History of Winslow AFS, AZ

Winslow became operational in 1956 with the 904th AC&W Squadron using an AN/FPS-8 search radar. In 1958 an AN/FPS-6A height-finder radar was added. Circa 1961, M-93 became a SAGE site. Also in 1961, an AN/FPS-6B was added. An AN/FPS-24 or -35 FD search radar was planned, but was subsequently cancelled. An AN/FPS-64 was installed reportedly in 1963, but never became operational. During the AN/FPS-64 installation in a new tower, the AN/FPS-8 was replaced by an AN/MPS-11 on a temperate tower. In March 1963 the Air Force ordered Winslow closed; operations ceased 31 May 1963.
