German submarine U-1006

German submarine U-1006 was a Type VIIC/41 U-boat of Nazi Germany's Kriegsmarine during World War II.

She was ordered on 14 October 1941, and was laid down on 30 January 1943 at Blohm & Voss, Hamburg, as yard number 206. She was launched on 17 November 1943 and commissioned under the command of Oberleutnant zur See Horst Voigt on 11 January 1944.

Design
German Type VIIC/41 submarines were preceded by the heavier Type VIIC submarines. U-1006 had a displacement of 769 t when at the surface and 871 t while submerged. She had a total length of 67.10 m, a pressure hull length of 50.50 m, an overall beam of 6.20 m, a height of 9.60 m, and a draught of 4.74 m. The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2800 to 3200 PS for use while surfaced, two BBC GG UB 720/8 double-acting electric motors producing a total of 750 PS for use while submerged. She had two shafts and two 1.23 m propellers. The boat was capable of operating at depths of up to 230 m.

The submarine had a maximum surface speed of 17.7 kn and a maximum submerged speed of 7.6 kn. When submerged, the boat could operate for 80 nmi at 4 kn; when surfaced, she could travel 8500 nmi at 10 kn. U-1006 was fitted with five 53.3 cm torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes or 26 TMA or TMB Naval mines, one 8.8 cm SK C/35 naval gun, 220 rounds, and an anti-aircraft gun. The boat had a complement of between forty-four and fifty-two.

Service history
U-1006 participated in one war patrol which resulted in no ships damaged or sunk.

U-1006 had Schnorchel underwater-breathing apparatus fitted out sometime before October 1944.

On 9 October 1944, U-1006 left Bergen, Norway, for what would be her first, and only, war patrol. Eight days into her patrol, south-east of Faeroe Islands, in the North Atlantic, she was detected by HMCS Annan (K404). Annan proceeded to drop depth charges on U-1006 even though they did not initially believe the contact was a U-boat. Annan then returned to the 6th EG where HMCS Loch Achanalt (K424) also made contact with U-1006 and ordered Annan to attack again. The first depth charge attack had badly damaged U-1006 and forced her to surface. U-1006 was able to fire a torpedo at Annan as she approached, but it detonated prematurely causing no damage. After Annan illuminated the area she opened fire on U-1006, which was able to return fire for a short time. U-1006's 44 remaining crewmen abandoned ship and she was sunk by two depth charges, six men had been killed in the attack.

The wreck now lies at 60.98333°N, -4.81667°W.
