German submarine U-732 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 6 October 1941 at the Schichau-Werke yard at Danzig, launched on 18 August 1942, and commissioned on 24 October 1942 under the command of Oberleutnant zur See Claus-Peter Carlsen.
Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-732 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[1] 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).[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, 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-732 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.[1]
Service history
Attached to 8th U-boat Flotilla based at Danzig, U-732 completed her training period on 30 April 1943 and was assigned to front-line service.
On the third and final war patrol, U-732 was spotted in the afternoon of 31 October 1944 by the British anti-submarine trawler HMT Imperialist off Tangiers. Imperialist made several attacks, throwing a total of 28 depth charges, but was unable to destroy the U-boat. U-732 managed to dive and lay in 180 meters on the sea ground until the oxygen level and became critically low and the batteries were almost discharged. The hopes to escape their pursuers on the surface, were shattered by the presence of HMS Douglas, a British destroyer in the proximity. In the face of the situation, Carlsen decided at 22:30h to order the crew to abandon ship and scuttle the U-boat. Although all crew members made it off U-732, the heavy swell in near total darkness took a heavy toll, only 19 crew members were picked up while 31 perished in the event.[2]
