Anchors Aweigh For GE Marine

LM2500 gas turbines to power U.S. Navy destroyers; common engine room available to international customers

Posted on October 1, 2013

GE Marine said it will provide eight LM2500 marine gas turbines to power the U.S. Navy’s DDG 117 and DDG 118 destroyers, which will be named the USS Paul Ignatius and the USS Daniel Inouye, respectively.

GE said that through its common engine program, each of the LM2500s will feature improvements including parts upgrade of the compressor rotor, the turbine mid-frame, the compressor rear frame and the power turbine.

Common engine changes are contained within the gas turbine, so as to not impact ship interfaces or on-ship maintenance activities, and this configuration has been recertified to U.S. Navy Mil 901D shock, GE said.

By adopting the LM2500 common engine program, the company said the U.S. Navy can leverage the LM2500 industrial volume to control cost, and improve manufacturing and durability, as well as spare parts lead times.

The eight LM2500 gas turbines – four per ship – will be manufactured at GE’s Evendale, Ohio, U.S.A., facility and will be delivered to shipyards General Dynamics/Bath Iron Works in Bath, Maine, U.S.A., and Huntington Ingalls Industries in Pascagoula, Mississippi, U.S.A., in 2014.
