T408

The T408 is a turboshaft engine that has so far been installed in the U.S. Marine Corps' Sikorsky CH-53K heavy transport helicopter. The so-called "King Stallion" will be equipped with three engines each.

GE Aerospace is producing the engine jointly with MTU. This is the first time the German company has had full responsibility for a complete assembly in a U.S. military engine program. MTU contributes its 18 percent share of the program for the power turbine.
