This list of military aircraft of the United States includes prototype, pre-production and operational types. For aircraft currently in service, see the List of active United States military aircraft. 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".

The United States Air Force currently employs a designation and naming system to identify all aircraft type with distinct names. Until 1962, both the Army and Air Force maintained one system, while the United States Navy maintained a separate system. In 1962, these were unified into a single system heavily reflecting the Army/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 designated under the pre-1962 United States Navy designation system. For these aircraft, see List of military aircraft of the United States (naval).

[edit] Army Air Service, 1919-1924

Prior to 1919, all planes flown by the Army Air Service were referred to by the designation given to them by their manufacturer. In September 1919, the Army Air Service decided that it needed some 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.

[edit] Bomber

Until 1926, the Army Air Service had three sequences for bombers. Light bombers were indicated by the LB- prefix, medium bombers by the B- prefix, and heavy bombers by the HB- prefix. In 1926, the three-category system was scrapped and all bombers subsequently built were placed in the B- sequence.
