German submarine U-258 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. She was laid down at the Bremer Vulkan yard at Bremen-Vegesack on 22 February 1941 as yard number 23. She was launched on 13 December and commissioned on 4 February 1942.

U-258 was sunk by a Royal Air Force Consolidated B-24 Liberator bomber of 120 Squadron in the North Atlantic on 20 May 1943.

Design[edit]

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-258 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[1] It 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 AEG GU 460/8-276 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged. It had two shafts and two 1.23 m (4 ft) propellers. It was capable of operating at depths of up to 230 metres (750 ft).[1]

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).[1] When submerged, it could operate for 80 nautical miles (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, it could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 10 knots (19 km/h; 12 mph). U-258 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at its bow and one at its stern), fourteen torpedoes, one 8.8 cm (3.46 in) SK C/35 naval gun, 220 rounds, and an anti-aircraft gun. It had a complement of between forty-four and fifty-two.[1]

Wolfpacks[edit]

U-258 took part in eleven wolfpacks, namely.

  • Pfeil (12–22 September 1942)
  • Blitz (22–26 September 1942)
  • Tiger (26–30 September 1942)
  • Wotan (5–17 October 1942)
  • Delphin (23 January – 9 February 1943)
  • Rochen (9–20 February 1943)
  • Adler (11–13 April 1943)
  • Meise (13–27 April 1943)
  • Star (27 April – 4 May 1943)
  • Inn (11–15 May 1943)
  • Donau 1 (15–20 May 1943)
