German submarine U-271 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 21 October 1941 at the Bremer Vulkan yard at Bremen-Vegesack as yard number 36, launched on 29 July 1942 and commissioned on 23 September under the command of Kapitänleutnant Curt Barleben. After training with the 8th U-boat Flotilla, U-271 was transferred to the 1st U-boat Flotilla, for front-line service from 1 June 1943.
U-271 sank no ships in her short career. She was a member of two wolfpacks.
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-271 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 460/8–27 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-271 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.[3]
The boat's initial foray started and finished in Lorient in occupied France. It was relatively uneventful.
It was a different story on her second patrol. While serving as a 'Flak' boat, U-271 was attacked by two TBM Avengers from the USS Core on 21 October 1943. One man died.
She was also attacked by a B-24 Liberator on 24 June south southeast of Cape Finisterre. The aircraft was shot down. The submarine sustained some damage.
U-271 set off from Brest for the last time on 12 January 1944. On the 28th she was attacked and sunk west of Limerick in Ireland by a US Navy PB4Y-1 Liberator of VB-103.
Fifty-one men died; there were no survivors.
U-271 took part in two wolfpacks, namely:
53°15′00″N 15°52′00″W / 53.2500°N 15.8667°W / 53.2500; -15.8667
