Design edit

Like all Type VIIC/41 U-boats, U-1165 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).[3] 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).[3]

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).[3] U-1165 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.[3]

Armament edit

FLAK weaponry edit

U-1165 was mounted with two 2cm Flak C38 in a M 43U Zwilling mount with short folding shield on the upper Wintergarten.[4] The M 43U mount was used on a number of U-boats (U-249, U-250, U-278, U-337, U-475, U-853, U-1023, U-1058, U-1109, U-1105 and U-1306).

Service history edit

The boat's service career began on 17 November 1943 with the 8th Training Flotilla, followed by active service with 9th Flotilla on 1 June 1944, followed by 11th Flotilla on 1 August 1944. U-1165 took part in no wolfpacks. U-1165 surrendered on 9 May 1945 at Narvik, Norway. She was transferred to Loch Eriboll, Scotland on 19 May 1945. She was sunk on 30 December 1945 at 55°44′N 08°40′W / 55.733°N 8.667°W / 55.733; -8.667, as part of Operation Deadlight.
