SMS Grosser Kurfürst[a] was the second battleship of the four-ship König class. Grosser Kurfürst (or Großer[b] Kurfürst) served in the German Imperial Navy during World War I. The battleship was laid down in October 1911 and launched on 5 May 1913. She was formally commissioned into the Imperial Navy on 30 July 1914, days before the outbreak of war between Germany and the United Kingdom. Her name means Great Elector, and refers to Frederick William I, the Prince-elector of Brandenburg. Grosser Kurfürst was armed with ten 30.5-centimeter (12.0 in) guns in five twin turrets and could steam at a top speed of 21 knots (39 km/h; 24 mph).
Along with her three sister ships, König, Markgraf, and Kronprinz, Grosser Kurfürst took part in most of the fleet actions during the war, including the Battle of Jutland on 31 May and 1 June 1916. The ship was subjected to heavy fire at Jutland, but was not seriously damaged. She shelled Russian positions during Operation Albion in September and October 1917. Grosser Kurfürst was involved in a number of accidents during her service career; she collided with König and Kronprinz, grounded several times, was torpedoed once, and hit a mine. WIKI
