FH1117

Bismarck was the first of two Bismarck-class battleships built for Nazi Germany’s Kriegsmarine. Named after Chancellor Otto von Bismarck, the ship was laid down at the Blohm & Voss shipyard in Hamburg in July 1936 and launched in February 1939. Work was completed in August 1940, when she was commissioned into the German fleet. Bismarck and her sister ship Tirpitz were the largest battleships ever built by Germany, and two of the largest built by any European power.

In the course of the warship’s eight-month career under its sole commanding officer, Captain Ernst Lindemann, Bismarckconducted only one offensive operation, in May 1941, codenamed Rheinübung. The ship, along with the heavy cruiser Prinz Eugen, was to break into the Atlantic Ocean and raid Allied shipping from North America to Great Britain. The two ships were detected several times off Scandinavia, and British naval units were deployed to block their route. At the Battle of the Denmark Strait, the iconic battlecruiser HMS Hood initially engaged Prinz Eugen, probably by mistake, while HMS Prince of Wales engaged Bismarck. In the ensuing battle Hood was destroyed by the combined fire of Bismarck and Prinz Eugen, who then damaged Prince of Wales and forced her retreat. Bismarck suffered sufficient damage from three hits to force an end to the raiding mission.

The destruction of Hood spurred a relentless pursuit by the Royal Navy involving dozens of warships. Two days later, heading for occupied France to effect repairs, Bismarck was attacked by 16 obsolescent Fairey Swordfish biplane torpedo bombers from the aircraft carrier HMS Ark Royal; one scored a hit that rendered the battleship’s steering gear inoperable. In her final battle the following morning, the already-crippled Bismarck was severely damaged during a sustained engagement with two British battleships and two heavy cruisers, was scuttled by her crew, and sank with heavy loss of life. Most experts agree that the battle damage would have caused her to sink eventually. The wreck was located in June 1989 by Robert Ballard, and has since been further surveyed by several other expeditions.

Construction and characteristics

Bismarck was ordered under the name Ersatz Hannover (“Hannover replacement”), a replacement for the old pre-dreadnoughtSMS Hannover, under contract “F”. The contract was awarded to the Blohm & Voss shipyard in Hamburg, where the keel was laid on 1 July 1936 at Helgen IX. The ship was launched on 14 February 1939 and during the elaborate ceremonies was christened by Dorothee von Löwenfeld, granddaughter of Chancellor Otto von Bismarck, the ship’s namesake. Adolf Hitler made the christening speech. Fitting-out work followed the launch, during which time the original straight stem was replaced with a raked “Atlantic bow” similar to those of the Scharnhorst-class battleships. Bismarck was commissioned into the fleet on 24 August 1940 for sea trials, which were conducted in the Baltic. Kapitän zur See Ernst Lindemann took command of the ship at the time of commissioning.

Bismarck displaced 41,700 t (41,000 long tons) as built and 50,300 t (49,500 long tons) fully loaded, with an overall length of 251 m (823 ft 6 in), a beam of 36 m (118 ft 1 in) and a maximum draft of 9.9 m (32 ft 6 in). The battleship was Germany’s largest warship, and displaced more than any other European battleship, with the exception of HMS Vanguard, commissioned after the end of the war.Bismarck was powered by three Blohm & Voss geared steam turbines and twelve oil-fired Wagner superheatedboilers, which developed a total of 148,116 shp (110,450 kW) and yielded a maximum speed of 30.01 knots (55.58 km/h; 34.53 mph) on speed trials. The ship had a cruising range of 8,870 nautical miles (16,430 km; 10,210 mi) at 19 knots (35 km/h; 22 mph).Bismarck was equipped with three FuMO 23 search radar sets, mounted on the forward and stern rangefinders and foretop.

The standard crew numbered 103 officers and 1,962 enlisted men. The crew was divided into twelve divisions of between 180 and 220 men. The first six divisions were assigned to the ship’s armament, divisions one to four for the main and secondary batteries and five and six manning anti-aircraft guns. The seventh division consisted of specialists, including cooks and carpenters, and the eighth division consisted of ammunition handlers. The radio operators, signalmen, and quartermasters were assigned to the ninth division. The last three divisions were the engine room personnel. When Bismarck left port, fleet staff, prize crews, and war correspondents increased the crew complement to over 2,200 men.Roughly 200 of the engine room personnel came from the light cruiser Karlsruhe, which had been lost during Operation Weserübung, the German invasion of Norway. Bismarck‘s crew published a ship’s newspaper titled Die Schiffsglocke (The Ship’s Bell); this paper was only published once, on 23 April 1941, by the commander of the engineering department, Gerhard Junack.

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”. 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. Bismarck also carried four Arado Ar 196 reconnaissance floatplanes, with a single large hangar and a double-ended catapult. 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.
