The Eurojet EJ200 is a military turbofan, used as the powerplant of the Eurofighter Typhoon. The engine is largely based on the Rolls-Royce XG-40 technology demonstrator which was developed in the 1980s. The EJ200 is built by the EuroJet Turbo GmbH consortium.

Rolls-Royce began development of the XG-40 technology demonstrator engine in 1984.[1] Development costs were met by the British government (85%) and Rolls-Royce.[2]
On 2 August 1985, Italy, West Germany and the UK agreed to go ahead with the Eurofighter. The announcement of this agreement confirmed that France had chosen not to proceed as a member of the project.[3] One issue was French insistence that the aircraft be powered by the SNECMA M88, in development at the same time as the XG-40.[4]
The Eurojet consortium was formed in 1986 to co-ordinate and manage the project largely based on XG-40 technology. In common with the XG-40, the EJ200 has a three-stage fan with a high pressure ratio, five-stage low-aspect-ratio high-pressure (HP) compressor with active tip-clearance control, a combustor using advanced cooling and thermal protection, and single-stage HP and low-pressure (LP) turbines with PM discs and low-density single crystal blades."[5] A reheat (i.e., afterburner) system provides thrust augmentation. The variable area final nozzle is a convergent-divergent design. Unusually for an advanced military turbofan, the fan lacks variable stagger inlet guide vanes.
In December 2006, Eurojet completed deliveries of the 363 EJ200s for the Tranche 1 Eurofighters. Tranche 2 aircraft require 519 EJ200s.[6] As of December 2006[update], Eurojet was contracted to produce a total of 1,400 engines for the Eurofighter project.[7]
In 2009, Eurojet entered a bid, in competition with General Electric’s F414, to supply a thrust vectoring variant of the EJ200 to power the HAL Tejas.

The EJ200 Eurofighter-Typhoon jet engine is one of three engines hosted in one vehicle for a new attempt at the land speed record. The Eurofighter's jet engine delivers 90 kN of thrust that will enable the vehicle called the Bloodhound SSC to move 8 km in 100 seconds.[9]
