German Submarine U-336
Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-336 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged. 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).
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). 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-336 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 a 2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.
Service history
After training with the 5th U-boat Flotilla, she moved to the 1st flotilla for front-line service in December 1942.
The boat carried out five patrols, sinking one ship.
She was a member of ten wolfpacks.
First patrol
The boat's first patrol was very brief; starting and finishing in Kiel on 12 and 13 November 1942.
Second patrol
Her second foray also started in Kiel, but terminated in Brest in occupied France after passing between the Faroe and Shetland Islands. She sank the Belgian tanker President Francqui on 29 December 1942 north of the Azores. The ship had already been hit by two torpedoes. U-336 finished her off with a 'coup de grâce'.
Third patrol
The submarine's third sortie was again into the mid-Atlantic. She spent days scouring the empty wastes, but returned to Brest without success.
Fourth patrol
U-336's fourth patrol was, at 71 days, her longest. She was attacked by an unidentified aircraft on 10 July 1943 west of Lisbon. Slight damage was the result.
Fifth patrol
U-336 left Brest for the last time on 14 September 1943. Initially she headed west, out of the Bay of Biscay. On the 24th, she turned north.
Fate
On 5 October, she was sunk by rockets fired by a British Lockheed Hudson of No. 269 Squadron RAF in the Denmark Strait, (between Greenland and Iceland).
Fifty men died; there were no survivors.
Wolfpacks
U-336 took part in ten wolfpacks, namely:
- Ungestüm (11 – 30 December 1942)
- Neuland (8 – 13 March 1943)
- Dränger (14 – 20 March 1943)
- Seewolf (21 – 30 March 1943)
- Oder (17 – 19 May 1943)
- Mosel (19 – 24 May 1943)
- Trutz (1 – 16 June 1943)
- Trutz 2 (16 – 29 June 1943)
- Geier 3 (30 June – 10 July 1943)
- Rossbach (24 September – 5 October 1943)
