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). History 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, Secretary of the Air Force Thomas K. Finletter asked Secretary of Defense Louis A. Johnson on 11 July 1950 for approval to expedite construction of the permanent network. Receiving approval 10 days later, the Air Force directed the Army 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 ...

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 ...

Semi-Automatic Ground Environment
The Semi-Automatic Ground Environment (SAGE) was a system of mainframe computer, large computers and associated computer network, networking equipment that coordinated data from many radar sites and processed it to produce a single unified image of the airspace over a wide area. SAGE directed and controlled the NORAD response to a possible Soviet air attack, operating in this role from the late 1950s into the 1980s. Its enormous computers and huge displays remain a part of cold war lore, and after decommissioning were common props in movies such as ''Dr. Strangelove'' and Colossus: The Forbin Project, ''Colossus'', and on science fiction TV series such as ''The Time Tunnel''. The processing power behind SAGE was supplied by the largest discrete component-based computer ever built, the IBM-manufactured AN/FSQ-7 Combat Direction Central, AN/FSQ-7. Each SAGE Direction Center (DC) housed an FSQ-7 which occupied an entire floor, approximately not including supporting equipment. The F ...

Federal Bureau Of Prisons
The Federal Bureau of Prisons (BOP) is a United States federal law enforcement agency under the Department of Justice that is responsible for the care, custody, and control of incarcerated individuals who have committed federal crimes; that is, violations of the United States Code. History The federal prison system had existed for more than 30 years before the BOP was established. Although its wardens functioned almost autonomously, the Superintendent of Prisons, a Department of Justice official in Washington, was nominally in charge of federal prisons. The passage of the "Three Prisons Act" in 1891 authorized the first three federal penitentiaries: USP Leavenworth, USP Atlanta, and USP McNeil Island with limited supervision by the Department of Justice. Until 1907, prison matters were handled by the Justice Department General Agent, with responsibility for Justice Department accounts, oversight of internal operations, and certain criminal investigations, as well as priso ...

Minter Field Army Airfield
Shafter Airport , also known as Minter Field and formerly known as Air Corps Basic Flying School, is a public use airport located east of the central business district of Shafter and 14 miles northwest of Bakersfield, a city in Kern County, California, United States. Originally a World War II primary training facility for pilots, it is currently a public airport owned by the Minter Field Airport District. This airport is included in the National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a ''general aviation'' facility. History Lerdo Field, as the airport was initially known during World War II, was first opened in June 1941 when the United States Army Air Corps (USAAC) dispatched a small garrison of airmen to open an airfield at Shafter. The name was derived from close proximity to the highway of the same name. The airfield commander utilized Bakersfield College as his headquarters, while airmen were quartered in temporary facilities f ...

AN/FPS-14
The AN/FPS-14 was a medium-range search Radar used by the United States Air Force Air Defense Command. This medium-range search radar was designed and built by Bendix as a SAGE system gap-filler radar to provide low-altitude coverage. Operating in the S-band at a frequency between 2700 and 2900 MHz, the AN/FPS-14 could detect at a range of 65 miles. The system was deployed in the late 1950s and 1960s at unmanned radar facilities (called "Gap Fillers") designed to fill the low-altitude gaps between manned long-range radar stations. Gaps in coverage existed due to the curvature of the earth, mountains, hills, valleys, rivers, and so forth. The typical unmanned gap-filler radar annex consisted of a small L-shaped cinder-block building, with the radar equipment and the data-transmission equipment in one section and one or more diesel generators in the other section. These unmanned gap-filler sites generally had a three-legged radar tower about 85 feet tall where the AN/FP ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AN/FPS-67
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] |
AN/FPS-90
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-26A
The Avco AN/FPS-26 Radar was an Air Defense Command height finder radar developed in the Frequency Diversity Program with a tunable 3-cavity power klystron for electronic counter-countermeasures (e.g. to counter jamming). Accepted by the Rome Air Development Center on 20 January 1960 for use at SAGE radar stations, the AN/FPS-26 processed height-finder requests (e.g., from Air Defense Direction Centers) by positioning to the azimuth of a target aircraft using a high-pressure hydraulic drive, then "nodding" in either a default automatic mode or by operator command. The inflatable radome required a minimum pressure to prevent contact with the antenna which would result in damage to both (technicians accessed the antenna deck via an air lock.) To maintain high dielectric strength, the waveguide was pressurized with sulfur hexafluoride (SF6), which technicians were warned would produce deadly fluorine if waveguide arcing occurred. FPS-26 units were installed at Luke AFB, MacDill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frequency Diversity
Frequency is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as ''temporal frequency'' for clarity, and is distinct from ''angular frequency''. Frequency is measured in hertz (Hz) which is equal to one event per second. The period is the interval of time between events, so the period is the reciprocal of the frequency. For example, if a heart beats at a frequency of 120 times a minute (2 hertz), the period, —the interval at which the beats repeat—is half a second (60 seconds divided by 120 beats). Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light. Definitions and units For cyclical phenomena such as oscillations, waves, or for examples of simple harmonic motion, the term ''frequency'' is defined as the number of cycles or vibrations per unit of time.

AN/FPS-35
The AN/FPS-35 frequency diversity radar was a long range search radar used in the early 1960s. It was one of the largest air defense radars ever produced, with its antenna and supporting structure mounted on one of the largest rolling-element bearings in the world (with a ball pitch of 12 ft 7 inches in diameter.). Overview Sperry Corporation built 12 long range radars (picking up objects 200 miles away) in the 1960s to succeed existing Semi Automatic Ground Environment (SAGE) to provide enhanced electronic countermeasures (ECM). The systems operated at 420 to 450 MHz. The antennas weighed and had numerous problems. The concrete tower bases were high and square in side dimensions. The prototype was developed at the Thomasville Aircraft Control and Warning Station in Thomasville, Alabama. The enclosed radar towers that supported all 12 of the FPS-35 antennas were prominent landmarks. All these radar towers were of the same basic design with 10 made primarily from concr ...

F-106 Delta Dart
The Convair F-106 Delta Dart was the primary all-weather interceptor aircraft of the United States Air Force from the 1960s through to the 1980s. Designed as the so-called "Ultimate Interceptor", it proved to be the last specialist interceptor in U.S. Air Force service to date. It was gradually retired during the 1980s, with the QF-106 drone conversions of the aircraft being used until 1998 under the ''Pacer Six'' program.Winchester 2006, p. 55. Development Antecedents The F-106 was the ultimate development of the USAF's 1954 interceptor program of the early 1950s. The initial winner of this competition had been the F-102 Delta Dagger, but early versions of this aircraft had demonstrated extremely poor performance, limited to subsonic speeds and relatively low altitudes. During the testing program the F-102 underwent numerous changes to improve its performance, notably the application of the area rule to the fuselage shaping and a change of engine, and the dropping of the advan ...
