German submarine U-568 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. She was laid down on 27 April 1940 by Blohm & Voss in Hamburg as yard number 544, launched on 6 March 1941 and commissioned on 1 May 1941 under Kptlt. Joachim Preuss.

Design[edit]

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-568 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 BBC 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).[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-568 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[edit]

The boat's service began on 1 May 1941 with training as part of the 3rd U-boat Flotilla. She transferred to the 29th Flotilla on 1 January 1942 for active service, in the Mediterranean.

In five patrols she sank one merchant ship, two warships and damaged one warship.

Wolfpacks[edit]

She took part in four wolfpacks, namely

  • Grönland (10 – 23 August 1941)
  • Kurfürst (23 August – 2 September 1941)
  • Seewolf (2 – 8 September 1941)
  • Reissewolf (21 – 31 October 1941)

Fate[edit]

U-568 was sunk on 29 May 1942 in the Mediterranean Sea NE of Tobruk in position 32°42′N 24°53′E / 32.700°N 24.883°E / 32.700; 24.883, by Royal Navy vessels, the destroyer HMS Hero, and escort destroyers HMS Eridge and HMS Hurworth. All 47 hands survived.[3]
