German submarine U-239 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

The submarine was laid down on 14 May 1942 at the Friedrich Krupp Germaniawerft yard at Kiel as yard number 669, launched on 28 January 1943 and commissioned on 13 March under the command of Leutnant zur See Ulrich Vöge.[3]

After training with the 5th U-boat Flotilla at Kiel, she went to the 22nd flotilla as a 'school' boat and then back to the 5th flotilla.

She was damaged in Kiel by British bombs in July 1944 and broken up in the same year.

Design[edit]

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-239 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[2] It 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. It had two shafts and two 1.23 m (4 ft) propellers. It 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, it could operate for 80 nautical miles (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, it could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 10 knots (19 km/h; 12 mph). U-239 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at its bow and one at its stern), fourteen torpedoes, one 8.8 cm (3.46 in) SK C/35 naval gun, 220 rounds, and an anti-aircraft gun. It had a complement of between forty-four and fifty-two.[2]

Fate[edit]

She was damaged in a British air raid at the Germania Werke in Kiel on 24 July 1944 which also killed one crewman,[4] she was then broken up later that same year.
