A light bomber is a relatively small and fast type of military bomber aircraft that was primarily employed before the 1950s. Such aircraft would typically not carry more than one ton of ordnance .
166-624: The British Aircraft Corporation TSR-2 is a cancelled Cold War strike and reconnaissance aircraft developed by the British Aircraft Corporation (BAC), for the Royal Air Force (RAF) in the late 1950s and early 1960s. The TSR-2 was designed around both conventional and nuclear weapons delivery : it was to penetrate well-defended frontline areas at low altitudes and very high speeds, and then attack high-value targets in rear areas. Another intended combat role
332-410: A circular error probable of 1,200 ft (370 m) and a damage probability of 0.8, and laydown delivery capability, with burst heights for targets from 0 to 10,000 ft (3,000 m) above sea level. Other requirements were a weight of up to 1,000 lb (450 kg), a length of up to 144 in (3.7 m), and a diameter up to 28 in (710 mm) (the same as Red Beard). However,
498-486: A light bomber . The Javelin had an advanced (for the era) navigation system that would be useful in this role. This led to operational requirement OR.328, but this was ultimately rejected as the range was far too short when flown at low altitude. Shortly thereafter, English Electric began work on Royal Navy requirement for a low-altitude strike aircraft , which would ultimately be won by Blackburn with their Buccaneer . With minor changes, EE submitted their Navy entry to

Later variants of the Ju 87 Stuka dive bomber were adapted to the role of ground attack against tanks armed with 37 mm cannon , and the Curtiss SB2C Helldiver (a U.S. Navy dive bomber adopted later in World War II when that design role was beginning to disappear) also was assigned to ground attack sorties using its cannon , bombs and rockets . The light bomber, as

A crew of two was required, one being the operator of the advanced navigational and attack equipment. The bombload was to be four 1,000 lb (450 kg) bombs. The requirements were eventually made official in November 1956 with General Operational Requirement 339 (GOR.339), which
996-804: A German rebuilding effort set forth by western European countries in 1948, the US, Britain and France spearheaded the establishment of the Federal Republic of Germany from the three Western zones of occupation in April 1949. The Soviet Union proclaimed its zone of occupation in Germany the German Democratic Republic that October. Media in the Eastern Bloc was an organ of the state , completely reliant on and subservient to
1162-626: A bomb load of 50–400 kg. Two of the most famous were the Airco DH.4 designed by Geoffrey de Havilland , and the Breguet 14 designed by Louis Breguet . The same type often also served as reconnaissance aircraft; examples include the Albatros C.III , Avro 504 , DFW C.V , LVG C.II , Royal Aircraft Factory R.E.8 , Rumpler C.I and Voisin III . The Royal Aircraft Factory B.E.2 was even modified as
1328-462: A development batch of nine airframes, to be built using production jigs. The choice of proceeding to production tooling turned out to be another source of delay, with the first aircraft having to adhere to strict production standards or deal with the bureaucracy of attaining concessions to allow them to exhibit differences from later airframes. Four years into the project, the first few airframes had effectively become prototypes in all but name, exhibiting
1494-575: A discrete aircraft type, began to be superseded as World War II opened. The growth of engine power from the 1,000 hp to the 2,000 hp class during the war produced single-engine fighters with greater performance, offensive and defensive capabilities than the light bombers of only a few years earlier. This gave rise to the fighter-bomber type, notably the Fw 190 F and G models, Hawker Typhoon and Republic P-47 Thunderbolt . Multirole twin-engine designs capable of hauling bomb loads greater than 2,000 lbs such as
1660-639: A few years). During the early stages of World War II , the above-mentioned designs of the late 1930s often saw considerable action. In some cases, they became the basis of newer, faster light bombers, such as the Martin Baltimore ( U.S. designation A-23/A-30 developed from the Maryland), as well as medium bombers with more powerful engines and heavier payloads . Twin-engine light bombers were successful when converted into airborne radar -equipped night fighters during World War II; examples include
1826-646: A general term, in his essay "You and the Atomic Bomb", published 19 October 1945 in the British newspaper Tribune . Contemplating a world living in the shadow of the threat of nuclear warfare , Orwell looked at James Burnham 's predictions of a polarized world, writing: Looking at the world as a whole, the drift for many decades has been not towards anarchy but towards the reimposition of slavery... James Burnham's theory has been much discussed, but few people have yet considered its ideological implications—that is,

#17327717929651992-405: A ground-based interception of low-flying aircraft extremely difficult. The Canberra was designed for medium- to high-altitude flight and was not suitable for continuous terrain-hugging flight; this would require a completely different aircraft. Low-level strike aircraft, or " interdictors ", grew into a new class of their own during the late 1950s. They generally featured high wing loading to reduce
2158-502: A huge advantage in practical terms. Hawker-Siddeley, parent of Hawker, Avro and Gloster, had entered five designs. This led to some confusion and internal dissent within the company. Avro, having lost the Avro 730 project, felt that a new bomber design was naturally theirs to lead. Gloster's design remained based on Javelin, and on 11 December 1957, the Hawker design team stated flatly there
2324-477: A jet-powered version would be even more difficult to intercept. This led to Air Ministry specification E.3/45. The winning design, the English Electric Canberra , also dispensed with defensive armament, producing a design with the speed and altitude that allowed it to fly past most defences. The design's large wings gave it the lift needed to operate at very high altitudes, placing it above

Radio Free Europe attempted to achieve these goals by serving as a surrogate home radio station, an alternative to the controlled and party-dominated domestic press in the Soviet Bloc. Radio Free Europe was a product of some of

