This is a table of 1962 United States Tri-Service aircraft designation system with selected letter sequences and number. Two previous USAF/AAF/AAC number series are included due to their impact and partial incorporation into the tri-service system (A, B, C, F and O reset to one, but # carryover existed).
The United States department of Defense was established in 1949, the old name Department of War was retired in 1947. In 1962 separate aircraft naming schemes were unified, but out of convenience many numbers carried over. For example, the P-38 Lightning, which also was used as the F-4 and F-5 for reconnaissance and FO in the Navy, became the F-38. In 1948 the Pursuit series designated P, switched to being called F for fighter, which was continued in 1962. Much later the B series were restarted back at 1, but numbered additions began being made where the old C left off in the 21st century.
