numbers greater than 9999 are written with 5 digits. In 1958, the minimum number of digits in the sequence number was raised to four, so that the 1958 aircraft series started at 58-0001.
Following the passage of the Lend-Lease Act in 1941, USAAF serial numbers were allocated to US-built aircraft intended for service with Allied air forces during the Second World War. This was done strictly for administrative purposes, even though these aircraft were never intended for USAAF service. Later, during the Cold War, aircraft supplied to US allies under the Mutual Aid Program or the Mutual Defense Assistance Program were assigned USAF serial numbers for record-keeping purposes, even though they never actually served with the USAF.
Not all the aircraft which served with the US Army Air Force
were issued USAAF serial numbers.
The best-known examples are those
aircraft acquired abroad by the US Army during the
Second World War. In most cases, they
operated under their foreign designations
and serials. For example, the Spitfires acquired in the UK under
"Reverse Lend-Lease" were operated under their British designations
and their British serial numbers. In addition, some US-built aircraft that were
ordered by Britain prior to Lend-Lease but later impressed into USAAF service still
retained their Royal Air Force serials.
Occasionally, USAF aircraft are extensively remanufactured to bring them up to modern standards or to fulfill completely new roles for which they were not originally designed. In many cases, these aircraft are re-serialed with new numbers relevant to their year of re-manufacture. However, this rule is not always followed--re the rather grotesque modifications inflicted on some C-135 aircraft which did not result in new serial numbers.
The US Navy and the US Marine Corps have an entirely different serial numbering scheme, based on numerically progressive numbers allocated by the Bureau of Aeronautics. Occasionally, aircraft are transferred from the Navy to the USAF. If the transfer is anticipated to be permanent, it is usually the case that the transferred aircraft are given USAF serial numbers. Most often, the USAF serials of these transferred Navy aircraft are inserted within the regular sequence of numbers, but sometimes these new USAF serials are constructed by retroactively adding additional numbers at the end of the sequence number block for the fiscal year in which they were originally ordered by the Navy. Aircraft that are only temporarily transferred to the USAF from the Navy usually retain their Navy serial numbers even though painted in USAF markings, but it sometimes happens that aircraft loaned by the Navy are assigned brand-new USAF serials. Unfortunately, the system is not always consistent.
In recent years, the assignment of USAF serial numbers has not always been in strict numerical order within the FY. Furthermore, an aircraft is sometimes listed in a given FY block when it was actually ordered in a different FY. This is most often done for reasons of special convenience. For example, the serials of the two "Air Force One" VC-137s (62-6000 and 72-7000) might indicate that they were ordered ten years apart, whereas the actual difference was only seven years. The Presidential VC-25s were ordered in FY 1986 under the serials 86-8800 and 86-8900, but these numbers were changed to 82-8000 and 92-9000 by special order to create a series following the two earlier VC-137Cs. When some civilian aircraft have been acquired by the USAF, either by purchase or by seizure, serial numbers have sometimes been assigned out of sequence, with their numbers deliberately chosen to match their former civilian registration numbers. Other times, serial number allocation is done for reasons of secrecy, to conceal the existence of classified aircraft from prying eyes. For example, the serial numbers of the F-117s were initially assigned in strict numerical order, but they were sprinkled among several different fiscal years. In other cases, the serial numbers (e.g. the serial numbers for the new F-22 Raptor fighters) were derived from the manufacturer's construction numbers rather than from the sequence in which they were ordered. Another odd example was the A-1 Skyraiders acquired from the Navy for use in Vietnam--they had USAF serial numbers constructed by taking the plane's Navy serial number (Bureau Number) and prefixing in front of it the fiscal year number in which the plane was ordered by the Navy. For example Navy A-1E Skyraider BuNo 132890 became 52-132890 on USAF rolls.
During the 1950s and 1960s, it was common practice to include missiles and unmanned aircraft in USAF serial number batches. Consequently, it is not always possible to determine the total number of aircraft ordered by the USAF simply by looking at serial number ranges.
Following the splitoff of the USAF from the US Army, the Army continued to use the same serial number system for its aircraft, with the serials for Army and Air Force aircraft being intermixed within the same FY sequence.
