Two GE LM2500 marine gas turbines now power the HMAS Sydney, 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 Defense, 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.
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).
The LM2500 marine gas turbine is a simple-cycle, two-shaft, high-performance engine. Derived from GE’s CF6-6 aircraft engines, the turbine offers 25 MW of output.
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.
