The Battleship Bismarck is available in the WW2 age to the Modern age. During those times it is one of the most powerful ships at sea, sinking every other ship. But, they are countered by Submarines and Planes (Bomber and Bomber/Fighter). To avoid being sunk, it should have a Frigate or Cruiser by its side or, a Sub to help counter other subs or other Battleships. That are very vulnerable and very strong. Its guns cannot attack subs so it is very vulnerable to them, but can still attack Hyperion which are underwater.
