Brandenburg-class battleship

The Brandenburg class was a group of four pre-dreadnought battleships built for the German Kaiserliche Marine in the early 1890s: Brandenburg, Wörth, Weissenburg and Kurfürst Friedrich Wilhelm. They were the first modern battleships of the German fleet and the first ocean-going capital ships Germany had built in nearly two decades. Their unusual main battery was six 28 cm guns, at a time when foreign battleships carried four or fewer heavy guns. Power came from two triple-expansion engines fed by twelve coal-fired Scotch boilers. AG Vulcan of Stettin built Brandenburg and Weissenburg, while the other two came from yards at Kiel and Wilhelmshaven, so the class sits partly within the Vulcan output of the 1890s. Two of the ships were later sold to the Ottoman Navy.