Conservative Member of Parliament and former Minister for Aviation Julian Amery writing in Sunday Telegraph 1965 As this specification was being studied by various manufacturers, the first of the political storms that were to dog the project reared its head, when Defence Minister Duncan Sandys stated in the 1957 Defence White Paper that
2822-518: A ministerial ruling on 9 July 1962 decreed that all future tactical nuclear weapons should be limited to a yield of 10 kt. The RAF issued a new version of the OR.1177 specification, accepting the lower yield, while making provision in the design for it to be capable of adaptation later for a higher yield, in the event of the political restriction being lifted. Meanwhile, the RAF explored ways of compensating for

3154-675: A new war". On 6 September 1946, James F. Byrnes delivered a speech in Germany repudiating the Morgenthau Plan (a proposal to partition and de-industrialize post-war Germany) and warning the Soviets that the US intended to maintain a military presence in Europe indefinitely. As Byrnes stated a month later, "The nub of our program was to win the German people ... it was a battle between us and Russia over minds ..." In December,
3320-704: A nuclear weapon. There had been some interest in the TSR-2 from Australia for the Royal Australian Air Force (RAAF), but in 1963, the RAAF chose to buy the F-111 instead, having been offered a better price and delivery schedule by the American manufacturer. Nonetheless, the RAAF had to wait 10 years before the F-111 was ready to enter service, by which time the anticipated programme cost had tripled. The RAF
3486-493: A nuclear weapons role. On 1 January 1959, the project was given an official go-ahead; in February, it came under the new designation Operational Requirement 343. OR.343 was more specific and built upon work from the various submissions to GOR.339 specifically stating that the low-level operations would be at 200 ft (61 m) or less, and that Mach 2 should be attained at altitude.

#17327717929653652-529: A pioneering night fighter in attempts to shoot down German Zeppelins . By the early 1930s many air forces were seeking to replace their older biplane aircraft (for example, the RAF 's Hawker Hart and VVS 's Polikarpov R-5 ) with more modern and higher performance monoplane designs. Specialised light bomber designs were single-engine or twin-engine aircraft with a bomb load of about 500–1,000 kg. Typical single-engine light bombers of this era included
3818-710: A plan envisioning an economically self-sufficient Germany, including a detailed accounting of the industrial plants, goods and infrastructure already taken by the Soviets. In June 1947, in accordance with the Truman Doctrine , the United States enacted the Marshall Plan , a pledge of economic assistance for all European countries willing to participate, including the Soviet Union. Under the plan, which President Harry S. Truman signed on 3 April 1948,
3984-458: A refined version of GOR.339. Hawker submitted their updated "P.1129 Development", while minor variations of the other two designs were offered. Given the similarities between the Vickers and EE, there was some discussion of awarding another series of proposals, one from Vickers and EE and the other from Hawker-Siddeley, but it was noted this would delay the final contract by as much as a year. It
4150-629: A secret 1950 document, the National Security Council proposed reinforcing pro-Western alliance systems and quadrupling spending on defense. Truman, under the influence of advisor Paul Nitze , saw containment as implying complete rollback of Soviet influence in all its forms. United States officials moved to expand this version of containment into Asia , Africa , and Latin America , in order to counter revolutionary nationalist movements, often led by communist parties financed by
4316-491: A self-defense measure; even the bomb load was minimised towards this design goal. Early examples were the Bristol Blenheim and Dornier Do 17 (both introduced in 1937). A weakness of the fast bomber design concept was that improvements in the speed of bombers were, in most cases, quickly matched in subsequent fighter designs (which would additionally eclipse the load -carrying ability of light bomber aircraft within
4482-511: A similar bomb load as the Invader) medium bomber. The substantial increases in performance, load -carrying ability, and multirole versatility of new combat aircraft designs (including the advent of jet aircraft ) by the end of World War II signaled the end of the dedicated light bomber type. Attack aircraft , strike fighters , counter-insurgency aircraft and combat UAVs are types which today carry out technologically enhanced equivalents of

On flying the TSR-2 himself, Dell described the prototype as handling "like a big Lightning". Over a period of six months,
4814-480: A source of intelligence. During the late 1970s and 1980s, the KGB perfected its use of espionage to sway and distort diplomacy. Active measures were "clandestine operations designed to further Soviet foreign policy goals," consisting of disinformation, forgeries, leaks to foreign media, and the channeling of aid to militant groups. Retired KGB Major General Oleg Kalugin , former head of Foreign Counter Intelligence for

Despite the increasing costs the first two of the development batch aircraft were completed. Engine development and undercarriage problems led to delays for the first flight which meant that the TSR-2 missed the opportunity to be displayed to the public at 1964's Farnborough Airshow . In

In the 1980s, the US provided support for anti-communist forces in Africa, Asia, and Latin America, and the leadership of the USSR changed with the rise of Mikhail Gorbachev , who expanded political freedoms in his country and the Eastern Bloc. This led to

5312-494: A total of 24 test flights were conducted. Most of the complex electronics were not fitted to the first aircraft, so these flights were all concerned with the basic flying qualities of the aircraft which, according to the test pilots involved, were outstanding. Speeds of Mach 1.12 and sustained low-level flights down to 200 ft were achieved above the Pennines . Undercarriage vibration problems continued, however, and only in

Approval for high-yield tactical weapons was eventually gained in 1970 and, by 1975, the RAF had WE.177C, which at almost 200 kt was a weapon very similar to what they had planned for the TSR-2 in 1959. Throughout 1959, English Electric (EE) and Vickers worked on combining the best of both designs in order to put forward a joint design with

A week later, on 13 March, Stalin responded vigorously to the speech, saying Churchill could be compared to Adolf Hitler insofar as he advocated the racial superiority of English-speaking nations so that they could satisfy their hunger for world domination, and that such a declaration was "a call for war on the USSR." The Soviet leader also dismissed

Many other aircraft which originally had been designed as fighters or other mission-specific bombers but fit the size, performance and payload requirements for the light bomber role would also be adapted to perform such missions during World War II. Most dive bombers , such as the Junkers Ju 87 Stuka and Vultee Vengeance were light bombers by definition, as these aircraft typically carried bomb loads of one ton or less. Likewise, many torpedo bombers were light bombers according to their size and warload and it

