Boron Air Force Station  Boron Air Force Station is a closed United States Air Force General Surveillance Radar station. It is located northeast of Boron, California. It was closed by the Air Force in 1975 and turned over to the Federal Aviation Administration (FAA). The radar site is still operated by the FAA as part of the Joint Surveillance System (JSS). Boron 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 750th Aircraft Control and Warning Squadron was assigned to Atolia, California on 28 January 1952. It assumed coverage responsibilities formerly held by the temporary "Lashup" site at Edwards AFB site (L-40), and was operating two AN/FPS-10 radars at this new 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. Atolia AFS was renamed "Boron Air Force Station" on 1 December 1953. The AN/FPS-10 search radar at Boron remained until 1959. In 1958 an AN/FPS-6 replaced the AN/FPS-10 height-finder radar. A second height-finder radar (AN/FPS-6A) was installed in 1959. During 1961 Boron 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 750th 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. In addition to the main site, a Ground Air Transmit Receive (GATR) site was located 3.5 miles north of the main site, at a heading of 335 degrees, in order to gain some distance from the high-powered RF energy from the search radar systems. The GATR sites were used to communicate audibly to intercept aircraft in order to vector them to airborne targets.
