The group was formed to provide a single command and support organization for the two fighter interceptor squadrons of Air Defense Command, that were tenants at Westover, a Strategic Air Command (SAC) base. It was also assigned a maintenance squadron to perform aircraft maintenance. It was discontinued after the 324th Fighter-Interceptor Squadron moved in 1958, leaving only a single fighter squadron at Westover.
The group was assigned the 324th FIS and 337th FIS, flying radar equipped and rocket armed North American F-86D Sabre aircraft[3][4] as its operational components,[5][6] to provide air defense of New England. These squadrons were already stationed at Westover and had been assigned to the Boston Air Defense Sector.[5][6] In August, maintenance for the two fighter squadrons was combined in the 603rd Consolidated Aircraft Maintenance Squadron (CAMS), which was activated at Westover.[7] The 324th FIS and 337th FIS upgraded to newer model Sabres with data link for interception control through the Semi-Automatic Ground Environment system in the fall of 1957.[3][4] In the spring of 1958, the 337th FIS converted to Lockheed F-104 Starfighter aircraft.[3]
The group was discontinued when the 324th FIS departed for Morocco, leaving only a single operational ADC squadron at Westover.[1][5] The 603rd CAMS was also inactivated, while the 337th FIS was then assigned directly to the Boston Air Defense Sector.[6][7]
