GE LM2500 Gas Turbines Power Newly-Christened Coronado Austal Trimaran Littoral Combat Ship

GE Marine announces its LM2500 aeroderivative gas turbines now power the United States Navy’s Coronado, trimaran Littoral Combat Ship. Coronado  — the second Austal USA-built LCS — was recently christened at Austal USA’s Mobile, Ala., shipyard.

The Coronadois powered by two LM2500s arranged in a CODAG configuration with two diesel engines. Cincinnati-based GE Marine says it will provide Austal USA with eight LM2500 gas turbines for the Independence-variant LCS program, part of a contract for up to 10 ships over a five-year period. This past summer, Austal USA celebrated the cutting of metal on Jackson, the third Austal LCS, also powered by two LM2500s in a CODAG arrangement.

The 127-meter aluminum trimaran LCS is an agile surface combatant that can be deployed independently to overseas littoral regions, can remain on station for an extended period either with a battle group or through a forward-basing arrangement, and is capable of underway replenishment.

All the LM2500 gas turbines for the Austal LCS program were or will be manufactured at GE’s Evendale, Ohio, facility.
