RAF Wideawake
RAF Ascension Island , also known as Wideawake Airfield or Ascension Island Auxiliary Field, is a military airfield and facility located on Ascension Island in the Atlantic Ocean. The airfield is jointly operated by the Royal Air Force (RAF) and the United States Space Force (USSF). Under the terms of an international agreement between the UK and US governments, only state aircraft (e.g. military and diplomatic flights) are authorised to land at Ascension; however, it is also open to air services between Saint Helena and Ascension. The facility is home to a U.S. Space Force ground tracking station in support of the Eastern Range and rocket launches from Cape Canaveral Space Force Station in Florida. History In 1939 Ascension became important as a high-frequency direction finding radio station covering trade routes. Wideawake Airfield (named after a noisy colony of sooty terns nearby) was built by the US military in 1942 by arrangement with the British government. The airfield ...

Georgetown, Ascension Island
Georgetown is the capital and chief settlement of Ascension Island, in the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha, situated on the west coast of the island. The town is centred on St Mary's Church, part of the Anglican Diocese of St Helena and the former Exiles Club, built as a Royal Marines barracks at the time of Napoleon's exile to Saint Helena in the early 19th century. The town is named after George III of the United Kingdom, King George III, who reigned at the time the island was claimed for Britain and garrisoned by the Admiralty in 1815. As well as the church, there is a pier, an athletics track, a small supermarket, Royal Mail post office, snackbar, hotel, police station, Georgetown Hospital, dental surgery, and a library. There is no school, however, and pupils travel to Two Boats, Ascension Island, Two Boats village, 3 miles inland. Naval history A naval base was established at Georgetown in 1816 due to British concerns that the Fre ...

Fairey Swordfish
The Fairey Swordfish is a biplane torpedo bomber, designed by the Fairey Aviation Company. Originating in the early 1930s, the Swordfish, nicknamed "Stringbag", was principally operated by the Fleet Air Arm of the Royal Navy. It was also used by the Royal Air Force (RAF), as well as several overseas operators, including the Royal Canadian Air Force (RCAF) and the Royal Netherlands Navy. It was initially operated primarily as a fleet attack aircraft. During its later years, the Swordfish was increasingly used as an Anti-submarine warfare, anti-submarine and Trainer (aircraft), training platform. The type was in frontline service throughout the World War II, Second World War. Despite being outmoded by 1939, the Swordfish achieved some spectacular successes during the war. Notable events included sinking one battleship and damaging two others of the ''Regia Marina'' (the Italian navy) during the Battle of Taranto, and the famous attack on the German battleship Bismarck, German b ...

Cable & Wireless Plc
Cable & Wireless plc was a British telecommunications company. In the mid-1980s, it became the first company in the UK to offer an alternative telephone service to British Telecom (via subsidiary Mercury Communications). The company later offered cable TV to its customers, but it sold its cable assets to NTL in 2000. It remained a significant player in the UK telecoms market and in certain overseas markets, especially in the former British colonies of the Caribbean, where it was formerly the monopoly incumbent. It was also the main supplier of communication in the British South Atlantic, including Saint Helena and the Falkland Islands. It was listed on the London Stock Exchange and was a constituent of the FTSE 100 Index. The company split in March 2010, with its international division demerging to form Cable & Wireless Communications, acquired by Liberty Global in 2015, and since spun-off in 2018 from Liberty Global to Liberty Latin America, while the remainder of the Cable & W ...

Collimation
A collimated beam of light or other electromagnetic radiation has parallel rays, and therefore will spread minimally as it propagates. A perfectly collimated light beam, with no divergence, would not disperse with distance. However, diffraction prevents the creation of any such beam. Light can be approximately collimated by a number of processes, for instance by means of a collimator. Perfectly collimated light is sometimes said to be ''focused at infinity''. Thus, as the distance from a point source increases, the spherical wavefronts become flatter and closer to plane waves, which are perfectly collimated. Other forms of electromagnetic radiation can also be collimated. In radiology, X-rays are collimated to reduce the volume of the patient's tissue that is irradiated, and to remove stray photons that reduce the quality of the x-ray image ("film fog"). In scintigraphy, a gamma ray collimator is used in front of a detector to allow only photons perpendicular to the surface to be ...

