German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-585 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-585 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.
The submarine was laid down on 1 October 1940 at Blohm & Voss, Hamburg as yard number 561, launched on 9 July 1941 and commissioned on 28 August under the command of Kapitänleutnant Ernst-Bernward Lohse.
She served with the 6th U-boat Flotilla from 28 August 1941 for training and stayed with that organization for operations until her loss, from 1 December 1941 to 30 March 1942.
U-585's first patrol was preceded by a trip to Trondheim then Neidenfjord [west northwest of Murmansk], both in Norway over Christmas and New Year's Eve 1941-42. The patrol itself started in Neidenfjord on 15 January 1942 and finished in Kirkenes on the 21st.
Her second foray was notable for the loss overboard of Fahnrich zur See [midshipman] Eberhard Vollmer on 5 February 1942 in the southern Barents Sea.
The boat was attacked with depth charges by three enemy ships northeast of Kirkenes on 24 March 1942. The damage to the forward torpedo tubes was serious enough to require the submarine to return to her base.
4th patrol and loss
While in Varanfjord, the Soviet submarine M-171 fired both of her torpedoes at an unknown, but outbound U-boat. This can only have been U-585, although she did not report any attack.
She was sunk on 30 March 1942 by a German mine that had drifted from the 'Bantos-A' barrage.
Forty-four men died with U-585; there were no survivors.
Previously recorded fate
The boat was also claimed to be sunk by the Soviet destroyer Gremyashiy on 30 March 1942. This attack was against U-435 and was also inconclusive.
