GE Marine reports that its LM2500 gas turbines will be used to power the U.S. Navy's next Littoral Combat Ship (LCS 4). GE will supply the two LM2500 gas turbine modules to Austal USA, Mobile, Alabama.

As the sea frame designer and builder, Austal USA is a subcontractor to Bath Iron Works, Bath, Maine, a General Dynamics company and the prime contractor for the General Dynamics LCS program.

The Independence (LCS 2) -- also built by Austal USA/Bath Iron Works --also features two GE LM2500 gas turbines. The keel for this vessel was laid on January 19, 2006."

In the General Dynamics trimaran LCS, the two LM2500 gas turbines and two diesel engines configured into a combined diesel and gas turbine arrangement, with four steerable waterjets and one steerable thruster.

The LM2500 gas turbines will each be rated at 29,500 shaft horsepower at U.S. Navy standard day conditions (100oF). The gas turbines will be manufactured at GE's Evendale, Ohio facility, and will be delivered to Austal USA in September 2007.
