Design[edit]

German Type U 93 submarines were preceded by the shorter Type U 87 submarines. U-165 had a displacement of 821 tonnes (808 long tons) when at the surface and 1,002 tonnes (986 long tons) while submerged.[1] She had a total length of 71.55 metres (234 ft 9 in), a pressure hull length of 56.05 m (183 ft 11 in), a beam of 6.30 m (20 ft 8 in), a height of 8.25 m (27 ft 1 in), and a draught of 3.88 m (12 ft 9 in). The submarine was powered by two 2,400 metric horsepower (1,800 kW; 2,400 shp) engines for use while surfaced, and two 1,230 metric horsepower (900 kW; 1,210 shp) engines for use while submerged. She had two propeller shafts and two 1.70 m (5 ft 7 in) propellers. She was capable of operating at depths of up to 50 metres (160 ft).[1]

The submarine had a maximum surface speed of 16.2 knots (30.0 km/h; 18.6 mph) and a maximum submerged speed of 8.2 knots (15.2 km/h; 9.4 mph).[1] When submerged, she could operate for 50 nautical miles (93 km; 58 mi) at 5 knots (9.3 km/h; 5.8 mph); when surfaced, she could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 8 knots (15 km/h; 9.2 mph). U-165 was fitted with six 50 centimetres (20 in) torpedo tubes (four at the bow and two at the stern), twelve to sixteen torpedoes, and one 10.5 cm (4.1 in) SK L/45 deck gun. She had a complement of thirty-six (thirty-two crew members and four officers).[1]
