Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-752 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[1] 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).[1]
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).[1] 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-752 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.[1]
Service history
She served with 3rd U-boat Flotilla from 24 May 1941 to 23 May 1943 under the command of Karl-Ernst Schroeter.[2] U-752 completed nine[3] wartime patrols and sank eight ships and damaged one.
Fate
Thirty-two days into her ninth patrol, on 23 May 1943, U-752 was attacked by Fairey Swordfish aircraft attached to the British escort carrier HMS Archer in the mid-Atlantic. A Rocket Spear, a new weapon with a solid cast iron head,[4] entered and left the pressure hull leaving large holes, thus preventing the U-boat from diving. At the arrival of enemy surface craft, the surviving crew of 17 scuttled the boat and abandoned ship.[5] This was the first success of the Rocket Spear. U-752 sank with 30 men. Heinz Krey was one of them.
Wolfpacks
U-752 took part in ten wolfpacks, namely.
- Westwall (2–12 March 1942)
- Hai (3–21 July 1942)
- Schlagetot (9–21 November 1942)
- Habicht (10–19 January 1943)
- Haudegen (19 January – 9 February 1943)
- Amsel 3 (4–6 May 1943)
- Rhein (7–10 May 1943)
- Elbe 1 (10–14 May 1943)
- Oder (17–19 May 1943)
- Mosel (19–23 May 1943)
