German submarine U-86 was a Type VIIB U-boat of Nazi Germany's Kriegsmarine during World War II.

She was laid down at the Flender Werke in Lübeck on 20 January 1940 as yard number 282. Launched on 10 May 1941, she was commissioned on 8 July and completed training with the 5th U-boat Flotilla under the command of Kapitänleutnant (Kptlt.) Walter Schug. She was reassigned to the 1st flotilla, initially for further training on 1 September before being ready for operations from 1 December. She stayed with that organization until her loss on 29 November 1943.

U-86 completed eight war patrols with the flotilla, sinking three ships, totalling 9,614 gross register tons (GRT). She also damaged a ship of 8,627 GRT. She was a member of ten wolfpacks.

She was sunk in November 1943 by two British warships.

Design

German Type VIIB submarines were preceded by the shorter Type VIIA submarines. U-86 had a displacement of 753 tonnes (741 long tons) when at the surface and 857 tonnes (843 long tons) while submerged.[1] It had a total length of 66.50 m (218 ft 2 in), a pressure hull length of 48.80 m (160 ft 1 in), a beam of 6.20 m (20 ft 4 in), a height of 9.50 m (31 ft 2 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two MAN M 6 V 40/46 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 BBC GG UB 720/8 double-acting electric motors producing a total of 750 shaft horsepower (760 PS; 560 kW) for use while submerged. It had two shafts and two 1.23 m (4 ft) propellers. It was capable of operating at depths of up to 230 metres (750 ft).[1]

The submarine had a maximum surface speed of 17.9 knots (33.2 km/h; 20.6 mph) and a maximum submerged speed of 8 knots (15 km/h; 9.2 mph).[1] When submerged, it could operate for 90 nautical miles (170 km; 100 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, it could travel 8,700 nautical miles (16,100 km; 10,000 mi) at 10 knots (19 km/h; 12 mph). U-86 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at its bow and one at its stern), fourteen torpedoes, one 8.8 cm (3.46 in) SK C/35 naval gun, 220 rounds, and one 2 cm (0.79 in) anti-aircraft gun It had a complement of between forty-four and sixty.[1]

Service history

1st patrol

U-86 departed Kiel on 7 December 1941 for her first patrol. She docked at Brest on the French Atlantic coast on the 22nd where she would be based for the rest of her career.

2nd patrol

U-86‍ '​s second patrol started on 27 December 1941. She damaged the British Toorak on 16 January 1942. On the 18th, she sank the Greek Dimitios G. Thermiotis.

3rd and 4th patrols

On her third foray, she left Brest on 25 March 1942. It was relatively uneventful. She returned on 26 May.

Sortie number four began on 2 July 1942. On 6 August, she sank an American sailing ship, the Wawaloam with her deck gun.

5th, 6th and 7th patrols

This (fifth) outing was also quiet, starting on 31 October 1942 and finishing on 7 January 1943.

Having left Brest on 24 February 1943, she encountered and sank her final victim, the Norwegian Brant County on 11 March.

U-86‍ '​s seventh patrol was between 8 July and 11 September 1943.

8th patrol and Loss

The boat departed Brest for the last time on 11 November 1943. She was sunk east of the Azores on the 29 November 1943 by depth charges from the British destroyers HMS Tumult and HMS Rocket.

50 men died; there were no survivors.

Previously recorded fate

U-86 was listed as missing in the North Atlantic from 28 November 1943.
The boat was claimed sunk by aircraft from the USS Bogue on 29 November 1943. This attack was subsequently attributed to U-764 which escaped undamaged.
