The Imperial German Navy was slow to adopt the advanced Parsons turbine engines used in the British "Dreadnought", primarily due to the resistance of both Tirpitz and the Navy's construction department. In 1905, the latter stated that the "use of turbines in heavy warships does not recommend itself." This decision was based solely on cost: at the time, Parsons held a monopoly on steam turbines and required a 1 million mark royalty fee for every turbine engine made. German firms were not ready to begin production of turbines on a large scale until 1910.
