SEPECAT Jaguar

The SEPECAT Jaguar is an Anglo-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 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 Navy service, but this was cancelled in favour of the cheaper, fully French-built Dassault-Breguet Super Étendard. The aircraft were manufactured by SEPECAT (Société Européenne 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. The aircraft 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 the United Kingdom, 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 ''École 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 and Dassault Mystère IV."Military Dassault aircraft: Jaguar."
''Dassault Aviation.'' Retrieved: 15 November 2010. 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).Jackson 1992, p. 56.

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"Wagner 2009, p. 122.) 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.Jackson 1992, pp. 58, 71.

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.Taylor 1980, p. 708. 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.Wallace 1984, p. 27. 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 Étendard naval attack aircraft and the Mirage F1, for which it would receive more profit, over the Anglo-French Jaguar.Jackson 1992, p. 77.

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 (''école'') 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.Segell 1998, p. 169. 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,Segell 1998, p. 172. and thus the design became more oriented towards the low-level strike role.Jackson 1992, pp. 56, 58.

With the cancellation of both the BAC TSR-2 tactical strike aircraft and Hawker Siddeley P.1154 supersonic V/STOL fighter, 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. At this point, the RAF's proposed strike fleet was to be the 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 credible 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.Jackson 1992, p. 58.

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.Hobbs 2008, p.37. Both the French and British trainer requirements had developed significantly, and were eventually fulfilled instead by the Alpha Jet and Hawker Siddeley Hawk respectively.Wallace 1984, p. 28. The French, meanwhile, had chosen the Jaguar to replace the Aeronavale's Dassault Étendard IV, and increased their order to include an initial 40 of a carrier-capable maritime version of the Jaguar, the Jaguar M.Bowman 2007, p. 21. 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.''Flight'' 12 September 1968, p. 391.Taylor 1971, p. 107. This aircraft 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 flew 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.''Flight'' 16 October 1969, p. 600.

A Jaguar M prototype flew in November 1969. This 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, after which, in July 1970, it underwent a series of shipboard trials 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 afford 60 instead of 100 aircraft.

In 1971, Dassault proposed the Super Étendard, claiming that it was a simpler and cheaper development of the existing Étendard IV, and in 1973, the French Navy ordered it instead of the Jaguar. However, rising costs meant that only 71 of the planned 100 Super Étendards 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;Taylor 1980, pp. 106–107. with a combat radius on internal fuel of , 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.Glenn 2005, p. 9.Glenn 2005, p. 40. The RAF's Jaguars gained several new weapons during the Gulf War, including CRV7 high-velocity rockets and American CBU-87 cluster bombs.Jackson 1992, pp. 63–66. Finally, the Jaguar was equipped with either a pair of French DEFA cannons,Owen 2000, p. 217. or British ADEN cannons.Wagner 2009, p. 123.

The Jaguar International had the unusual option of overwing pylons, used for short-range air-to-air missiles, such as the Matra R550 Magic or the Sidewinder. This option freed up the under-wing pylons for other weapons and stores. RAF Jaguars gained overwing pylons in the buildup to Operation Granby in 1990,Jackson 1992, p. 64. but French Jaguars were not modified.Jackson 1992, p. 69.

Engine

The SEPECAT Jaguar is powered by the Rolls-Royce Turbomeca Adour turbofan engine, which was developed in parallel with, and primarily for the Jaguar. A separate partnership was formed between Rolls-Royce and Turbomeca to develop the Adour, a two-shaft turbofan engine with afterburner. Twin engines were selected for survivability. Ease of maintenance was major consideration, an engine change being possible within 30 minutes. For the Jaguars it needed a low bypass capable of high thrust for take off, supersonic flight and low level "dashes".

When the first prototype Jaguar flew on 8 September 1968, it was also the first flight for the engine. In its initial development the Adour engine had complications with the stability of the afterburner system, and shipboard testing showed slow throttle response times, problematic in the situation of an aborted landing; engine improvements rectified these problems prior to the Jaguar coming into service. In French service, the Jaguars were introduced using the original Mk.101 engine. RAF Jaguars entered service using the Mk.102 engine, mainly featuring better afterburner-throttle control over the Mk.101. The RAF later had its Jaguars re-engined around 1981 with the improved Adour Mk.104, and again in 1999 with the Mk.106, each providing greater performance.Jackson 1992, p. 94.

