38 Maritime Reporter & Engineering News recover manned and unmanned surface and sub-surface vehicles up to the size of an 11 m Rigid-Hull Inflatable Boat (RHIB). From its flight deck, X-Craft will be able to operate with two H-60 type helicopters or VTUAVs at a time.
The Sea Fighter's crew will consist of 16 Navy sailors and 10 Coast
Guardsmen.
GE & MTU: Powering the X-Craft
The LM2500 continues to be a suc- cessful performer for the U.S. Navy. GE has delivered over 600 (not including spare engines) LM2500 gas turbines to the U.S. Navy for a variety of combatant programs. The LM2500s power all of the US Navy's surface combatant ships plus AOE supply ships and Sealift ships.
Presently there are more than 2,000
LM2500 gas turbines operating world- wide, logging over 50 million hours in service. GE Transportation, at its
Evendale, Ohio facility, manufactures the LM2500 gas turbines.
GE continues to invest in the LM2500 and its entire LM family of gas turbines, spending more than $473 million over the past decade on research and devel- opment. Improvements include hot sec- tion materials upgrade and other compo- nent enhancements. These improve- ments have increased power capability and reliability, and helped keep the LMs on the cutting edge of gas turbine tech- nology.
GE and MTU have had a productive and successful working relationship dat- ing back to the 1970s. This partnership has made it possible for GE's LM1600,
LM2500 and LM2500+ gas turbines to be used alone or in combination with
MTU diesel engines from their full line of diesel engines. These reliable propul- sion system configurations are available to commercial and military marine cus-
