World War 2 Sink of the Bismark
The German battleship Bismarck is one of the most famous warships of the Second World War. Named after the 19th century German chancellor Otto von Bismarck, Bismarck's fame came from the Battle of the Denmark Strait in May 1941 (in which the battlecruiser HMS Hood, flagship and pride of the British Royal Navy, was sunk), from Churchill's subsequent order to "Sink the Bismarck" , and from the relentless pursuit by the Royal Navy that ended with her loss only three days later.

History
Design of the ship started in the early 1930s, following on from Germany's development of the pocket battleshipDeutschland class cruisers and theGneisenau class "battlecruisers". Construction of the second FrenchDunkerque class battleship made redesign necessary, and Bismarck'sdisplacement was increased to 42,600 tons, although officially her tonnage was still only 35,000 tons to suggest parity with ships built within the limits of the Treaty of Versailles. Fully laden,Bismarck and her sister-ship Tirpitzwould each displace more than 50,000 tons. The prototype of the proposed battleships envisaged under Plan Z, Bismarck's keel was laid down at the Blohm + Voss shipyard in Hamburg on 1 July 1936. She was launched on 14 February 1939 and commissioned on 24 August 1940 with Kapitän zur See Ernst Lindemann in command.
This formidable ship was intended primarily as a commerce raider, having a broad beam for stability in the rough seas of the North Atlantic and fuel stores as large as those of battleships intended for operations in the Pacific Ocean. Still, with eight 15 inch main guns in four turrets, substantial welded-armour protection and designed for a top speed of not less than 29 knots (she actually achieved 30.1 knots in trials in the calmer waters of the Baltic, an impressive speed when set against any comparable British battleship), Bismarck was capable of engaging any enemy battleship on reasonably equal terms. Her range of weaponry could easily decimate any convoy she encountered. The plan was for Bismarck to break through into the spacious waters of the North Atlantic, where she could refuel from German tankers and (the Germans hoped) remain undetected by British and American aircraft, submarines and ships, while attacking the convoys.