The Adour was developed into both afterburning and non-afterburning models; the Hawk, which had beaten the Jaguar to fulfill the Air Staff Target 362 trainer requirement, also used the non-afterburning Adour engine. Other applications include the McDonnell Douglas T-45 Goshawk, the Mitsubishi T-2, and the Mitsubishi F-1.Sekigawa 1980, p. 130.

Avionics

From the outset the Jaguar was equipped with a navigation and attack system. While A versions had a reliable double gyroscopic system and a Doppler radar derived from the Mirage IIIE, the GR1s had a totally new digital system with an inertial navigation system and a heads-up display, plus a LRMTS (Laser Ranging and Marked Targeting System) in the nose. These systems were a step above the current technology of the time, but reliability was quite low.

There were many more systems added with the time, like the Atlis II in the French aircraft, and, in 1994–95, some GR1s had laser-designator systems fitted. Missiles like AS-30 and the anti-ship Sea Eagle were added. Some IAF aircraft had the Agave radar system, purposely for maritime strike. India later developed the DARIN system in its Jaguar fleet, with a modern 1553 databus.

Although in operational theatres such as the Gulf War the Jaguar proved to be mechanically more reliable than the Panavia Tornado, the aircraft's avionics were a hindrance to conducting missions.Donald and Chant 2001, p. 34. Owing to the Jaguar A's shortcomings in navigation and target acquisition, French Jaguars had to be escorted by Mirage F1CR reconnaissance aircraft to act as guides. The Jaguar provided a valuable component of the campaign, the RAF detachment of 12 Jaguars flew 612 combat sorties, with no aircraft lost.Jackson 1992, p. 93.

Significant changes were made both during and shortly after the war. Owing to obsolete navigational systems being unable to provide the accuracy required, both French and British Jaguars were quickly modified with Global Positioning System (GPS) receivers, a recent technology at the time.Russell and Hasik 2002, p. 151. Prior to Operation Deliberate Force, the 1995 NATO bombing campaign in Bosnia and Herzegovina, a dozen Jaguars were upgraded with the capability to carry the TIALD laser designator pod and redesignated ''Jaguar GR1B'' or ''T2B'' respectively.Lake ''Air International'' October 1997, pp. 226–228. Shortly afterwards, the RAF upgraded its Jaguar fleet to a common standard, incorporating TIALD and the ability to use new reconnaissance pods. The interim GR3 (''Jaguar 96'') upgrade added a new HUD, a new hand controller and stick top, integrated GPS and TERPROM Terrain Referenced Navigation.Barrie ''Flight International'' via ''flightglobal.com,'' 8–14 April 1998, pp. 30–32.Lake ''Air International'' November 1997, pp. 274–276. The further upgraded ''Jaguar GR3A'' introduced the new EO GP1 (JRP) digital reconnaissance pod, a helmet-mounted sight, improved cockpit displays, a datalink, and improved night vision goggles compatibility.Lake ''Air International'' December 2000, pp. 359–360.

A single 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 manoeuvrability and the test data was used in the development of the Eurofighter.

Operational history

France

The French Air Force took delivery of the first production Jaguar in 1973, one of an eventual 160 single-seat ''Jaguar A''s. For type conversion training, France also took 40 of the two-seat ''Jaguar E''. While the Jaguar was capable of carrying a single AN-52 nuclear bomb, the French government did not assign any Jaguars for use in the ''Force de frappe'', France's strategic nuclear deterrent. Nuclear armed Jaguars were instead assigned the "Pre-Strategic" role, to clear a path for the Strategic strike force.Jackson 1992, pp. 80, 100. The AN-52 nuclear bomb was retired from service in September 1991, when the formerly nuclear-armed squadrons of Escadre de Chasse 7 then concentrated on conventional attack. French Jaguars also performed in the role of Electronic Counter Measures (ECM) aircraft, bearing the Martel anti-radiation missile, capable of staying airborne to suppress enemy defences for long periods of time through mid air refuelling.Glenn 2005, p. 8.

In French service, the Jaguar was frequently deployed in defence of national interests in Africa during the 1970s, a policy sometimes referred to as "Jaguar diplomacy" (''la diplomatie du Jaguar'').de Lespinois, Jérôme
"La diplomatie aérienne: The new gunboat diplomacy" (in French).
''Penser les Ailes françaises,'' Issue 24, 2010/2011. Retrieved: 19 January 2011. Jaguars made their combat debut against Polisario Front forces in Mauritania in December 1977, as part of Opération Lamantin.Taylor 1980, p. 105.Forget, Michel

''Revue historique des armées,'' January 1992. Retrieved: 19 January 2011. In August 1978 a conventionally armed rapid reaction squadron was established, intended to deploy in support of French forces and interests anywhere in the world.

