The Bismarck class battle cruisers were a type of United Federation of Planets starship on active duty in Starfleet during at least the late 23rd century. (Task Force Games: UFP: The Federation Sourcebook for Prime Directive) The Bismarck class was produced concurrently with the Kirov-class battle cruisers. The Bismarcks used borrowed Gorn technology (plasma-F launchers) in place of the drone racks on the Kirovs. The standard crew complement of a Bismarck was 401 (including a Prime Team) plus 102 surface action specialists.
