Vickers Valiant
The Vickers Valiant was a British high-altitude jet bomber designed to carry nuclear weapons, and in the 1950s and 1960s was part of the Royal Air Force's " V bomber" strategic deterrent force. It was developed by Vickers-Armstrongs in response to Specification B.35/46 issued by the Air Ministry for a nuclear-armed jet-powered bomber. The Valiant was the first of the V bombers to become operational, and was followed by the Handley Page Victor and the Avro Vulcan. The Valiant is the only V bomber to have dropped live nuclear weapons (for test purposes).Blackman and Wright 2015, p. 33. In 1956, Valiants operating from Malta flew conventional bombing missions over Egypt for Operation Musketeer during the Suez Crisis. From 1956 until early 1966 the main Valiant force was used in the nuclear deterrence role in the confrontation between NATO and the Warsaw Pact powers. Other squadrons undertook aerial refuelling, aerial reconnaissance and Electronic Warfare. In 1962, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Suez Crisis
The Suez Crisis, also known as the Second Arab–Israeli War, the Tripartite Aggression in the Arab world and the Sinai War in Israel, was a British–French–Israeli invasion of Egypt in 1956. Israel invaded on 29 October, having done so with the primary objective of re-opening the Straits of Tiran and the Gulf of Aqaba as the recent tightening of the eight-year-long Egyptian blockade further prevented Israeli passage. After issuing a joint ultimatum for a ceasefire, the United Kingdom and France joined the Israelis on 5 November, seeking to depose Egyptian president Gamal Abdel Nasser and regain control of the Suez Canal, which Nasser had earlier nationalised by transferring administrative control from the foreign-owned Suez Canal Company to Egypt's new government-owned Suez Canal Authority. Shortly after the invasion began, the three countries came under heavy political pressure from both the United States and the Soviet Union, as well as from the United Nations, even ...

Nuclear Weapons And The United Kingdom
In 1952, the United Kingdom became the third country (after the Nuclear weapons of the United States, United States and the Soviet atomic bomb project, Soviet Union) to develop and test nuclear weapons, and is one of the List of states with nuclear weapons#Recognized nuclear-weapon states, five nuclear-weapon states under the Treaty on the Non-Proliferation of Nuclear Weapons. The UK initiated a nuclear weapons programme, codenamed Tube Alloys, during the Second World War. At the Quebec Conference, 1943, Quebec Conference in August 1943, it was British contribution to the Manhattan Project, merged with the American Manhattan Project. The British government considered nuclear weapons to be a joint discovery, but the American Atomic Energy Act of 1946 (McMahon Act) restricted other countries, including the UK, from access to information about nuclear weapons. Fearing the loss of Britain's great power status, the UK resumed its own project, now codenamed High Explosive Research. O ...

Jet Aircraft
A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by one or more jet engines. Whereas the engines in Propeller (aircraft), propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of sound. Jet aircraft generally cruise most efficiently at about Mach number, Mach 0.8 () and at altitudes around or more. The idea of the jet engine was not new, but the technical problems involved did not begin to be solved until the 1930s. Frank Whittle, an English people, English inventor and RAF officer, began development of a viable jet engine in 1928, and Hans von Ohain in Germany began work independently in the early 1930s. In August 1939 the turbojet powered Heinkel He 178, the world's first jet aircraft, made its first flight. A wide range of different types of jet aircraft exist, both for civilian and military pu ...

Air Staff (United Kingdom)
Air Staff is the body of Royal Air Force officers responsible for the running of the RAF. Generally, the heads of the various departments of the Air Staff formed, together with members of the Air Ministry (the British government department in charge of aviation matters), the Air Council. The Air Staff issued "Targets" (AST) which were a stated requirement for an aircraft to fulfil a role within the RAF. E.g. Air Staff Target 362 was for a trainer aircraft to replace the Folland Gnat, the resulting aircraft was the SEPECAT Jaguar. When a specification moved from the initial requirements to a production contract, it became an Air Staff Requirement (ASR). Composition The Air Staff was composed of several posts. * Chief of the Air Staff * Deputy Chief of the Air Staff (1918-1968/9) * Assistant Chief of the Air Staff – replaced Vice Chief and two Assistant Chief posts * Vice Chief of the Air Staff (1940–1985) * Assistant Chief of the Air Staff (Policy) (? -1985) * Assistant Chief ...

