German submarine U 592

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-592 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 Brown, Boveri & Cie GG UB 720/8 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-592 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.

Service history

The submarine was laid down on 30 October 1940 at Blohm & Voss, Hamburg as yard number 568, launched on 20 August 1941 and commissioned on 16 October under the command of Kapitänleutnant Carl Borm.

She served with the 6th U-boat Flotilla from 16 October 1941 for training and stayed with that organization for operations from 1 February 1942. She was reassigned to the 11th flotilla on 1 July, then back to the 6th flotilla from 1 March 1943.

1st and 2nd patrols

U-592's first patrol was preceded by a short trip from Hamburg to the German-controlled island of Helgoland, (also known as Heligoland), in February 1942. The patrol itself commenced on 3 March. She steamed up the Norwegian side of the North Sea and arrived at Bergen on 23 March.

For her second foray, she covered the Norwegian and Barents Seas.

3rd patrol

Her third sortie was preceded by brief voyages from Bergen to Hamburg, then Kiel and back to Bergen. The patrol itself commenced with the boat's departure from the Norwegian port on 17 July 1942. She covered vast swathes of the Norwegian Sea before putting into Skjomenfjord, (south of Narvik), on 14 August.

4th patrol

U-592 covered the areas toward Spitsbergen (Svalbard) and Iceland.

5th patrol

The boat left Skjomenfjord on 7 October 1942. On the 14th, she scored her only success when she sank the Soviet ship Shchors with a mine off the western entrance to the Yugar Strait. This ship was being towed toward Belushja Bay when she sank in 11 m (36 ft) of water.

6th patrol

This patrol, in November and December 1942, was relatively uneventful. The boat moved from Narvik to Bergen in mid-December.

7th patrol

U-592 left Bergen on 9 March 1943, bound for the French Atlantic coast. Moving through the gap between Iceland and the Faroe Islands, she entered the Atlantic Ocean and patrolled southeast of Greenland before entering St. Nazaire on 18 April.

8th and 9th patrols

These two sorties were also fairly trouble-free; between May and November 1943.

10th patrol and loss

The submarine had left St. Nazaire on 10 January 1944. On the 31st, she was sunk by depth charges, in position 50°20′N 17°29′W, from ships of the 2nd Support Group - HMS Starling, Wild Goose and Magpie, southwest of Ireland.

Forty-nine men died with U-592; there were no survivors.

Wolfpacks

U-592 took part in 16 wolfpacks, namely.
