The 484th Fighter-Interceptor Squadron is an inactive United States Air Force unit. Its last assignment was with the 473d Fighter Group at K. I. Sawyer Air Force Base, Michigan, where it was inactivated on 16 February 1959. During world War II, the squadron was activated as a replacement training unit, but never became operational.


World War II[edit]

The squadron was activated as the 484th Fighter Squadron in November 1943 at Grand Central Air Terminal, California, forming one of the three original squadrons of the 473d Fighter Group, The squadron was intended to become a Lockheed P-38 Lightning replacement training unit,[1] but operated Bell P-39 Airacobras and other aircraft, and never became operational. The squadron moved to Ephrata Army Air Base, Washington at the end of March 1944, along with other elements of the 473d Group.[2][3] Upon arrival at Ephrata, the squadron was disbanded and its personnel used to form part of the cadre of the 430th AAF Base Unit (Replacement Training Unit, Fighter, Single Engine).[2][4]

Cold War Air Defense[edit]

The 473d Fighter Group was activated again in 1956 by Air Defense Command to open K. I. Sawyer Air Force Base, and the 484th Fighter-Interceptor Squadron was activated as its operational squadron, authorized Northrop F-89 Scorpion aircraft.[5] However, the squadron never received its aircraft and was inactivated before the runways at K.I. Sawyer were ready to receive operational aircraft.[2][6]
