German submarine U-660 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. She was laid down on 15 February 1941 by Howaldtswerke, Hamburg as yard number 809, launched on 17 November 1941 and commissioned on 8 January 1942 under Oberleutnant zur See Götz Baur.
Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-660 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-660 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 8 January 1942, followed by active service on 1 August 1942 as part of the 9th Flotilla. Later, on 1 November 1942, she transferred to operations in the Mediterranean with 29th Flotilla where she served for the remainder of her service.
In 3 patrols she sank 2 merchant ships, for a total of 10,066 gross register tons (GRT), and damaged 2 others.
Wolfpacks
U-660 took part in four wolfpacks, namely
- Steinbrinck (6 August 1942 – 11 August 1942)
- Lohs (11 August 1942 – 28 August 1942)
- Tümmler (3 October 1942 – 11 October 1942)
- Wal (10 November 1942 – 12 November 1942)
Fate
U-660 was scuttled on 12 November 1942 in the Mediterranean in position 36°07′N 01°00′W / 36.117°N 1.000°W, after sustaining damage by depth charges from HMS Lotus and HMS Starwort.
