German submarine U-905 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.
She was ordered on 6 August 1942, and was laid down on 26 January 1943 at H. C. Stülcken Sohn, Hamburg, as yard number 802. She was launched on 20 November 1943 and commissioned under the command of Oberleutnant zur See Heinz-Ehler Brüllau on 8 March 1944.[3]
Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-905 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged. She had a total length of 67.10 m (220 ft 2 in), a pressure hull length of 50.50 m (165 ft 8 in), a beam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two SSW GU 343/38-8 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged. She had two shafts and two 1.23 m (4 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).
The submarine had a maximum surface speed of 17.7 knots (32.8 km/h; 20.4 mph) and a maximum submerged speed of 7.6 knots (14.1 km/h; 8.7 mph). When submerged, the boat could operate for 80 nautical miles (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 10 knots (19 km/h; 12 mph). U-905 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes or 26 TMA mines, one 8.8 cm (3.46 in) SK C/35 naval gun, (220 rounds), one 3.7 cm (1.5 in) Flak M42 and two twin 2 cm (0.79 in) C/30 anti-aircraft guns. The boat had a complement of between 44 — 52 men.
Service history
On 27 March 1945, U-905 was sunk by depth charges in the North Minch in the North Atlantic, by the British frigate HMS Conn. Oberleutnant zur See Bernhard Schwarting and 44 other crewmen were all lost.[3]
The wreck is located at 58°34′N 05°46′W / 58.567°N 5.767°W / 58.567; -5.767.[3]
