Former Calumet Air Force Station

The 665th AC&W Squadron began operating AN/FPS-3 and AN/FPS-5 radars at this northern Michigan site in early 1953. In 1956 an AN/FPS-6 replaced the AN/FPS-5 height-finder radar. In 1958 an AN/FPS-20 search radar was deployed at this site. By 1961 this radar was upgraded and redesignated as an AN/FPS-64. A turn-over of equipment in 1963 left the site with an AN/FPS-27 search radar along with AN/FPS-26A and AN/FPS-90 height-finder radars. The AN/FPS-90 was removed in the late 1970’s. Calumet came under TAC jurisdiction in October 1979. The station then underwent cease-operations about that time, and the AN/FPS-26A height-finder radar was removed, but the site closing was soon reversed. Calumet was then reconfigured as a “blue-suit” JSS site, initially with only the AN/FPS-27. An AN/FPS-91A replaced the AN/FPS-27, and later an AN/FPS-116 height-finder radar was installed. In 1988, the site finally did close once and for all. The former station was also used by Keweenaw Academy, a reform school.
