GE to Provide LM2500 Marine Gas Turbines to Power New U.S. Navy Destroyers

EVENDALE, OHIO — GE Marine Solutions’ LM2500 marine gas turbines have been selected to power the U.S. Navy’s new DDG 126 and 127 Arleigh Burke-class guided-missile destroyers, the company announced in a March 19 release. The destroyers are being built by General Dynamics Bath Iron Works, Bath, Maine.

“Each of these sophisticated new surface combatants relies on four powerful GE LM2500 marine gas turbines in a combined gas and gas turbine — or COGAG — propulsion arrangement,” said GE’s Brien Bolsinger, vice president, Marine Operations. “We are honored that this reliable gas turbine assists with our country’s national security. The U.S. Navy is the largest customer of GE marine gas turbines that are proudly manufactured right here in Ohio.”

GE’s engineering team also collaborates with Bath Iron Works on the LM2500 module modernization program. Through this initiative, GE designed a composite enclosure that has a 50-percent reduction in wall weight and several crew safety features. Introduction of this lightweight composite enclosure is anticipated in the next year.

GE already has delivered more than 750 gas turbines to the U.S. Navy to power frigates, destroyers, cruisers and amphibious ships. In addition, the company has nine depot service centers worldwide that provide full overhaul capability for the LM2500, avoiding the need to send gas turbines overseas for shop maintenance. Thus, GE is well positioned to support the world’s naval propulsion needs via its six propulsion gas turbines that range in power from 4.5 to 52 megawatts. This flexibility enables architects to design ships according to specific mission profiles and cost objectives.

Fleet commonality of a single gas turbine also affords the U.S. Navy a support pool of standardized spare parts, a common gas turbine infrastructure and training program for these fleets, and the flexibility to move propulsion crews across ship platforms with no incremental training.

The LM2500 has logged more than 15 million hours in marine applications as well as another 70 plus million hours in industrial applications. These gas turbines operate for the U.S. Navy and 34 other navies the world over in some of the most arduous conditions.