Avro Lancaster
The Avro Lancaster, commonly known as the Lancaster Bomber, is a British World War II, Second World War heavy bomber. It was designed and manufactured by Avro as a contemporary of the Handley Page Halifax, both bombers having been developed to the same specification, as well as the Short Stirling, all three aircraft being four-engined heavy bombers adopted by the Royal Air Force (RAF) during the same era. The Lancaster has its origins in the twin-engine Avro Manchester which had been developed during the late 1930s in response to the Air Ministry List of Air Ministry specifications, Specification P.13/36 for a medium bomber for "world-wide use" which could carry a torpedo internally, and make shallow dive-bombing attacks. Originally developed as an evolution of the Manchester (which had proved troublesome in service and was retired in 1942), the Lancaster was designed by Roy Chadwick and powered by four Rolls-Royce Merlins and in one of the versions, Bristol Hercules engines.

Avro Lincoln
The Avro Type 694 Lincoln is a British four-engined heavy bomber, which maiden flight, first flew on 9 June 1944. Developed from the Avro Lancaster, the first Lincoln variants were initially known as the Lancaster IV and V; these were renamed Lincoln I and II. It was the last reciprocating engine, piston-engined bomber operated by the Royal Air Force (RAF); the later Avro Shackleton, though piston-engined, served in maritime patrol rather than bomber roles. The Lincoln attained operational status in August 1945. It had been initially assigned to units of the Tiger Force (air), Tiger Force, a Commonwealth of Nations, Commonwealth heavy bomber force which had been intended to play a role in the Japan campaign in the closing stages of the World War II, Second World War, but the war ended before the Lincoln could participate. Production of the type proceeded and the type was adopted in quantity, complementing and progressively replacing the Lancaster in RAF service during the late 1 ...

RAF Bomber Command
RAF Bomber Command controlled the Royal Air Force's bomber forces from 1936 to 1968. Along with the United States Army Air Forces, it played the central role in the Strategic bombing during World War II#Europe, strategic bombing of Germany in World War II. From 1942 onward, the British bombing campaign against Germany became Area bombing directive, less restrictive and increasingly targeted industrial sites and the civilian manpower base essential for German war production. In total 501,536 operational sorties were flown, of bombs were dropped and 8,325 aircraft lost in action. Bomber Command crews also suffered a high casualty rate: 55,573 were killed out of a total of 125,000 aircrew, a 44.4% death rate. A further 8,403 men were wounded in action, and 9,838 became prisoners of war. Bomber Command stood at the peak of its post-war Armed forces, military power in the 1960s, the V bombers holding the United Kingdom's nuclear deterrent and a supplemental force of English Electric ...

Henry Tizard
Sir Henry Thomas Tizard (23 August 1885 – 9 October 1959) was an English chemist, inventor and Rector of Imperial College, who developed the modern "octane rating" used to classify petrol, helped develop radar in World War II, and led the first serious studies of Unidentified flying object, UFOs. Life Tizard was born in Gillingham, Kent, Gillingham, Kent in 1885, the only son of Thomas Henry Tizard (1839–1924), naval officer and hydrographer, and his wife, Mary Elizabeth Churchward. His ambition to join the navy was thwarted by poor eyesight, and he instead studied at Westminster School and Magdalen College, Oxford, where he concentrated on mathematics and chemistry, doing work on indicators and the motions of ions in gases. Tizard graduated in 1908 and at his tutor's suggestion, he spent time in Berlin, where he met and formed a close friendship with Frederick Alexander Lindemann, later an influential scientific advisor of Winston Churchill. In 1909, he became a researcher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Surface-to-air Missile
A surface-to-air missile (SAM), also known as a ground-to-air missile (GTAM) or surface-to-air guided weapon (SAGW), is a missile designed to be launched from the ground or the sea to destroy aircraft or other missiles. It is one type of anti-aircraft warfare, anti-aircraft system; in modern armed forces, missiles have replaced most other forms of dedicated anti-aircraft weapons, with anti-aircraft guns pushed into specialized roles. The first attempt at SAM development took place during World War II, but no operational systems were introduced. Further development in the 1940s and 1950s led to operational systems being introduced by most major forces during the second half of the 1950s. Smaller systems, suitable for close-range work, evolved through the 1960s and 1970s, to modern systems that are man-portable. Shipborne systems followed the evolution of land-based models, starting with long-range weapons and steadily evolving toward smaller designs to provide a layered defence. T ...
