It was discontinued when Goose Air Defense Sector assumed responsibility for air defense of Newfoundland and Northern Canada.

History
The group was formed in 1957 when Air Defense Command (ADC) assumed responsibility for air defense of Newfoundland from Northeast Air Command (NEAC). It was a tenant organization at Goose AFB, a Strategic Air Command base, whose 4082nd Air Base Group (later 4082nd Combat Support Group) assumed host base duties from NEAC. it controlled both radar and fighter squadrons in Canada. It was assigned the 59th Fighter-Interceptor Squadron (FIS), flying Northrop F-89 Scorpion aircraft, and the 4739th Radar Evaluation Flight, which were already stationed at Goose, and seven remote Aircraft Control & Warning Squadrons as operational elements, all of which were transferred from NEAC. The group provided air defense of northeast North America. The 4732d was discontinued in 1960 and its subordinate units were assigned to the Goose Air Defense Sector.
