German submarine U-955 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

Contents

She was ordered on 10 April 1941, and was laid down on 23 February 1942 at Blohm & Voss, Hamburg, as yard number 155. She was launched on 14 November 1942 and commissioned under the command of Oberleutnant zur See Hans-Heinrich Baden on 31 December 1942. [2]

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-955 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 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). [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-955 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes or 26 TMA mines, one 8.8 cm (3.46 in) SK C/35 naval gun, 220 rounds, and one twin 2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of between 44 — 52 men. [3]

Service history

On 30 April 1944, U-955 landed Ernst Fresenius, Sigurður Juliusson and Hjalti Björnsson, espionage agents, on Iceland. [2]

U-955 was located by radar on 5 May 1944, from a British B-24 Liberator, FK226, of 86 Squadron/G RAF piloted by W/O M.G. Moseley and spotted in the moonlight. After several attempts to get the Liberator into a favourable up-moon attack run contact with U-955 was lost. She had apparently made a crash dive after firing at B-24, which she later claimed at shooting down, even though the B-24 was not hit in the encounter. [2]

On 7 June 1944, U-955 was sunk by depth charges, north of Cape Ortegal, Spain in the Bay of Biscay, from a British Sunderland of 201 Squadron/S RAF. Her crew of 50 were all lost. [2]

The wreck is located at 45°13′N08°30′W / 45.217°N 8.500°W / 45.217; -8.500 . [2]
