German submarineU-427 was aType VIIC U-boat ofNazi Germany'sKriegsmarine duringWorld War II.

Design

[edit]

German Type VIIC submarines were preceded by the shorterType VIIB submarines.U-427 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), apressure hull length of 50.50 m (165 ft 8 in), abeam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and adraught of 4.74 m (15 ft 7 in). The submarine was powered by twoGermaniawerft F46 four-stroke, six-cylindersupercharged 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, twoSiemens-Schuckert GU 343/38–8double-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-427 was fitted with five 53.3 cm (21 in)torpedo tubes (four fitted at the bow and one at the stern), fourteentorpedoes, one8.8 cm (3.46 in) SK C/35 naval gun, 220 rounds, and two twin2 cm (0.79 in) C/30 anti-aircraft guns. The boat had acomplement of between forty-four and sixty.^[3]

Service history

[edit]

Built byDanziger Werft,Danzig, the U-boat waslaid down on 27 July 1942,launched on 6 February 1943 andcommissioned on 2 June 1943 with a crew of 53 under theirAustrian commanderOberleutnant Carl-GabrielGraf von Gudenus. It survived until the end of the war. MostU-boats achieved notoriety for the number of kills they achieved, or the total tonnage of the vessels they sank, but in the case ofU-427 fame was achieved differently.^[4]

From its first voyage, on 20 June 1944, until the end of the war,U-427 never destroyed any of its targets. It firedtorpedoes at two vessels,HMCS Haida andHMCS Iroquois on 29 April 1945, missing both, but it was for its ability to survive under harrowing circumstances thatU-427 became known. In April 1945, leading up to, during, and after those two attacks,U-427 survived 678depth charge attempts. On 2 May 1945,U-427 returned to its base atKilbotn, Norway, where it remained for the few remaining days before Germany's surrender.^[4]^[5]^[6]

U-427 surrendered atNarvik, Norway, on 9 May 1945, and was transferred toLoch Eriboll, Scotland, on 19 May, and later toLoch Ryan as part of "Operation Deadlight" when it was sunk on 21 December 1945 at56°04′N09°35′W / 56.067°N 9.583°W /56.067; -9.583.
