The 4730th Air Defense Group is a discontinued United States Air Force organization. Its last assignment was with the New York Air Defense Sector at McGuire Air Force Base, New Jersey, where it was discontinued in 1959. The group was formed to provide a single command and support organization for the two fighter interceptor squadrons of Air Defense Command (ADC), that were tenants at McGuire, a Military Air Transport Service (MATS) base. It was also assigned a maintenance squadron to perform aircraft maintenance. It was discontinued when the 332d Fighter-Interceptor Squadron moved in 1959, leaving only a single fighter squadron at McGuire.


332d FIS F-102A at McGuire AFB

The group was established to provide a headquarters for Air Defense Command (ADC) Fighter-Interceptor Squadrons (FIS) stationed at McGuire AFB,[1] a Military Air Transport Service base,[2] and whose 1611th Air Base Group acted as host base organization.[3] Assigned the 332d FIS and 539th FIS, flying radar equipped and rocket armed F-86 Sabre aircraft,[4][5] some of which were equipped with data link for interception control through the Semi-Automatic Ground Environment system as its operational components[6][7] to train and maintain tactical flying units to defend the Mid-Atlantic United States. These squadrons were already stationed at McGuire and had been assigned to the New York Air Defense Sector.[6][7] Maintenance for the two squadrons was combined in the 601st Consolidated Aircraft Maintenance Squadron (CAMS), which was activated at McGuire.[8] The 332d FIS converted to F-102 Delta Dagger aircraft in July 1957,[4] while the 539th FIS retained its F-86s until the Spring of 1959, when it converted to F-106 Delta Darts.[5] The group was discontinued[1] shortly after the 332d FIS departed for Louisiana, leaving only a single operational ADC squadron at McGuire.[6] The 601st CAMS was also inactivated, while the 539th FIS was then assigned directly to the New York Air Defense Sector.[7]
