The Panavia Tornado is a family of twin-engine, variable-sweep wing combat aircraft, which was jointly developed and manufactured by Italy, the United Kingdom, and West Germany. There are three primary Tornado variants; the Tornado IDS (interdictor/strike) fighter-bomber, the suppression of enemy air defences Tornado ECR (electronic combat/reconnaissance) and the Tornado ADV (air defence variant) interceptor aircraft.
The Tornado was developed and built by Panavia Aircraft GmbH, a tri-national consortium consisting of British Aerospace (previously British Aircraft Corporation), MBB of West Germany, and Aeritalia of Italy. It first flew on 14 August 1974 and was introduced into service in 1979–1980. Due to its multirole nature, it was able to replace several different fleets of aircraft in the adopting air forces. The Royal Saudi Air Force (RSAF) became the only export operator of the Tornado in addition to the three original partner nations. A tri-nation training and evaluation unit operating from RAF Cottesmore, the Tri-National Tornado Training Establishment, maintained a level of international co-operation beyond the production stage.
The Tornado was used by the Royal Air Force (RAF), Italian Air Force and RSAF during the 1991 Gulf War, in which the Tornado conducted many low-altitude penetrating strike missions. The Tornados of various operators were also used in conflicts in the former Yugoslavia during the Bosnian War and Kosovo War, the Iraq War, Libya during the Libyan civil war, as well as smaller roles in Afghanistan and Yemen. Including all variants, 992 aircraft were built.
In 1968, West Germany, the Netherlands, Belgium, Italy and Canada formed a working group to examine replacements for the Lockheed F-104 Starfighter, initially called the Multi Role Aircraft (MRA), later renamed as the Multi Role Combat Aircraft (MRCA). The participating nations all had ageing fleets that required replacing; but, as the requirements were so diverse, it was decided to develop a single aircraft that could perform a variety of missions that were previously undertaken by a fleet of different aircraft. Britain joined the MRCA group in 1968, represented by Air Vice-Marshal Michael Giddings, and a memorandum of agreement was drafted between Britain, West Germany, and Italy in May 1969.
By the end of 1968, the prospective purchases from the six countries amounted to 1,500 aircraft. Canada and Belgium had departed before any long-term commitments had been made to the programme; Canada had found the project politically unpalatable; there was a perception in political circles that much of the manufacturing and specifications were focused on Western Europe. France had made a favourable offer to Belgium on the Dassault Mirage 5, which created doubt as to whether the MRCA would be worthwhile from Belgium’s operational perspective.
On 26 March 1969, four partner nations – United Kingdom, Germany, Italy and the Netherlands, agreed to form a multinational company, Panavia Aircraft GmbH, to develop and manufacture the MRCA. The project’s aim was to produce an aircraft capable of undertaking missions in the tactical strike, reconnaissance, air defence, and maritime roles; thus allowing the MRCA to replace several different aircraft then in use by the partner nations. Various concepts, including alternative fixed-wing and single-engine designs, were studied while defining the aircraft. The Netherlands pulled out of the project in 1970, citing that the aircraft was too complicated and technical for the RNLAF‘s preferences, which had sought a simpler aircraft with outstanding manoeuvrability. An additional blow was struck by the German requirement reduced from an initial 600 aircraft to 324 in 1972.
At the conclusion of the project definition phase in May 1970, the concepts were reduced to two designs; a single seat Panavia 100 which West Germany initially preferred, and the twin-seat Panavia 200 which the RAF preferred and which would become the Tornado. The aircraft was briefly called the Panavia Panther, the project soon coalesced towards the two-seat option. In September 1971, the three governments signed an Intention to Proceed (ITP) document, at which point the aircraft was intended solely for the low-level strike mission, where it was viewed as a viable threat to Soviet defences in that role. It was at this point that Britain’s Chief of the Defence Staff announced “two-thirds of the fighting front line will be composed of this single, basic aircraft type”.
Prototypes and testing
The first of more than a dozen Tornado prototypes took flight on 14 August 1974 at Manching, Germany; the pilot, Paul Millett stated of the incident: “Aircraft handling was delightful… the actual flight went so smoothly that I did begin to wonder whether this was not yet another simulation”. Flight testing led to the need for minor modifications. Airflow disturbances were responded to by re-profiling the engine intakes and the fuselage to minimise surging and buffeting experienced at supersonic speeds. Testing revealed that a nose-wheel steering augmentation system, connecting with the yaw damper, was necessary to counteract the destabilising effect produced by deploying the thrust reverser during landing rollouts. In August 1976, Soviet espionage activities were exposed trying to obtain information on the aircraft.
Two prototypes were lost in accidents, both of which had been primarily caused by poor piloting decisions and errors leading to two ground collision incidents; a third Tornado prototype was seriously damaged by an incident involving pilot-induced pitch oscillation. The Tornado made use of relatively new electronic technologies to stabilise the aircraft’s flight and augment its flight envelope, known as active control technology or fly-by-wire (FBW); thus several older aircraft types were extensively converted and rebuilt for testing to establish the concept’s validity. In the late 1970s, British Aerospace developed a technology demonstration aircraft, a converted SEPECAT Jaguar, equipped with a full-authority digital flight control system, with progressive changes to the airframe to showcase the system’s ability to compensate for aerodynamic irregularities and imbalances; MBB also flew a converted demonstrator aircraft, a Lockheed F-104G Starfighter, which similarly compensated for instability via a digital flight control system. Experience from both of these programmes would influence the Tornado, and to a greater extent, the later Eurofighter Typhoon.
Export customers were sought after West Germany withdrew its objections to exporting the aircraft; Saudi Arabia was the only export customer of the Tornado The agreement to purchase the Tornado was part of the controversial Al-Yamamah arms deal between BAE Systems and the Saudi government. Oman had committed to purchasing Tornados and the equipment to operate them for a total value of £250 million in the late 1980s, but cancelled the order in 1990 due to financial difficulties.
During the 1970s, Australia considered joining the MRCA programme to find a replacement for their ageing Dassault Mirage IIIs; ultimately the McDonnell Douglas F/A-18 Hornet was selected to meet the requirement. Canada similarly opted for the F/A-18 after considering the Tornado. Japan considered the Tornado in the 1980s, along with the General Dynamics F-16 Fighting Falcon and F/A-18; before selecting the Mitsubishi F-2, a domestically produced design based on the F-16. In the 1990s, both Taiwan and South Korea expressed interest in acquiring a small number of Tornado ECR aircraft. In 2001, EADS proposed a Tornado ECR variant with a greater electronic warfare capability for Australia.
Production came to an end in 1998; the last batch of aircraft being produced going to the Royal Saudi Air Force, who had ordered a total of 96 IDS Tornados. In June 2011, it was announced that the RAF’s Tornado fleet had flown collectively over one million flying hours. Aviation author John Lake noted that: “The Trinational Panavia Consortium produced just short of 1,000 Tornados, making it one of the most successful postwar bomber programs”. In 2008, AirForces Monthly said of the Tornado: “For more than a quarter of a century… the most important military aircraft in Western Europe.”
