The SEPECAT Jaguar is an Anglo-French ground attack aircraft that was still in service with several export customers by the end of the 20st century, notably the Indian Air Force and the Royal Air Force of Oman. It was among the first major Anglo-French military aircraft programs. The aircraft served as one of the French Air Force's main attack aircraft until July 1, 2005 (when it was replaced by Dassault Rafale) and with the Royal Air Force until the end of April 2007.
The Jaguar program began in the early 1960s, in response to a British requirement for an advanced supersonic jet trainer, and a French need for a cheap, subsonic dual role trainer and attack aircraft with good short field performance. 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. It was planned as a replacement for the RAF Hawker Hunter and the Armée de l'Air F-100 Super Sabre.
Cross-channel negotiations led to the formation of SEPECAT (Société Européenne de Production de l'Avion d'école 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 Bréguet - now Dassault Aviation - and the British Aircraft Corporation to produce the airframe, and a separate teaming of Rolls-Royce and Turboméca to develop the Adour afterburning turbofan engine. Though based in part on the Bréguet 121, using the same basic configuration and an innovative French designed landing gear, the Jaguar as built also incorporated major elements designed by BAC - notably the wing and high lift devices.
The first of 8 prototypes flew on September 8, 1968. It was an orthodox single-seat, swept-wing, twin-engine design but with tall landing gear. 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. Maximum speed was Mach 1.6 (and Mach 1.1 at sea level) and hardpoints were fitted for an external weapons load of up to 10,000 lb (or 4,500 kg).
The aircraft has been updated several times and remains in front-line service with India and Oman. It is to be replaced by the Eurofighter Typhoon in the RAF and the Rafale in the Armée de l'Air. India plans to replace its Jaguar fleet with the Medium Combat Aircraft.
Demands by the UK Treasury to cut the defence budget led to reports that the Jaguar was a possible candidate for early retirement. Announcing plans for the future of the British military on July 21, 2004, Defence Secretary Geoff Hoon detailed plans to withdraw the Jaguar by 2007.
Critics say the aircraft was near the end of its service life and did not have all the capabilities required of a front line jet. Proponents argued that the aircraft was recently updated and was the most cost effective of all the RAF's fast jet force.
India on the other hand is modernizing its current Jaguar fleet and also placed an order for 29 additional upgraded Jaguar IM aircraft from Hindustan Aeronautics in 2005. The India Air Force, which operates two different types of Rolls Royce - Turbomeca engines, Mk.804E and Mk.811 (produced under license by HAL) will possibly be upgrading their Mk.811 engines to the Mk.821 which will combine a number of thrust and reliability improvements gained from the RAF Jaguar experience in the last 5 years. This will allow the Indian Air Force to have a more capable aircraft at medium and high level sortie profiles where most of the flying is carried out. The engines may also share similar components to the Adour Mk.871 which has been fitted to the Indian Air Force Hawk supplied by BAES.
The Jaguar International (in common with the Lightning) has provision for overwing pylons. Mounted on the Jaguar they are 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 build up to Operation GRANBY in 1990, but French Jaguars were not modified. The RAF's Jaguar 97s were wired for the carriage of ASRAAM on the overwing launchers, but clearance of this weapon was never completed due to funding cuts.
The Armée de l'Air took delivery of the first production Jaguar in 1973, one of an eventual 160 single-seat Jaguar As. For type conversion training, France also took 40 of the two-seat Jaguar E. After Bréguet was purchased by Dassault, the proposed Jaguar M variant, a carrier version for the French Aeronavale, was cancelled in favor of the Dassault Super étendard.
The RAF accepted delivery of the first of 165 single-seat Jaguar GR.1s (or Jaguar S) with 54(F) squadron in 1974. These were supplemented by 35 two-seat trainers, the Jaguar T2 (or Jaguar B according to the manufacturer's designation). The Jaguar S and B had a more comprehensive nav/attack system than the A and E models used by the Armée de l'Air, and used 30 mm Aden cannon instead of 30 mm DEFA 553s. Some RAF Jaguars were used for rapid deployment and regional reinforcement, operating with the Coltishall wing, and others flew in the nuclear strike role from RAF Bruggen. The latter aircraft were the RAF's only single-seat strike platforms, and were soon replaced by Tornados.
In December 1983, 75 RAF Jaguars were updated to the GR.1A and T.2A standard with FIN1064 navigation and attack systems replacing the original NAVWASS. At about the same time, most were also re-engined with Adour 104 engines. In 1994, ten GR.1As and two T.2As were upgraded with the capability to carry the TIALD laser designator pod and redesignated GR.1B or T.2B respectively.
The upgraded GR.3A (also known as Jaguar 97) introduced fleet-wide TIALD LDP compatibility, provision for the EO GP1 (JRP) digital reconnaissance pod, a helmet mounted sight, a glass cockpit with a large AMLCD display and a new HUD, a new hand controller and stick top, GPS, TERPROM Terrain Referenced Navigation, an Improved Data Modem datalink, and improved Night vision goggles compatibility. The interim GR.3 (Jaguar 96) was delivered in three standards, for recce, attack and TIALD, but all were converted to Jaguar 97 - GR.3A standards. All GR.3As were subsequently re-engined with the new Adour 106 turbofan. A number of T.2 trainers were also upgraded to Jaguar 96 standard and redesignated T.4.
Jaguars were also sold to a number of overseas countries. The largest single customer was the Republic of India which purchased about 40 of these aircraft and also acquired the license to manufacture 100 of them indigenously. Hindustan Aeronautics Limited, India's leading aerospace agency, manufactured 100 Jaguars under the name Shamsher. The Jaguar International was an export version which was sold to Ecuador, Nigeria and Oman. Oman's Jaguars have been brought to full GR3A standards and serve with No.s 8 and 20 Squadrons.
The Jaguar saw combat during the first Gulf War of 1991, with the Armée de l'Air and RAF, the Balkan wars with the RAF, the Kosovo War with the Armée de l'Air and the Kargil War with the Indian Air Force. However, during the 1991 Gulf War, the RAF Jaguars were "paired" with Buccaneers, which had already been upgraded with TIALD.
One Jaguar was converted into the Jaguar Active Control Technology (ACT) with fly-by-wire controls and aerodynamic alterations to the airframe. The aerodynamic instability improved maneuverability and test data was used for the Eurofighter development.
The RAF aircraft flew their last operational sorties on April 30, 2007 when it ceased to be a deployable force element and when No.6 Squadron "down-declared", though flying continued. At least two aircraft continued to fly with QinetiQ at Boscombe Down after No.6 Squadron's withdrawal. On 20 December 2007, a Jaguar undertook the last ever British military Jaguar flight.
A total of 543 aircraft were built :
