Design edit

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-969 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 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).[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-969 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.[2]

Service history edit

The boat's career began with training at 5th U-boat Flotilla on 24 March 1943, followed by active service on 1 October 1943 as part of the 7th Flotilla for the next five months. She transferred to 29th Flotilla, on 1 March 1944, based in La Spezia, for Mediterranean operations.

Wolfpacks edit

U-969 took part in seven wolfpacks, namely:

  • Siegfried (22 – 27 October 1943)
  • Siegfried 1 (27 – 30 October 1943)
  • Körner (30 October – 2 November 1943)
  • Tirpitz 2 (2 – 8 November 1943)
  • Eisenhart 3 (9 – 15 November 1943)
  • Schill 2 (17 – 22 November 1943)
  • Weddigen (22 November – 4 December 1943)

Fate edit

U-969 was sunk on 6 August 1944 in the Military port of Toulon in position 43°07′N 05°55′E / 43.117°N 5.917°E / 43.117; 5.917 in an air raid by US Liberator bombers.
