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.[1] 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).[1]

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).[1] 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.[1]

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.
