SMS Kaiser was the lead ship of the Kaiser class of dreadnought battleships of the Imperial German Navy. Kaiser was built by the Imperial Dockyard at Kiel, launched on 22 March 1911 and commissioned on 1 August 1912. The ship was equipped with ten 30.5-centimeter (12 in) guns in five twin turrets, and
had a top speed of 23.4 knots (43.3 km/h; 26.9 mph). Kaiser was assigned to III Battle Squadron of the High Seas Fleet for the majority of World War I.



In 1913, Kaiser and her sister König Albert conducted a cruise to South America and South Africa. The ship participated in most of the major fleet operations during the war. She fought at the Battle of Jutland on 31 May – 1 June 1916, during which she was hit twice and suffered negligible damage. The ship was also present during Operation Albion in the Baltic Sea in September and October 1917, and at the Second Battle of Heligoland Bight in November 1917.



During peace negotiations after the end of the war in 1918, she was interned with other ships of the High Seas Fleet at Scapa Flow. On 21 June 1919 the commander of the interned fleet, Rear Admiral Ludwig von Reuter, ordered the fleet to be scuttled to ensure that the British would not be able to seize the ships. The wreck was raised in 1929 and broken up in Rosyth in 1930.
