Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-587 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 Brown, Boveri & Cie 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).

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-587 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.

Service history

The boat's short service career began on 11 September 1941 with training, followed by active service on 1 January 1942 as part of the 6th U-boat Flotilla. It ended just 3 months later when she was sunk in the North Atlantic.

In two patrols she sank four merchant ships, for a total of 22,734 gross register tons (GRT), plus one auxiliary warship sunk.

Wolfpacks

U-587 took part in one wolfpack, namely:

• Robbe (15 – 24 January 1942)

Fate

U-587 was sunk on 27 March 1942 in the North Atlantic in position 47°21′N 21°39′W; depth charged by Royal Navy vessels HMS Grove, Aldenham, Volunteer and Leamington. There were no survivors.
