German submarine U-1001 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 31 December 1942, at Blohm & Voss, Hamburg, as yard number 201. She was launched on 6 October 1943, and commissioned under the command of Kapitänleutnant Ernst-Ulrich Blaudow on 18 November 1943.[2]

Design

German Type VIIC/41 submarines were preceded by the heavier Type VIIC submarines. U-1001 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged. She had a total length of 67.10 m (220 ft 2 in), a pressure hull length of 50.50 m (165 ft 8 in), an overall beam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two Germaniawerft F46 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 metric horsepower (550 kW; 740 shp) for use while submerged. She had two shafts and two 1.23 m (4 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).[3]

The submarine had a maximum surface speed of 17.7 knots (32.8 km/h; 20.4 mph) and a maximum submerged speed of 7.6 knots (14.1 km/h; 8.7 mph). When submerged, the boat could operate for 80 nautical miles (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 10 knots (19 km/h; 12 mph). U-1001 was fitted with five 53.3 cm (21 in) 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 (3.46 in) SK C/35 naval gun, (220 rounds), one 3.7 cm (1.5 in) Flak M42 and two 2 cm (0.79 in) C/30 anti-aircraft guns. The boat had a complement of between forty-four and fifty-two.[3]

Service history

U-1001 participated in six war patrols. None of these resulted in any ships damaged or sunk.[2]

On 21 September, during her third war patrol, U-1001 laid 15 TMB near Porkkala, on the Baltic Sea. The next day, 22 Sep 1944, U-1001 rescued 13 shipwrecked German soldiers from the Baltic and landed them later on 2 October, at Libau.[4]

On 29 October 1944, during her fourth war patrol, U-1001 transferred two medical cases from U-958 and U-475 in the Baltic.[5]

U-1001 had Schnorchel underwater-breathing apparatus fitted out in February 1945.[2]

On 8 April 1945, 29 days out of Kristiansand, on her sixth war patrol, she was located by the British frigates HMS Fitzroy and HMS Byron. U-1001 was sunk by depth charges in the North Atlantic south-west of Land's End, killing all forty-six of her crew.[2]

The wreck now lies at 49°19′N 10°23′W / 49.317°N 10.383°W / 49.317; -10.383.
