|Branch||United States Air Force|
|Part of||Air Defense Command|
The 4700th Air Defense Group is a discontinued United States Air Force (USAF) organization. Its last assignment was with the 4709th Air Defense Wing at Stewart Air Force Base, New York. It was activated in 1950 as a support unit for USAF units at Stewart. In 1954, it assumed an operational mission and was assigned two interceptor squadrons. The group was discontinued on 18 August 1955 and its personnel and equipment were transferred to the 329th Fighter Group (Air Defense) as part of Project Arrow, an Air Defense Command project to air defense groups with fighter units with distinguished histories from World War I or World War II.
The group was organized 1 December 1950 as the 4700th Air Base Group to replace the 4400th Air Base Group as the USAF host unit at Stewart Air Force Base, New York in preparation for the transfer of Stewart to Air Defense Command (ADC) from Continental Air Command (CONAC). It was assigned three squadrons to perform its duties as host. The 4700th was assigned to Eastern Air Defense Force. It transferred with Eastern Air Defense Force from Continental Air Command to Air Defense Command (ADC) upon ADC's reactivation in January 1951.
The 4700th was redesignated as an air defense group in 1954 and reassigned to the 4709th Air Defense Wing with responsibility for air defense of the New York City area. The group was assigned the 330th and the 539th Fighter-Interceptor Squadrons (FIS), which were already stationed at Stewart, flying North American F-86 Sabre fighter aircraft as its operational components. The 330th and 539th FIS had been assigned directly to the 4709th Air Defense Wing. In January 1955, the 330th FIS and 539th FIS converted to more capable radar equipped and Mighty Mouse rocket armed North American F-86Ds.
The group was replaced by the 329th Fighter Group in 1955 as part 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.
