German submarine U-342 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

She was on her first patrol when she was sunk by a Canadian aircraft, Canso patrol flying boats, on 17 April 1944, with 51 casualties, lost with all hands.

She did not sink or damage any ships.

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-342 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[4] 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).[4]

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).[4] 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-342 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.[4]

Service history

The submarine was laid down on 7 December 1941 at the Nordseewerke yard at Emden as yard number 214, launched on 10 November 1942 and commissioned on 12 January 1943 under the command of Oberleutnant zur See Albert Hossenfelder.

U-342 served with the 8th U-boat Flotilla, for training and then with the 7th flotilla for operations from 1 March 1944.

Patrol

U-342 had sailed from Kiel in Germany to Bergen in Norway in March 1944, but her patrol began when she departed Bergen on 3 April and headed for the Atlantic Ocean. She had passed through the gap between Iceland and the Faroe Islands, but was attacked and sunk by a Canadian Canso (PBY Catalina) of No. 162 Squadron RCAF southwest of Iceland on 17 April.[1]

Fifty-one men died; there were no survivors.[5]
