German submarine U-14 was a Type IIB U-boat of Nazi Germany's Kriegsmarine during World War II. It served with 3rd U-boat Flotilla from 18 January 1936 to 31 October 1939. U-14 completed six wartime patrols and sank nine ships totalling 12,344 GRT.
German Type IIB submarines were enlarged versions of the original Type IIs. U-14 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-14 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.
Early in the war, on 3 September 1939, U-14 attacked a Polish submarine and claimed to have sunk it. In reality the Polish submarine, ORP Sęp, was not damaged as the torpedo launched by U-14 exploded prematurely.
After serving on six operational patrols, U-14 was used as a training boat and transferred to U-boat training flotillas, serving with the 23rd and 24th U-boat Flotillas until the end of the war. Despite the high casualties suffered by the Unterseebootwaffen (German submarine arm), U-14 suffered no known casualties during the war.
U-14 was scuttled on 2 May 1945 at Wilhelmshaven.
