This steam reached very high pressure and was then delivered to the turbines that turned the propellers. The ship suffered more serious damage from manoeuvres to evade the torpedoes: rapid shifts in speed and course loosened collision mats, which increased the flooding from the forward shell hole and eventually forced abandonment of the port number 2 boiler room. The high pressure steam was made by twelve Wagner Hochdruck high pressure steam-heated boilers, turning three Blohm & Voss turbine. The heavy 16-inch (40.6cm) guns turn most enemies at medium range into ‘firewood’, especially with ships up to the same Tier VI, but they are still effective in battles in higher areas, such as Tier VII and VIII. For the last few minutes of the turn to port, Bismarck was out of range of Suffolk's radar. This manoeuvre coincided with the period during which his ship was out of radar range; Bismarck successfully broke radar contact and circled back behind her pursuers. Dorsetshire then moved around to her port side and fired another torpedo, which also hit.  One torpedo hit amidships on the port side, just below the bottom edge of the main armour belt. Another battleship, King George V or Renown, turned away damaged.  Bismarck led Prinz Eugen by about 700 m (770 yd); mist reduced visibility to 3,000–4,000 m (3,300–4,400 yd). Four U-boats would be placed along the convoy routes between Halifax and Britain to scout for the raiders. The force of the explosion was largely contained by the underwater protection system and the belt armour but some structural damage caused minor flooding. , Shortly after the Swordfish departed from the scene, Bismarck and Prince of Wales engaged in a brief artillery duel. , Ballard's survey found no underwater penetrations of the ship's fully armoured citadel.  The forecastle hit allowed 1,000 to 2,000 t (980 to 1,970 long tons) of water to flood into the ship, which contaminated fuel oil stored in the bow. Shell fragments rained down on Sheffield, killing three men and wounding several others. Shell-splinters from the second hit also damaged a steam line in the turbo-generator room, but this was not serious, as Bismarck had sufficient other generator reserves. As the ship's stability and manoeuvrability were being tested, a flaw in her design was discovered. The sea water that had flooded the number 2 port side boiler threatened to enter the number 4 turbo-generator feedwater system, which would have permitted saltwater to reach the turbines. The harsh weather broke on the morning of 24 May, revealing a clear sky. , The Royal Navy search became frantic, as many of the British ships were low on fuel. The last three divisions were the engine room personnel. Even a Battleship Bismarck on Tier VIII could be defeated and sunk by the author ! Though fuel shortages had reduced the number of ships available to the British, the battleships King George V and Rodney were still available, along with the heavy cruisers Dorsetshire and Norfolk.  None of the attacking aircraft were shot down. Bismarck was laid down at the Blohm & Voss shipyard on 1 July 1936. William N. Lange, a Woods Hole expert, stated, "You see a large number of shell holes in the superstructure and deck, but not that many along the side, and none below the waterline.  The contract was awarded to the Blohm & Voss shipyard in Hamburg, where the keel was laid on 1 July 1936 at Helgen IX. Technical data and specifications of the German battleship Bismarck. Tovey could now turn his forces toward France to converge in areas through which Bismarck would have to pass. At approximately the same time, a group of ten or twelve Swedish aircraft flying reconnaissance encountered the German force and reported its composition and heading, though the Germans did not see the Swedes. Force H, with the aircraft carrier Ark Royal and steaming up from Gibraltar, was still at least a day away. 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. Two days later, heading for occupied France to effect repairs, Bismarck was attacked by 16 Fairey Swordfish biplane torpedo bombers from the aircraft carrier HMS Ark Royal; one scored a hit that rendered the battleship's steering gear inoperable. Out of a crew of over 2,200 men, only 114 survived. She was joined at 11:25 by Prinz Eugen, which had departed the previous night at 21:18, off Cape Arkona. The "H-41" design improved the "H-39" ship with still larger main guns, eight 42 cm (16.5 in) weapons, and reinforced deck armor. Divers repaired the collision mats in the bow, after which speed increased to 20 knots (37 km/h; 23 mph), the speed that the command staff determined was the most economical for the voyage to occupied France.  Oels rushed throughout the ship, ordering men to abandon their posts.  Thereafter, Bismarck's ability to aim her guns deteriorated as the ship, unable to steer, moved erratically in the heavy seas and deprived Schneider of a predictable course for range calculations.  Upon receipt of the information, Admiral John Tovey ordered the battlecruiser HMS Hood, the newly commissioned battleship HMS Prince of Wales, and six destroyers to reinforce the pair of cruisers patrolling the Denmark Strait.  Some survivors reported they saw Captain Lindemann standing at attention at the stem of the ship as she sank. We will fight to the last shell.  Overall the four British ships fired more than 2,800 shells at Bismarck, and scored more than 400 hits, but were unable to sink Bismarck by gunfire. The signals were intercepted by the British, from which bearings were determined. The British were unaware that the German ships had reversed positions in the Denmark Strait. 1 on the starboard side, was the Diesel motor room No.
