Supported by Wilhelm II's enthusiasm for an expanded German navy, Grand Admiral Alfred von Tirpitz championed four Fleet Acts from 1898 to 1912, and, from 1902 to 1910, the Royal Navy embarked on its own massive expansion to keep ahead of the Germans. This competition came to focus on the revolutionary new ships based on the Dreadnought, which was launched in 1906, and which gave Britain a battleship that far outclassed any other in Europe.[77][78]