France had been involved in the conflict in Chad for many years, and 2,000 men of the ''Force d'Intervention'' along with helicopters and Jaguars were deployed to defend central Chad in 1978; further forces arrived later as part of Opération Tacaud. The Jaguars were engaged in May and June 1978, contributing significantly in halting an offensive by Goukouni Oueddei's FROLINAT forces, who were routed. One aircraft was shot down, but the pilot was recovered by helicopter.de Lespinois, Jérôme

''Penser les Ailes françaises,'' Issue 6, June 2005, pp. 65–74. Retrieved: 19 January 2011.

In support of the further military action in the region, known as Operation Manta, Jaguars were deployed to Bangui, Central African Republic, in 1983, before being rebased inside Chad at N'Djamena International Airport. On 25 January 1984, Jaguars attacked a rebel column that was withdrawing after raiding the town of Zigey. One aircraft was shot down and the pilot, Captain Michel Croci, was killed. The "Manta" forces were withdrawn in 1984, as part of a de-escalation agreement, whereby both Libyan and French forces were to be withdrawn from Chad. The Libyans did not respect the agreement, and Jaguars returned to Chad in 1986, as part of Operation Epervier, this time with a more forceful role. On 16 February 1986, 11 Jaguars, escorted by Mirage F1 fighters and supported by C-135F tankers and Breguet Atlantic aircraft, launched a raid on the airfield at Wadi Doum, which the Libyans had constructed in Northern Chad, using BAP-100 anti-runway bombs. In response to Libyan incursions, another strike was carried out on 7 January 1987, when a Jaguar destroyed a Libyan radar with a Martel missile. The Jaguars stationed at Ndjamena were a target for Libyan sabotage owing to their effectiveness against enemy forces, but the attempts were unsuccessful.

Persian Gulf War

France committed military assets to the Gulf War coalition; in October 1990, eight Jaguar A aircraft along with several Mirage F1CR reconnaissance aircraft were sent to the Middle East. The Mirages, which had more advanced avionics, acted as guides for the Jaguars.Donald and Chant 2001, pp. 39–40. Owing to obsolete navigational systems being unable to provide the accuracy required, both French and British Jaguars were quickly modified with GPS receivers, RAF Tornados also required adaption to a lesser extent. The French Jaguar force in Saudi Arabia built up to a maximum of 28 aircraft, which carried out 615 combat sorties, with one Jaguar damaged by an Iraqi surface-to-air missile.Jackson 1992, p. 92. Typical targets were Iraqi armoured units, Scud missile sites, and naval vessels.

On 17 January 1991, 12 French Jaguars bombed Ahmad al-Jaber Air Base, Kuwait; three were damaged in the attack but all returned to base. On 26 January, RAF Jaguars and Tornados raided several Silkworm missile batteries in Kuwait to encourage the perception of an imminent amphibious invasion to liberate the country.Glenn 2005, p. 41. On the 30th, two RAF Jaguars destroyed a ''Polnochny''-class landing ship with rockets and cannon. The Iraqi Republican Guard, entrenched on the Kuwait-Saudi border, were subjected to a continuous intensive bombing campaign for weeks to demoralise them, allied Jaguars forming a portion of the delivering aircraft.Glenn 2005, p. 44. The Jaguars also performed valuable reconnaissance of the combat area for Coalition forces. Both nations' Jaguars were withdrawn from the region in March 1991, at the end of Desert Storm.

Subsequent Operations

In Operation Deliberate Force in 1995, six Jaguars based in Italy conducted 63 strike missions. The last Jaguars in French service were retired in 2005, being replaced in the ground attack roles by the Dassault Rafale.

United Kingdom

The RAF accepted delivery of the first of 165 single seat ''Jaguar GR1''s (the service designation of the ''Jaguar S'') with 54(F) squadron in 1974. These were supplemented by 35 two seat trainers, the ''Jaguar T2'' (previously ''Jaguar B''). The Jaguar S and B had a more comprehensive nav/attack system than the A and E models used by the French Air Force, consisting of a Ferranti/Marconi NAVWASS (NAVigation and Weapon Aiming Sub System) and a Plessey 10 Way Weapon Control System. RAF Jaguars were used for rapid deployment and regional reinforcement, and others flew in the tactical nuclear strike role, carrying the WE.177 bomb.Cirincione et al. 2005, p. 199.

