Her keel was laid down on 15 March 1936 by DeSchiMAG AG Weser of Bremen as yard number 913. She was launched on 25 February 1937 and commissioned on 15 April with Kapitänleutnant Werner Lott in command. On 15 August 1937, Lott was relieved by Korvettenkapitän Paul Büchel, and on 12 February 1940, Oberleutnant zur See Hans Jenisch took over. He was in charge of the boat until her loss.[1]

Design

edit

As one of the first ten German Type VII submarines later designated as Type VIIA submarines, U-32 had a displacement of 626 tonnes (616 long tons) when at the surface and 745 tonnes (733 long tons) while submerged.[3] She had a total length of 64.51 m (211 ft 8 in), a pressure hull length of 45.50 m (149 ft 3 in), a beam of 5.85 m (19 ft 2 in), a height of 9.50 m (31 ft 2 in), and a draught of 4.37 m (14 ft 4 in). The submarine was powered by two MAN M 6 V 40/46 four-stroke, six-cylinder diesel engines producing a total of 2,100 to 2,310 metric horsepower (1,540 to 1,700 kW; 2,070 to 2,280 shp) for use while surfaced, two BBC 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).[3]

The submarine had a maximum surface speed of 17 knots (31 km/h; 20 mph) and a maximum submerged speed of 8 knots (15 km/h; 9.2 mph).[3] When submerged, the boat could operate for 73–94 nautical miles (135–174 km; 84–108 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 6,200 nautical miles (11,500 km; 7,100 mi) at 10 knots (19 km/h; 12 mph). U-32 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at the bow and one at the stern), eleven 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.[3]

Service history

edit

U-32 conducted nine patrols, sinking 20 ships, for a total of 116,836 gross register tons (GRT) and damaging five more, totalling 32,274 GRT and 8,000 tons. On 28 October 1940 U-32, under the command of Hans Jenisch, sank the 42,348 GRT liner Empress of Britain, which had been previously damaged by German bombs. Empress was the largest ship sunk by a U-boat.[1]

Fate

edit

U-32 was sunk northwest of Ireland, in position 55°37′N 12°19′W / 55.617°N 12.317°W / 55.617; -12.317, by depth charges from the British destroyers Harvester and Highlander on 30 October 1940. Nine crew members were killed; 33 survived and became prisoners of war, including Jenisch. Jenisch then spent six and a half years in British captivity before returning to Germany in June 1947.[1][4]

Wolfpacks

edit

U-32 took part in one wolfpack, namely:

  • Prien (12 – 17 June 1940)
