Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-665 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 Siemens-Schuckert GU 343/38–8 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-665 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
The boat's career began with training at 5th U-boat Flotilla on 22 July 1942, followed by active service on 1 February 1943 as part of the 1st Flotilla for the remainder of her short service. In her sole patrol she sank one merchant ship, for a total of 7,134 gross register tons (GRT).
Wolfpacks
U-665 took part in three wolfpacks, namely
- Neuland (4–6 March 1943)
- Ostmark (6–11 March 1943)
- Stürmer (11–20 March 1943)
Fate
U-665 was sunk on 22 March 1943 in the North Atlantic at Lua error in package.lua at line 80: module 'strict' not found., by depth charges from an Armstrong Whitworth Whitley VII of No. 10 Operational Training Unit RAF (10 OTU) (call-sign Q), for the loss of all hands.
