GE Marine reports that its lightweight LM2500 composite gas turbine module and updated components are now fully certified by the U.S. Navy after receiving MIL-S-901D shock qualification.
Navy approval was obtained after successful shock testing of the composite module and submission of a comprehensive assessment of changes to the LM2500 system.
The U.S. Navy and General Dynamics Bath Iron Works have approved an Engineering Change Proposal for the LM2500 modernized composite module that means that its initial application will be in the future USS Ted Stevens DDG 128, the 78th Arleigh Burke-class destroyer. The ship will feature four GE LM2500 marine gas turbines and will be constructed by Huntington Ingalls Industries.
Austal USA has adapted the weight-saving composite enclosure and will now incorporate this new module on Littoral Combat Ship 32 (the future USS Santa Barbara) and up.
“The Module Modernization Program or MMP was a four-year collaborative effort with the U.S. Navy, Bath Iron Works and GE,” said GE’s Mike Reale, Acting Vice President, General Manager Marine Operations, Evendale, Ohio. “All objectives were met, and in fact, a number were exceeded; the acoustic and thermal performance improvements compared to steel enclosures are striking.”