Beginning in FY 1967, the Army began using serials beginning at 15000 for each FY, so Army aircraft could usually be distinguished from USAF aircraft by their high serial numbers. In addition, if an Army aircraft of helicopter had a serial number with less than 4 digits, extra zeros were added to pad the number out to 5 digits.
In FY 1971, the Army went over to a new
serial series for their helicopters, which started at 20000 and had continued consecutively
since then. Within each FY, the US Army numbers are much higher
than the USAF numbers are ever likely to get, so there is not much
danger of any overlap.
By 1914, when the Army first began to acquire tractor-engined aircraft, the official serial number began to be painted in large block figures on both sides of the fuselage or on the rudder. These numbers were so large that they could be easily seen and recognized from a considerable distance. At the time of American entry into the First World War, the large numbers were retained on the fuselage and sometimes added to the top of the white rudder stripe. By early 1918, the letters "S.C." (for "Signal Corps") were often added as a prefix to the displayed serial number. When the Army Air Service was created in May of 1918, the letters SC were replaced by "A.S". (for "Air Service"). In July of 1926, the Army Air Service was renamed the Army Air Corps, and the serial number prefix became A.C. for "Air Corps". However, these prefix letters were not part of the official serial number, and were finally dropped in 1932.
By late 1924, the fuselage serial numbers began to get smaller in size, until they standardized on four-inch figures on each side of the fuselage. In 1926, the words "U.S. Army" were often added to the fuselage number, and in 1928 the manufacturer's name and the Army designation were also added to the display, but this was not always done.
The three-line fuselage data block was reduced in size to one-inch characters in 1932 and placed on the left hand side of the fuselage near the cockpit. This is known as the Technical Data Block (TDB). The data block not only displayed the full serial number, but also the exact model type and sometimes the aircraft's home base or the branch of the military with which it served. The TDB eventually became the only place on the aircraft where the serial number was actually displayed. It was often true that the only other sort of identification shown was a unit and base identification code displayed on both sides of the fuselage or on the fin. This made it difficult to identify the actual serial number of the aircraft, leading to a lot of confusion.
The Technical Data Block is still used today, although it is now called the Aircraft Data Legend, and by the early 1990s it was reduced in size to letters only 1/2 inch high and moved to a new position near the ground refuelling receptacle. T.O 1-1-4 states that the Technical Data Block can be either on the fuselage side or near the ground refuelling receptacle.
For a few years during the late 1940s and early 1950s, the serial number displayed in the Technical Data Block often carried a suffix letter, which was not actually part of the official serial number. Five letters were used--A for US Air Force, G for US Army, N for Air National Guard, R for Air Force Reserve, and T for Reserve Officers Training Course (ROTC). For a while the letter M was used for USAF aircraft associated with American embassies in foreign countries, but this use was discontinued in August 1955.
The lack of a readily-visible serial number on Army aircraft began to be a serious problem, and on October 28, 1941, shortly after the USAAF had been formed, an order was given that numbers of no less that 4 digits would be painted on the tail fin of all Army aircraft (where feasible) in a size large enough to be seen from at least 150 yards away. This was officially called the radio call number, but was almost universally known as the tail number. Since military aircraft were at that time not expected to last more than ten years, the first digit of the fiscal year number was omitted in the tail number as was the AC prefix and the hyphen. For example, Curtiss P-40B serial number 41-5205 had the tail number 15205 painted on its tail fin, Curtiss P-40K serial number 42-11125 had the tail number 211125 painted on the fin, and P-51B 42-106559 had 2106559 painted on the tail. Since the Army (later Air Force) used the last four digits of the tail number as a radio call sign, for short serial numbers (those less than 100), the tail number was expanded out to four digits by adding zeros in front of the sequence number. For example, 41-38 would have the tail number written as 1038.
Consequently, in most situations for a World War II-era aircraft where the tail number is visible, you can deduce the serial number simply by putting a dash after the first digit, prefixing a 4, and you automatically have the serial number. Unfortunately, there were many deviations from these rules--there are examples in which only the last 4 or 5 digits were painted on the tail, which makes identification of the aircraft particularly difficult.
