GE38

The GE38 is a turboshaft engine targeted at various helicopter and turboprop applications, such as the CH-53K heavy-lift helicopter for the U.S. Marine Corps. Other potential applications include the Future Transport Helicopter for European armed forces, transport aircraft, marine propulsion and power generation systems.

The engine is produced jointly by General Electric Aviation (GE) and MTU. In a first for the company, MTU also has a development role for a module under a U.S. military engine program. The company is responsible for the development and manufacture of the power turbine and will obtain licenses for maintenance, final assembly and testing of the GE38 models to power a future European heavy-lift helicopter (FTH = Future Transport Helicopter). The German engine maker has a program stake of 18 percent.
