History
The initial members of the consortium were the United Kingdom, France, Germany, Italy, and Spain. In 1985 France withdrew in favour of its own Avion de Combat Exp?rimental (ACX) project (which later became the Dassault Rafale).

Initial hardware requirements were as follows: UK 250, Germany 250, Italy 165, and Spain 100. Production work share was divided among the countries proportionally to procurement: British Aerospace (33%), Daimler-Benz (33%), Aeritalia (21%), and Spain's CASA (13%).

Over the next five years, design work continued, aided by data from the British Aerospace EAP prototype which had first flown in August, 1986. The maiden flight of the Typhoon prototype took place on March 27, 1994 (then just known as the Eurofighter EF 2000). Messerschmitt-B?lkow-Blohm chief test pilot Peter Weger took the prototype on a test flight around Bavaria. The 1990s saw significant arguments over work share, the specification of the aircraft and even participation in the project.

When the final production contract was signed, revised procurement totals were as follows: UK 232, Germany 180, Italy 121, and Spain 87. Production was again allotted according to procurement: British Aerospace (37%), DASA (29%), Aeritalia (19.5%), and CASA (14%).

Development is now the responsibility of Eurofighter Jagdflugzeug GmbH, based in Munich and wholly owned by BAE Systems (formerly British Aerospace) in the UK, Alenia Aerospazio in Italy, and the EADS Deutschland Aerospace Group (formerly DaimlerChrysler, in conjunction with Deutsche Aerospace AG) and EADS Spain (formerly CASA).

On July 2, 2002, the Austrian government announced the decision to buy the Typhoon as its new air defence aircraft. The contract was not signed at that time, however, due to floods, an election, and political controversy. The purchase of 18 Typhoons was finalized on July 1, 2003. The cost was €1,959,000,000 and included 18 aircraft, training for pilots and ground crew, logistics, maintenance, and a simulator. The full, "fly-away" price of a single Typhoon works out to €62,900,000.

The project has been named and renamed a number of times since its inception, having been known as EFA (European Fighter Aircraft), Eurofighter, EF2000 (Eurofighter 2000), and most recently Typhoon.


Production
The Eurofighter Typhoon is unique in modern combat aircraft in that there are four separate assembly lines (the F-16 was only produced internationally under limited licences). Each partner company assembles its own national aircraft, but builds the same parts of all 620 aircraft.


Inventory
Despite many delays and controversies over cost, the Typhoon is now in series production.

In British service, the aircraft is supposed to replace the Tornado F3 and the Jaguar GR3A.

The Tornados will be replaced from 2006-2010, and the Jaguars from 2010-2014. Initial deliveries of the Typhoon to the RAF have begun. The first unit to form was an Operational Evaluation Unit, No. 17 Sqn in 2003, followed by the Operational Conversion Unit, 29 Sqn at BAE Warton in 2004. The aircraft are expected to move to RAF Coningsby in 2005. The initial designations for the RAF aircraft are T1 for the two-seater trainer, and F2 for the single-seater operational fighter.

An extensive overseas sales effort has so far yielded an order from Austria for 18 units, and an initial interest from Greece for 60 aircraft. Norway has also expressed interest, but has yet to buy any Eurofighters. Other countries expressing interest include South Africa, Chile, Brazil, Saudi Arabia and Turkey.

The Typhoon could possibly meet the requirements of the UK's Future Offensive Air System programme, which is seeking to replace the deep-strike capability provided by the Tornado GR4. If selected, the Typhoon would likely be modified for internal weapons carriage and increased internal fuel capacity.


Combat Performance

German Chancellor Gerhard Schr?der with a new Luftwaffe EurofighterFor a detailed comparison of the Typhoon and other fighters see: Comparison of 2000s fighter aircraft.

The Typhoon's combat performance, particularly compared to the upcoming F/A-22 Raptor and F-35 fighters under development in the United States and the Dassault Rafale developed in France, has been the subject of some speculation. While making a complete assessment is impossible on publicly available information, there is a study by DERA comparing the Typhoon to other contemporary fighters.

