566th Air Defense Group
|566th Air Defense Group
|Branch||United States Air Force|
|Part of||Air Defense Command|
The 566th Air Defense Group is a disbanded unit of the United States Air Force. Its last assignment was with the 28th Air Division at Hamilton Air Force Base, California where it was inactivated on 18 August 1955. The group was originally activated as a support unit for a combat group at the end of World War II but never deployed before it was inactivated in 1945.
The group was activated once again in 1952 to replace the support elements of the inactivating 78th Fighter-Interceptor Wing. A year later ADC established it as an operational headquarters for fighter-interceptor squadrons as well. It was replaced in 1955 when ADC transferred its mission, equipment, and personnel to the 78th Fighter Group in a project that replaced air defense groups commanding fighter squadrons with fighter groups with distinguished records during World War II.
World War II
The group was activated toward the end of World War II as the 566th Air Service Group in 1944 and trained to support a single combat group. Its 984th Air Engineering Squadron would provide maintenance that was beyond the capability of the combat group, its 1004th Air Materiel Squadron would handle all supply matters, and its Headquarters & Base Services Squadron would provide other support. The group was inactivated before it could be deployed overseas. It was disbanded in 1948.
During the Cold War the group was reconstituted, redesignated as the 566th Air Base Group, and activated at Hamilton Air Force Base in 1952 in a major reorganization of Air Defense Command (ADC) responding to ADC's difficulty under the existing wing base organizational structure in deploying fighter squadrons to best advantage. It replaced the 78th Air Base Group as host unit for Hamilton. It was assigned eight squadrons and one flight to perform its support responsibilities. The group also assumed responsibility to maintain aircraft stationed at Hamilton from the inactivating 78th Maintenance & Supply Group, while the operational elements of the 78th Fighter-Interceptor Wing were assigned to the 28th Air Division.
The 566th was redesignated the 566th Air Defense Group and assumed responsibility for air defense of the Northern California. It was assigned the 84th Fighter-Interceptor Squadron (FIS), flying 20mm cannon armed and airborne intercept radar equipped F-89 Scorpion aircraft from the 28th Air Division as its operational element. The 84th FIS was already stationed at Hamilton Air Force Base. In March, a second operational squadron, the 496th Fighter-Interceptor Squadron, was activated at Hamilton and assigned to the group. The 496th FIS was initially equipped with outmoded World War II era F-51 Mustang Aircraft. In April, the 83rd FIS traded its Scorpions for F-94 "Starfire" aircraft. and to later model Starfire, armed with HVAR rockets, before the end of the year. The 496th FIS, in turn, converted to North American F-86 Sabres (also with radar and HVAR rockets) during 1953. In February 1954, the 325th Fighter-Interceptor Squadron at Travis Air Force Base, California, also flying Sabres, was assigned to the group. Ten days after its assignment, the 325th FIS moved from Travis to Hamilton. A few months later, in July, the group once again had only two operational squadrons when the 496th FIS transferred to Europe and was assigned elsewhere. The 566th was inactivated and replaced by the 78th Fighter Group (Air Defense) on 18 August 1955 as result of ADC'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. The group was disbanded once again in 1984.
