Avro 730
The Avro 730 was a planned Mach 3 reconnaissance aircraft and strategic bomber that was being developed by Avro Aircraft for the Royal Air Force (RAF). It had been originally envisioned as a very high-speed aircraft to perform aerial reconnaissance missions, conforming with the requirements of Air Ministry Specification OR.330. Avro subsequently decided to modify the design of the proposed 730 in order to accommodate its arming with nuclear weapons; this change therefore meant that the type would be able to perform the nuclear weapons delivery mission as well, which had been called for under Air Ministry Specification RB.156T which sought a high speed reconnaissance-bomber aircraft. If the Avro 730 had proceeded into service, it would have replaced the V bombers as the primary airborne platform as a part of Britain's nuclear deterrent. In early 1957, the Avro 730 was abruptly cancelled, along with the development of a number of other crewed aircraft, as a consequence of the 1 ...

Reconnaissance Aircraft
A reconnaissance aircraft (colloquially, a spy plane) is a military aircraft designed or adapted to perform aerial reconnaissance with roles including collection of imagery intelligence (including using Aerial photography, photography), signals intelligence, as well as measurement and signature intelligence. Modern technology has also enabled some aircraft and Unmanned aerial vehicle, UAVs to carry out real-time surveillance in addition to general Military intelligence, intelligence gathering. Before the development of devices such as radar, military forces relied on reconnaissance aircraft for visual Artillery observer, observation and Reconnaissance, scouting of enemy movement. An example is the Consolidated PBY Catalina, PBY Catalina Maritime patrol aircraft, maritime patrol flying boat used by the Allies of World War II, Allies in World War II: a Formation flying, flight of United States Navy, U.S. Navy Catalinas spotted part of the Japanese fleet approaching Midway Island ...

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 ...

SR-71
The Lockheed SR-71 "Blackbird" is a retired Range (aeronautics), long-range, high-altitude, Mach number, Mach 3+ military strategy, strategic reconnaissance aircraft developed and manufactured by the American aerospace company Lockheed Corporation. Its nicknames include "Common blackbird, Blackbird" and "Protobothrops flavoviridis, Habu". The SR-71 was developed in the 1960s as a black project by Lockheed's Skunk Works division. American aerospace engineer Kelly Johnson (engineer), Clarence "Kelly" Johnson was responsible for many of the SR-71's innovative concepts. Its shape was based on the Lockheed A-12, a pioneer in stealth technology with its reduced radar cross section, but the SR-71 was longer and heavier to carry more fuel and a crew of two in tandem cockpits. The SR-71 was revealed to the public in July 1964 and entered service in the United States Air Force (USAF) in January 1966. During missions, the SR-71 operated at high speeds and altitudes (Mach 3.2 at ... [...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 ...

Interceptor Aircraft
An interceptor aircraft, or simply interceptor, is a type of fighter aircraft designed specifically for the defensive interception role against an attacking enemy aircraft, particularly bombers and reconnaissance aircraft. Aircraft that are capable of being or are employed as both "standard" air superiority fighters and as interceptors are sometimes known as fighter-interceptors. In the post-World War 2 jet age, there are two general classes of interceptor: light fighters, designed for high performance over short range; and heavy fighters, which are intended to operate over longer ranges, in contested airspace and adverse meteorological conditions. While the second type was exemplified historically by specialized night fighter and all-weather interceptor designs, the integration of mid-air refueling, satellite navigation, on-board radar, and beyond visual range (BVR) missile systems since the 1960s has allowed most frontline fighter designs to fill the roles once reserve ...

Soviet Union
The Union of Soviet Socialist Republics. (USSR), commonly known as the Soviet Union, was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 until Dissolution of the Soviet Union, it dissolved in 1991. During its existence, it was the list of countries and dependencies by area, largest country by area, extending across Time in Russia, eleven time zones and sharing Geography of the Soviet Union#Borders and neighbors, borders with twelve countries, and the List of countries and dependencies by population, third-most populous country. An overall successor to the Russian Empire, it was nominally organized as a federal union of Republics of the Soviet Union, national republics, the largest and most populous of which was the Russian SFSR. In practice, Government of the Soviet Union, its government and Economy of the Soviet Union, economy were Soviet-type economic planning, highly centralized. As a one-party state go ...

