The Avro Blue Steel was a British air-launched, rocket-propelled nuclear armed standoff missile, built to arm the V bomber force. It allowed the bomber to launch the missile against its target while still outside the range of surface-to-air missiles (SAMs). The missile proceeded to the target at speeds up to Mach 3, and would trigger within 100 m of the pre-defined target point.
Civil defense or civil protection is an effort to protect the citizens of a state from human-made and natural disasters. It uses the principles of emergency operations: prevention, mitigation, preparation, response, or emergency evacuation and recovery. Programs of this sort were initially discussed at least as early as the 1920s and were implemented in some countries during the 1930s as the threat of war and aerial bombardment grew. Civil-defense structures became widespread after authorities recognised the threats posed by nuclear weapons.
The War Game is a 1966 British pseudo-documentary film that depicts a nuclear war and its aftermath. Written, directed and produced by Peter Watkins for the BBC, it caused dismay within the BBC and also within government, and was subsequently withdrawn before the provisional screening date of 6 October 1965. The corporation said that "the effect of the film has been judged by the BBC to be too horrifying for the medium of broadcasting. It will, however, be shown to invited audiences..."
The Vanguard class is a class of nuclear-powered ballistic missile submarines (SSBNs) in service with the Royal Navy. The class was introduced in 1994 as part of the Trident nuclear programme, and comprises four vessels: Vanguard, Victorious, Vigilant and Vengeance, built between 1986 and 1999 at Barrow-in-Furness by Vickers Shipbuilding and Engineering, now owned by BAE Systems. All four boats are based at HM Naval Base Clyde , 40 km (25 mi) west of Glasgow, Scotland.
The Blitz was a German bombing campaign against the United Kingdom, in 1940 and 1941, during the Second World War. The term was first used by the British press and originated from the term Blitzkrieg, the German word meaning 'lightning war'.
Chevaline was a system to improve the penetrability of the warheads used by the British Polaris nuclear weapons system. Devised as an answer to the improved Soviet anti-ballistic missile defences around Moscow, the system increased the probability that at least one warhead would penetrate Moscow's anti-ballistic missile (ABM) defences, something which the Royal Navy's earlier UGM-27 Polaris re-entry vehicles (RVs) were thought to be unlikely to do.
The Astute class is the latest class of nuclear-powered fleet submarines (SSNs) in service with the Royal Navy. The boats are being constructed by BAE Systems Submarines at Barrow-in-Furness. Seven boats will be constructed: the first of class, Astute, was launched by Camilla, Duchess of Cornwall, in 2007, commissioned in 2010, and declared fully operational in May 2014. The Astute class is the replacement for the Trafalgar-class fleet submarines in Royal Navy service.
The Ministry of Defence is the department responsible for implementing the defence policy set by His Majesty's Government, and is the headquarters of the British Armed Forces.
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 in the Gilbert and Ellice Islands in the Pacific Ocean 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.
Akrotiri and Dhekelia, officially the Sovereign Base Areas of Akrotiri and Dhekelia (SBA), is a British Overseas Territory on the island of Cyprus. The areas, which include British military bases and installations formerly part of the Crown colony of Cyprus, were retained by the British under the 1960 treaty of independence signed by the United Kingdom, Greece, Turkey and representatives from the Greek and Turkish Cypriot communities. The territory serves an important role as a station for signals intelligence and provides a vital strategic part of the United Kingdom surveillance-gathering network in the Mediterranean and the Middle East.
The Boeing Chinook is a large, tandem rotor helicopter operated by the Royal Air Force (RAF). A series of variants based on the United States Army's Boeing CH-47 Chinook, the RAF Chinook fleet is the largest outside the United States. RAF Chinooks have seen extensive service in the Falklands War, the Balkans, Northern Ireland, Iraq, and Afghanistan.
In 1952, the United Kingdom became the third country to develop and test nuclear weapons, and is one of the five nuclear-weapon states under the Treaty on the Non-Proliferation of Nuclear Weapons.