The Mosquito had been designed with the express intent of reducing the weight of the aircraft in order to improve its speed as much as possible. This process led to the removal of all defensive armament, improving performance to the point where it was unnecessary anyway. This high-speed approach was extremely successful, and

12284-555: The Soviet S-75 Dvina ( NATO name "SA-2 Guideline") SAM was a Taiwanese RB-57 , a US reconnaissance version of the Canberra, shot down in 1959. The solution was to fly lower: since radar operates in line-of-sight , the curvature of the Earth renders low-flying aircraft invisible beyond a certain range, the radar horizon . In practice, trees, hills, valleys and any other obstructions reduce this range even more, making
12450-481: The Soviet Union and its communist party , which had an influence across the Second World and was also tied to a network of authoritarian states. The Soviet Union had a command economy and installed similarly communist regimes its in satellites. United States involvement in regime change during the Cold War included support for anti-communist and right-wing dictatorships , governments, and uprisings across
12616-467: The Soviet Union was used to monitor dissent from official Soviet politics and morals. Although to an extent disinformation had always existed, the term itself was invented, and the strategy formalized by a black propaganda department of the Soviet KGB. Based on the amount of top-secret Cold War archival information that has been released, historian Raymond L. Garthoff concludes there probably
12782-572: The Soviet Union, which at the time was undergoing the Era of Stagnation . This phase saw the new Soviet leader Mikhail Gorbachev introducing the liberalizing reforms of glasnost ("openness") and perestroika ("reorganization") and ending Soviet involvement in Afghanistan in 1989. Pressures for national sovereignty grew stronger in Eastern Europe, and Gorbachev refused to further support
12948-558: The Soviet Union. A number of self-proclaimed Marxist–Leninist governments were formed in the second half of the 1970s in developing countries , including Angola , Mozambique , Ethiopia , Cambodia , Afghanistan , and Nicaragua . Détente collapsed at the end of the decade with the beginning of the Soviet–Afghan War in 1979. Beginning in the 1980s, this phase was another period of elevated tension. The Reagan Doctrine led to increased diplomatic, military, and economic pressures on
13114-643: The Soviets accumulated after broken promises by Stalin and Molotov concerning Europe and Iran. Following the World War II Anglo-Soviet invasion of Iran , the country was occupied by the Red Army in the far north and the British in the south. Iran was used by the United States and British to supply the Soviet Union, and the Allies agreed to withdraw from Iran within six months after the cessation of hostilities. However, when this deadline came,
13280-535: The Soviets agreed to withdraw from Iran after persistent US pressure, an early success of containment policy. By 1947, US president Harry S. Truman was outraged by the perceived resistance of the Soviet Union to American demands in Iran, Turkey, and Greece, as well as Soviet rejection of the Baruch Plan on nuclear weapons. In February 1947, the British government announced that it could no longer afford to finance
13446-622: The Soviets had permitted to retain democratic structures. The public brutality of the coup shocked Western powers more than any event up to that point, set in motion a brief scare that war would occur, and swept away the last vestiges of opposition to the Marshall Plan in the United States Congress. In an immediate aftermath of the crisis, the London Six-Power Conference was held, resulting in
13612-545: The Soviets remained in Iran under the guise of the Azerbaijan People's Government and Kurdish Republic of Mahabad . Shortly thereafter, on 5 March, former British prime minister Winston Churchill delivered his famous " Iron Curtain " speech in Fulton, Missouri . The speech called for an Anglo-American alliance against the Soviets, whom he accused of establishing an "iron curtain" dividing Europe from " Stettin in
13778-510: The TSR-2 bomb bay (originally designed to accommodate a single Red Beard weapon) necessitating the reduction in diameter of the WE.177A to 16.5 in (42 cm), the bomb's width and fin span being constrained by the need to fit two WE.177 bombs side-by-side in the aircraft's bomb bay. The requirement for stick bombing using nuclear weapons was soon dropped as larger yield bombs came back into favour. A drawback of carrying WE.177 on external pylons
13944-539: The TSR-2 early in development but not proceeded with. These included an air-launched development of the Blue Water missile, carried underwing, or semi-recessed in the bomb bay, and an air-launched ballistic missile , referred to as Grand Slam , with a warhead derived from that intended for the Skybolt missile, and a range of 100 nmi (120 mi; 190 km). Conventional missiles were catered for instead, with
14110-402: The TSR-2 procurement process. Eventually, the smaller swing-wing Panavia Tornado was developed and adopted by a European consortium to fulfil broadly similar requirements to the TSR-2. The introduction of the first jet engines in the late- World War II period led to calls for new jet-powered versions of practically every aircraft then flying. Among these was the design of a replacement for
14276-421: The TSR-2 was to carry a 2,000 lb (910 kg) weapon internally for a combat radius of 1,000 nautical miles (1,200 mi; 1,900 km). Of that mission 100 nautical miles (120 mi; 190 km) was to be flown at higher altitudes at Mach 1.7 and the 200 nmi (230 mi; 370 km) into and out of the target area was to be flown as low as 200 ft at a speed of Mach 0.95. The remainder of
14442-634: The TSR-2's supersonic flying characteristics to the Canberra's own subsonic flight characteristics, stating that the Canberra was more troublesome. According to the Flight Envelope diagram, TSR2 was capable of sustained cruise at Mach 2.05 at altitudes between 37,000 ft (11,000 m) and 51,000 ft (16,000 m) and had a dash speed of Mach 2.35 (with a limiting leading edge temperature of 140 °C). The aircraft featured some extremely sophisticated avionics for navigation and mission delivery, which would also prove to be one of
14608-520: The Truman Doctrine marked the beginning of a US bipartisan defense and foreign policy consensus between Republicans and Democrats focused on containment and deterrence that weakened during and after the Vietnam War , but ultimately persisted thereafter. Moderate and conservative parties in Europe, as well as social democrats, gave virtually unconditional support to the Western alliance, while European and American Communists , financed by