Operational Requirement
An Operational Requirement, commonly abbreviated OR, was a United Kingdom (UK) Air Ministry document setting out the required characteristics for a future (i.e., as-yet unbuilt) military aircraft or weapon system. The numbered OR would describe what intended role the aircraft would be used for, e.g., bomber, fighter, etc., or what type of weapon was required, e.g., gun, armament, bomb type, etc. In conjunction with any official specification, prospective manufacturers would then choose whether to design an aircraft or weapon for this particular requirement. Operational Requirements were carried over with the dissolution of the Air Ministry and the creation of the Ministry of Defence (MoD). Other requirements An Experimental Requirement (ER) was for an aircraft for research Research is creative and systematic work undertaken to increase the stock of knowledge. It involves the collection, organization, and analysis of evidence to increase understanding of a topic, ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strategic Reconnaissance
In military operations, military reconnaissance () or scouting is the exploration of an area by military forces to obtain information about enemy forces, the terrain, and civil activities in the area of operations. In military jargon, reconnaissance is abbreviated to ''recce'' (in British, Canadian, Australian English) and to ''recon'' (in American English), both derived from the root word ''reconnoitre'' / ''reconnoitering''. The types of reconnaissance include patrolling the local area of operations and long-range reconnaissance patrols, which are tasks usually realized in the United States of America by U.S. Army Rangers, cavalry scouts, and military intelligence specialists, using navy ships and submarines, reconnaissance aircraft, satellites to collect raw intelligence; and establishing observation posts. Moreover, espionage is different from reconnaissance, because spies work as civilians in enemy territory. Etymology The word is derived from the Middle French word '' ...

Nuclear Deterrence
Deterrence theory refers to the scholarship and practice of how threats of using force by one party can convince another party to refrain from initiating some other course of action. The topic gained increased prominence as a military strategy during the Cold War with regard to the use of nuclear weapons and is related to but distinct from the concept of mutual assured destruction, according to which a full-scale nuclear attack on a power with second-strike capability would devastate both parties. The central problem of deterrence revolves around how to credibly threaten military action or nuclear punishment on the adversary despite its costs to the deterrer. Deterrence in an international relations context is the application of deterrence theory to avoid conflict. Deterrence is widely defined as any use of threats (implicit or explicit) or limited force intended to dissuade an actor from taking an action (i.e. maintain the status quo). Deterrence is unlike compellence, which i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Danube (nuclear Weapon)
Blue Danube was the first operational British nuclear weapon. It also went by a variety of other names, including Smallboy, the Mk.1 Atom Bomb, Special Bomb and OR.1001, a reference to the Operational Requirement it was built to fill. The RAF V bomber force was initially meant to use Blue Danube as their primary armament at a time when the first hydrogen bomb had not been detonated, and the British military planners still believed that an atomic war could be fought and won using atomic bombs of similar yield to the Little Boy, Hiroshima bomb. For that reason the stockpile planned was for up to 800 bombs with nuclear weapon yield, yields of 10-12 kilotons. V-bomber bomb bays were sized to carry Blue Danube, the smallest-size nuclear bomb that was possible to be designed given the technology of the day (1947) when their plans were formulated. Design Initial designs for the Blue Danube warhead were based on research derived from Operation Hurricane, Hurricane, the first British nuc ...

Handley Page Victor
The Handley Page Victor was a British jet-powered strategic bomber developed and produced by Handley Page during the Cold War. It was the third and final ''V bomber'' to be operated by the Royal Air Force (RAF), the other two being the Vickers Valiant and the Avro Vulcan. Entering service in 1958, the Victor was initially developed as part of the United Kingdom's airborne nuclear deterrent, but it was retired from the nuclear mission in 1968, following the discovery of Fatigue (material), fatigue cracks which had been exacerbated by the RAF's adoption of a low-altitude flight profile to avoid Interceptor aircraft, interception, and due to the pending introduction of the Royal Navy's submarine-launched Polaris missile#British Polaris, Polaris missiles in 1969. With the nuclear deterrent mission relinquished to the Royal Navy a large V-bomber fleet could not be justified. A number of Victors were modified for strategic reconnaissance, using a combination of radar, cameras, and ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avro Vulcan
The Avro Vulcan (later Hawker Siddeley Vulcan from July 1963) was a jet-powered, tailless, delta-wing, high-altitude, strategic bomber, which was operated by the Royal Air Force (RAF) from 1956 until 1984. Aircraft manufacturer A.V. Roe and Company ( Avro) designed the Vulcan in response to Specification B.35/46. Of the three V bombers produced, the Vulcan was considered the most technically advanced, and therefore the riskiest option. Several reduced-scale aircraft, designated Avro 707s, were produced to test and refine the delta-wing design principles. The Vulcan B.1 was first delivered to the RAF in 1956; deliveries of the improved Vulcan B.2 started in 1960. The B.2 featured more powerful engines, a larger wing, an improved electrical system, and electronic countermeasures, and many were modified to accept the Blue Steel missile. As a part of the V-force, the Vulcan was the backbone of the United Kingdom's airborne nuclear deterrent during much of the Cold War. A ...
