Cambria Air Force Station

Cambria Air Force Station is a closed United States Air Force General Surveillance Radar station. It is located 3mi south-southeast of Cambria, California. It was closed in 1980.HistoryCambria Air Force Station was one of twenty-eight stations built as part of the second segment of the Air Defense Command permanent radar network. Prompted by the start of the Korean War, on July 11, 1950, the Secretary of the Air Force asked the Secretary of Defense for approval to expedite construction of the permanent network. Receiving the Defense Secretary’s approval on July 21, the Air Force directed the Corps of Engineers to proceed with construction.The 775th Aircraft Control and Warning Squadron was initially assigned to a temporary "Lashup" site (LP-2) that was established in November 1951 at Cambria equipped with an AN/TPS-1C radar. On 1 December 1953 the permanent station was activated with AN/FPS-3 search and AN/CPS-4 height-finder radars, replacing the earlier site, and initially the station functioned as a Ground-Control Intercept (GCI) and warning station. As a GCI station, the squadron's role was to guide interceptor aircraft toward unidentified intruders picked up on the unit's radar scopes.In 1955 the height-finder radar was replaced by an AN/FPS-6. An AN/FPS-8 search radar also operated for a short time from 1955 to 1956. In 1959 the site featured two AN/FPS-3, and AN/FPS-6 and AN/FPS-6A radars. In 1961 the site received an AN/FPS-7 radar featuring ECCM capability. In 1961 the site also replaced the AN/FPS-6A height-finder radar with an AN/FPS-6B model. In April 1961 Cambria AFS joined the Semi Automatic Ground Environment (SAGE) system, feeding data to DC-17 at Norton AFB, California. After joining, the squadron was redesignated as the 775th Radar Squadron (SAGE) on 1 May 1961. The radar squadron provided information 24/7 the SAGE Direction Center where it was analyzed to determine range, direction altitude speed and whether or not aircraft were friendly or hostile.
