The 568th Air Defense Group is a disbanded United States Air Force organization. Its last assignment was with Air Defense Command (ADC)'s 4709th Air Defense Wing at McGuire Air Force Base (AFB), New Jersey, where it was inactivated in 1954. The group was originally activated as a support unit for a combat group at the end of World War II on Guam, but was soon inactivated. The group was activated once again in 1952 to replace the support elements of the inactivating 52d Fighter-Interceptor Wing. A year later ADC established it as an operational headquarters for fighter-interceptor squadrons as well. It was replaced in 1954 when ADC transferred McGuire to Military Air Transport Service and its operational squadrons were transferred to other ADC units.
World War II 
The group was activated toward the end of World War II as the 568th Air Service Group 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. It was designed to support a single combat group. Its 1031st Air Engineering Squadron provided maintenance that was beyond the capability of the combat group, its 1032nd Air Materiel Squadron handled all supply matters, and its Headquarters & Base Services Squadron provided other support. Provided support for one combat group in the Pacific Theater. It was disbanded in 1948.
Cold War 
During the Cold War the group was reconstituted, redesignated as the 568th Air Base Group, and activated at McGuire AFB in 1952 in a major reorganization of ADC responding to ADC's difficulty under the existing wing base organizational structure in deploying fighter squadrons to best advantage. It replaced the 52nd Air Base Group as host unit for McGuire. Assigned seven squadrons to perform its support responsibilities. Also maintained aircraft stationed at McGuire.
The group was redesignated as the 568th Air Defense Group in 1953 and assumed responsibility for air defense of Northeast United States. It was assigned the 2d Fighter-Interceptor Squadron (FIS) and 5th FIS, flying F-94 Starfire aircraft from the 4709th Defense Wing as its operational elements. The 2nd FIS and 5th FIS were already stationed at McGuire. The same month that it transferred to the 568th the 2nd FIS briefly traded its F-94s for F-84 Thunderjet Aircraft. Both the 2nd FIS and the 5th FIS converted to radar equipped F-86 Sabres in July 1953. In 1954, McGuire AFB transferred from ADC to Military Air Transport Service, and the group was inactivated. The group's support components were replaced by elements of the 1611th Air Transport Wing Its operational flying squadrons were assigned back to the 4709th Air Defense Wing. The group was disbanded once again in 1984.
