RAF Ballykelly
Royal Air Force Ballykelly or more simply RAF Ballykelly is a former Royal Air Force station which opened in 1941 in Ballykelly, County Londonderry. It closed in 1971 when the site was handed over to the British Army as Shackleton Barracks. A small part of the base has been used as a refuelling point by army helicopters and small fixed-wing aircraft usually operating out of Joint Helicopter Command Flying Station Aldergrove near the town of Antrim. Second World War RAF Ballykelly opened in June 1941 during the Second World War as an airfield for RAF Coastal Command. In 1943, the main runway was extended and acquired an unusual characteristic in that it crossed an active railway line. Rules were put in place giving trains the right of way over landing aircraft. Post-war The airfield was closed at the end of the Second World War, but re-opened in 1947 as the home of the Joint Anti-Submarine School RAF, a training flight flying Avro Shackleton aircraft, which had formed at Lond ...

Ensign Of The Royal Air Force
An ensign is the national flag flown on a vessel to indicate nationality. The ensign is the largest flag, generally flown at the stern (rear) of the ship while in port. The naval ensign (also known as war ensign), used on warships, may be different from the civil ensign (merchant ships) or the yacht ensign (recreational boats). Large versions of naval ensigns called battle ensigns are used when a warship goes into battle. The ensign differs from the jack, which is flown from a jackstaff at the bow of a vessel. In its widest sense, an ensign is just a flag or other standard. The European military rank of ensign, once responsible for bearing a unit's standard (whether national or regimental), derives from it (in the cavalry, the equivalent rank was cornet, named after a type of flag). Ensigns, such as the ancient Roman ensigns in the Arch of Constantine, are not always flags. National ensigns In nautical use, the ensign is flown on a ship or boat to indicate its organiz ...

Antrim, County Antrim
Antrim ( ga, Aontroim , meaning 'lone ridge') is a town and civil parish in County Antrim in the northeast of Northern Ireland, on the banks of the Six Mile Water, on the northeast shore of Lough Neagh. It had a population of 23,375 people in the 2011 Census. It is the county town of County Antrim and was the administrative centre of Antrim Borough Council. It is northwest of Belfast. History Middle Ages According to tradition, a monastery was founded at Antrim in AD 495, thirty years after the death of Saint Patrick, to take forward his ministry, with a small settlement growing up around it. The round tower (see below), also known as "the Steeple", is all that remains. The original name of Antrim was ''Aontreibh'', Irish for 'lone house', referring to the monks' house. This later became, or was reinterpreted, as ''Aontroim'' ('lone ridge'). In the early Middle Ages, the area was part of the Gaelic territory of Dál nAraidi, Dál Araide, which covered much of what is now Co ...

RAF Kinloss
Royal Air Force Kinloss or RAF Kinloss is a former Royal Air Force (RAF) station located near the village of Kinloss, on the Moray Firth in the north east of Scotland. The RAF station opened on 1 April 1939 and served as a training establishment during the Second World War. After the war it was handed over to Coastal Command to monitor Soviet ships and submarines in the Norwegian Sea. Until 2010 it was the main base for the RAF's fleet of Nimrod MR2 maritime patrol aircraft. It was intended that the MR2 would be replaced by the Nimrod MRA4, but the MRA4 was cancelled in the Strategic Defence and Security Review of October 2010. As a result, Kinloss became surplus to RAF requirements and regular flying operations ceased on 31 July 2011. In November 2011, the Ministry of Defence and 12 (Air Support) Engineer Group of the British Army announced that 930 personnel from 39 Engineer Regiment (Air Support) would move from Waterbeach Barracks, near Cambridge, to Kinloss in summ ...

Search And Rescue
Search and rescue (SAR) is the search for and provision of aid to people who are in distress or imminent danger. The general field of search and rescue includes many specialty sub-fields, typically determined by the type of terrain the search is conducted over. These include mountain rescue; ground search and rescue, including the use of search and rescue dogs; urban search and rescue in cities; combat search and rescue on the battlefield and air-sea rescue over water. International Search and Rescue Advisory Group (INSARAG) is a UN organization that promotes the exchange of information between national urban search and rescue organizations. The duty to render assistance is covered by Article 98 of the UNCLOS. Definitions There are many different definitions of search and rescue, depending on the agency involved and country in question. *Canadian Forces: "Search and Rescue comprises the search for, and provision of aid to, persons, ships or other craft which are, or a ...

