Carrying the largest, most destructive naval guns ever built and protected by massive steel armour, battleships were designed to be the ultimate expression of naval power. They were the embodiment of the cherished belief held by virtually every naval commander since the age of sail that the immense might of naval gunfire was the decisive element in combat at sea. Now you can relive the power of these ships, from the dreadnoughts of the First World War to the last use of a battleship in the Gulf War. See the greatest naval battles of the 20th century - Jutland, the Bismarck chase and Leyte Gulf - and experience the might of a battle fleet in action.
