Germany’s MTU Aero Engines has taken an 18 percent stake in the GE38 turboshaft engine powering the Sikorsky CH-53 Super Stallion heavylift helicopter, marking its first entry into a U.S. military engine program. Under the agreement, MTU, which has previously manufactured components only for U.S. military engines, will have responsibility for the power turbine module. It will also be licensed to maintain, assemble and test the engine and provide MRO services. The deal also provides for engines for the proposed Sikorsky-Eurocopter European heavy transport helicopter. The contract could bring MTU revenues of around $3.2 billion over the life of the GE38.
