GE Marine Gas Turbines Selected for Newbuild Surface Combatants
EVENDALE, Ohio — GE’s Marine Solutions’ LM2500 family of aeroderivative marine gas turbines have been selected to power two new-build surface combatants for U.S. Navy and Coast Guard programs, the company announced in an Aug. 30 release.
Specifically, two LM2500+ gas turbines will power Bougainville (LHA 8), the Navy’s newest multi-purpose amphibious assault ship. Construction is expected to begin shortly, according to shipbuilder Huntington Ingalls Industries. GE LM2500+ gas turbines also power the first-in-class USS America (LHA 6) and Tripoli (LHA 7). Tripoli is under construction and was launched on May 1; it will be christened on Sept. 16.
The LHA ships use the same LM2500+ gas turbine hybrid electric propulsion system as the Navy’s USS Makin Island (LHD 8) amphibious assault ship. Thanks to this unique propulsion system, the Navy expects to see fuel savings of more than $250 million over the course of the ship’s life cycle.
Separately, a GE LM2500 engine in a combined diesel and gas turbine propulsion system will power the Coast Guard’s ninth National Security Cutter (NSC). All ships in the NSC Legend class feature the same LM2500 gas turbine system. Kimball (NSC 7) was launched by Huntington Ingalls Industries in Pascagoula, Miss., on March 4. The keel for sister ship Midgett (NSC 8) was authenticated on Jan. 27.
GE marine gas turbines can be applied in a variety of propulsion configurations so naval architects have the design flexibility to best match speed, endurance and mission payload requirements. The LM2500 family of marine gas turbines is manufactured at GE’s Evendale factory.