The US–UK Mutual Defense Agreement, or 1958 UK–US Mutual Defence Agreement, is a bilateral treaty between the United States and the United Kingdom on nuclear weapons co-operation. The treaty's full name is Agreement between the Government of the United States of America and the Government of the United Kingdom of Great Britain and Northern Ireland for Cooperation on the uses of Atomic Energy for Mutual Defense Purposes. It allows the US and the UK to exchange nuclear materials, technology and information. The US has nuclear co-operation agreements with other countries, including France and other NATO countries, but this agreement is by far the most comprehensive. Because of the agreement's strategic value to Britain, Harold Macmillan called it "the Great Prize".
The Dreadnought class is the future replacement for the Vanguard class of ballistic missile submarines. Like their predecessors they will carry Trident II D-5 missiles. The Vanguard submarines entered service in the United Kingdom in the 1990s with an intended service life of 25 years. Their replacement is necessary if the Royal Navy is to maintain a continuous at-sea deterrent (CASD), the principle of operation behind the Trident system.
Trident, also known as the Trident nuclear programme or Trident nuclear deterrent, covers the development, procurement and operation of nuclear weapons in the United Kingdom and their means of delivery. Its purpose as stated by the Ministry of Defence is to "deter the most extreme threats to our national security and way of life, which cannot be done by other means". Trident is an operational system of four Vanguard-class submarines armed with Trident II D-5 ballistic missiles, able to deliver thermonuclear warheads from multiple independently targetable re-entry vehicles (MIRVs). It is operated by the Royal Navy and based at Clyde Naval Base on the west coast of Scotland. At least one submarine is always on patrol to provide a continuous at-sea capability. The missiles are manufactured in the United States, while the warheads are British.
The Battle of Musa Qala was a British-led military action in Helmand Province, southern Afghanistan, launched by the Afghan National Army and the International Security Assistance Force (ISAF) against the Taliban on 7 December 2007. After three days of intense fighting, the Taliban retreated into the mountains on 10 December. Musa Qala was officially reported captured on 12 December, with Afghan Army troops pushing into the town centre.
Iron Dome is a mobile all-weather air defense system developed by Rafael Advanced Defense Systems and Israel Aerospace Industries. The system is designed to intercept and destroy short-range rockets and artillery shells fired from distances of 4 kilometres (2.5 mi) to 70 kilometres (43 mi) away and whose trajectory would take them to an Israeli populated area. From 2011 to 2021, the United States contributed a total of US$1.6 billion to the Iron Dome defense system, with another US$1 billion approved by the US Congress in 2022.
Following the success of Operation Grapple in which the United Kingdom became the third nation to acquire thermonuclear weapons after the United States and the Soviet Union, Britain launched negotiations with the US on a treaty under in which both could share information and material to design, test and maintain their nuclear weapons. This effort culminated in the 1958 US–UK Mutual Defence Agreement. One of the results of that treaty was that Britain was allowed to use United States' Nevada Test Site for testing their designs and ideas, and received full support from the personnel there, in exchange for the data "take" from the experiment, a mutual condition. In effect the Nevada Test Site became Britain's test ground, subject only to advance planning and integrating their testing into that of the United States. This resulted in 24 underground tests at the Nevada Test Site from 1958 through the end of nuclear testing in the US in September 1992.
The British hydrogen bomb programme was the ultimately successful British effort to develop hydrogen bombs between 1952 and 1958. During the early part of the Second World War, Britain had a nuclear weapons project, codenamed Tube Alloys. At the Quebec Conference in August 1943, British prime minister Winston Churchill and United States president Franklin Roosevelt signed the Quebec Agreement, merging Tube Alloys into the American Manhattan Project, in which many of Britain's top scientists participated. The British government trusted that America would share nuclear technology, which it considered to be a joint discovery, but the United States Atomic Energy Act of 1946 ended technical cooperation. Fearing a resurgence of American isolationism, and the loss of Britain's great power status, the British government resumed its own development effort, which was codenamed "High Explosive Research".
Violet Friend was the Ministry of Supply rainbow code for an anti-ballistic missile (ABM) system developed in the United Kingdom. The project began in 1954 with study contracts for an early warning radar system, which was followed by the February 1955 release of Air Staff Target 1135 (AST.1135) calling for a system to counter intermediate range ballistic missiles (IRBMs) being fired at the UK from eastern Europe. AST.1135 required the system to be able to attack six targets at once and be ready for initial deployment in 1963.
