Fascist Dictators love big warships, to match their inflated genocidal egos. Such vessels are easy prey for determined opponents.

Bismarck was launched in February 1939. Hitler’s Bismarck and her sister ship Tirpitz were the largest battleships ever built by Germany, and two of the largest built by any European power.
Bismarck was eventually attacked by British torpedo bombers. The crippled Bismarck was next engaged by two British battleships and two heavy cruisers, and sustained incapacitating damage and heavy loss of life. The ship was scuttled by the Nazis to prevent her being boarded by the British, and to allow the ship to be abandoned so as to limit further casualties. Most experts agree that the battle damage would have caused her to sink eventually.
