A series of conceptual designs was begun in 1932 to determine the ideal characteristics of a battleship built to the 35,000 long tons (36,000 t) limit of the Washington Naval Treaty. These early studies determined that the ship should be armed with eight 33 cm (13 in) guns, have a top speed of 30 knots (56 km/h; 35 mph), and have strong armor protection. The design work for what became the Bismarck class was begun in 1933 and continued until 1936. A series of questions needed to be answered during the design process, including the caliber of the main battery, the propulsion system, and armor protection. The deciding factor for the adoption of 38 cm (15 in) guns for Bismarck and Tirpitz was the decision of the French Navy to arm its four Richelieu-class ships then under construction with 38 cm pieces. It was decided that four twin turrets would provide the best solution to distribution of the main battery, as it would provide equal firepower forward and aft, as well as simplify fire control. This arrangement was similar to the last German battleships of the Imperial period, the Bayern class. The similarity led to speculation that the Bismarcks were essentially copies of the earlier ships, though the arrangement of the main battery was the only shared trait, along with a three-shaft propulsion system. The battleship was Germany's largest warship,[8] and displaced more than any other European battleship, with the exception of HMS Vanguard, commissioned after the end of the war.[9] Bismarck was powered by three Blohm & Voss geared steam turbines and twelve oil-fired Wagner superheated boilers, which developed a total of 148,116 shp (110,450 kW) and yielded a maximum speed of 30.01 knots On 15 September 1940, three weeks after commissioning, Bismarck left Hamburg to begin sea trials in Kiel Bay.[16] Sperrbrecher 13 escorted the ship to Arcona on 28 September, and then on to Gotenhafen for trials in the Gulf of Danzig. The ship's power-plant was given a thorough workout; Bismarck made measured-mile and high speed runs. As the ship's stability and manoeuvrability were being tested, a flaw in her design was discovered. When attempting to steer the ship solely through altering propeller revolutions, the crew learned that Bismarck could be kept on course only with great difficulty. Even with the outboard screws running at full power in opposite directions, they generated only a slight turning ability. Bismarck's main battery guns were first test-fired in late November. The tests proved she was a very stable gun platform.Bismarck was armed with eight 38 cm (15 in) SK C/34 guns arranged in four twin gun turrets: two super-firing turrets forward—"Anton" and "Bruno"—and two aft—"Caesar" and "Dora".[c] Secondary armament consisted of twelve 15 cm (5.9 in) L/55 guns, sixteen 10.5 cm (4.1 in) L/65 and sixteen 3.7 cm (1.5 in) L/83, and twelve 2 cm (0.79 in) anti-aircraft guns. The ship's main belt was 320 mm (12.6 in) thick and was covered by a pair of upper and main armoured decks that were 50 mm (2.0 in) and 100 to 120 mm (3.9 to 4.7 in) thick, respectively. The 38 cm (15 in) turrets were protected by 360 mm (14.2 in) thick faces and 220 mm (8.7 in) thick sides. WWII Armada notes:Bismark has been given outstanding defensive capability in Engineering and Defense tokens to represent her toughness in battle with an offsetting lack of firepower and maneuverability as compared to other BB's of this era.
