"The 500th Air Defense Group is a disbanded United States Air Force (USAF) organization. Its last assignment was with the 4708th Air Defense Wing at Greater Pittsburgh Airport, Pennsylvania. It was last active on 18 August 1955. The group was originally activated as a support group at the end of World War II and provided logistics and administrative support for the 67th Tactical Reconnaissance Group in Germany and the United States until 1946, when the two groups were inactivated. The groups were activated again in 1947, but the 500th was soon discontinued when the USAF reorganized its combat and support units in the wing base reorganization in which a single wing was responsible for a base. The group was activated once again in 1953, when ADC established it as the headquarters for a dispersed fighter-interceptor squadron and the medical, maintenance, and administrative squadrons supporting it. It was replaced in 1955 when ADC transferred its mission, equipment, and personnel to the 54th Fighter Group in a project that replaced air defense groups commanding fighter squadrons with fighter groups with distinguished records during World War II."@en . . . . . .
