List of United States Tri-Service aircraft designations

This list of United States Tri-Service aircraft designations includes prototype, pre-production and operational type designations under the United States Tri-Service aircraft designation system, which replaced the 1924 Air Force, 1922 Navy, and 1956 Army designation systems in 1962.

For pre-1962 Air Force aircraft designations, see List of United States Air Force aircraft designations (1919–1962). For pre-1962 Navy aircraft designations, see List of United States Navy aircraft designations (pre-1962). For aircraft that did not receive formal designations—including those procured before 1919 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.