14774-567: The US assistance, the Greek military won its civil war . Under the leadership of Alcide De Gasperi the Italian Christian Democrats defeated the powerful Communist – Socialist alliance in the elections of 1948 . All major powers engaged in espionage, using a great variety of spies, double agents , moles , and new technologies such as the tapping of telephone cables. The Soviet KGB ("Committee for State Security"),
14940-581: The US government gave to Western European countries over $ 13 billion (equivalent to $ 189 billion in 2016) to rebuild the economy of Europe . Later, the program led to the creation of the OECD . The plan's aim was to rebuild the democratic and economic systems of Europe and to counter perceived threats to the European balance of power , such as communist parties seizing control through revolutions or elections. The plan also stated that European prosperity
15106-588: The US was trying to buy a pro-US re-alignment of Europe. Stalin therefore prevented Eastern Bloc nations from receiving Marshall Plan aid. The Soviet Union's alternative to the Marshall Plan, which was purported to involve Soviet subsidies and trade with central and eastern Europe, became known as the Molotov Plan (later institutionalized in January 1949 as the Council for Mutual Economic Assistance ). Stalin
15272-483: The USSR. In this way, this US would exercise " preponderant power ," oppose neutrality, and establish global hegemony . In the early 1950s (a period sometimes known as the " Pactomania "), the US formalized a series of alliances with Japan (a former WWII enemy), South Korea , Taiwan , Australia , New Zealand , Thailand and the Philippines (notably ANZUS in 1951 and SEATO in 1954), thereby guaranteeing
15438-527: The United Nations, was split up and dissolved in 1954 and 1975, also because of the détente between the West and Tito. The US and Britain merged their western German occupation zones into " Bizone " (1 January 1947, later "Trizone" with the addition of France's zone, April 1949). As part of the economic rebuilding of Germany, in early 1948, representatives of a number of Western European governments and
15604-518: The United States a number of long-term military bases. One of the more significant examples of the implementation of containment was the United Nations US-led intervention in the Korean War . In June 1950, after years of mutual hostilities, Kim Il Sung 's North Korean People's Army invaded South Korea at the 38th parallel . Stalin had been reluctant to support the invasion but ultimately sent advisers. To Stalin's surprise,
15770-401: The United States announced an agreement for a merger of western German areas into a federal governmental system. In addition, in accordance with the Marshall Plan , they began to re-industrialize and rebuild the West German economy, including the introduction of a new Deutsche Mark currency to replace the old Reichsmark currency that the Soviets had debased. The US had secretly decided that
15936-679: The United States. Light bomber The earliest light bombers were intended to drop their bombs in level flight over a target. During World War I some air forces began to distinguish between light bombers and the earliest purpose-built attack aircraft which carried out ground attack, close air support , anti-shipping and similar missions. After World War I, attack aircraft were typically identifiable by their ability to carry multiple fixed machine guns , automatic cannons and rockets in addition to bombs . Light bombers have often served as attack aircraft and vice versa. Purpose-built light bombers disappeared from military aviation by
16102-510: The Warsaw Pact's primary function was to safeguard Soviet hegemony over its Eastern European satellites, with the pact's only direct military actions having been the invasions of its own member states to keep them from breaking away; in the 1960s, the pact evolved into a multilateral alliance, in which the non-Soviet Warsaw Pact members gained significant scope to pursue their own interests. In 1961, Soviet-allied East Germany constructed
16268-472: The Western agencies paid special attention to debriefing Eastern Bloc defectors . Edward Jay Epstein describes that the CIA understood that the KGB used "provocations", or fake defections, as a trick to embarrass Western intelligence and establish Soviet double agents. As a result, from 1959 to 1973, the CIA required that East Bloc defectors went through a counterintelligence investigation before being recruited as
16434-462: The accusation that the USSR was exerting increasing control over the countries lying in its sphere. He argued that there was nothing surprising in "the fact that the Soviet Union, anxious for its future safety, [was] trying to see to it that governments loyal in their attitude to the Soviet Union should exist in these countries." Soviet territorial demands to Turkey regarding the Dardanelles in
16600-414: The airframe would be capable of accomplishing the tasks set for it and that it represented a major advance on any other type." Costs continued to rise, which led to concerns at both company and government upper management levels, and the aircraft was also falling short of many of the requirements laid out in OR.343, such as takeoff distance and combat radius. As a cost-saving measure, a reduced specification
16766-561: The allocation of $ 400 million to intervene in the war and unveiled the Truman Doctrine , which framed the conflict as a contest between free peoples and totalitarian regimes. American policymakers accused the Soviet Union of conspiring against the Greek royalists in an effort to expand Soviet influence even though Stalin had told the Communist Party to cooperate with the British-backed government. Enunciation of
16932-537: The argument over the need for manned aircraft, additional political machinations had the effect of complicating the project. In September 1957 the Ministry of Supply informed the heads of the aviation companies that the only acceptable proposals would be those issued from teams consisting of more than one company. There was a large number of competing aircraft manufacturing companies in the UK, while orders were decreasing; thus
17098-426: The bureau responsible for foreign espionage and internal surveillance, was famous for its effectiveness. The most famous Soviet operation involved its atomic spies that delivered crucial information from the United States' Manhattan Project , leading the USSR to detonate its first nuclear weapon in 1949, four years after the American detonation and much sooner than expected. A massive network of informants throughout
17264-716: The chancellor of West Germany, with France the main opponent. Washington had the decisive voice. It was strongly supported by the Pentagon (the US military leadership), and weakly opposed by President Truman; the State Department was ambivalent. The outbreak of the Korean War in June 1950 changed the calculations and Washington now gave full support. That also involved naming Dwight D. Eisenhower in charge of NATO forces and sending more American troops to West Germany. There
