Type U 17 was a class of U-boats built during World War I by the Kaiserliche Marine.

Design

[edit]

Type U 17s had an overall length of 62.35 m (204 ft 7 in) The boats' beam was 6.00 m (19 ft 8 in), the draught was 3.40 m (11 ft 2 in), with a total height of 7.30 m (23 ft 11 in). The boats displaced 564 tonnes (555 long tons) when surfaced and 691 t (680 long tons) when submerged.[1]

Type U 17s were fitted with two Körting 8-cylinder two-stroke paraffin engines with a total of 1,400 metric horsepower (1,030 kW; 1,381 bhp) for use on the surface and two AEG double-acting electric motors with a total of 820 kW (1,115 PS; 1,100 shp) for underwater use. These engines powered two shafts, which gave the boats a top surface speed of 14.9 knots (27.6 km/h; 17.1 mph), and 9.5 knots (17.6 km/h; 10.9 mph) when submerged. Cruising range was 6,700 nautical miles (12,400 km; 7,700 mi) at 8 knots (15 km/h; 9.2 mph) on the surface and 75 nautical miles (139 km; 86 mi) at 5 knots (9.3 km/h; 5.8 mph) submerged.[1] Diving depth was 50 m (164 ft 1 in).

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 25 enlisted.[1]
