Port Austin Air Force Station
Port Austin Air Force Station (ADC ID: P-61, NORAD ID: Z-61) is a closed United States Air Force General Surveillance Radar station. It is located south-southwest Port Austin, Michigan. It was closed in 1988 by the Air Force. After the station's closure, it was replaced by the Federal Aviation Administration (FAA) at Canton, Michigan (near Detroit) as part of the Joint Surveillance System (JSS), designated by NORAD as Eastern Air Defense Sector (EADS) Ground Equipment Facility J-62. History Port Austin 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 754th Aircraft Co ...

Air Defense Command
Aerospace Defense Command was a major command (military formation), command of the United States Air Force, responsible for continental air defense. It was activated in 1968 and disbanded in 1980. Its predecessor, Air Defense Command, was established in 1946, briefly inactivated in 1950, reactivated in 1951, and then redesignated ''Aerospace'' rather than ''Air'' in 1968. Its mission was to provide air defense of the Continental United States (CONUS). It directly controlled all active measures, and was tasked to coordinate all passive means of air defense. Air defense during World War II Continental United States air defense forces during World War II were initially under the command of the four air districts – Northeast Air District, Northwest Air District, Southeast Air District, and Southwest Air District. The air districts were established on 16 January 1941, before the Pearl Harbor attack. The four air districts also handled USAAF combat training with the Army Ground F ...

AN/FPS-24
The AN/FPS-24 Radar was a long range early warning radar used by the United States Air Force Air Defense Command. It used a two-frequency signal in order to avoid fluctuation loss, which causes signals on single-frequency radars to fade in and out as the target moves. Reducing this effect results in a much steadier signal. General Electric was the primary contractor for the design, which operated in the very high frequency (VHF) at 214 to 236 MHz. Construction Twelve systems were built between 1958 and 1962 at various locations around the United States. Problems with the design were revealed during initial testing Eufaula AFS (Eufaula, Alabama) in 1960, resulting in modifications. Additional problems occurred in 1961 when deployment of the first production model at Point Arena Air Force Station in California. revealed bearing problems due to the antenna weight. Failures of the hydrostatic bearing often caused the early closure of some radar sites due to catastrophic damage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

AN/FPS-116
The AN/FPS-6 Radar was a long-range height finding radar used by the United States Air Force's Air Defense Command. The AN/FPS-6 radar was introduced into service in the late 1950s and served as the principal height-finder radar for the United States for several decades thereafter. It was also used by the Royal Air Force alongside their AMES Type 80s. Built by General Electric, the S-band radar operated on a frequency of 2700 to 2900 MHz. Between 1953 and 1960, about 450 units of the AN/FPS-6 and the mobile AN/MPS-14 version were produced. The AN/FPS-90 and AN/FPS-116 radars were identical to the AN/FPS-6 except for receiver modifications. Operation The radar consisted of an antenna group, a transmitter group, a receiver group, and an ancillary group. Most fixed sites had a remote group, which allowed the control of the radar from inside the operations center. Also located in operations, was the anti-jam receivers. These receivers were fed with raw video from the tower receiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AN/FPS-91
The AN/FPS-20 was a widely used L band early warning and ground-controlled interception radar system employed by the United States Air Force Air Defense Command, the NORAD Pinetree Line in Canada, the USAF CONAD in the continental United States, and a variety of other users. The design started life as the Bendix AN/FPS-3 in 1950, was upgraded to the FPS-20, then spawned over a dozen different variants as additional upgrades were applied. The FPS-20 formed the backbone of the US air defense network through the early Cold War with over 200 units deployed. Most FPS-20 sites were replaced by modern equipment in the late 1960s, although a number were turned over to the FAA, modified for air traffic control use, and became ARSR-60s. The first AN/FPS-3 arrived in December 1950, slated for installation at Eniwetok Atoll to control aircraft involved in the atomic bomb tests of early 1951. Over the next few years, 48 FPS-3s were installed to replace older systems in the Lashup Radar Network ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
