German submarine U-572 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. Her keel was laid down 15 June 1940 at the Blohm & Voss yard in Hamburg as yard number 548. She was launched on 5 April 1941 and commissioned on 29 May.
Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-572 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 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).
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-572 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
U-572 undertook nine patrols before it was sunk by an Allied marine aircraft in the Mid Atlantic in 1943.
The boat made an attempt to enter the Mediterranean but the commander gave up after a long period submerged in the heavy defences at Gibraltar and stated that he considered that his boat had been damaged and therefore he could not continue. However, Kapitänleutnant Heinz Hirsacker was reported by his senior watch officer for alleged cowardice. He was found guilty of "cowardice in the presence of the enemy" by courts marshall. On 24 April 1943 he committed suicide shortly before his execution.[3] The U Boat was depth charged and sunk by a US Martin PBM Mariner from VP-205 NE of Trinidad on 3 August 1943, in position 11°35′N 54°05′W / 11.583°N 54.083°W / 11.583; -54.083. All 47 crew members died.

U-572 took part in eleven wolfpacks, namely:
- Brandenburg (15 September – 1 October 1941)
- Störtebecker (5 – 19 November 1941)
- Gödecke (19 – 26 November 1941)
- Hai (3 – 21 July 1942)
- Streitaxt (20 October – 2 November 1942)
- Schlagetot (9 – 16 November 1942)
- Falke (28 December 1942 – 19 January 1943)
- Landsknecht (19 – 28 January 1943)