17430-515: The communist party. Radio and television organizations were state-owned, while print media was usually owned by political organizations, mostly by the local communist party. Soviet radio broadcasts used Marxist rhetoric to attack capitalism, emphasizing themes of labor exploitation, imperialism and war-mongering. Along with the broadcasts of the BBC and the Voice of America to Central and Eastern Europe,
17596-497: The country and was banned following the 1991 Soviet coup attempt that August. This in turn led to the formal dissolution of the Soviet Union in December 1991 and the collapse of Communist governments across much of Africa and Asia. The Russian Federation became the Soviet Union's successor state, while many of the other republics emerged from the Soviet Union's collapse as fully independent post-Soviet states . The United States
17762-678: The days leading up to the testing, Denis Healey , the Opposition shadow secretary for defence , had criticised the aircraft saying that by the time it was introduced it would face "new anti-aircraft" missiles that would shoot it down making it prohibitively expensive at £16 million per aircraft (on the basis of only 30 ordered). Test pilot Roland Beamont finally made the first flight from the Aeroplane and Armament Experimental Establishment (A&AEE) at Boscombe Down , Wiltshire, on 27 September 1964. Initial flight tests were all performed with
17928-673: The decision in a debate in the House of Commons , saying that the F-111 would prove cheaper. Cold War The Cold War was a period of global geopolitical tension and struggle for ideological and economic influence between the United States and the Soviet Union (USSR) and their respective allies, the Western Bloc and the Eastern Bloc , that started in 1947, two years after the end of World War II , and lasted until
18094-604: The design originally centring on use of the AGM-12 Bullpup , then moving on to favour the French AS-30 before settling on the new OR.1168 missile (which would become the TV-guided AJ-168 Martel ). After the cancellation of the TSR-2, the RAF eventually filled the tactical strike requirement using McDonnell F-4 Phantom IIs with US dual-key nuclear weapons , but continued their attempts to get
18260-668: The desired role. As one RAF official put it, "If we show the slightest interest in NA.39 we might not get the GOR.339 aircraft." Another political opponent of the TSR-2 project was Sir Solly Zuckerman , at the time the Chief Scientific Advisor to the Ministry of Defence. Zuckerman had a low opinion of British technological achievements and was in favour of procuring military hardware from the United States. English Electric and Hawker Aircraft had already received some signals from
18426-506: The effects of turbulence and cross-wind, some form of high-performance terrain-following radar to allow very low flight at high speeds, and large fuel loads to offset the higher fuel use at low altitudes. Aware of the changing operational environment, the Ministry of Supply started work with English Electric in 1955, attempting to define a new light bomber to replace the Canberra. These early studies eventually settled on an aircraft with
18592-486: The end of World War II, as advancements in propulsion and aeronautical design enabled newer attack/strike aircraft, fighter-bombers , and multirole aircraft types to deliver equal or greater bomb loads while also having superior performance, range and defensive capabilities. Modern aircraft carrying out similar missions include light attack aircraft , strike fighters , and counter-insurgency aircraft . The first aircraft purposely designed for bombing missions were
18758-600: The entire trailing edge of the wing to achieve the short takeoff and landing requirement, something that later designs would achieve with the technically more complex swing-wing approach. No ailerons were fitted, control in roll instead being implemented by differential movement of the slab tailplanes. The wing loading was high for its time, enabling the aircraft to fly at very high speed and low level with great stability without being constantly upset by thermals and other ground-related weather phenomena. The EE Chief Test Pilot , Wing Commander Roland Beamont , favourably compared
18924-482: The era of manned combat was at an end and ballistic missiles were the weapons of the future. This viewpoint was vigorously debated by the aviation industry and within the Ministry of Defence for years. Senior RAF officers argued against the White Paper's premise, stating the importance of mobility, and that the TSR-2 could not only replace the Canberra, but potentially the entire V bomber force. In addition to
19090-408: The fall of the communist governments of Europe from 1989, which concluded with the fall of the Soviet Union in 1991. The Western Bloc included the US and a number of First World nations that were generally capitalist and liberal democratic but tied to a network of often authoritarian Third World states, most of which were the European powers' former colonies . The Eastern Bloc was led by
19256-400: The final few flights, when XR219 was fitted with additional tie-struts on the already complex landing gear, was there a significant reduction in them. The last test flight took place on 31 March 1965. Although the test flying programme was not completed and the TSR-2 was undergoing typical design and systems modifications reflective of its sophisticated configuration, "[T]here was no doubt that
19422-401: The formation of NATO , which was essentially a defensive agreement in 1949. The Soviet Union countered with the Warsaw Pact in 1955, which had similar results with the Eastern Bloc. As by that time the Soviet Union already had an armed presence and political domination all over its eastern satellite states, the pact has been long considered superfluous. Although nominally a defensive alliance,
19588-485: The front half, EE the rear. The TSR-2 was to be powered by two Bristol-Siddeley Olympus reheated turbojets , advanced variants of those used in the Avro Vulcan . The Olympus would be further developed and would power the supersonic Concorde . The design featured a small shoulder-mounted delta wing with down-turned tips, an all-moving swept tailplane and a large all-moving fin . Blown flaps were fitted across
19754-443: The fuselage. If no internal weapons were carried, a further 570 imp gal (680 US gal; 2,600 L) could be carried in a tank in the weapons bay. Later variants would have been fitted with variable-geometry wings. The TSR-2 was also to be equipped with a reconnaissance pack in the weapons bay which included an optical linescan unit built by EMI , three cameras and a sideways-looking radar (SLR) in order to carry out
