caption_attribution_description: English: NASA's Research Aircraft Fleet on ramp at Dryden Flight Research Center: X-31, F-15 ACTIVE, SR-71, F-106, F-16XL #2, X-38, Radio Controlled Mothership and X-36.
context_page_description: This list of military aircraft of the United States includes prototype, pre-production, and operational types. 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, 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. It also does not include aircraft designated under the pre-1962 United States Navy designation system.

For aircraft in service, see the list of active United States military aircraft. Prototypes are normally prefixed with "X" and are 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 with "Y".
