GE’s LM2500 to power new DDG destroyers

23rd March 2018 - 12:30 GMT | by The Shephard News Team


GE’s Marine Solutions’ LM2500 marine gas turbines have been selected to power the US Navy's DDG 126 and 127 Arleigh Burke-class destroyers, the company announced on 19 March.

The destroyers are being built by General Dynamics Bath Iron Works.

The LM2500 marine gas turbine is a simple-cycle, two-shaft, high-performance engine. It consists of a gas generator, a power turbine, attached fuel and lube oil pumps, a fuel control and speed governing system, associated inlet and exhaust sections, lube and scavenge systems and controls and devices for starting and monitoring engine operation.

GE’s engineering team has collaborated with Bath Iron Works on the LM2500 module modernisation programme. Under the programme, GE has designed a composite enclosure that has a 50% reduction in wall weight and several crew safety features. Introduction of the lightweight composite enclosure is expected in the coming 12 months.

Brien Bolsinger, VP, marine operations, GE, said: ‘Each of these sophisticated new surface combatants relies on four powerful GE LM2500 marine gas turbines in a combined gas and gas turbine – or COGAG – propulsion arrangement. We are honoured that this reliable gas turbine assists with our country’s national security. The US Navy is the largest customer of GE marine gas turbines that are proudly manufactured right here in Ohio.’
