Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-565 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-565 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. [2]

Service history

The boat's service began on 10 April 1941 with training as part of the 1st U-boat Flotilla. She was transferred to the 29th flotilla on 1 January 1942 in the Mediterranean where she remained until being scuttled in 1944. In 20 patrols she sank three merchant ships, for a total of 11,347  gross register tons  (GRT), plus two warships sunk and another two merchant ships damaged. [3]

She took part in two wolfpacks, namely:

Fate

U-565 was badly damaged by bombs dropped by US aircraft on 19 and 24 September 1944 in the Mediterranean near Skaramanga in Greece. She was scuttled on 30 September 1944 at Skaramanga Bay.
