German submarine U-627 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. Its hull was laid down on 8 August 1941 at the yards of Blohm & Voss in Hamburg and it was Commissioned on 18 June 1942 under the command of Kapitänleutnant Robert Kindelbacher.

U 627 was sunk on 27 October 1942 just south of Iceland in position 59°14′N 22°49′W / 59.233°N 22.817°W / 59.233; -22.817 by depth charges from a British B-17 Flying Fortress bomber from 206 Squadron RAF. This resulted in the loss of all 44 crew members.

Design[edit]

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-627 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[1] It had a total length of 220 ft 2 in (67.11 m), a pressure hull length of 165 ft 8 in (50.50 m), a beam of 20 ft 4 in (6.20 m), a height of 31 ft 6 in (9.60 m), and a draught of 15 ft 7 in (4.75 m). The submarine was powered by two Friedrich Krupp Germaniawerft M6V 40/46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,100 to 2,400 kW; 2,800 to 3,200 shp) for use while surfaced, two Siemens-Schuckert GU 343/38-8 electric motors or Garbe, Lahmeyer & Co. RP 137/c electric motors producing a total of 750 metric horsepower (740 shp; 550 kW) for use while submerged. It had two shafts and two 1.23 m (4.0 ft) propellers. It was capable of operating at depths of up to 230 metres (750 ft).[1]

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).[1] 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-627 was fitted with five 21 inches (53 cm) torpedo tubes (four fitted at its bow and one at its stern), fourteen torpedoes, one 8.8 centimetres (3.5 in) deck machine gun, 220 rounds, and an anti-aircraft gun. It had a complement of between forty-four and fifty-two.[1]
