German submarine U-763 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. She was laid down on 21 January 1941 by Kriegsmarinewerft Wilhelmshaven as yard number 146, launched on 16 January 1943 and commissioned on 13 March 1943 under Kapitänleutnant Ernst Cordes. On 1 November 1944, Oberleutnant zur See Karl-Heinz Schröter took over command as part of her transfer to 24th Flotilla..

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-763 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 Garbe, Lahmeyer & Co. RP 137/c 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-763 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 an anti-aircraft gun. The boat had a complement of between forty-four and sixty.[2]

Service history

The boat's career began with training at 8th U-boat Flotilla on 13 March 1943, followed by active service on 1 November 1943 as part of the 1st Flotilla. When the situation deteriorated for the Germans in France, on 1 October 1944, following the invasion, she transferred to 33rd Flotilla in Flensburg, but stayed only one month. On 1 November 1944 she transferred to 24th Flotilla for training.

In four patrols she sunk one merchant ship, for a total of 1,927 gross register tons (GRT).

4/5 February 1944

On 4 February 1944, U-763 shot down a RAF Liberator bomber of 53 Squadron in the Bay of Biscay. On the following day, she successfully warded off three separate air attacks by the RAF, resulting in damage to a Liberator of 53 Squadron, a Wellington bomber of 172 Squadron and the loss of a Halifax bomber from 502 Squadron

Wolfpacks

U-763 took part in one wolfpack, namely.

  • Rügen 3 (28–31 December 1943)

Fate

U-763 was scuttled on 29 January 1945 in the Schichau-Werke shipyard, Königsberg in position Lua error in package.lua at line 80: module 'strict' not found. after being damaged in a Soviet air raid.
