When I say best I mean best through it's record and on how the Royal Navy, the greatest Navy ever were so scared by the beast. The Bismarck could go toe-to-toe with any other battleship, it beat the 'greatest' Battleship of the Royal Navy, and took 7 other Battleships plus an aircraft carrier with two Swordfish strikes to bring it down. And even then it was scuttled
Quite an operational record, for it's maiden voyage.
