The MTR390 covers the 1,250 to 1,450 shp range. It is designed for six-to-seven ton military rotorcraft and is installed in the Airbus Helicopters Tiger attack helicopter. The development of the MTR390 is the result of a partnership between MTU Aero Engines, Rolls-Royce, ITP and Safran Helicopter Engines. Production began in 2000. Two versions are in service: the 2C fitted to the Tiger HAP, ARH and UHT variants; and the E, intended for the Tiger HAD. The in-service fleet has collectively logged over 130,000 operating hours.

With unrivaled power-to-weight and dimensions-to-power ratios, the MTR390 is designed for performance. The E model offers a maximum take-off power of 1,467 shp and, using the One Engine Inoperative (OEI) rating, is capable of 1,773 shp.

The MTR390 was designed to perform in the harshest of environments and to offer simple maintenance. It features three main modules: a compressor with two centrifugal stages (to cope with the most difficult conditions, including sandy environments); a single-stage high pressure turbine equipped with cooled single-crystal vanes; and a particularly robust two-stage power turbine. Servicing is based on the concept of on-condition maintenance and requires a simple set of standard tools.

The MTR390 is equipped with dual-channel Full Authority Digital Engine Control (FADEC) which, through allowing engine performance and usage monitoring, lightens air and ground crew workload while maximizing performance.

The MTR390 is in service in France, Germany, Spain and Australia. As a result of the Tiger's operational commitments, the MTR390 has flown combat missions in Afghanistan, Libya and Mali.

MTR390 2C

The MTR390 2C is intended for the HAP, ARH and UHT Tigers ordered by France, Germany, Spain and Australia.


Certified in 2011, the 2C is capable of a take-off power of 1,285 shp, and a cruising power of 1,171 shp. Maximum power via the One Engine Inoperative (OEI) rating is 1,556 shp.
