German submarine U-83 was a Type VIIB U-boat of Nazi Germany's Kriegsmarine during World War II.

She was laid down in the Flender Werke at Lubeck as yard number 291 on 5 October 1939. Launched on 9 December 1940, she was commissioned on 8 February 1941. U-83 served with 1st U-boat Flotilla from 8 February 1941 to 31 December, with the 23rd flotilla from 1 January 1942 to 30 April and with the 29th flotilla from 1 March 1942 until she was sunk.[2]

Design[edit]

German Type VIIB submarines were preceded by the shorter Type VIIA submarines. U-83 had a displacement of 753 tonnes (741 long tons) when at the surface and 857 tonnes (843 long tons) while submerged.[4] She had a total length of 66.50 m (218 ft 2 in), a pressure hull length of 48.80 m (160 ft 1 in), a beam of 6.20 m (20 ft 4 in), a height of 9.50 m (31 ft 2 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 AEG GU 460/8-276 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).[4]

The submarine had a maximum surface speed of 17.9 knots (33.2 km/h; 20.6 mph) and a maximum submerged speed of 8 knots (15 km/h; 9.2 mph).[4] When submerged, the boat could operate for 90 nautical miles (170 km; 100 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 8,700 nautical miles (16,100 km; 10,000 mi) at 10 knots (19 km/h; 12 mph). U-83 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm (3.46 in) SK C/35 naval gun, 220 rounds, and one 2 cm (0.79 in) anti-aircraft gun The boat had a complement of between forty-four and sixty.[4]

Service history[edit]

U-83 conducted twelve patrols and sank five ships totalling 8,194 gross register tons (GRT) and one auxiliary warship - the Q-ship HMS Farouk, of 91 GRT.[5] She damaged one other ship of 2,590 GRT and damaged the fighter catapult ship HMS Ariguani, of 6,746 GRT.[2][6]

U-83 was sunk on 4 March 1943 with all hands southeast of Cartagena in Spain in position 37°10′N 00°05′E / 37.167°N 0.083°E / 37.167; 0.083Coordinates: 37°10′N 00°05′E / 37.167°N 0.083°E / 37.167; 0.083, by three depth charges dropped from an RAF Hudson bomber (500 Squadron).[2][1]

Wolfpacks[edit]

U-83 took part in three wolfpacks, namely.

  • Bosemüller (28 August - 2 September 1941)
  • Seewolf (2–7 September 1941)
  • Breslau (2–29 October 1941)
