German submarine U-13 was a Type IIB U-boat of Nazi Germany's Kriegsmarine which was commissioned on 30 November 1936, following construction at the Deutsche Werke shipyards at Kiel. The first commander on board was Hans-Gerrit von Stockhausen. In her career she completed nine patrols, all while serving with the 1st U-boat Flotilla. The U-boat succeeded in sinking nine ships and damaging three more.

Design

German Type IIB submarines were enlarged versions of the original Type IIs. U-13 had a displacement of 279 tonnes (275 long tons) when at the surface and 328 tonnes (323 long tons) while submerged. Officially, the standard tonnage was 250 long tons (250 t), however.^[1] The U-boat had a total length of 42.70 m (140 ft 1 in), a pressure hull length of 28.20 m (92 ft 6 in), a beam of 4.08 m (13 ft 5 in), a height of 8.60 m (28 ft 3 in), and a draught of 3.90 m (12 ft 10 in). The submarine was powered by two MWM RS 127 S four-stroke, six-cylinder diesel engines of 700 metric horsepower (510 kW; 690 shp) for cruising, two Siemens-Schuckert PG VV 322/36 double-acting electric motors producing a total of 460 metric horsepower (340 kW; 450 shp) for use while submerged. She had two shafts and two 0.85 m (3 ft) propellers. The boat was capable of operating at depths of up to 80–150 metres (260–490 ft).^[1]

The submarine had a maximum surface speed of 12 knots (22 km/h; 14 mph) and a maximum submerged speed of 7 knots (13 km/h; 8.1 mph).^[1] When submerged, the boat could operate for 35–42 nautical miles (65–78 km; 40–48 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 3,800 nautical miles (7,000 km; 4,400 mi) at 8 knots (15 km/h; 9.2 mph). U-13 was fitted with three 53.3 cm (21 in) torpedo tubes at the bow, five torpedoes or up to twelve Type A torpedo mines, and a 2 cm (0.79 in) anti-aircraft gun. The boat had a complement of twentyfive.^[1]

Fate

U-13 was sunk on 31 May 1940, in the North Sea 11 nautical miles (20 km) south-east of Lowestoft, in position 52°26′N 02°02′E / 52.433°N 2.033°E / 52.433; 2.033Coordinates: 52°26′N 02°02′E / 52.433°N 2.033°E / 52.433; 2.033 by depth charges from the British sloop HMS Weston. There were no casualties.