In the 1950s, many airplanes left over from the World War II era were still in service, exceeding their expected service lives of less than 10 years. In order to avoid potential confusion with later aircraft given the same tail number, these older aircraft had the number zero and a dash added in front of the tail number to indicate that they were over 10 years old. It was hoped that this would avoid confusion caused by duplication of tail numbers between two aircraft built over ten years apart. However, this was not always done, and it was not always possible uniquely to identify an aircraft by a knowledge of its tail number. This practice was eventually discontinued when people started referring to the number 0 as being a letter O, standing for Obsolete. The requirement for the 0- prefix was officially dropped on April 24, 1972.
For a few years during the late 1940s and early 1950s, the serial number displayed in the Technical Data Block often carried a suffix letter, which was not actually part of the official serial number. Five letters were used--A for US Air Force, G for US Army, N for Air National Guard, R for Air Force Reserve, and T for Reserve Officers Training Course (ROTC)
In 1958, a regulation was promulgated which decreed that that the tail number should be expanded to a minimum of 5 digits in length. Sometimes the tail number was cut down in length to five digits by deliberately omitting both of the fiscal year digits--for example 64-14841 would be presented on the tail as 14841. Sometime, one or more of the first digits of the sequence number would also be omitted. This practice lead to a lot of confusion.
Camouflage began to reappear on USAF aircraft during the Vietnam War, and this led to a change in tail number presentation. The letters "AF" were added directly above the last two digits of the fiscal year, followed by the last three digits of the sequence number. The three-digit sequence number has a height of the AF and fiscal year letters combined and is sometimes called the "large" component of the tail number. For example, F-4E serial number 67-0288 had the tail number 67(small) 288 (large). This could of course lead to confusion, since aircraft 67-1288, 67-2288, etc would have exactly the same tail numbers as 67-0288 under this scheme. This would not ordinary cause a whole lot of difficulty unless of course some of these larger serial numbers also happened to be F-4Es (which they were not). Unfortunately, the system was not always consistent--for example F-4D serial number 66-0234 had a tail number that looks like this: 60(small) 234(large). It appears as if this number was obtained by omitting the first digit of the fiscal, and combining the remaining "6" with the "0234". Consequently, one often has to do a lot of educated guessing in order to derive the aircraft serial number from a knowledge of its tail number, and a knowledge of the aircraft type and sometimes even the version is required. I would appreciate hearing from anyone who has noted different tail number presentations on recent USAF aircraft.
However, Air Mobility Command and USAF Europe aircraft still display the previous format for the tail number, with all digits being the same size and the first digit being the last digit of the Fiscal Year and the remaining 4 digits being the last 4 digits of the sequence number. There is no AF displayed, just the name of the command a couple of feet above it. AMC regulations state that the tail number must be the last five digits of the serial number. If the serial number does not have five significant characters at the end, the last digit of the fiscal year becomes the first character, and zeroes are used to fill up the space to make five digits. This would make 58-0001 appear as 80001. The Technical Order refers to radio call numbers on the fin, the full serial number only appearing within the Aircraft Data Legend block. In those rare cases in which the Air Force purchased more than 10,000 aircraft in a single fiscal year (1964 was such a year), aircraft with serial numbers greater than 10,000 would have both digits of the fiscal year omitted--for example the tail number of 64-14840 is 14840, not 44840. An exception was the tail number of EC-130H serial number 73-1583, which had its tail number displayed as 731583, i.e., the full serial number without the hyphen. Again, I would like to hear from anyone who has seen different types of serial number displays on Air Mobility Command aircraft.
In the years immediately following World War 2, many USAAF/USAF aircraft used markings that would make it possible to identify low-flying aircraft from the ground. This was intended to discourage the unsafe practice of pilots of high-performance aircraft making low passes (colloquially known as "buzzing") over ground points. Consequently, these numbers came to be known as buzz numbers.
The system used two letters and three numbers, painted as large as practically feasible on each side of the fuselage and on the underside of the left wing. The two letter code identified the type and model of the aircraft, and the three digits consisted of the last three numbers of the serial number. For example, all fighters were identified by the letter P (later changed to F), and the second letter identified the fighter type. For example, the buzz number code for the F-86 Sabre was FU, for the F-100 Super Sabre it was FW. The buzz number for F-100A 53-1551 was FW-551, the buzz number for F-86D 53-1020 was FU-020.
