Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-667 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-667 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.^[2]

Service history

The boat's career began with training at 5th U-boat Flotilla on 21 October 1942, followed by active service on 1 June 1943 as part of the 7th Flotilla for the remainder of her service.

In five patrols she sank one merchant ship, for a total of 7,176 gross register tons (GRT) and 2 warships. She also cause one warship total loss.

Wolfpacks

U-667 took part in five wolfpacks, namely:

Coronel (4 – 8 December 1943)
Coronel 2 (8 – 14 December 1943)
Coronel 3 (14 – 17 December 1943)
Borkum (18 – 26 December 1943)
Preussen (13 – 22 March 1944)

Fate

U-667 sunk on 26 August 1944 in the Bay of Biscay in position 46°04′N01°03′W / 46.067°N 1.050°W / 46.067; -1.050 , when she struck a mine. All hands were lost.
