German submarine U-274 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-274 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-274 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]

Service history

U-274 served with the 8th U-boat Flotilla for training from November 1942 to July 1943 and operationally with the 7th U-boat Flotilla from 1 August 1943.^[1] She carried out two patrols, but sank no ships.

She carried out short voyages between Kiel in Germany and Bergen and Trondheim in Norway over August 1943.

First patrol

The boat departed Trondheim on 1 September 1943 and returned to the Norwegian port twelve days later on the 13th.

Second patrol and loss

For her second sortie, the boat headed toward the Atlantic Ocean, via the gap between Iceland and the Faroe Islands. She was sunk by Hedgehog and depth charges dropped by the British destroyers HMS Duncan and HMS Vidette and a B-24 Liberator of No. 224 Squadron RAF on 23 October 1943.

The pilot of the Liberator was a Swiss national serving in the RAF. The intercom in the aircraft had been inadvertently left connected to the radio. As a result, ships of the nearby convoy escort heard an improvised commentary which was a great encouragement.^[4]^[1]
