Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-387 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 Garbe, Lahmeyer & Co. RP 137/c 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-387 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.
Service history
The submarine was laid down on 5 September 1941 at the Howaldtswerke yard at Kiel as yard number 18, launched on 1 October 1942 and commissioned on 24 November under the command of Kapitänleutnant Rudolf Büchler.
She served with the 5th U-boat Flotilla from 24 November 1942 and the 7th flotilla from 1 July 1943. She was reassigned to the 13th flotilla from 1 November until her loss.
1st patrol
U-387's first patrol was preceded by short trips from Kiel to Marviken, then to Bergen in June 1943. The boat's patrol proper commenced with her departure from Bergen on 3 July. She followed the Norwegian coast as far as Bodø and then headed due north as far as a point a few miles short of Svalbard. She then sailed south, passing to the west of Bear Island, docking in Narvik on 21 August. At 50 days, it was her longest patrol, but sighting the enemy did not happen.
2nd and 3rd patrols
The boat's second and third sorties were both divided into two parts. Her crew got to know the northern Norwegian, Greenland and Barents Seas particularly well.
4th, 5th and 6th patrols
The monotony of her fourth, fifth and sixth forays was not relieved by success.
7th patrol
By now based in Narvik, the submarine was carrying out her seventh patrol when she was attacked by a Norwegian-crewed Sunderland flying boat of No. 330 Squadron RAF. Enough damage was inflicted to oblige the U-boat to put into Trondheim for repairs.
8th and 9th patrols
U-387's eighth patrol was uneventful as was her ninth, which took her to the waters around the North Cape.
10th patrol and loss
The boat left Narvik for the last time on 24 November 1944. On 9 December, she was sunk in the Barents Sea near Murmansk by depth charges dropped by the British corvette HMS Bamborough Castle.
Fifty-one men died in the U-boat; there were no survivors.
Wolfpacks
U-387 took part in eleven wolfpacks, namely.
