The 4733d Air Defense Group is a discontinued
United States Air Force organization. Its last assignment was with the
64th Air Division at
Frobisher Bay, Baffin Island, Northwest Territories, Canada, where it was discontinued in 1958. The
group was formed in 1957 when ADC assumed responsibility for
air defense of Northern Canada from
Northeast Air Command, including support for remote
Distant Early Warning Line (DEW Line) radar sites. It also controlled two
squadrons operating
radars at dispersed locations. It was discontinued in 1958 and its DEW Line support mission transferred to the 4601st Support Group and its radar squadrons to the
4732d Air Defense Group in Newfoundland.
History
The
group was organized in the fall of 1957 at Frobisher Bay by
Air Defense Command (ADC) when ADC assumed the mission of
Northeast Air Command (NEAC) after NEAC's inactivation.[1] The group was assigned two general surveillance
radarsquadrons,[2][3] stationed in the high latitudes of northern Canada, which had been assigned directly to NEAC's 64th Air Division. The group's mission was to provide detection and reporting of aircraft in the northern portion of North America and to support
Distant Early Warning Line (DEW) radar sites.[citation needed] The group was discontinued in 1958 and the DEW support mission was taken over by 4601st Support Group (DEW),
Paramus, New Jersey,[1][4][5] while its radar stations were reassigned to the
4732d Air Defense Group at
Goose AFB, Labrador.[2][3]
