Ground Equipment Facility J-31 (San Pedro Hill Air Force Station during the Cold War) is a Joint Surveillance System radar site of the Western Air Defense Sector (WADS) and the Federal Aviation Administration's air traffic control radar network [1] for the Los Angeles Air Route Traffic Control Center. The facility's Air Route Surveillance Radar Model 1E with an ATCBI-6 beacon interrogator system are operated by the FAA[3] and provide sector data to North American Aerospace Defense Command. The site provided Semi-Automatic Ground Environment data to the 1959-66 Norton AFB Direction Center for the USAF Los Angeles Air Defense Sector. The site also provided Project Nike data to the 1960-74 Fort MacArthur Direction Center ~3 mi (4.8 km) away for the smaller US Army Los Angeles Defense Area[4]—as well as gap-filler[specify] radar coverage for the 1963-74 Integrated Fire Control area of Malibu Nike battery LA-78 on San Vicente Mountain.[5]
History
[edit]The "ADC/FAA joint-use facility" began operations in 1961 with an FAA ARSR-1C radar.[1] After the April 1, 1961, move of the 670th Radar Squadron (SAGE)--formerly the 670th AC&W Squadron—from San Clemente Island Air Force Station, the Los Angeles Air Defense Sector was activated June 1.[6] The squadron was assigned to the "Fort MacArthur AI"[6] (Army Installation) and operated the San Pedro Hill radars which included a General Electric AN/FPS-6B Radar and an Avco AN/FPS-26 Radar for height finding. In 1964, the station's Westinghouse AN/FPS-27 Radar was installed (removed 1969) and the AN/FPS-6B was modified to an AN/FPS-90.[citation needed] In April 1976 the squadron was redesignated Detachment 1 of Luke AFB's 26th Air Defense Squadron[6] (the AN/FPS-26A was removed in this time frame).[citation needed]
The radar station with 18 military & 5 civilians was planned for transfer after the 1978 Base Realignment and Closure Commission.[7] After the station transferred to the FAA when Aerospace Defense Command was inactivated, the Air Force continued to operate the AN/FPS-90 height-finder by then modified to an AN/FPS-116 (removed c. 1988).[8] In the late 1990s, the Air Force terminated the data-tie at San Pedro Hill and established a data-tie with the new Navy-installed ARSR-4 radar at San Clemente Island's Mount Thirst. The Raytheon ARSR-1E Radar at San Pedro Hill was in use by November 2010.[3]
