This list of United States Navy aircraft designations (pre-1962) includes prototype, pre-production and operational type designations under the 1922 United States Navy aircraft designation system, which was used by the United States Navy, the United States Marine Corps, and the United States Coast Guard. The list also includes airships, which were designated under different systems than fixed-wing aircraft and rotorcraft until 1954, and naval aircraft that received designations under the 1911 and 1914 U.S. Navy systems, which were sequential by manufacturer and/or aircraft class, and did not convey information about the aircraft's mission.

For aircraft designations under the U.S. Army Air Force/U.S. Air Force system or the post-1962 Tri-Service system—which includes U.S. Navy, Marine Corps and Coast Guard aircraft currently in service—see List of military aircraft of the United States. For Navy, Marine Corps and Coast Guard aircraft that did not receive formal designations—including those procured from 1917 to 1922 when no designation system was in force, and later aircraft that did not receive designations for other reasons—see List of undesignated military aircraft of the United States.

Summary of pre-1962 designation systems

1911 system

The first U.S. Navy designation system, adopted in 1911, consisted of a letter signifying the manufacturer followed by sequential numbers for individual aircraft from each manufacturer. Only heavier-than-air craft (i.e. airplanes) were given designations. The system was subsequently amended to differentiate aircraft classes from the same manufacturer. The designation letters were as follows:Lua error: not enough memory.Lua error: not enough memory.

1914 system

In March 1914, the navy introduced a system similar to hull classification symbols for warships, with an alphabetical code for the aircraft class followed by a sequential number assigned to an individual aircraft. All aircraft designated under the 1911 system that were still in inventory were redesignated.Lua error: not enough memory.Lua error: not enough memory. Also consistent with warship designation practices, the designation of the first aircraft of a particular design became the type designation for similar aircraft; for instance, aircraft similar to AH-8 were referred to as AH-8 type.Lua error: not enough memory.Lua error: not enough memory.

The aircraft classes and sub-types were as follows:Lua error: not enough memory.Lua error: not enough memory.

  • A – Heavier than air
  • AH – Aeroplane, Hydro
  • AB – Flying boat
  • AX – Amphibian

This second system was abandoned in May 1917 without immediate replacement; until March 1922, the navy used manufacturers' model designations. However, some later aircraft similar to types with 1914 system designations were given conforming designations, apparently on an informal basis.Lua error: not enough memory.Lua error: not enough memory.

1922 system

Lua error: not enough memory. On 29 March 1922, a new designation system was introduced with a reorganization of U.S. naval aviation under the Bureau of Aeronautics.Lua error: not enough memory.Lua error: not enough memory. The system conveyed its information in the form:

(Mission)(Design Number)(Manufacturer)-(Subtype)(Minor Modification)

For example, F4U-1A referred to a minor modification (A) to the first major subtype (1) of Chance-Vought's (U) fourth (4) fighter (F) design.

For the first few years after the system was introduced, the manufacturer's letter and the mission letter were sometimes reversed. If it was the manufacturer's first design for that particular mission, there was no number before the manufacturer letter.

Prototypes under the 1922 system were normally prefixed with "X" (differing from purely experimental X-planes, which were not generally expected to go into production), while pre-production or trials aircraft were usually prefixed "Y", and airships were prefixed "Z" (differing from Army or Air Force use of "Z" to designate obsolete aircraft for storage or disposal).

Airships and balloons

Lua error: not enough memory. Prior to 1954, lighter-than-air craft used separate designation systems from those used for fixed-wing aircraft and rotorcraft, or were undesignated. As a general rule, a "Z" prefix identified lighter-than-air craft.Lua error: not enough memory.Lua error: not enough memory.

Rigid airships

Rigid airships were designated as ZR-class—"R" for rigid—with a suffixed number identifying the individual aircraft, and unlike all other lighter-than-air craft were commissioned no differently that surface ships; therefore, the ZR code was included as a hull classification symbol with those of surface ships. With the introduction of the Akron-class airship, an "S" mission suffix was added to signify scout (ZRS-class).Lua error: not enough memory.Lua error: not enough memory.

Other airships

The first U.S. Navy non-rigid airship was ordered in 1915 before an airship designation system was standardized and was designated DN-1[lower-alpha 2] for Dirigible, Non-rigid. When subsequent airships were ordered into series production for World War I (WWI), alphabetical class letters were adopted starting with the B-class blimp, with individual aircraft identified by a suffixed number; DN-1 was retroactively considered A-class by implication. Within each class, individual airships often had significant design variations, and were sometimes sourced from different manufacturers; the class designations referred to nominal power and size.Lua error: not enough memory.Lua error: not enough memory.

The first mission designation system for non-rigid airships, introduced in 1940,Lua error: not enough memory. took the following form:

(Construction)(Mission)-(Class)

For example, the ZNP-K referred to K-class (K) patrol (P) non-rigid airship (ZN).

In 1947, this system was replaced by one more similar to the 1922 fixed-wing system, and the "N" for non-rigid was dropped due to the termination of the rigid airship program. The 1947 system took the following form:[1]

(Z for airship)(Mission)(Design Number)(Class)-(Subtype)(Minor Modification)

For example, the ZP2N-1W referred to the airborne early warning modification (W) of the first subtype (1) of the N-class' (N) second (2) patrol (P) airship (Z).

The airship mission designations were initially "G" for scout, "N" for trainer, and "P" for patrol. In 1947, "N" was changed to "T" for trainers, while "H" for search and rescue and "U" for utility were added, although the latter two mission letters were ultimately not used.[1]Lua error: not enough memory.Lua error: not enough memory.

In 1954, the Navy did away with the separate airship designation system and unified it with the main 1922 system, while retaining the "Z" prefix.[1]

Spherical crewed free gas balloons used for airship crew training were considered ZF-class aircraft but never received formal designations and were identified only by serial number and volume; similarly, crewed kite balloons and uncrewed barrage balloons were considered ZK-class, but were undesignated.Lua error: not enough memory.Lua error: not enough memory.

Other exceptions

The non-standard XDH designation was applied to two de Havilland aircraft procured in 1927 and 1934 for use by the U.S. Naval Attaché in London.Lua error: not enough memory.Lua error: not enough memory.

In 1952, the Navy and Air Force agreed to standardize some flight training curricula and equipment.Lua error: not enough memory.Lua error: not enough memory. Accordingly, the T-28 Trojan and T-34 Mentor trainers were adopted and operated by the Navy under their Air Force designations.Lua error: not enough memory.Lua error: not enough memory.
