German submarine U-1107 was a Type VIIC/41 U-boat built for Nazi Germany’s Kriegsmarine for service during World War II.
She was laid down on 20 August 1943 by Nordseewerke, Emden as yard number 229, launched on 30 June 1944 and commissioned on 8 August 1944 under Oberleutnant zur See Fritz Parduhn.

Like all Type VIIC/41 U-boats, U-1107 had a displacement of 759 tonnes (747 long tons) when at the surface and 860 tonnes (850 long tons) while submerged. She had a total length of 67.23 m (220 ft 7 in), a pressure hull length of 50.50 m (165 ft 8 in), a beam of 6.20 m (20 ft 4 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two Germaniawerft F46 supercharged six-cylinder four-stroke 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) and 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. The boat was capable of operating at a depth of 250 metres (820 ft).

The submarine had a maximum surface speed of 17.7 knots (32.8 km/h; 20.4 mph) and a 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-1107 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. Its complement was between forty-four and sixty.

Service history[edit]

The boat’s career began with training at 8th U-boat Flotilla on 8 August 1944, followed by active service on 16 February 1945 as part of the 11th Flotilla for the remainder of her service. In one patrol she sank two merchant ships, for a total of 15,209 gross register tons (GRT).

Fate[edit]

U-1107 was sunk on 30 April 1945 in the Bay of Biscay west of Brest, in position 48°12′N 05°42′W / 48.200°N 5.700°W / 48.200; -5.700 by a homing torpedo from a US Navy Liberator of VP-103. All hands lost[1]

Previously recorded fate[edit]

U-1107 was sunk on 30 April 1945 in the Bay of Biscay in position 48°00′N 06°30′W / 48.000°N 6.500°W / 48.000; -6.500, by bombs from US Navy Catalina ‘R’ of VPB-63, flown by Lt F.G. Lake. The aircraft was flying a MAD Rover patrol, and dropped 24 bombs when the craft was detected.[4] 37 crew were killed with an unknown number of survivors.
