Design edit

German Type VIIC/41 submarines were preceded by the heavier Type VIIC submarines. U-1003 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-1003 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 edit

U-1003 participated in two war patrol which resulted in no ships damaged or sunk.[2]

On 7 February 1944, during U-1003's trials, a crewman fell overboard and died while transferring to an outpost boat, near Hela on the Baltic Sea.[2]

U-1003 had Schnorchel underwater-breathing apparatus fitted out sometime before October 1944.[2]

U-1003 departed Bergen, Norway on 9 February, on her second, and last, war patrol. On 20 March 1945, thirty days into her patrol, her snorkel was spotted by HMCS New Glasgow off her port bow. New Glasgow had started preparations for a depth charge attack when she herself was damaged just below the bridge upon colliding with U-1003. Fourteen Allied ships, from Escort Groups C-4, C-25, and C-26, began a massive search for the heavily damaged U-boat but U-1003 managed to elude them. She then sat on the bottom for another 48 hours for repairs, however, on 23 March, the severe damage to the boat forced her crew to scuttle her off the coast of Ireland. Of the 48 men onboard U-1003, 33 were picked up by HMCS Thetford Mines, two of which died and were buried at sea. Oblt.z.S. Werner Strübing and the remaining 14 crew members were lost.[2]

The wreck now lies at 55°38′N 7°26′W / 55.633°N 7.433°W / 55.633; -7.433.
