German submarine U-1002

German submarine U-1002 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 4 January 1943 at Blohm & Voss, Hamburg, as yard number 202. She was launched on 6 October 1943 and commissioned under the command of Oberleutnant zur See Albrecht Schubart on 30 November 1943.

Design
German Type VIIC/41 submarines were preceded by the heavier Type VIIC submarines. U-1002 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-1002 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-1002 participated in only one war patrol which resulted in no ships damaged or sunk.

On 9 May 1945, U-1002 surrendered at Bergen, Norway and was transferred to Lisahally on 30 May 1945, where she would wait nearly seven months for her final fate. Of the 156 U-boats that eventually surrendered to the Allied forces at the end of the war, U-1002 was one of 116 selected to take part in Operation Deadlight. U-1002 was towed out but sank on 13 December 1945, by unknown causes, becoming one of the 56 U-boats that sank before reaching the scuttling areas.

The wreck now lies at 56.16667°N, -10.08333°W.
