The General Electric (GE) Marine Solutions LM2500 is the primary gas turbine of the Navy surface fleet. More than 700 of the engines are on board Ticonderoga-class cruisers, Arleigh Burke–class destroyers (DDGs), the USS Makin Island (LHD-8), the America (LHA-6), and the Coast Guard’s Legend-class national security cutters, among others. George Awiszus, GE’s director of military marketing, notes that the company now provides 97 percent of the Navy’s gas turbine engines.
The Independence-class littoral combat ships (LCSs) also use the LM2500, with Austal USA delivering seven ships to date. (The Freedom-class LCSs, built by Fincantieri Marinette Marine, are powered by Rolls Royce MT30 gas turbines.) The family of engines includes the base LM2500, rated at 25 megawatts; LM2500+ (30 MW); and LM2500+G4 (35 MW).
