German submarine U-710 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

Ordered 15 August 1940, she was laid down 4 June 1941 and launched 12 May 1942. She had a relatively brief career from 2 September 1942 until 1 April 1943 as part of a training flotilla, then on active service from 1 April 1943 till 24 April 1943. During this time she was commanded by Oberleutnant zur See Dietrich von Carlowitz.

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-710 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[2] 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 Garbe, Lahmeyer & Co. RP 137/c 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).[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, 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-710 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 two twin 2 cm (0.79 in) C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.[2]

Patrol history

During her 24-day active service career, U-710 sunk no ships. She was destroyed by depth charges on 24 April 1943. by a British Boeing B-17 Flying Fortress, from No. 206 Squadron RAF. Lost with all hands, 49 dead.