Anti-ballistic Missile
An anti-ballistic missile (ABM) is a surface-to-air missile designed to counter ballistic missiles (missile defense). Ballistic missiles are used to deliver nuclear weapon, nuclear, Chemical weapon, chemical, Bioagent, biological, or conventional weapon, conventional warheads in a ballistics, ballistic flight trajectory. The term "anti-ballistic missile" is a generic term conveying a system designed to intercept and destroy any type of ballistic threat; however, it is commonly used for systems specifically designed to counter intercontinental ballistic missiles (ICBMs). Current counter-ICBM systems There are a limited number of systems worldwide that can intercept intercontinental ballistic missiles: * The Russian A-135 anti-ballistic missile system (renamed in 2017 to A-235) is used for the defense of Moscow. It became operational in 1995 and was preceded by the A-35 anti-ballistic missile system. The system uses ABM-4 Gorgon, Gorgon and Gazelle (missile), Gazelle missiles pre ...

Nike Zeus
Nike Zeus was an anti-ballistic missile (ABM) system developed by the US Army during the late 1950s and early 1960s that was designed to destroy incoming Soviet intercontinental ballistic missile warheads before they could hit their targets. It was designed by Bell Labs' Nike team, and was initially based on the earlier Nike Hercules anti-aircraft missile. The original, Zeus A, was designed to intercept warheads in the upper atmosphere, mounting a 25 kiloton W31 nuclear warhead. During development, the concept changed to protect a much larger area and intercept the warheads at higher altitudes. This required the missile to be greatly enlarged into the totally new design, Zeus B, given the tri-service identifier XLIM-49, mounting a 400 kiloton W50 warhead. In several successful tests, the B model proved itself able to intercept warheads, and even satellites. The nature of the strategic threat changed dramatically during the period that Zeus was being developed. Originally ex ...

Operation Black Buck
Operations Black Buck 1 to Black Buck 7 were seven extremely long-range ground attack missions conducted during the 1982 Falklands War by Royal Air Force (RAF) Vulcan bombers of the RAF Waddington Wing, comprising aircraft from 44, 50 and 101 Squadrons, against Argentine positions in the Falkland Islands. Five of the missions completed attacks. The objective of the missions was to attack Port Stanley Airport and its associated defences. The raids, at almost and 16 hours for the round trip, were the longest-ranged bombing raids in history at that time. The Operation Black Buck raids were staged from RAF Ascension Island, close to the Equator. The Vulcan was designed for medium-range missions in Europe and lacked the range to fly to the Falklands without refuelling several times. The RAF's tanker planes were mostly converted Handley Page Victor bombers with similar range, so they too had to be refuelled in the air. A total of eleven tankers were required for two Vulcans (o ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Falklands War
The Falklands War ( es, link=no, Guerra de las Malvinas) was a ten-week undeclared war between Argentina and the United Kingdom in 1982 over two British dependent territories in the South Atlantic: the Falkland Islands and its territorial dependency, South Georgia and the South Sandwich Islands. The conflict began on 2 April, when Argentina invaded and occupied the Falkland Islands, followed by the invasion of South Georgia the next day. On 5 April, the British government dispatched a naval task force to engage the Argentine Navy and Air Force before making an amphibious assault on the islands. The conflict lasted 74 days and ended with an Argentine surrender on 14 June, returning the islands to British control. In total, 649 Argentine military personnel, 255 British military personnel, and three Falkland Islanders were killed during the hostilities. The conflict was a major episode in the protracted dispute over the territories' sovereignt ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
