She was laid down on 10 June 1941 by Deutsche Werft , Hamburg as yard number 814, launched on 9 June 1942 and commissioned on 22 July 1942 under Leutnant zur See Hans-Jürgen Haupt.
Design
[ edit ]
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. 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 ).
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-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 two twin 2 cm (0.79 in ) C/30 anti-aircraft guns . The boat had a complement of between forty-four and sixty.
Service history
[ edit ]
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
[ edit ]
U-665 took part in three wolfpacks , namely:
Neuland (4 – 6 March 1943)
Ostmark (6 – 11 March 1943)
Stürmer (11 – 20 March 1943)