19920-411: The government intended to foster cooperation between certain companies and encourage mergers. Another political matter, that did not help, was the mutual distrust between the various services. At the time that GOR.339 was being defined, the Royal Navy was proceeding with Buccaneer. The savings involved in both forces using a common aircraft would be considerable, and Blackburn offered the RAF a version of
20086-529: The kind of world-view, the kind of beliefs, and the social structure that would probably prevail in a state which was at once unconquerable and in a permanent state of "cold war" with its neighbours. In The Observer of 10 March 1946, Orwell wrote, "...after the Moscow conference last December, Russia began to make a 'cold war' on Britain and the British Empire." The first use of the term to describe
20252-504: The lower yield by including, in the specifications for both the bomb and TSR-2, provision for releasing the smaller weapons in salvos, dropping sticks of four of the revised OR.1177, later named WE.177A , at 3,000 ft (914m) intervals to prevent the detonation of the first weapon destroying the succeeding ones before they could, in turn, detonate. This led to the requirement that the TSR-2 must be able to carry four WE.177As, two internally and two on external underwing stores pylons —the width of
20418-402: The loyalty of non-aligned countries , such as India . By the 1970s, Japan and Western Europe rebuilt their economies, allowing them more diplomatic independence. After the Sino-Soviet split between the USSR and China in 1961, the U.S. initiated contacts with China in 1972 . In the same year, the US and USSR signed a series of treaties limiting their nuclear arsenals, which eased tensions for
20584-536: The majority of its reconnaissance tasks. Unlike modern linescan units that use infrared imaging , the TSR-2's linescan would use daylight imaging or an artificial light source to illuminate the ground for night reconnaissance. Carriage of the existing Red Beard tactical nuclear bomb had been specified at the beginning of the TSR-2 project, but it was quickly realised that Red Beard was unsuited to external carriage at supersonic speeds, had safety and handling limitations, and its 15 kt yield would be inadequate for
20750-521: The mission was to be flown at Mach 0.92. If the entire mission were to be flown at the low 200 ft altitude, the mission radius was reduced to 700 nmi (810 mi; 1,300 km). Heavier weapons loads could be carried with further reductions in range. Plans for increasing the TSR-2's range included fitting external tanks: one 450-imperial-gallon (540 US gal; 2,000 L) tank under each wing or one 1,000 imp gal (1,200 US gal; 4,500 L) tank carried centrally below
20916-414: The most prominent architects of America's early Cold War strategy, especially those who believed that the Cold War would eventually be fought by political rather than military means, such as George F. Kennan. Soviet and Eastern Bloc authorities used various methods to suppress Western broadcasts, including radio jamming . American policymakers, including Kennan and John Foster Dulles , acknowledged that
21082-564: The others were well short, notably P.1121. But more important was that the supersonic performance of all of these designs was very limited, and especially the range that the aircraft could fly whilst supersonic. A further and more rigorous GOR.339 was released, and at a September 1957 meeting the Ministry called for a new round of submissions on 31 January 1958, and made the first formal statement that only those submissions from paired up companies would be considered. Eight companies were invited to enter, leading to thirteen submissions: By February,
21248-671: The policy change. Once again, the East Berlin communists attempted to disrupt the Berlin municipal elections , which were held on 5 December 1948 and produced a turnout of 86% and an overwhelming victory for the non-communist parties. The results effectively divided the city into East and West, the latter comprising US, British and French sectors. 300,000 Berliners demonstrated and urged the international airlift to continue, and US Air Force pilot Gail Halvorsen created " Operation Vittles ", which supplied candy to German children. The Airlift
21414-441: The political decision-making level on either side. Similarly, there is no evidence, on either side, of any major political or military decision that was prematurely discovered through espionage and thwarted by the other side. There also is no evidence of any major political or military decision that was crucially influenced (much less generated) by an agent of the other side. According to historian Robert L. Benson, "Washington's forte
21580-479: The presence of the Red Army —alarmed the US and UK. Western leaders saw this as a clear instance of Soviet expansionism, clashing with their vision of a democratic Europe. Economically, the divide was sharpened with the introduction of the Marshall Plan in 1947, a US initiative to provide financial aid to rebuild Europe and prevent the spread of communism by stabilizing capitalist economies. The Soviet Union rejected
21746-471: The range where even jet powered fighters were able to intercept it. The Canberra could simply fly over its enemy with relative impunity, a quality that made it naturally suited to aerial reconnaissance missions. The design was so successful that it was licensed for production in the United States, one of very few such cases. The Martin RB-57D and RB-57F American-built reconnaissance subtypes further extended
21912-462: The reasons for the spiralling costs of the project. Some features, such as forward looking radar (FLR) and side-looking radar for navigational fixing, only became commonplace on military aircraft years later. These features allowed for an innovative autopilot system which, in turn, enabled long distance terrain-following sorties as crew workload and pilot input had been greatly reduced. "The practical solution of appointing one prime contractor to manage
22078-469: The source of the term, Lippmann traced it to a French term from the 1930s, la guerre froide . The roots of the Cold War can be traced back to diplomatic and military tensions preceding World War II. The 1917 Russian Revolution and the subsequent Treaty of Brest-Litovsk , where Soviet Russia ceded vast territories to Germany, deepened distrust among the Western Allies. Allied intervention in
22244-463: The specific post-war geopolitical confrontation between the Soviet Union and the United States came in a speech by Bernard Baruch , an influential advisor to Democratic presidents, on 16 April 1947. The speech, written by journalist Herbert Bayard Swope , proclaimed, "Let us not be deceived: we are today in the midst of a cold war." Newspaper columnist Walter Lippmann gave the term wide currency with his book The Cold War . When asked in 1947 about
