German submarine U-85 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 18 December 1939 as yard number 281. Launched on 10 April 1941, she was commissioned on 7 June and assigned to the 3rd U-boat Flotilla under the command of Oberleutnant zur See Eberhard Greger.
U-85 conducted four war patrols with the flotilla, and sank three ships, totalling . She was sunk in April 1942 by the US destroyer Roper.
German Type VIIB submarines were preceded by the shorter Type VIIA submarines. U-85 had a displacement of 753t when at the surface and 857t while submerged. She had a total length of 66.5m (218.2feet), a pressure hull length of 48.8m (160.1feet), a beam of 6.2m (20.3feet), a height of 9.5m (31.2feet), and a draught of 4.74m (15.55feet). The submarine was powered by two MAN M 6 V 40/46 four-stroke, six-cylinder supercharged diesel engines producing a total of NaNPS for use while surfaced, two BBC GG UB 720/8 double-acting electric motors producing a total of 750PS for use while submerged. She had two shafts and two 1.23abbr=onNaNabbr=on propellers. The boat was capable of operating at depths of up to .
The submarine had a maximum surface speed of and a maximum submerged speed of . When submerged, the boat could operate for at ; when surfaced, she could travel at . U-85 was fitted with five 53.30NaN0 torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.82NaN2 SK C/35 naval gun, 220 rounds, and one 2cm (01inches) anti-aircraft gun The boat had a complement of between forty-four and sixty.
U-85 departed Trondheim in Norway on 28 August 1941 for her first patrol. She sank the Thistleglen on 10 September northeast of Cape Farewell (Greenland).
She docked at St. Nazaire on the French Atlantic coast on 18 September.
U-85s second patrol started and finished in Lorient, but was unremarkable.
On her third foray, she sank the southeast of St. Johns, Newfoundland, after a seven-hour chase, on 9 February 1942. Nine crew members were lost.[1]
Having left St. Nazaire on 21 March 1942, U-85 sank the Norwegian freighter Christen Knudsen off the coast of New Jersey on 10 April.[2]
U-85 took part in four wolfpacks, namely:
U-85 was operating within view of Bodie Island Light at midnight on 13 April 1942 when the destroyer detected the submarine on British Type 286 radar at a range of 2700yd. The boat attempted to run south on the surface and fired its stern torpedo as Roper closed to . The destroyer evaded the torpedo and closed to, when U-85 turned sharply to starboard. Roper illuminated the U-boat with its searchlight and observed men on deck near the gun whose firing arc had just been cleared by the course change. Roper raked U-85 with machine gun fire and scored a hit with a 3"/50 caliber gun. Roper then dropped a pattern of 11 depth charges where U-85 had disappeared beneath the surface.[3]
Numerous men were observed in the water, but no rescue attempt was made until daylight. By then, there were no survivors among the 29 bodies floating in life jackets. Some of the bodies were wearing civilian clothes, carrying wallets with United States currency and identification cards.[4] The bodies were fingerprinted, photographed, and buried in a nighttime military ceremony at the Hampton National Cemetery.[5] U-85 lies in less than 100feet of water; the United States Navy briefly attempted to salvage her.[3] More recent investigation by sport divers has raised questions about Navy reports on the wreck.[6]
U-85 was the first U-boat loss of "Operation Drumbeat" (Paukenschlag), the offensive off the eastern seaboard of the United States in 1942.
For their actions in sinking U-85, the Navy Cross was awarded to the Ropers captain, Lieutenant Commander Hamilton W. Howe, and his commander, Destroyer Division 54 commander Commander Stanley C. Norton.[7] [8]
The hatch of U-85 is on display in the Graveyard of the Atlantic Museum; the submarine herself still serves as an attraction for divers.[9] The Labrador current influences the site and visibility can be low.[10] The majority of the debris lies within a radius of the wreck.[10] The wreck site was listed on the National Register of Historic Places in 2015.
The Enigma machine was recovered from the wreck by private divers (Jim Bunch, Roger & Rich Hunting)[11] and in 2003 the German government agreed to allow the machine to be displayed at the Graveyard of the Atlantic Museum, in Hatteras, North Carolina.[12]
