Eurojet EJ200 — Aircraft Engine
Open in interactive gallery →

The Eurojet EJ200 is the afterburning low-bypass turbofan that powers the Eurofighter Typhoon. Built by Eurojet Turbo GmbH — a four-nation consortium of Rolls-Royce (UK), MTU Aero Engines (Germany), Avio Aero (Italy), and ITP Aero (Spain) — the engine emerged from Rolls-Royce's XG-40 demonstrator programme of the 1980s and entered Typhoon service in 2003. Each Typhoon carries two EJ200s, each delivering around 13,500 lbf dry and 20,250 lbf with full reheat.

The architecture is deliberately compact: a single-stage wide-chord fan, a five-stage high-pressure compressor, an annular combustor, single-stage HP and single-stage LP turbines, and a convergent-divergent reheat nozzle. The HP and LP shafts are independent, giving a true two-spool layout despite the short overall length of roughly 4 m. Single-crystal turbine blades and brush seals push the turbine entry temperature beyond 1,800 K. The engine's full-authority digital electronic control (FADEC) runs both engines from common cockpit signals and handles fuel scheduling, surge protection, and health monitoring across the Typhoon's mission spectrum.

Thrust-to-weight ratio is roughly 9:1 — competitive with the General Electric F414 that powers the Super Hornet and Gripen E — and the EJ200 was sized to give the Typhoon supercruise at Mach 1.5 without reheat at altitude, a feature shared only with the F-22 Raptor among in-service Western fighters. Reheat is reserved for combat manoeuvring, take-off, and supersonic acceleration. A thrust-vectoring nozzle, the EJ200 TVN, has been demonstrated on test rigs since the early 2000s but has not been fielded on production Typhoons.

Production is split across the four consortium partners, each building dedicated modules: Rolls-Royce produces the combustor and HP turbine, MTU builds the HP and LP compressors, Avio handles the gearbox and accessories, and ITP manufactures the LP turbine and nozzle. Final assembly takes place at all four sites, with each nation supporting its own Typhoon fleet. By 2026 more than 1,500 EJ200s had been delivered, supporting Typhoon fleets in the United Kingdom, Germany, Italy, Spain, Austria, Saudi Arabia, Oman, Kuwait, and Qatar. The engine has also powered the Bloodhound LSR supersonic land-speed-record car.

Future upgrades centre on the EJ200 Phase 4 Enhancement (P4E), proposed to lift thrust by around 15% and integrate a thrust-vectoring nozzle for the Typhoon's late-life mid-life upgrade. Eurojet has separately demonstrated the EJ230 derivative — a higher-bypass version aimed at long-endurance unmanned applications — and proposed an EJ270 turbofan derivative for the cancelled British FOAS deep-strike requirement. Industrial discussions also link the engine's core technology to the propulsion roadmap for the British-Italian-Japanese GCAP sixth-generation fighter, although GCAP's powerplant is a clean-sheet design led by Rolls-Royce, IHI, and Avio. Until GCAP enters service in the mid-2030s, the EJ200 remains the only European-designed fighter engine still in series production alongside Safran's M88, securing skills and supply chains for the next generation across the four consortium nations.

For Kids — a shorter, friendlier version

The Eurojet EJ200 is a powerful jet engine. It was made by four companies from four different countries. Those companies are Rolls-Royce from Britain, MTU from Germany, Avio from Italy, and ITP from Spain. The engine first flew on the Eurofighter Typhoon in 2003.

The EJ200 powers the Eurofighter Typhoon fighter jet. Each Typhoon carries two of these engines. Together, they give the jet incredible speed and power. The Typhoon can even cruise faster than the speed of sound without using its afterburner!

The engine has a special feature called reheat, or afterburner. This squirts extra fuel into the exhaust to give a huge boost of power. With reheat on, each engine pushes with over 20,000 pounds of force. That is like lifting several large cars off the ground!

Inside the engine, the parts are built to handle extreme heat. Special turbine blades are grown as a single crystal of metal. This makes them very strong at very high temperatures. A smart computer system called FADEC controls the engine and keeps it running safely.

The EJ200 is smaller than many other jet engines with similar power. It is only about 4 meters long, which is shorter than a large family car. Its thrust-to-weight ratio of about 9 to 1 means it is very powerful for its size.

Fun Facts

  • The EJ200 was designed by four companies working together across four countries.
  • Each Eurofighter Typhoon carries two EJ200 engines side by side.
  • With its afterburner on, each engine pushes with more than 20,000 pounds of force.
  • The engine is shorter than a large family car, yet incredibly powerful.
  • The Typhoon can fly faster than the speed of sound even without switching on the afterburner.
  • Turbine blades inside the engine are made from a single crystal of metal to handle extreme heat.
  • A smart computer called FADEC watches over the engine and adjusts it during every part of a flight.
  • The EJ200 is faster than most older jet engines at cruising above the speed of sound — reaching Mach 1 and a half without afterburner!

