During the duration of the Second World War, the German Kriegsmarine (Navy) introduced four new types of battleship that posed a massive threat to the Allied equivalents patrolling the shipping lanes in the Pacific and Atlantic oceans. The design and construction of the famous Bismarck and Tirpitz battleships saw two of the most advanced and revered ships in the history of naval warfare. These giants of the naval world displaced over 50,000 tons and had an arsenal containing over 70 large cannons, including eight 38 cm guns. The launching of these two iconic ships in Hamburg and Wilhelmshaven went down in the history books as a highlight of naval history. This DVD shows these maritime heavyweights in action, from their launch and basic training to operations in the open ocean.
