Design

Type U 5s had an overall length of 57.30 m (188 ft 0 in) The boats' beam was 5.60 m (18 ft 4 in), the draught was 3.55 m (11 ft 8 in). The boats displaced 505 tonnes (497 long tons) when surfaced and 636 t (626 long tons) when submerged.^[1][2]

Type U 5s were fitted with two Körting 6-cylinder and two 8-cylinder two-stroke paraffin engines with a total of 900 metric horsepower (662 kW; 888 bhp) for use on the surface and two SSW double-acting electric motors with a total of 760 kW (1,033 PS; 1,019 shp) for underwater use. These engines powered two shafts, which gave the boats a top surface speed of 13.4 knots (24.8 km/h; 15.4 mph), and 10.2 knots (18.9 km/h; 11.7 mph) when submerged. Cruising range was 3,300 nautical miles (6,100 km; 3,800 mi) at 9 knots (17 km/h; 10 mph) on the surface and 55 nautical miles (102 km; 63 mi) at 5 knots (9.3 km/h; 5.8 mph) submerged.^[1][2] Diving depth was 30 m (98 ft 5 in).^[2]

The U-boats were armed with four 45 cm (18 in) torpedo tubes, two fitted in the bow and two in the stern, and carried six torpedoes. The boats' complement was 4 officers and 24 enlisted.^[3][2]