Beginning in 1975 with 6 Squadron, followed by 54 Squadron based at RAF Coltishall, and a 'Shadow squadron', 226 OCU based at RAF Lossiemouth, Jaguar squadrons were declared operational to SACEUR with the WE.177. 14 Squadron and 17 Squadron based at RAF Bruggen followed by 1977. 20 Squadron and 31 Squadron also based at RAF Bruggen brought the RAF Jaguar force to its peak strength of six squadrons plus the OCU, each of twelve aircraft equipped with eight WE.177s. Two further squadrons, 2 Squadron and 41 Squadron based at RAF Laarbruch and RAF Coltishall respectively, were primarily tasked with tactical reconnaissance.Wagner 2009, p. 124. From 1975 the OCU's wartime role was as an operational squadron in the front line assigned to SACEUR with 12 Jaguar aircraft, eight WE.177 nuclear bombs, and a variety of conventional weapons.

In April 1975, a single Jaguar was used to test the aircraft's rough airstrip capacity, by landing and taking off multiple times from the M55 motorway, the final test flight was conducted with a full weapons load; the ability was never used in service but was considered useful as improvised runways might be the only runways left available in a large scale European conflict.Glenn 2005, p. 19. In a high intensity European war, the role of the Jaguar was to support land forces on the continent in resisting a Soviet assault on Western Europe, striking targets beyond the forward edge of the battlefield should a conflict escalate. The apparent mismatch between aircraft numbers and nuclear bombs was a consequence of RAF staff planners concluding that there would be one third attrition of Jaguars in an early conventional phase, leaving the survivors numerically strong enough to deliver the allocated stockpile of 56 nuclear bombs."WE.177 Carriage."
''nuclear-weapons.info.'' Retrieved: 15 November 2010.

From December 1983, 75 Jaguar GR1s and 14 T2s were updated to the GR1A and T2A standards with FIN1064 navigation and attack systems replacing the original NAVWASS. At about the same time, most were also re-engined with Adour 104 engines and were fitted with the ability to carry Sidewinder air to air missiles or AN-ALQ-101(V)-10 electronic countermeasures pods under the wings.

The RAF Jaguar force was altered in late 1984, when 17 Squadron, 20 Squadron and 31 Squadron exchanged their Jaguars for Tornado GR1s, although their assignment to SACEUR and their wartime role remained unchanged. The two other RAF Germany units, 14 Squadron and 2 Squadron, followed suit in 1985 and 1989 respectively, which left the operational Jaguar force concentrated in 6, 41 and 54 Squadrons at RAF Coltishall.

1990 Gulf War

Following the Iraqi invasion of Kuwait, on 9 August 1990 the British government assigned an initial 12 Jaguar GR1A and 12 Tornado F3 aircraft to the Middle East in Operation Granby, these aircraft operated from bases in Oman and Bahrain. On 23 August 1990, a squadron of Tornado GR1 interdictors were dispatched to the region as well, but the Tornado GR1 was difficult to keep operational in the high temperatures. Blackburn Buccaneers were dispatched in January 1991 to act as laser designators for the ground strike aircraft.Donald and Chant 2001, p. 35. The RAF's Jaguars gained several new weapons during the Persian Gulf War, including CRV7 high-velocity rockets and American CBU-87 cluster bombs which were used because the RAF's existing BL755 bombs were designed for low-level release, and therefore unsuitable for higher-altitude operations common over the Persian Gulf. The RAF's detachment of 12 Jaguars flew 612 combat sorties, with no aircraft being lost. ''XZ364'' "Sadman" flew 47 missions; the highest number of missions of any aircraft.

Subsequent upgrades

In 1994, in order to meet an urgent need to increase the number of aircraft able to designate targets for laser-guided bombs, 10 GR1As and two T2As were upgraded with the capability to carry the TIALD laser designator pod and redesignated as ''Jaguar GR1B'' and ''T2B'' respectively. TIALD equipped Jaguar GR1Bs were deployed to Italy in August to take part in Operation Deliberate Force against Bosnian Serb forces, being used to designate targets for RAF Harriers.Lake ''Air International'' October 1997, p. 228. During the Bosnian operations, a Jaguar of 41 Squadron carried out the first RAF bombing raid in Europe since the end of the Second World War fifty years before."41 Squadron."
''Royal Air Force,'' 2011. Retrieved: 16 January 2011.

