# 4683d Air Defense Wing

The 4683d Air Defense Wing is a discontinued United States Air Force (USAF) organization. Its last assignment was with Aerospace Defense Command (ADC)'s Goose Air Defense Sector at Thule Air Base, Greenland, where it was discontinued in 1965.
The wing was organized in 1960 and assigned a fighter interceptor squadron and a squadron operating a radar for ground controlled interception. The 4683d also acted as the host organization at Thule until October, when support units were transferred to the 4683d Air Base Group, which was attached to the wing, but assigned to the 64th Air Division in Newfoundland. It supported the Ballistic Missile Early Warning System when the system was activated at Thule, but was discontinued when that mission supplanted the wing's traditional air defense mission.

## History

The 4683d Air Defense Wing was established in 1960 when Air Defense Command (ADC) assumed host responsibility for Thule Air Base from Strategic Air Command. Its operational mission was to act at the command and control echelon, controlling both a radar and a fighter squadron in Greenland to provide forward air defense of northeast North America. Through the attached 4683rd Air Base Group, the wing also acted as the United States Air Force host organization for Thule. The wing also provided support for an Army Nike Missile air defense unit.
The 931st Aircraft Control and Warning Squadron, already at Thule, was reassigned to the wing from the 64th Air Division immediately upon organization of the wing. The 931st was located on Pingarssuit Mountain (Site N-32), 20 miles south of the main base. The wing was assigned the 332d Fighter-Interceptor Squadron, flying Convair F-102 Delta Dagger interceptor aircraft when the squadron moved to Thule from England Air Force Base, Louisiana in September 1960. It also supported the Ballistic Missile Early Warning System (BMEWS) when the system was activated at Thule.
The 332d was inactivated at the end of May 1965. The wing was discontinued in July and replaced as host organization at Thule by the 4683d Air Base Group. The wing's 931st AC&W Sq was assigned to the 4683d Air Base Group until the squadron was inactivated on 24 December 1965. The Army's NIKE operations also ended in 1965, and Thule's primary mission became BMEWS operations.
