History

The group was first activated in Italy in late 1944 as the 520th Air Service Group[1] 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. Designed to support a single combat group.[2] Its 946th Air Engineering Squadron provided maintenance that was beyond the capability of the combat group,[3] its 770th Air Materiel Squadron handled all supply matters,[4] and its Headquarters & Base Services Squadron provided other support.[2][4] The group supported the 340th Bombardment Group in Italy. The group returned to the US and was inactivated in late 1945. It was disbanded in 1948.[5]


The group was reconsituted, redesignated as the 520th Air Defense Group, and activated at Truax Field in 1953[6] with responsibility for air defense of of Great Lakes area.[citation needed] It was assigned the 432d Fighter-Interceptor Squadron (FIS) and 433d Fighter-Interceptor Squadron, which were already stationed at Truax Field as its operational components.[7] The 432d FIS was flying F-86 Sabres,[8] while the 433d FIS was flying Northrop F-89 Scorpions[8] Both squadrons had been assigned directly to the 31st Air Division.[7] The group also replaced the 78th Air Base Squadron as the USAF host unit for Truax Field. It was assigned three squadrons to perform its support responsibilities.[9]


In March 1953, the 432d FIS converted to a later radar equipped model of the "Sabre".[8] In July 1954, the 433d FIS moved to Alaska and was reassigned.[7] The following month, the 456th Fighter-Interceptor Squadron was activated to replace the 433d FIS.[10] The 456th FIS was also equipped with "Sabres".[11] The group was inactivated[6] and replaced by the 327th Fighter Group (Air Defense)[12] as part 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.[13] The group was disbanded once again in 1984.[14]
