The 564th Air Defense Group is a disbanded United States Air Force organization. Its last assignment was with the 4707th Air Defense Wing, at Otis Air Force Base, Massachusetts, where it was inactivated in 1955. The group was originally activated as the 564th Air Service Group, 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 as the 564th Air Base Group to replace the support elements of the inactivating 33d Fighter-Interceptor Wing. A year later Air Defense Command (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 33d Fighter Group in a project that replaced air defense groups commanding fighter squadrons with fighter groups with distinguished records during World War II.
