ⓘ List of military aircraft of the United States

This list of military aircraft of the United States includes prototype, pre-production, and operational types. For aircraft in service, see the list of active United States military aircraft. Prototypes are normally prefixed with "X" and are often unnamed, while pre-production models are usually prefixed with "Y".

The United States military employs a designation and naming system to provide identifications to all aircraft types. Until 1962, the United States Army, United States Air Force formerly Army Air Force, and United States Navy all maintained separate systems. In September 1962, these were unified into a single system heavily reflecting the Air Force method. For more complete information on the workings of this system, refer to United States Department of Defense Aerospace Vehicle Designations.

This list does not include aircraft used by the U.S. military services prior to the establishment of a numerical designation system. For these aircraft, see List of military aircraft of the United States 1909–1919. It also does not include aircraft designated under the pre-1962 United States Navy designation system. For these aircraft, see List of military aircraft of the United States naval.

                                     

1. Prior to 1919

Prior to 1919, all planes flown by the Army Air Service and the Navy were referred to by the designation given to them by their manufacturer. A variety of both domestic and foreign types were operated, with the latter being the primary front-line types during the First World War.

                                     

2. Army Air Service, 1919–1924

In September 1919, the Army Air Service decided that it needed an organized designation sequence, and adopted fifteen classifications, designated by Roman numerals. Several other unnumbered designations were added later. Each designation was assigned an abbreviation, and each design a number within that abbreviation. Variants were designated by alphabetically appending letters to the design number.

In 1941, the category letter R- was allotted for "rotary wing" aircraft, and this designation was used until the founding of the United States Air Force in 1947, at which point the category letter was changed to H-, for "helicopter". However, the original numbering sequence was retained.

In 1962 when the Unified Designation System was adopted, six former Navy and Army types received new designations in the H-1 to H-6 series, which can be found here. However, the original sequence was also continued, and remains in use to the present, with the next designation available being H-73.

4. Army, 1956–1962

In 1956, the U.S. Army adopted a new, and relatively simple, designation system for its aviation assets. Aircraft were divided into three different types – A for fixed-wing aircraft, H for helicopters, or V for V/STOL aircraft, and then were given a mission modifier, which, unlike the USAF system, came after the type code: C for transports, O for observation and reconnaissance aircraft, U for utility types, and Z for experimental aircraft. Aircraft types designated in this system were numbered sequentially.

Other Designations Note: Designations YF-110, YF-112 through YF-116, and YF-118 were captured foreign aircraft used for evaluation and aggressor training. They were given designations in sequence - based on chronology - with "black" project aircraft, continuing the pre-1962 F series. Since the 50s there have been quite a few fighters developed that never entered service or never even made it past the drawing board. The were given a XF eXperimental Fighter designation sometime in their development and sometimes also a name. Some had 1 or 2 flying prototypes.

5.9. Unified System, 1962–present Helicopter

Unlike most other categories of aircraft, the introduction of the tri-service designation system in 1962 did not result in a wholesale redesignation of helicopters. While six types received new designations in the unified, "re-started" sequence, the original "H-" series of designations that started in 1948 was also continued, and no further types of rotorcraft have been designated in the "post-1962" system.

  • H-3 Sea King / "Jolly Green Giant" – Sikorsky Aircraft Formerly HSS-2
  • H-1 Iroquois / "Huey" – Bell Helicopter Formerly H-40 / HU-1
  • H-5 – Fairchild Hiller Formerly HO-5
  • H-1 Cobra / SeaCobra / SuperCobra / Viper – Bell Helicopter
  • H-6 Cayuse / Little Bird – Hughes Helicopters / McDonnell Douglas / Boeing Helicopters Formerly HO-6
  • H-2 Seasprite – Kaman Aircraft Formerly HU2K

5.12. Unified System, 1962–present Spaceplane

The only designation in the "Spaceplane" series, the MS-1A shares a designation letter with the anti-submarine warfare category, and is perhaps unique among MDS identifiers as being assigned to a future, and currently not wholly defined, concept, as opposed to a specific project.

                                     

5.13. Unified System, 1962–present Tanker

No specialised types have been acquired to receive a stand-alone K for Tanker designation; for aircraft modified for use as tankers, see the parent aircraft in the proper sequence.

                                     

5.14. Unified System, 1962–present Trainer, 1962, 1990–present

Despite the adoption of the unified Mission Designation System in 1962, only two aircraft were designated in the new series, both former Navy types. The old series continued in use until 1990, at which point a new series was started over at T-1, with the previous T-2 still being in use. However, the old series has still seen new designations being assigned. The next designation available in the T series is T-52 or T-7, depending on which series is continued.

1962 Sequence

  • T-1 SeaStar – Lockheed Corporation Formerly T2V
  • T-2 Buckeye – North American Aviation Formerly T2J