On occasion, two planes of the same type and model would have the same last three digits in their serial numbers. When this happened, the two aircraft were distinguished by adding the suffix letter A to the buzz number of the later aircraft, preceded by a dash.
Some stateside aircraft during World War II carried enlarged code numbers on their sides, but I don't know if the purpose of these large markings were to act as "buzz numbers".
The system was in wide use throughout the 1950s, but was gradually phased out during the 1960s. The January 1965 edition of Technical
Order 1-1-4 dropped all mention of any buzz number requirement, and these numbers started getting painted over and were largely
gone by the middle of 1965.
But in 1966, the Army started using five digit sequence numbers that were greater than any sequence numbers used by the USAF, so that observers would not confuse aircraft between the two services. In addition, Army sequence numbers that were allocated within the Air Force sequence were often padded with extra zeros to make them have a total of 5 digits. Unfortunately, there is some confusion, since this system was not always consistently followed, and there were numerous departures from this norm. Although the Army started using 5 digit serial numbers starting in 1964, there was a mixed bag of four and five digit numbers in actual use. For tail number presentations (or pylon numbers for helicopters), the early years were pretty consistent, using the last digit of the fiscal year and just the four digits of the serial number being shown. When the five digit serial numbers started being used, there was a mixture of tail number presentations of just the five digits with no year (and sometimes a leading zero!), as well as presentations in which the last digit of the year was shown, along with all five of the sequence numbers. Sometimes both the digits of the year number were painted over and then just the the five-digit sequence number was presented. Sometimes, Army helicopters used the last three digits of the sequence number as a call sign and you will often see those three digits painted on the nose, the side window or highlighted on the pylon itself. There are even a few older aircraft with the two digit year and the entire five digit serial number shown, just to round out all the options. (Ref, Nick Van Valkenburgh, Jul 26, 2013)
In 1971, the Army started using sequence numbers starting at 20000, and the numbers were not restarted with each succeeding fiscal year.
In written correspondence, the leading zeros were often dropped. It is not at all clear when the system of padding sequence numbers with zeros actually started. It also seems that the Army continues to use both systems for its aircraft serial numbers, one a sequence number greater than any sequence numbers used by the USAF, plus lower sequence number padded with zeros. (Ref, Nick Van Valkenburgh, Jul 26, 2013)
The ultimate end for many USAF and US Army aircraft and helicopters once they leave active service is the boneyards at the Davis-Monthan AFB near Tucson, Arizona. At the end of World War 2, the base was selected as a storage site for decommissioned military aircraft. The dry climate of Tucson and the alkali soil made it ideal for aircraft storage and preservation. Excess DoD and Coast Guard aircraft are stored there after they are removed from service. Sometimes the aircraft are actually returned to active service, either as remotely-controlled drones or are sold to friendly foreign governments, but most often they are scavenged for spare parts to keep other aircraft flying or are scrapped.
Initially known as the Military Aircraft Storage and Disposal Center (MASDC), the name of the facility was changed in October of 1985 to the Aerospace Maintenance and Regeneration Center (AMARC). AMARC was officially redesignated May 2, 2007 as the 309th Aerospace Maintenance and Regeneration Group (AMARG), but it still uses the title AMARC for worldwide recognition and legacy reasons. If I know of the date at which an aircraft was transferred to MASDC/AMARC, I list it here.
When an aircraft enters AMARG, it is assigned a code number (known as a Production Control Number, or PCN) consisting of four letters, followed by a three-digit number. The first two letters specify the service (AA for Air Force, AN for Navy, AC for Coast Guard, AX for government agency aircraft, AY for foreign allied aircraft). The second pair of letters specify the type of aircraft (e.g FP for the F-4 Phantom), and the three digit number specifies the order in which the particular plane of that type was entered into AMARG. For example, the first F-4 admitted to AMARC would be numbered AAFP001, with two zeros being added to pad out number of digits to 3. So the PCN was useful in telling at a glance who owned the aircraft, what type of aircraft it was, and the order in which it arrived at AMARG
Prior to Oct 1994 the number in the PCN code had three digits, but AMARC realised that they were soon going to have more than 1000 F-4s on inventory, and the decision was made that it was necessary to expand the number format to four digits in order to accommodate new Phantom arrivals. So RF-4C 64-1021 was given the number AAFP969 on Oct 19, 1994 and the next arrival 64-1068 was given the number AAFP0970 the same day. All later F-4s arrivals were numbered in the four-digit style. I imagine that once AMARC had altered their database field to use 6 characters, they then decided to use that style for ALL new arrivals from Oct '94, and a zero was prefixed when the order number was less than 1000. Ref: eLaReF, Jun 17, 2012.
