      • You're not comparing like for like. marine gas turbines don't have the front fan that an aircraft turbine has; all it needs and has is the core. It's 2/3rds of an aero engine, really.

        • The success of the Illustrious type carrier was the option to swap engines with other ships in service, i.e Type 42. Otherwise, when engine overhaul or repairs are required, a frequent occurrence on Gas Turbines, the engine comes out and the ship is tied up, dead in the water.
          Vince, Lusty and Ark all carried spare turbines, which were rotated between ships at frequent intervals.

          • Rolls Royce Olympus was the choice of high performance gas turbine for the RN for 40 year...also used by Concorde. If its one thing the RN get spot on everything its engines....apart from the Mirlees in the Ton Class sweepers.

              so 2 MT30s. are 2/3 of the of an engine each which supply 2/3 of the 109MW needed for the ship. What supplies the other 1/3 of the power required

                Oars. Lots of Oars - manned by the marines on board to keep em fit. Current economic climate and all that.

                    • On February 7, 2013, the massive 'forward island' of HMS Queen Elizabeth began her journey from Portsmouth where she was constructed, to Rosyth where the aircraft carrier is under assembly.

                      • @apc, the marine version will obviously develop enough power in it's own right, but purely from a core-minus-fan. Yes, it has the normal compressor at the front but no fan, which is the very wide front stage of the engine. Next time you go to the airport, have a look at the fan at the front of the jet engines. That's missing from marine engines because they don't need it. they most likely have an extra stage of compressor to make up the difference. here endeth the lesson.
