German Submarine U-992

German submarine U-992 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. She was laid down on 30 October 1942 by Blohm & Voss, Hamburg as yard number 192, launched on 24 June 1943 and commissioned on 2 August 1943 under Oberleutnant zur See Hans Falke.

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-992 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 Brown, Boveri & Cie GG UB 720/8 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-992 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 twin 2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.

Service history

The boat's career began with training at 5th Flotilla on 2 August 1943, followed by active service on 1 March 1944 as part of the 3rd Flotilla. She later transferred to 11th Flotilla on 1 June 1944, then on to 13th Flotilla on 1 October 1944.

U-992 took part in seven wolfpacks, namely:

  • Trutz (1 June – 10 July 1944)
  • Dachs (1 – 5 September 1944)
  • Zorn (28 September – 1 October 1944)
  • Grimm (1 – 2 October 1944)
  • Panther (20 October – 9 November 1944)
  • Stier (5 – 7 December 1944)
  • Hagen (17 – 21 March 1945)
