Kaiser Friedrich III class battleships were a class of pre-World War I German battleship. The class was made up of five ships.
Kaiser Friedrich III was laid down at Wilhelmshaven Navy Dockyard in March, 1895, followed by Kaiser Wilhelm II in October, 1896, also in Wilhelmshaven. Kaiser Wilhelm Der Grosse was laid down at Germania, Kiel in January, 1898, followed by Kaiser Barbarossa at Schichau, Danzig in August of that year, and Kaiser Karl Der Große, a month later in September, at Blohm and Voss, Hamburg.
The Kaiser Friedrich III class saw the introduction of the traditional layout for German battleships prior to the advent of the Dreadnought type of battleship in the early 1900s. The ships saw limited duty during World War I, in V Squadron, until 1915, when the ships were relegated to auxiliary roles, primarily as prison ships. After the war, all five of the ships were sold and scrapped by 1922.
