German submarine U-1008 was a Type VIIC/41 U-boat of Nazi Germany's Kriegsmarine during World War II.
She was ordered on 23 March 1942, and was laid down on 12 February 1943, at Blohm & Voss, Hamburg, as yard number 208. She was launched on 8 December 1943, and commissioned under the command of Oberleutnant zur See Diether Todenhagen on 1 February 1944.
German Type VIIC/41 submarines were preceded by the heavier Type VIIC submarines. U-1008 had a displacement of when at the surface and while submerged. She had a total length of , a pressure hull length of , an overall beam of , a height of , and a draught of . The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of for use while surfaced, two BBC GG UB 720/8 double-acting electric motors producing a total of for use while submerged. She had two shafts and two 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-1008 was fitted with five torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes or 26 TMA or TMB Naval mines, one SK C/35 naval gun, (220 rounds), one Flak M42 and two C/30 anti-aircraft guns. The boat had a complement of between forty-four and fifty-two.
U-1008 did not participate in any war patrols.
On 5 May 1945, U-1008 was in the Kattegat, , when she was attacked with depth charges by a British B-24 Liberator of the 224th/T piloted by F/Lt F.S. Murphy, W/Cdr M.A. Ensor. The B-24 was given credit for sinking but the attack only resulted in minor damage to U-1008. It would seem though, through conflicting postwar accounts, that the boat was scuttled the next day at north of Hjelm Island with all 44 of her crew surviving.