Anti-submarine Warfare
Anti-submarine warfare (ASW, or in older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades. Successful ASW operations typically involved a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Kiritimati
Kiritimati (also known as Christmas Island) is a Pacific Ocean atoll in the northern Line Islands. It is part of the Republic of Kiribati. The name is derived from the English word "Christmas" written in Gilbertese according to its phonology, in which the combination ''ti'' is pronounced ''s'', giving kiˈrɪsmæs. Kiritimati has the greatest land area of any atoll in the world, about ; its lagoon is roughly the same size. The atoll is about in perimeter, while the lagoon shoreline extends for over . Kiritimati comprises over 70% of the total land area of Kiribati, a country encompassing 33 Pacific atolls and islands. It lies north of the equator, south of Honolulu, and from San Francisco. Kiritimati is in the world's farthest forward time zone, UTC+14, and is therefore one of the first inhabited places on Earth to experience New Year's Day. (see also Caroline Atoll, Kiribati). Although it lies east of the 180th meridian, the Republic of Kiribati realigned the Inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Weapon
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions ( thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been d ...

Operation Grapple
Operation Grapple was a set of four series of British nuclear weapons tests of early atomic bombs and hydrogen bombs carried out in 1957 and 1958 at Malden Island and Kiritimati (Christmas Island) in the Gilbert and Ellice Islands in the Pacific Ocean (modern Kiribati) as part of the British hydrogen bomb programme. Nine nuclear explosions were initiated, culminating in the United Kingdom becoming the third recognised possessor of thermonuclear weapons, and the restoration of the nuclear Special Relationship with the United States in the form of the 1958 US–UK Mutual Defence Agreement. During the Second World War, Britain had a nuclear weapons project, codenamed Tube Alloys, which was merged with the American Manhattan Project in August 1943. Many of Britain's top scientists participated in the Manhattan Project. After the war, fearing that Britain would lose its great power status, the British government resumed the atomic bomb development effort, now codenamed Hig ...

Douglas C-47 Skytrain
The Douglas C-47 Skytrain or Dakota ( RAF, RAAF, RCAF, RNZAF, and SAAF designation) is a military transport aircraft developed from the civilian Douglas DC-3 airliner. It was used extensively by the Allies during World War II and remained in front-line service with various military operators for many years.Parker 2013, pp. 13, 35, 37, 39, 45-47. Design and development The C-47 differed from the civilian DC-3 by way of numerous modifications, including being fitted with a cargo door, hoist attachment and strengthened floor - along with a shortened tail cone for glider-towing shackles, and an astrodome in the cabin roof.Wilson, Stewart. ''Aircraft of WWII''. Fyshwick, ACT, Australia: Aerospace Publications Pty Ltd., 1998. . During World War II, the armed forces of many countries used the C-47 and modified DC-3s for the transport of troops, cargo, and wounded. The U.S. naval designation was R4D. More than 10,000 aircraft were produced in Long Beach and Santa Monica, Califo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed Hudson
The Lockheed Hudson is a light bomber and coastal reconnaissance aircraft built by the American Lockheed Aircraft Corporation. It was initially put into service by the Royal Air Force shortly before the outbreak of the Second World War and primarily operated by it thereafter. The Hudson was a military conversion of the Model 14 Super Electra airliner, and was the first significant aircraft construction contract for Lockheed — the initial RAF order for 200 Hudsons far surpassed any previous order the company had received. The Hudson served throughout the war, mainly with Coastal Command but also in transport and training roles, as well as delivering agents into occupied France. It was also used extensively with the Royal Canadian Air Force's anti-submarine squadrons and by the Royal Australian Air Force. Design and development In late 1937 Lockheed sent a cutaway drawing of the Model 14 to various publications, showing the new aircraft as a civilian aircraft and conv ...
