Germany Battleship
In 1938 and 1939, a plan for the modernization and expansion of the German fleet was developed. Six new battleships were supposed to become the core of the fleet—modernized versions of the Bismarck-class battleships with a diesel power plant and increased gun caliber of up to 406 mm. In July 1939, the keel of the first ship was laid down at the Blohm & Voss shipyard in Hamburg, and in September, the construction of the second one began in Bremen. With the outbreak of World War II, construction was suspended and then canceled.
