    V12 marine diesel engines . Human-powered paddles and oars, and later, sails were the first forms of marine propulsion. Rowed galleys, some equipped with sail, played an important early role in early human seafaring and warfares. The first advanced mechanical means of marine propulsion was the marine steam engine, introduced in the early 19th ...

    The Rolls-Royce MT30 (Marine Turbine) is a marine gas turbine engine based on the Rolls-Royce Trent 800 aero engine. The MT30 retains 80% commonality with the Trent 800, the engine for the Boeing 777. The maximum power rating is 40 MW and minimum efficient power 25 MW. [1] Rolls-Royce announced the MT30 program on 11 September 2001.

    Kockums also delivered Stirling engines to Japan. Ten Japanese submarines were equipped with Stirling engines. The first submarine in the class, Sōryū, was launched on 5 December 2007 and delivered to the navy in March 2009. The eleventh of the class is the first one that is equipped with lithium-ion batteries without a Stirling engine. [16]