Following the success of the GR1B/T2B upgrade, the RAF launched a plan to upgrade its Jaguar fleet to a common standard, incorporating improvements introduced to some aircraft during the Gulf War, together with adding the ability to use TIALD and new reconnaissance pods. The upgrade came in two parts; the interim GR3 (''Jaguar 96'') upgrade added a new HUD, a new hand controller and stick top, integrated GPS and TERPROM Terrain Referenced Navigation. It was delivered in two standards, for recce and TIALD. The further upgraded ''Jaguar GR3A'' (also known as ''Jaguar 97'') introduced fleet-wide compatibility with TIALD and the new EO GP1 (JRP) digital reconnaissance pod, a helmet mounted sight, improved cockpit displays, a datalink, and improved night vision goggles compatibility. All GR3As were subsequently re-engined with the new Adour 106 turbofan.Thomas, Geoff

The Jaguars did not see service in the 2003 Iraq War; they had been planned to operate from bases in Turkey, to the north of Iraq, but Turkey refused access to its airbases and the northern attack was cancelled.

Demands by the UK Treasury to cut the defence budget led to Defence Secretary Geoff Hoon detailing plans on 21 July 2004 to withdraw the Jaguar by 2007. An expected out of service date of October 2007 was brought forward at just five days notice to 30 April 2007. On 20 December 2007, a Jaguar operated by QinetiQ undertook the last British military Jaguar flight.

Following their retirement from flying service, many Jaguars continue to serve as ground instructional airframes, most notably at RAF Cosford, used in the training of RAF fitters.

India

India had been approached as a possible customer for the Jaguar as early as 1968, but had declined, partly on the grounds that it was not yet clear if the French and British would themselves accept the aircraft into service. India had already its Marut fighter-bomber, and tried to upgrade it with new engines, until the new project collapsed. A decade later IAF would become the largest single export customer, with a $1 billion order for the aircraft in 1978, the Jaguar being chosen ahead of the Dassault Mirage F1 and the Saab Viggen after a long and difficult evaluation process.Barua 2005, p. 274.''Air International'' October 1988, pp. 177–181. The order involved 40 Jaguars built in Europe at Warton, and 120 licence-built aircraft from Hindustan Aeronautics Limited (HAL) under the local name '' Shamsher'' ("Sword of Justice").

As an interim measure, 18 RAF Jaguars were loaned to the IAF with the first two loaned aircraft operational with Western Air Command on 27 July 1979.Green et al. 1982, p. 16. The second batch of aircraft for the IAF were 40 Jaguar Internationals built at Warton, the first aircraft being delivered in March 1981.Jackson 1992, p. 108. Batch Three was the assembly of another 45 aircraft by HAL of kits shipped from the United Kingdom, the first kit being shipped to India in May 1981. In the following phases more aircraft would be built in India with less European content. A total of 80 aircraft were built by HAL.

Indian Jaguars were quite different from the RAF ones. The Adour Mk 811 engines were soon adopted in the HAL production line (the previous Jaguars made in UK had the earlier Mk 804), giving 8,400 lbf each. There were R-550 Magic 1 or 2 in rails over the wings. But more importantly, the NAWASS, even if very modern in conception, was replaced because it was found quite unreliable. The RAF was already upgrading the system with the modern Ferranti Type 1024 INS, but India was offered the 1024E export, less powerful version. So IAF instead pursued the development of new nav-attack system, called DARIN, that combined several technologies from France, UK and other sources. This system was more reliable and more precise than the older NAWASS and all the IAF Jaguars had it as standard. The Jaguar was found to be a long-range, fast, stable and effective strike aircraft in IAF service. Another important upgrade was the Maritime Strike version, fitted with a radar (the French Agave) and powerful British anti-ship missiles, produced in a very limited number (12). The only real issue with Jaguar is the lack of power at altitude, especially with heavy ordnance on board.

Indian Jaguars were used to carry out reconnaissance missions in support of the Indian Peace Keeping Force in Sri Lanka between 1987 and 1990. They later played an active role in the 1999 Kargil War with Pakistan, dropping both unguided and laser-guided bombs, the IAF defining its role as a "deep penetrating strike aircraft". The Jaguar is also used in small numbers for the anti-ship role, equipped with the Sea Eagle missile.Eden 2004, pp. 400–401.Barua 2005, p. 378. The Jaguar remains an important element of the Indian military as, along with the Mirage 2000, the Jaguar has been described as one of the few aircraft capable of performing the nuclear strike role with reasonable chances of success. It has been alleged that the Indian military decided against developing the Jaguar into an active nuclear platform because of its lack of ground clearance for deploying India's gravity-dropped nuclear bombs.

