Admiral von Tirpitz secured a series of Naval Laws between 1900 and 1912 that drastically increased the budget of the navy and authorized scores of battleships; the final law envisioned a fleet of some 41 battleships, 25 of which would have been assigned to the High Seas Fleet, with the remainder in reserve.[5] Following the Kaiser Friedrich III class were the Wittelsbach, Braunschweig, and Deutschland classes, the last pre-dreadnoughts built in Germany.[6] The launch of the "all-big-gun" HMS Dreadnought in 1906 revolutionized battleship construction, and forced von Tirpitz to radically alter his shipbuilding plan.[7] In order to remain in the battleship race, Tirpitz secured the funds for the first four German dreadnoughts, the Nassau class, which were laid down beginning in June 1907.[8] The four Helgolands followed in 1908, as well as the five Kaisers in 1909–1910.[9] Four König-class battleships were laid down in 1911–1912, and four Bayern-class battleships were laid down in 1913–1915,[10] though only two—Bayern and Baden—were completed.[11] Germany's defeat in 1918 resulted in the internment of the majority of the High Seas Fleet at Scapa Flow; the ships were eventually scuttled on 21 June 1919 to prevent them from being seized by the British Royal Navy.[12] Of the ten battleships interned, only one, Baden, was prevented from sinking; she was later expended as a gunnery target by the Royal Navy.[11]
