Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-447 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 460/8-276 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).[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-447 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 a 2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.[2]

Service history

The boat's career began with training at 8th U-boat Flotilla on 11 July 1942, followed by active service on 1 March 1943 as part of the 9th Flotilla for the remainder of her service. In 2 patrols she sank no ships.[1]

Wolfpacks

U-447 took part in three wolfpacks, namely:

  • Neuland (4 – 6 March 1943)
  • Ostmark (6 – 11 March 1943)
  • Drossel (29 April – 7 May 1943)

Fate

U-447 was sunk on 7 May 1943 in the North Atlantic in position 35°30′N 11°55′W / 35.500°N 11.917°W / 35.500; -11.917, by depth charges from 2 RAF Hudson bombers from 233 Squadron. All crew members died.[1]
