Описание: From Wikipedia, the free encyclopedia The SEPECAT "Jaguar" is a British-French jet attack aircraft originally used by the British Royal Air Force and the French Air Force in the close air support and nuclear strike role. It is still in service in significantly upgraded form with the Indian Air Force. Originally conceived in the 1960s as a jet trainer with a light ground attack capability, the requirement for the aircraft soon changed to include supersonic performance, reconnaissance and tactical nuclear strike roles. A carrier-based variant was also planned for French service, but this was cancelled in favour of the cheaper Dassault "Super 'Etendard". The airframes were manufactured by SEPECAT (Soci'et'e Europ'eenne de Production de l'avion Ecole de Combat et d'Appui Tactique), a joint venture between Breguet and the British Aircraft Corporation, one of the first major joint-Anglo-French military aircraft programmes. The Jaguar was exported to India, Oman, Ecuador and Nigeria. With various air forces, the "Jaguar" was used in numerous conflicts and military operations in Mauritania, Chad, Iraq, Bosnia, and Pakistan, as well as providing a ready nuclear delivery platform for Britain, France, and India throughout the latter half of the Cold War and beyond. In the Gulf War, the "Jaguar" was praised for its reliability and was a valuable coalition resource. The aircraft served with the French Air Force as the main strike/attack aircraft until 1 July 2005, and with the Royal Air Force until the end of April 2007. It was replaced by the Panavia "Tornado" and the Eurofighter "Typhoon" in the RAF and the Dassault "Rafale" in the French Air Force. Development Background The Jaguar programme began in the early 1960s, in response to a British requirement (Air Staff Target 362) for an advanced supersonic jet trainer to replace the Folland "Gnat" T1 and Hawker "Hunter" T7, and a French requirement (ECAT or 'Ecole de Combat et d'Appui Tactique, "Tactical Combat Support Trainer") for a cheap, subsonic dual role trainer and light attack aircraft to replace the Fouga "Magister", Lockheed T-33 "Shooting Star" (or T-Bird) and Dassault "Myst`ere IV". In both countries several companies tendered designs: BAC, Hunting, Hawker Siddeley and Folland in Britain; Breguet, Potez, Sud-Aviation, Nord, and Dassault from France. A Memorandum of Understanding was signed in May 1965 for the two countries to develop two aircraft, a trainer based on the ECAT, and the larger AFVG (Anglo-French Variable Geometry). Cross-channel negotiations led to the formation of SEPECAT (Soci'et'e Europ'eenne de Production de l'Avion d''Ecole de Combat et d'Appui Tactique – the "European company for the production of a combat trainer and tactical support aircraft") in 1966 as a joint venture between Breguet and the British Aircraft Corporation to produce the airframe. Though based in part on the Breguet Br.121, using the same basic configuration and an innovative French-designed landing gear, the "Jaguar" was built incorporating major elements of design from BAC – notably the wing and high lift devices. Production of components would be split between Breguet and BAC, and the aircraft themselves would be assembled on two production lines; one in the UK and one in France, To avoid any duplication of work, each aircraft component had only one source. The British light strike/tactical support versions were the most demanding design, requiring supersonic performance, superior avionics, a cutting edge nav/attack system of more accuracy and complexity than the French version, moving map display, laser range-finder and marked-target seeker (LRMTS). As a result, the initial Br.121 design needed a thinner wing, redesigned fuselage, a higher rear cockpit, and after-burning engines. While putting on smiling faces for the public, maintaining the illusion of a shared design, the British design departed from the French sub-sonic Breguet 121 to such a degree that it was effectively a new design. A separate partnership was formed between Rolls-Royce and Turbomeca to develop the Adour afterburning turbofan engine. The Br.121 was proposed with Turbomeca's Tourmalet engine for ECAT but Breguet preferred the RR RB.172 and their joint venture would use elements of both. The new engine, which would be used for the AFVG as well, would be built in Derby and Tarnos. Previous collaborative efforts between Britain and France had been complicated – the AFVG programme ended in cancellation, and controversy surrounded the development of the supersonic airliner Concorde. Whilst the technical collaboration between BAC and Breguet went well, when Dassault took over Breguet in 1971 it encouraged acceptance of its own designs, such as the "Super 'Etendard" naval attack aircraft and the "Mirage F1", for which it would receive more profit, over the Anglo-French "Jaguar". The initial plan was for Britain to buy 150 "Jaguar" B trainers, with its strike requirements being met by the advanced BAC-Dassault AFVG aircraft, with France to buy 75 "E" trainers ('ecole) and 75 "A" single-seat strike attack aircraft (appui). Dassault favoured its own "Mirage" G aircraft above the collaborative AFVG, and