I uploaded a new page for the the Yamato-class battleships 大和型戦艦 that includes the Yamato Battleship and the Musashi Battleship. The information can be found here.
The page includes information about the construction, successive modifications and major operations in which the ship was involved. The images also represents the original ship in those days. I also try to compare the ship characteristics with the counters statistics provided by board-based wargames such as the Empire the Sun.
