The Rolls-Royce MT30 gas turbine chosen for the Republic of Korea Navy’s FFXII frigate last year, and already installed with the US Navy and UK Royal Navy, is the world’s most powerful marine gas turbine.  It owes this impressive tag to the Rolls-Royce aero engine from which it is derived – the Boeing 777’s Trent 800 power plant, which has the largest core of the company’s renowned Trent engine family.
