MTU developed the MTR390 in cooperation with Safran Helicopter Engines and Rolls-Royce. The turboshaft engine featuring a free power turbine is used to power the Franco-German Tiger support and anti-tank helicopter.

Production engines of the -2C version (basic version) were delivered from 2002 to mid-2010 (of which 242 for the Franco-German Tiger program and 51 for the Australian ARH program). In cooperation with Spain's ITP, MTU developed an enhanced engine version (MTR390-E), which delivers 14 percent more power. The development was completed in 2011. In all, firm orders have been received for 492 MTR390 engines, of which 464 have already been delivered. MTU's share in the Enhanced program comprises the combustion chamber and the high-pressure turbine as well as the engine control and monitoring unit, including the operating system. All production engines are assembled at MTU in Munich.
