.

The submarine was laid down on 9 January 1942 at the Bremer Vulkan yard at Bremen-Vegesack as yard number 39. She was launched on 19 September 1942 and commissioned on 7 November under the command of Oberleutnant zur See Günther Jordan.[1]

Design

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).

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

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]
