The group was activated once again in 1953, when Air Defense Command 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 52d Fighter Group in a project that replaced air defense groups commanding fighter squadrons with fighter groups with distinguished records during World War II.
History
World War II and Post-War
The group was activated as the 519th Air Service Group in Italy shortly before the end of World War II in early 1945 as part of a reorganization of Army Air Forces (AAF) support groups in which the AAF replaced service groups that included personnel from other branches of the Army and supported two combat groups with air service groups including only Air Corps units.[1] Designed to support a single combat group,[2] Its 945th Air Engineering Squadron provided maintenance that was beyond the capability of the combat group, its 769th Air Materiel Squadron handled all supply matters, and its Headquarters & Base Services Squadron provided other support.[2] It supported the 485th Bombardment Group in Italy.[3] The group returned to the US, where it continued to support heavy bombardment groups. The group was scheduled to move overseas in 1946, but its movement was cancelled.[4] It was reduced to nominal strength of 4 officers and 7 enlisted men in March 1946, but re-manned in April.[5] The group deployed to Alaska with the 97th Bombardment Group.[6][7] It was replaced by 97th Airdrome Group, 97th Maintenance & Supply Group, and 97th Station Medical Group as part of the Air Force Wing/Base reorganization (Hobson Plan) in 1947, which was designed to unify control at air bases.[6][8][9] It was disbanded in 1948.[10]
Cold War
The 519th was reconstituted, redesignated as an air defense group, and activated at Suffolk County Air Force Base, New York in 1953[11] with responsibility for air defense of the Northeastern United States.[citation needed] It was assigned the 45th and 75th Fighter-Interceptor Squadrons (FIS), which were already stationed at Suffolk County, flying North American F-86 Sabres[12][13] as its operational components.[14][15] The 45th and 75th FIS had been assigned directly to the 4709th Defense Wing.[14][15] The group replaced the 77th Air Base Squadron as USAF host unit at Suffolk County. It was assigned three squadrons to perform its support responsibilities.[16][17] Eight days after the group activated, the 331st Fighter-Interceptor Squadron, equipped with a radar equipped and Mighty Mouse rocket armed model of the Sabre[18] was activated and assigned to the group.[19] In May 1953, the 45th FIS moved to Morocco and was reassigned away from the group.[14] Later in 1953, the 75th FIS upgraded to improved radar equipped Sabres.[13]
The 519th was inactivated[11] and replaced by the 52d Fighter Group (Air Defense)[20][21] as result of Air Defense Command's Project Arrow, which was designed to bring back on the active list the fighter units which had compiled memorable records in the two world wars.[22] The group was disbanded once again in 1984.[23]