In June 2005, The Scotsman reported (http://scotlandonsunday.scotsman.com/uk.cfm?id=673262005) that, in a mock confrontation with two American F-15 fighter craft, the Eurofighter was not only able to avoid his pursuers, he succeeded in getting into shooting position. Unattributed statements indicate that the success of the craft came as a surprise to both the Americans and the RAF.

While the Typhoon lacks the all-aspect stealth technology of the F/A-22, the design does incorporate many low-observable features, resulting in a much smaller radar cross-section than earlier fighters. It is also capable of sustained supersonic cruise without using afterburners. The F/A-22 is the only other fighter with supercruise capabilities.

According to EADS, the maximum speed possible without reheat is Mach 1.5 (although this drops to Mach 1.3 with an air-to-air weapons load).


Problems
As German newspapers reported in 2004, the few Eurofighters in service with the Luftwaffe did not meet specifications at that time. Because of technical difficulties, the aircraft is only allowed to take off without cannon ammunition and at moderate temperatures. However, it is important to note that early aircraft are delivered at a baseline state, with capability to be increased incrementally; indeed, BAE has stated that the capability of the aircraft will increase at a faster rate than the training of pilots.

Development timeline
1972
RAF issues Air Staff Target 396 (AST-396), a requirement for a STOVL aircraft to replace the Harrier and Jaguar fleets.
AST-403, specification revised for an air superiority fighter. STOVL requirement dropped and AST-409 lead to the development of Harrier GR5.
Mid-1970s
France, Germany and UK initiate the European Combat Aircraft programme (ECA).
1979
Following differing requirements (particularly French requirement for carrier compatibility,) BAe and MBB propose the European Combat Fighter (ECF)
1981
Development of different national prototypes and continued differences over specification lead to cancellation of ECF programme.
Panavia partners (Germany, Italy and UK) launch Agile Combat Aircraft (ACA) programme. Following failure of Germany and Italy to fund development the UK MoD pays ?80m prototype, the European Aircraft Programme (EAP.)
1983
May - Contract for production of EAP prototype signed.
Britain, France, Germany, Italy and Spain launch Future European Fighter Aircraft (F/EFA) programme. Aircraft to have Short Take Off and Landing (STOL) and Beyond Visual Range (BVR) capabilities.
1984
France reiterates requirement for carrier capable version and demands 50% workshare. Britain, Germany and Italy opt out and establish new EFA programme
1985
France officially withdraws, commences ACX project.
October 27 - EAP demonstrator rolled out at BAe Warton.
1986
June - Eurofighter GmbH established.
August 8 - EAP makes its first flight. Configuration closely matches final Eurofighter design.
Rolls-Royce, MTU Aero Engines, FiatAvio (now Avio) and ITP form EuroJet Turbo GmbH for development of EJ200.
1988
November 23 - Contracts signed for production of demonstrator engines and airframes.
1990
CAPTOR RadarEuroRADAR formed for development of ECR-90 (CAPTOR) radar (right).
1991
May 1 - Last flight of EAP demonstrator.
1992
EuroDASS formed for development of Defensive Aids Sub System (DASS.) Initially only UK and Italy participate. When Eurofighter enters service only RAF aircraft will exploit all capabilities of DASS.
July - Germany announces intention to withdraw from the project. Negotiations begin to reduce costs. As a single engine aircraft is ruled out Germany decides to fit cheaper systems, e.g., F/A-18's APG-65 in place of ECR-90, and delay its service entry by two years. Germany eventually participates in all systems.
December - Renamed Eurofighter 2000.
1994
March 27 - Maiden flight of first development aircraft, DA1 from DASA at Manching with RB199 engines.

January - First aerial refuelling trials, involving DA2 and an RAF VC10 tanker.
January 30 - NETMA and Eurofighter GmbH sign production and support contracts for 620 aircraft.
September - Typhoon name adopted, announced as strictly for export contracts. There is some controversy (http://news.bbc.co.uk/1/hi/uk/163092.stm) as the last aircraft to bear the name was the Hawker Typhoon, a World War II aircraft.
