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 radar squadrons,[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. 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]