As the aircraft aged, the avionics were viewed as lacking suitable components for the ground attack mission, such as terrain-following radar, GPS navigation or modern night-flight systems; consequently, several upgrades were carried out in the mid-1990s, including the addition of the Litening targeting pod. India placed an order for 17 additional upgraded Jaguar aircraft from Hindustan Aeronautics in 1999 and a further 20 in 2001–2002.Wilson and McBride 2009, p. 68. The IAF plans to upgrade up to 125 Jaguars starting in 2013 by upgrading the avionics (including multi mode radar, auto-pilot and other changes) as part of the DARIN III programme and is considering fitting more powerful engines, Honeywell F125IN, to improve performance, particularly at medium altitudes.Wilson and McBride 2009, p. 71.
The latest upgrade program DARIN III (Display Attack Ranging Inertial Navigation) has also been approved. In addition to new avionics and equipment installed as part of DARIN II upgrade, DARIN III would feature modified avionics architecture, new cockpit with dual SMD, solid state flight data recorder and solid state video recording system, auto pilot system, integration of new multi-mode radar on Jaguar IS (currently only Jaguar IM are fitted with radars). Major structural modification would be carried out on the air frame to accommodate the radar. Initial Jaguars delivered to the IAF were powered by two Adour 804E; further deliveries were powered by Adour Mk811. All the current IAF Jaguars are powered by Adour Mk811. DARIN III upgrade will cause additional weight problems due to addition of new avionics and radar, resulting in it becoming underpowered. Later IAF took decisions not to upgrade the engines
due to budget problems. As part of technology transfer agreement with Israeli Aerospace Industries (IAI) for 54 EL/M-2052 AESA radar to be manufactured by HAL Avionics Division, the first production version will be ready by March 2021 to be fitted on Jaguar IS as part of DARIN III UPG standard.

In 2018, India cannibalised 31 airframes purchased from France, 2 airframes from UK and Oman each, few engines and several hundred types of critically needed spares for optimum squadron serviceability.

Other operators

In 1969, while still in the prototype stage of development, formal approaches had been made to Switzerland, India, Japan, Australia, the Netherlands, Belgium, and Germany, promoting the aircraft for sale.''Flight'' 16 October 1969, p. 604. Japan began negotiations towards licensed production of the Jaguar,Lake 1994, p.139. but these plans failed in part because of the high royalty payments sought by SEPECAT. A proposal for Turkey to construct Jaguars under licence also did not come to fruition.Segell 1998, p. 168. Kuwait initially ordered 50 Jaguars and 16 Mirage 5s, but instead chose F1s.Eden 2004, p. 398. Pakistan approached SEPECAT after the US refused to sell their aircraft of choice, the LTV A-7 Corsair II, due to an arms embargo; Pakistan eventually opted for Mirage 5s.

Jaguars were successfully sold to a number of overseas countries, India being the largest operator. The ''Jaguar International'' was an export version which was sold to Ecuador, Nigeria and Oman. The Ecuadorian Air Force, the only Latin American export customer, purchased 10 single- and 2 two-seat variants, officially designated ''Jaguars ES'' and ''EB'', respectively. The first of twelve aircraft arrived in January 1977. They were used mainly for ground attack roles and occasionally for air superiority duties during the Cenepa War with Peru in 1995, but the main part of the fleet was held in reserve in case of a wider conflict with the Peruvians. Nigeria ordered 13 single-seat ''SN'' and 5 two-seat ''BN'' variants; SEPECAT delivered the first of these in May 1984. A subsequent order for an 18-aircraft second batch was cancelled. Some of those in service were withdrawn from operations on the grounds of economy, with the remaining aircraft put up for re-sale. The Royal Air Force of Oman ordered 10 single-seat and 2 two-seat variants, designated ''Jaguars OS'' and ''OB'', respectively; the first was delivered in March 1977. A second identical 12-aircraft order was placed in the mid-1980s; these were joined by two secondhand Indian and RAF examples. The last of the Omani aircraft were retired on 6 August 2014.Oman retires last Jaguar strike aircraft
