Powering U.S. Navy’s Surface Combatants

GE to supply LM2500 turbines for Littoral Combat Ships

Posted on May 2, 2013

GE Marine announced it will provide Mobile, Alabama, U.S.A.-based Austal USA with four LM2500 marine aeroderivative gas turbines to power the United States Navy’s 14th and 16th Independence-variant Littoral Combat Ships (LCS).

The Austal-built LCSs are powered by two LM2500s arranged in a combined diesel or gas turbine configuration with two diesel engines.

The 127 m aluminum trimaran LCS is an agile surface combatant that can be deployed independently to overseas littoral regions – the part of a sea, lake or river that is close to the shore. The LCS 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.

According to Austal, the Coronado (LCS 4) will complete sea trials later this spring. Construction of two additional LCSs is currently underway in Austal’s Mobile shipyard.

In total, GE is providing 20 LM2500 gas turbines for the Austal LCS program, part of a contract for up to 10 ships over a five-year period. All the LM2500 gas turbines for the Austal LCS program were or will be manufactured at GE’s Evendale, Ohio, U.S.A. facility.
