Elliston Ridge Air Station

The site was established in 1943 as a United States Army anti-aircraft spotting station (Codename: Duo) with an SCR-271 early warning radar. Fifty-two members (three officers and 49 enlisted men) of the 685th Air Warning Company were stationed at Elliston from winter 1943 to November 1944.

In 1957 a manned Gap Filler radar station was constructed, funded by the United States Air Force, under operational control of Red Cliff Air Station and part of Pinetree Line of Ground-Control Intercept (GCI) radar sites.

The station was assigned to Aerospace Defense Command in 1957, and was given designation "N-22B" (later "C-22B)." Aerospace Defense Command stationed the 642d Aircraft Control and Warning Squadron at the station in 1957. It operated an AN/FPS-14 manned Gap Filler search radar.^[2]