in June 1967, France cancelled the AFVG on cost grounds. This left a gap in the RAF's planned strike capabilities for the 1970s; at the same time as France's cancellation of the AFVG, Germany was expressing a serious interest in the "Jaguar", and thus the design became more oriented towards the low-level strike role. The RAF had initially planned on a buy of 150 trainers; however, with both the BAC TSR-2 tactical strike aircraft and Hawker Siddeley P.1154 supersonic V/STOL fighter cancelled, the RAF were looking increasingly hard at their future light strike needs and realizing that they now needed more than just advanced trainers with some secondary counter insurgency capability. The RAF's strike line-up was at this point intended to consist of American General Dynamics F-111s plus the AFVG for lighter strike purposes. There was concern that both F-111 and AFVG were high risk projects and with the French already planning on a strike role for the "Jaguar", there was an opportunity to introduce a serious backup plan for the RAF's future strike needs – the "Jaguar". As a result, by October 1970, the RAF's requirements had changed to 165 single-seat strike aircraft and 35 trainers. The "Jaguar" was to replace the McDonnell Douglas "Phantom" FGR2 in the close air support, tactical reconnaissance and tactical strike roles, freeing the "Phantom" to be used for air defence. Both the French and British trainer requirements had developed significantly, and were eventually fulfilled instead by the "Alpha Jet" and Hawker Siddeley "Hawk" respectively. The French, meanwhile, had chosen the "Jaguar" to replace the Aeronavale's Dassault "'Etendard IV", and increased their order to include an initial 40 of a carrier-capable maritime version of the Jaguar, the "Jaguar M", for the Aeronavale. From these apparently disparate aims would come a single and entirely different aircraft: relatively high-tech, supersonic, and optimised for ground-attack in a high-threat environment. Prototypes The first of eight prototypes flew on 8 September 1968, a two-seat design fitted with the first production model Adour engine. This aircraft later went supersonic on its third flight but was lost on landing on 26 March 1970 following an engine fire. The second prototype flew in February 1969; a total of three prototypes appeared in flight at the Paris Air Show that year. The first French "A" prototype flew in March 1969. In October a British "S" conducted its first flight. An "M" prototype flew in November 1969. The "M" had a strengthened airframe, an arrestor hook and different undercarriage: twin nosewheel and single mainwheels. After testing in France it went to RAE at Thurleigh for carrier landing trials from their land based catapult. In July 1970 it made real take offs and landings from the French carrier Clemenceau. From these trials there were doubts about the throttle response in case of an aborted landing; the shipboard testing also revealed problems with the aircraft's handling when flying on one engine, although planned engine improvements were to have rectified these problems. The "M" was considered a suitable replacement for the "Etendard IV" but the Aeronavale would only be able to purchase 60 instead of 100 aircraft. Furthermore, the "Jaguar M" was expensive, limiting the size of the force the French Navy could afford. In 1971, Dassault proposed the "Super 'Etendard", claiming that it was a simpler and cheap development of the existing "'Etendard IV", and in 1973, the French Navy agreed to order it instead of the "Jaguar", although rising costs of the "Super 'Etendard" meant that only 71 of the planned 100 aircraft were purchased. The M was cancelled by the French government in 1973. Design Overview The "Jaguar" is an orthodox single-seat, swept-wing, twin-engine monoplane design, with tall tricycle-type retractable landing gear. In its original configuration, it had a maximum take-off weight in the 15 tonne class; and could manage a combat radius on internal fuel alone of 850 km (530 mi), giving the Jaguar a greater operational range than competitor aircraft such as the Mikoyan MiG-27. The aircraft had hardpoints fitted for an external weapons load of up to 10,000 lb (4,500 kg), typical weapons fitted included the MATRA LR.F2 rocket pod, BAP 100-mm bombs, MATRA AS37 anti-radar missiles, AIM-9 Sidewinder missiles, and Rockeye cluster bombs. The RAF's "Jaguar's" gained several new weapons during the Gulf War, including CRV7 high-velocity rockets and American CBU-87 cluster bombs. Finally, the Jaguar was equipped with either a pair of French DEFA cannons, or alternatively British ADEN cannons. The Jaguar International had the unusual optional provision for overwing pylons, used for short-range air-to-air missiles, such as the Matra R550 "Magic" or the AIM-9 "Sidewinder". This option frees up the under-wing pylons for other weapons and stores. RAF Jaguars gained overwing pylons in the buildup to Operation Granby in 1990, but French Jaguars were not modified. The RAF's "Jaguar" 97's were intended to be wired for the carriage of ASRAAMs on the overwing launchers, but clearance of this weapon was never completed because of funding cuts.