Kids’ Questions

Who made the EJ200 engine?

Four companies made it together. They are Rolls-Royce from Britain, MTU from Germany, Avio from Italy, and ITP from Spain. They formed a team called Eurojet Turbo GmbH to build the engine.

What is an afterburner?

An afterburner squirts extra fuel into the hot exhaust gases at the back of the engine. This creates a big burst of extra power and thrust. Pilots use it when they need maximum speed.

Why are the turbine blades so special?

Each turbine blade is grown from a single crystal of metal. This makes the blade much stronger when things get extremely hot inside the engine. Normal metal blades would weaken at those high temperatures.

What does FADEC do?

FADEC is a smart computer that controls the engine. It manages fuel flow, protects the engine from damage, and checks the engine's health during flight. It helps keep the pilot safe by making sure the engine always works properly.

Variants

EJ200 (production)
Baseline production engine in service since 2003. Around 13,500 lbf dry / 20,250 lbf with reheat. Powers all Typhoon Tranche 1, 2, and 3 aircraft delivered to the four partner nations and export customers.
EJ200 TVN (demonstrator)
Thrust-vectoring nozzle variant flown on rig and trialled on a Typhoon development airframe in 2004. Nozzle deflects ±20° in pitch and yaw. Never adopted on production Typhoons but the technology remains on the shelf for Phase 4 Enhancement.
EJ200 P4E (proposed)
Phase 4 Enhancement package proposed by Eurojet to lift thrust by around 15%, raise turbine entry temperature, and integrate the TVN nozzle. Targeted at the Typhoon's long-term retention into the 2040s alongside GCAP.
Bloodhound LSR powerplant
A surplus EJ200 (originally a Typhoon flight-test engine) was installed in the Bloodhound supersonic land-speed-record car, providing the air-breathing thrust component alongside a hybrid rocket. The car reached 628 mph in 2019 trials before the programme was paused.

Frequently Asked Questions

How does the EJ200 compare with the F414 that powers the Super Hornet and Gripen E?

Both are 20,000 lbf-class afterburning low-bypass turbofans designed in the same era, and both run FADEC control with single-crystal HP turbine blades. The EJ200 has a slightly higher thrust-to-weight ratio (around 9:1 versus 8.5:1 for the F414) and was sized for Mach 1.5 supercruise in the Typhoon, while the F414 was sized for sustained high-G manoeuvring rather than reheat-free cruise (per the GE Aerospace F414 fact sheet).

Who builds which parts of the EJ200?

Eurojet allocates modules by nation: Rolls-Royce builds the combustor and HP turbine, MTU builds the HP and LP compressors, Avio Aero builds the gearbox and accessories, and ITP Aero builds the LP turbine and reheat nozzle. Each nation operates its own final-assembly line for the engines that power its own Typhoon fleet, an arrangement designed to preserve domestic skills in all four partner countries.

Can the Typhoon really supercruise on EJ200 power alone?

Yes — the Typhoon is one of only two in-service Western fighters that sustains supersonic flight without reheat. At altitude, a clean Typhoon holds around Mach 1.5 on dry thrust; the other is the F-22 Raptor on twin F119 engines. The Rafale on Snecma M88 engines comes close at Mach 1.4 in clean configuration but is generally categorised as transonic-cruise rather than true supercruise.

How many EJ200s have been built?

More than 1,500 had been delivered by 2026 — two per Typhoon across 600-plus aircraft, plus development, attrition reserve, and overhaul rotation engines. Production continues at the four consortium sites in support of the German Quadriga Tranche 4 order, the Italian Tranche 4 buy, the Spanish Halcón I and II batches, and Typhoon export deliveries to Turkey under the 2024 framework agreement.

What is the Phase 4 Enhancement?

Phase 4 Enhancement (P4E) is Eurojet's proposed upgrade to keep the EJ200 competitive into the 2040s. It would lift thrust by around 15%, raise the turbine entry temperature using newer-generation single-crystal blades, integrate the EJ200 TVN thrust-vectoring nozzle, and add prognostic health monitoring. The work is sometimes framed as a technology bridge to the clean-sheet engine being developed by Rolls-Royce, IHI, and Avio for the GCAP sixth-generation fighter.

Has the EJ200 ever powered anything besides the Typhoon?

One ground application: the Bloodhound LSR supersonic land-speed-record car uses an ex-Typhoon flight-test EJ200 to provide air-breathing thrust alongside a hybrid rocket. Bloodhound reached 628 mph during high-speed trials in Hakskeen Pan, South Africa in 2019 before funding pauses delayed the full record attempt. No other aircraft has been fitted with the engine.
