German submarine U-164 was a Type IXC U-boat of Nazi Germany's Kriegsmarine built for service during World War II. The keel for this boat was laid down on 20 June 1940 at the Deutsche Schiff- und Maschinenbau AG, Bremen yard as yard number 703. She was launched on 1 May 1941 and commissioned on 28 November 1941 under the command of Korvettenkapitän Otto Fechner.
The U-boat's service began with training as part of the 4th U-boat Flotilla. She then moved to the 10th flotilla on 1 August 1942 for operations. She sank three ships, totalling 8,133 gross register tons (GRT).
She was sunk by an American aircraft in January 1943.
German Type IXC submarines were slightly larger than the original Type IXBs. U-164 had a displacement of 1,120 tonnes (1,100 long tons) when at the surface and 1,232 tonnes (1,213 long tons) while submerged. The U-boat had a total length of 76.76 m (251 ft 10 in), a pressure hull length of 58.75 m (192 ft 9 in), a beam of 6.76 m (22 ft 2 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.70 m (15 ft 5 in). The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of 4,400 metric horsepower (3,240 kW; 4,340 shp) for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1,000 metric horsepower (740 kW; 990 shp) for use while submerged. She had two shafts and two 1.92 m (6 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).
The submarine had a maximum surface speed of 18.3 knots (33.9 km/h; 21.1 mph) and a maximum submerged speed of 7.3 knots (13.5 km/h; 8.4 mph). When submerged, the boat could operate for 63 nautical miles (117 km; 72 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 13,450 nautical miles (24,910 km; 15,480 mi) at 10 knots (19 km/h; 12 mph). U-164 was fitted with six 53.3 cm (21 in) torpedo tubes (four fitted at the bow and two at the stern), 22 torpedoes, one 10.5 cm (4.13 in) SK C/32 naval gun, 180 rounds, and a 3.7 cm (1.5 in) SK C/30 as well as a 2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of forty-eight.
The submarine's first patrol took her from Kiel on 18 July 1942, across the North Sea and into the Atlantic Ocean through the gap between Iceland and the Faroe Islands. She sank Stad Amsterdam on 25 August in the eastern Caribbean. The first torpedoes hit, except they were duds, probably fired from too close-in; but a coup de grǎce caused the ship to sink stern-first. The boat also sank John A. Holloway northwest of Curaçao. U-164 arrived at Lorient, in occupied France, on 7 October. She would be based at this Atlantic port for the rest of her brief career.