22410-698: The targets assigned. Instead, in 1959, a successor to Red Beard, an "Improved Kiloton Bomb" to a specification known as Operational Requirement 1177 (OR.1177), was specified for the TSR-2. In the tactical strike role, the TSR-2 was expected to attack targets beyond the forward edge of the battlefield assigned to the RAF by NATO , during day or night and in all weathers. These targets comprised missile sites, both hardened and soft, aircraft on airfields, runways, airfield buildings, airfield fuel installations and bomb stores, tank concentrations, ammunition and supply dumps, railways and railway tunnels, and bridges. OR.1177 specified 50, 100, 200 and 300 kt yields, assuming
22576-401: The undercarriage down and engine power strictly controlled—with limits of 250 kn (290 mph; 460 km/h) and 10,000 ft (3,000 m) on the first (15-minute) flight. Shortly after takeoff on XR219's second flight, vibration from a fuel pump at the resonant frequency of the human eyeball caused the pilot to throttle back one engine to avoid momentary loss of vision. Only on
22742-493: The whole programme with sub-contractors operating under strictly controlled and disciplined conditions was, if considered at all, waived aside." Wing Commander R.P. Beamont, the first TSR-2 pilot. There were considerable problems with realising the design. Some contributing manufacturers were employed directly by the Ministry rather than through BAC, leading to communication difficulties and further cost overruns. Equipment, an area in which BAC had autonomy, would be supplied by
22908-401: The wings up to a 37.5 m (123 ft) span for extremely high altitude capabilities. It was realized that the Canberra's advantages would be eroded by improvements in enemy interceptor aircraft . As early as 22 February 1952, Air Vice Marshal Geoffrey Tuttle wrote that "Frankly, I do not believe that we will get much operational value out of the Canberra from 1955 onwards... the aircraft
23074-411: The world, while Soviet involvement in regime change included the funding of left-wing parties , wars of independence , revolutions and dictatorships. As nearly all the colonial states underwent decolonization and achieved independence in the period from 1945 to 1960, many became Third World battlefields in the Cold War. At the end of World War II, English writer George Orwell used cold war , as
23240-486: The world. Movements against nuclear weapons testing and for nuclear disarmament took place, with large anti-war protests . By the 1970s, both sides had started making allowances for peace and security, ushering in a period of détente that saw the Strategic Arms Limitation Talks and the 1972 visit by Richard Nixon to China that opened relations with China as a strategic counterweight to
23406-505: Was 'signals' intelligence - the procurement and analysis of coded foreign messages." leading to the Venona project or Venona intercepts, which monitored the communications of Soviet intelligence agents. Moynihan wrote that the Venona project contained "overwhelming proof of the activities of Soviet spy networks in America, complete with names, dates, places, and deeds." The Venona project
23572-428: Was a limitation due to aerodynamic heating of the bomb's casing. WE.177A was limited to a maximum carriage time of five minutes at Mach 1.15 at low level on TSR-2, otherwise the bomb's temperature would rise above its permitted maximum. This would impose a severe operational restriction on TSR-2, as the aircraft was designed for Mach 1+ cruise at this height. Nuclear stand-off missiles were also proposed for
23738-412: Was a strong promise that West Germany would not develop nuclear weapons. Widespread fears of another rise of German militarism necessitated the new military to operate within an alliance framework under NATO command. In 1955, Washington secured full German membership of NATO. In May 1953, Lavrentiy Beria , by then in a government post, had made an unsuccessful proposal to allow the reunification of
23904-508: Was agreed upon, notably reductions in combat radius to 650 nmi (750 mi; 1,200 km), the top speed to Mach 1.75 and takeoff run up increased from 1,800 to 3,000 feet (550 to 915 m). By the 1960s, the United States military was developing the swing-wing F-111 project as a follow-on to the Republic F-105 Thunderchief , a fast low-level fighter-bomber designed in the 1950s with an internal bay for
24070-497: Was also asked to consider the F-111 as an alternative cost-saving measure. In response to suggestions of cancellation, BAC employees held a protest march, and the new Labour government, which had come to power in 1964, issued strong denials. However, at two Cabinet meetings held on 1 April 1965, it was decided to cancel the TSR-2 on the grounds of projected cost, and instead to obtain an option agreement to acquire up to 110 F-111 aircraft with no immediate commitment to buy. This decision
24236-567: Was also fearful of a reconstituted Germany; his vision of a post-war Germany did not include the ability to rearm or pose any kind of threat to the Soviet Union. In early 1948, following reports of strengthening "reactionary elements", Czech Communists executed a coup d'état in Czechoslovakia (resulting in the formation of the Czechoslovak Socialist Republic (9 May 1948)), the only Eastern Bloc state that
24402-474: Was announced in the budget speech of 6 April 1965. The maiden flight of the second development batch aircraft, XR220 , was due on the day of the announcement, but following an accident in conveying the airframe to Boscombe Down, coupled with the announcement of the project cancellation, it never happened. Ultimately, only the first prototype, XR219 , ever took to the air. A week later, the Chancellor defended
24568-433: Was as much a logistical as a political and psychological success for the West; it firmly linked West Berlin to the United States. In May 1949, Stalin backed down and lifted the blockade. In 1952, Stalin repeatedly proposed a plan to unify East and West Germany under a single government chosen in elections supervised by the United Nations, if the new Germany were to stay out of Western military alliances, but this proposal
24734-558: Was common for these aircraft to also be used for level bombing missions. The Bristol Beaufort , Nakajima B5N and Grumman TBF Avenger , while designed as torpedo bombers, saw some action purely in the light bomber role. Types designed before the war as heavy fighters were also frequently adapted as light bombers, including the Messerschmitt Bf 110 , Potez 633 , Fokker G.I , Kawasaki Ki-45 , Bristol Beaufighter , and Lockheed P-38 Lightning . Light attack aircraft such as
24900-679: Was contingent upon German economic recovery. One month later, Truman signed the National Security Act of 1947 , creating a unified Department of Defense , the Central Intelligence Agency (CIA), and the National Security Council (NSC). These would become the main bureaucracies for US defense policy in the Cold War. Stalin believed economic integration with the West would allow Eastern Bloc countries to escape Soviet control, and that
