She was ordered on 15 August 1940 and was laid down on 10 June 1941 at DeSchiMAG AG Weser, Bremen, becoming yard number 1024. She was launched on 21 February 1942 and commissioned under her first and only commander Kapitänleutnant Günther Dangschat on 29 May. After a period of training with the 4th U-boat Flotilla, she joined the 2nd U-boat Flotilla for operational service on 1 November 1942.
German Type IXC/40 submarines were slightly larger than the original Type IXCs. U-184 had a displacement of 1,144 tonnes (1,126 long tons) when at the surface and 1,257 tonnes (1,237 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 6.86 m (22 ft 6 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.67 m (15 ft 4 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 shaft horsepower (1,010 PS; 750 kW) 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 13,850 nautical miles (25,650 km; 15,940 mi) at 10 knots (19 km/h; 12 mph). U-184 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) as well as a 2 cm (0.79 in) anti-aircraft gun. The boat had a complement of forty-eight.
On her first and only combat patrol she departed Bergen in Norway on 9 November 1942 and entered the north Atlantic via the gap between Iceland and the Faroe Islands. She sank a single ship, the British merchant vessel SS Widestone about 500 nmi (930 km; 580 mi) southeast of Cape Farewell (Greenland) on 17 November 1942. There were no survivors.
Previously recorded fate
U-184 was thought to have been sunk by depth charges from the Norwegian corvette Potentilla, but in a post-war assessment this attack was later found to have been against U-264, and had inflicted only minor damage.
