List of military aircraft of the United States (naval)

This list of military aircraft of the United States (naval) includes prototype, pre-production and operational types 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.

Prototypes are normally prefixed with "X" and often unnamed (note that these are not the same as the experimental X-planes, which are not generally expected to go into production), while pre-production models are usually prefixed "Y".

For aircraft designations prior to the adoption of this system, see List of military aircraft of the United States (1909–19).

For aircraft designations under the U.S. Army Air Force/U.S. Air Force USAF system or the post-1962 Tri-Service system and aircraft currently in service, see List of military aircraft of the United States.

This series of four airships (two one-offs and two production Akron-class vessels) were the only airships in American history to be commissioned as ships of the United States Navy. ZR-2 is missing from the list as that airship (the British R-38) crashed and was destroyed before delivery.

In 1946, the "S for Scout" designation was replaced by "S for anti-Submarine", however, the numbers in the 'S' series were not restarted.