25066-451: Was essentially the wings and tail sections of the P.17, combined with the longer fuselage of the Type 571, with the design being built in two parts, Vickers the front and EE the rear, and the bolted together at a point just in front of the wing. The existence of GOR.339 was revealed to the public in December 1958 in a statement to the House of Commons . Under pressure by the recommendations of
25232-471: Was issued to various aircraft manufacturers in March 1957. This requirement was exceptionally ambitious for the technology of the day, requiring a supersonic all-weather aircraft that could deliver nuclear weapons over a long range, operate at high level at Mach 2+ or low level at Mach 1.2, with STOL or possible VTOL performance. The latter requirement was a side-effect of common battle plans from
25398-472: Was kept highly secret even from policymakers until the Moynihan Commission in 1995. Despite this, the decryption project had already been betrayed and dispatched to the USSR by Kim Philby and Bill Weisband in 1946, as was discovered by the US by 1950. Nonetheless, the Soviets had to keep their discovery of the program secret, too, and continued leaking their own information, some of which
25564-470: Was later revealed that the decision to drop the Hawker effort had been taken as early as August, and that their later submissions were effectively a "going through the motions" effort. Official opinions of EE's management found it lacking in comparison to Vickers, but the combination of the two was felt by officialdom to be a useful marriage and accordingly the development contract was awarded to Vickers, with English Electric as sub-contractor. The ultimate design
25730-506: Was left as the world's sole superpower. In February 1946, George F. Kennan 's " Long Telegram " from Moscow to Washington helped to articulate the US government's increasingly hard line against the Soviets, which would become the basis for US strategy toward the Soviet Union for the duration of the Cold War. The telegram galvanized a policy debate that would eventually shape the Truman administration 's Soviet policy. Washington's opposition to
25896-477: Was no way it would ever win the contract. A 27 January 1958 meeting between Roy Dodson , Frank Spriggs and J.R. Ewins eventually decided to promote the P.1129 as their primary submission, using the P.1129 as the basis and adding in some features from the 739. Notably, the wing was made thinner and area rule was applied to optimize the design for flight at Mach 1.34. In May, the Air Ministry issued OR.343,
26062-457: Was not until the widespread introduction of the first of the Soviet Union 's surface-to-air missiles (SAMs) in the late 1950s that the first major threat appeared. SAMs had speed and altitude performance much greater than any contemporary aircraft. The Canberra, and other high-altitude aircraft like the British V bombers or United States' Boeing B-52 Stratofortress , were extremely vulnerable to these weapons. The first aircraft to fall victim to
26228-545: Was now restricted to the island of Taiwan , the nationalist government of which exists to this day. The Kremlin promptly created an alliance with the newly formed People's Republic of China. According to Norwegian historian Odd Arne Westad , the communists won the Civil War because they made fewer military mistakes than Chiang Kai-Shek made, and because in his search for a powerful centralized government, Chiang antagonized too many interest groups in China. Moreover, his party
26394-403: Was parity in the quantity and quality of secret information obtained by each side. However, the Soviets probably had an advantage in terms of HUMINT (human intelligence or interpersonal espionage) and "sometimes in its reach into high policy circles." In terms of decisive impact, however, he concludes: We also can now have high confidence in the judgment that there were no successful "moles" at
26560-651: Was purchased for use both by the Royal Naval Air Service (RNAS) and the Royal Flying Corps (RFC). The Eastbourne RNAS Squadron , operating the T.B.3, carried out the first bombing attack of World War I: on 25 November 1914, under the command of Charles Rumney Samson , the squadron attacked coastal gun batteries operated by German Empire forces, at Middelkerke , Belgium . Most bombers used on World War I battlefields were in fact light bombers: typically single- engine biplanes with
26726-494: Was still useful to the American program. According to Moynihan, even President Truman may not have been fully informed of Venona, which may have left him unaware of the extent of Soviet espionage. Clandestine atomic spies from the Soviet Union, who infiltrated the Manhattan Project at various points during WWII, played a major role in increasing tensions that led to the Cold War. In addition to usual espionage,
26892-652: Was the victim of ever-rising costs and inter-service squabbling over Britain's future defence needs, which together led to the controversial decision in 1965 to scrap the programme. It was decided to order an adapted version of the General Dynamics F-111 instead, but that decision was later rescinded as costs and development times increased. The replacements included the Blackburn Buccaneer and McDonnell Douglas F-4 Phantom II , both of which had previously been considered and rejected early in
27058-514: Was to be 1,000 nmi (1,200 mi; 1,900 km) operating off runways of no more than 3,000 ft (910 m). The TSR-2 was to be able to operate at 200 ft (60 m) above the ground at speeds of Mach 1.1; its range would allow it to operate strategically in addition to tactical scenarios. "There are jobs that missiles cannot do, they cannot reconnoitre enemy positions, they cannot be moved rapidly from one theatre to another, nor can they be switched from one target to another, only
27224-402: Was to provide high-altitude, high-speed stand-off, side-looking radar and photographic imagery and signals intelligence , aerial reconnaissance . Only one airframe flew and test flights and weight-rise during design indicated that the aircraft would be unable to meet its original stringent design specifications. The design specifications were reduced as the result of flight testing. The TSR-2
27390-655: Was turned down by the Western powers. Some sources dispute the sincerity of the proposal. Britain, France, the United States, Canada and eight other western European countries signed the North Atlantic Treaty of April 1949, establishing the North Atlantic Treaty Organization (NATO). That August, the first Soviet atomic device was detonated in Semipalatinsk , Kazakh SSR . Following Soviet refusals to participate in
27556-487: Was weakened during the war against Japan . Meanwhile, the communists told different groups, such as the peasants, exactly what they wanted to hear, and they cloaked themselves under the cover of Chinese nationalism . Confronted with the communist revolution in China and the end of the American atomic monopoly in 1949, the Truman administration quickly moved to escalate and expand its containment doctrine. In NSC 68 ,
