German submarine U-1104 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 29 June 1943, at Nordseewerke, Emden, as yard number 226. She was launched on 7 December 1943, and commissioned under the command of Oberleutnant zur See Rüdiger Perleberg on 15 March 1944.

Design

German Type VIIC/41 submarines were preceded by the heavier Type VIIC submarines. U-1104 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 SSW GU 343/38-8 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).

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-1104 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.

Service history

On 9 May 1945, U-1104 surrendered at Bergen, Norway and was later transferred to Loch Ryan, Scotland on 30 May 1945. Of the 156 U-boats that eventually surrendered to the Allied forces at the end of the war, U-1104 was one of 116 selected to take part in Operation Deadlight. U-1104 was towed out and sank on 1 December 1945 by naval gunfire.

The wreck now lies at 56°10′N 10°05′W / 56.167°N 10.083°W / 56.167; -10.083.
