Australian Warship Now Powered by GE Gas Turbines

Two GE LM2500 marine gas turbines now power the HMAS Sydney (Destroyer – DDG) which was recently commissioned by the Royal Australian Navy (RAN). This is the first commissioning of an Australian warship at sea since the Second World War.

HMAS Sydney is the last of three Hobart class ships built and delivered by the Air Warfare Destroyer (AWD) Alliance which includes the Australian Department of Defence, Raytheon Australia, and ASC Pty Ltd, supported by Navantia Australia. HMAS Sydney’s sister warships are HMAS Hobart and Brisbane, commissioned in 2017 and 2018 respectively; all three ships are homeported at Fleet Base East in Sydney.

Each DDG features two GE LM2500s configured in a Combined Diesel Or Gas turbine (CODOG) arrangement with two diesel engines. The destroyers are based on the design developed by Navantia for the Spanish Navy’s F100 frigate program (Alvaro de Bazan class).

GE LM2500 marine gas turbines also power the Anzac class frigates as well as two Landing Helicopter Dock ships – HMAS Canberra and Adelaide – both the largest ships ever built for the RAN.


GE Marine has been involved in the AWD project for many years supporting the ships’ designer, builder and now the RAN. For instance, for each ship built and delivered, a GE marine gas turbine expert was on board for the first fire of the two LM2500 gas turbines. Another GE team member would take the maiden voyage out of port in Adelaide in support of the builder’s sea trials.

“Now that HMAS Sydney has been commissioned, GE will provide the RAN with long-term, in-service support for the LM2500 gas turbines,” said Kris Shepherd, Vice President and General Manager, GE Marine. “GE ensures the RAN optimum fleet readiness and lower total cost of ownership.”

In addition to the three Hobart class destroyers, GE provides customized shipboard and depot level maintenance for the LM2500 gas turbines on the Anzac and Canberra class ships. The depot level maintenance is performed by Air New Zealand Gas Turbines, an authorized LM2500 service center and longtime RAN service provider.

With a GE gas turbine, navies have worldwide support whether onshore or at sea, and interoperability benefits with other navy and allied ships. The split casing compressor and power turbine design allows for in-situ maintenance, making GE gas turbine removals unnecessary; navies save millions of dollars a year and weeks/months of ship unavailability.
