Bismarck is (to date) the only ship-girl in Kancolle's roster with a third remodel which serves more of an actual upgrade rather than a ship class change (like the Chitose-class). Her [i]drei[/i] form gives her the ability to launch torpedoes. This refers to Tirpitz's own modifications which included the addition of torpedo launchers. She never got those modifications, having been sunk in early 1941.
