Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-1051 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged. [2] 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). [2]

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). [2] 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-1051 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), one 3.7 cm (1.5 in) Flak M42 and two twin 2 cm (0.79 in) C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty. [2]

Service history

The boat's career began with training at 5th U-boat Flotilla on 4 March 1944, followed by active service on 1 January 1945 as part of the 11th Flotilla and was sunk just three weeks later on her first patrol.

In one patrol she sank one merchant ship, for a total of 1,152  gross register tons  (GRT) and one warship total loss for 1,300 tons.

Wolfpacks

U-1051 took part in no wolfpacks.

Fate

U-1051 was sunk on 26 January 1945 in the Irish Sea in position 53°39′N05°23′W / 53.650°N 5.383°W / 53.650; -5.383 , by ramming and depth charges from Royal Navy frigates HMS Aylmer, HMS Calder, HMS Bentinck, and HMS Manners. All hands were lost.
