German submarine U-357 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II and was sunk by British warships northwest of Ireland on 26 December 1942 on her first operational patrol.

Design

[edit]

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-357 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[3] 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).[3]

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).[3] 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-357 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.[3]

Service history

[edit]

The submarine was laid down on 19 May 1940 at the Flensburger Schiffbau-Gesellschaft yard at Flensburg as yard number 476, launched on 31 March 1942 and commissioned on 18 June under the command of Kapitänleutnant Adolf Kellner.

She served with the 8th U-boat Flotilla from 18 June 1942 and the 6th flotilla from 1 December.

Fate

[edit]

U-357 was sunk by depth charges dropped from the British destroyers HMS Hesperus and Vanessa on 26 December 1942 northwest of Ireland.[1][4]

36 men died; six survived.[2]
