Design
German Type IIB submarines were enlarged versions of the original Type IIs. U-17 had a displacement of 279 tonnes (275 long tons) when at the surface and 328 tonnes (323 long tons) while submerged. Officially, the standard tonnage was 250 long tons (250 t), however. The U-boat had a total length of 42.70 m (140 ft 1 in), a pressure hull length of 28.20 m (92 ft 6 in), a beam of 4.08 m (13 ft 5 in), a height of 8.60 m (28 ft 3 in), and a draught of 3.90 m (12 ft 10 in). The submarine was powered by two MWM RS 127 S four-stroke, six-cylinder diesel engines of 700 metric horsepower (510 kW; 690 shp) for cruising, two Siemens-Schuckert PG VV 322/36 double-acting electric motors producing a total of 460 metric horsepower (340 kW; 450 shp) for use while submerged. She had two shafts and two 0.85 m (3 ft) propellers. The boat was capable of operating at depths of up to 80–150 metres (260–490 ft).
The submarine had a maximum surface speed of 12 knots (22 km/h; 14 mph) and a maximum submerged speed of 7 knots (13 km/h; 8.1 mph). When submerged, the boat could operate for 35–42 nautical miles (65–78 km; 40–48 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 3,800 nautical miles (7,000 km; 4,400 mi) at 8 knots (15 km/h; 9.2 mph). U-17 was fitted with three 53.3 cm (21 in) torpedo tubes at the bow, five torpedoes or up to twelve Type A torpedo mines, and a 2 cm (0.79 in) anti-aircraft gun. The boat had a complement of twentyfive.
Service history
Its career consisted of four patrols, all served while under the 1st U-boat Flotilla where it sank three ships for a total of 1,825 gross register tons (GRT). Later in the war it served under the 22nd U-boat Flotilla as a training boat, including Oberleutnant zur See Walter Sitek as an instructor. Sitek had previously escaped imprisonment after the disabling and sinking of U-581 by HMS Westcott in February 1942. He swam 6 kilometres (3.7 mi) to Pico Island in the Azores, made his way through neutral Spain and returned to the Kriegsmarine to serve as an instructor on U-17, U-981, and U-3005.
Fate
On 5 May 1945 U-17 was scuttled at Wilhelmshaven at the western entrance of the Raeder lock.
