German submarine U-184 was a Type IXC/40 U-boat of Nazi Germany's Kriegsmarine built for service during World War II.
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.[1] 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.[1]
German Type IXC/40 submarines were slightly larger than the original Type IXCs. U-184 had a displacement of 1144t when at the surface and 1257t while submerged. The U-boat had a total length of 76.76m (251.84feet), a pressure hull length of 58.75m (192.75feet), a beam of 6.86m (22.51feet), a height of 9.6m (31.5feet), and a draught of 4.67m (15.32feet). The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of 4400PS for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1000shp for use while submerged. She had two shafts and two 1.92abbr=onNaNabbr=on propellers. The boat was capable of operating at depths of up to .
The submarine had a maximum surface speed of and a maximum submerged speed of . When submerged, the boat could operate for at ; when surfaced, she could travel at . U-184 was fitted with six 53.30NaN0 torpedo tubes (four fitted at the bow and two at the stern), 22 torpedoes, one 10.52NaN2 SK C/32 naval gun, 180 rounds, and a 3.7sp=usNaNsp=us SK C/30 as well as a 2sp=usNaNsp=us C/30 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 Widestone[2] about 500nmi southeast of Cape Farewell (Greenland) on 17 November 1942. There were no survivors.
On 21 November she was listed as missing with all 50 hands east of Newfoundland, in approximate position 49°N -45°W.
U-184s loss remains an unsolved mystery.[1] It is possible that she was sunk by a Canadian plane or warship as a result of the Battle of the St. Lawrence.
U-184 was thought to have been sunk by depth charges from the Norwegian corvette, but in a post-war assessment this attack was later found to have been against, and had inflicted only minor damage.[3]