To add to the confusion, an aircraft could receive multiple PCNs if it came back to the facility multiple times - for example - an aircraft might have come in to AMARG for service life extension (it would have been given a PCN for the duration of its refit). Then it would have been returned to the operational fleet. During its service, if the operators determine that all aircraft of this type need something else to be checked, the aircraft would return to 309 AMARG for that check as part of some minor repair work. On arrival it would have received a new (2nd) PCN. On completion of the minor repairs, the aircraft would return to the operators. Eventually when the operators determine that the aircraft is no longer needed and they retire it to storage, a third PCN would have been assigned. If it happened that the aircraft were returned to service yet again and then brought back to AMARG for storage, it would get a *fourth* PCH. (Ref: Robert D. Raine, Jun 27, 2013)
An aircraft can also be assigned a different PCN if it is administratively tranferred to a different service while it is sitting in the boneyards. For example - AMARG currently stores a C-131 that originally arrived as a Navy asset (and was assigned a Navy PCN). The Navy transferred the aircraft to the Air Force (so the Navy PCN was removed and replaced by an Air Force PCN). The USAF then transferred it to another government agency, so the USAF PCN was removed and replaced by a U.S. Gov't agency PCN beginning with the prefix "AX." Same plane, three different PCNs. (Ref: Robert D. Raine, Jun 27, 2013)
Recently, AMARG introduced a new computer system and decided to stop bothering to assign a PCN when an aircraft arrives at the facility. Everything is now tracked by serial number, since no two aircraft ever have exactly the same serial number. PCNs were not removed from older aircraft, but new PCNs are no longer assigned to aircraft when they arrive. (Ref: Robert D. Raine, Jun 27, 2013).
A list of the serial numbers of aircraft transferred to MASDC/AMARC can be found on the website at www.amarcexperience.com.
When an aircraft is constructed, the company which built it assigns it a manufacturer's serial number. This number is usually displayed on a plate mounted somewhere inside the aircraft. When the aircraft is sold to the Air Force, it is issued a military serial number by the Defense Department. These two numbers bear no relationship with each other, but they are often confused with each other. When I know the manufacturer's serial number of a particular military aircraft, I list it. If a military aircraft ultimately ends up in civilian hands, it is issued a civil registration number by the owner's national civilian aviation authority. In the USA, these numbers are issued by the FAA, and are known as N-numbers in the USA, since they all begin with the letter N. Typically, the FAA uses the aircraft's manufacturer serial number to track these aircraft. For example, a lot of C-47 Skytrain aircraft ended up in civilian hands after their military service ended, and they are tracked by using their manufacturer's serial numbers.
The following is a list of serial numbers for US Army and USAF aircraft. It is incomplete, with numerous gaps--especially in later years. If I know the final disposition of a particular aircraft, or if the aircraft has some special historical significance, this information is listed here too.
Enjoy yourself browsing through these lists--there are lots of neat historical interludes provided here. These lists are by no means complete or error-free and I would appreciate hearing from anyone who has additions or corrections.
There are a lot of people who want to know about the operational history or ultimate disposition of a particular aircraft referred to in this database, but about which I have little or no information. If you have a specific question about the history of a particular USAAF/USAF aircraft, you might try the Air Force Historical Research Agency which is located at Maxwell AFB, Alabama. They have cards on virtually every aircraft ever owned or operated by the USAAC/USAAF/USAF, and they might be able to answer your question fairly quickly. Another source of information is the Individual Aircraft Record Card file located at the National Air and Space Museum Archives Division. They also may be able to help you. However, you are always welcome to e-mail me in any case and I will see if I can dig up something.
