German submarine U-741 was a Type VIIC U-boat built by F Schichau GmbH of Danzig and commissioned on 10 April 1943.[1]

Design[edit]

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-741 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[2] 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 AEG GU 460/8–27 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).[2]

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).[2] 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-741 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 an anti-aircraft gun. The boat had a complement of between forty-four and sixty.[2]

Service history[edit]

On 15 August 1944, she attacked convoy FTM-69 and torpedoed the Royal Navy Tank Landing ship HMS LST-404, 35 miles South East of St. Catherine's Point causing extensive damage and seven fatalities. Although the vessel was beached, she later broke in two and was declared a total loss.[3] Convoy escorts counter-attacked; the corvette HMS Orchis is credited with the destruction of U-741. Orchis rescued one survivor.[1]

The wreck was identified by marine archaeologist Innes McCartney in 2000 near the position given by the Allies.

In five patrols U-741 accounted for the total loss of one warship, for a total of 1,625 tons.

Wolfpacks[edit]

U-741 took part in six wolfpacks, namely.

  • Coronel 1 (14–17 December 1943)
  • Sylt (18–23 December 1943)
  • Rügen 2 (23–28 December 1943)
  • Rügen 1 (28 December 1943 – 7 January 1944)
  • Rügen (7–14 January 1944)
  • Preussen (7–22 March 1944)
