German submarine U-184

German submarine U-184 was a Type IXC/40 U-boat of the Nazi German Kriegsmarine built for service during World War II.

She was ordered	on 15 August 1940 and was laid down on 10 June 1941 at AG Weser, Bremen, becoming 'werk 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.

Service history
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 mi 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-184's loss remains an unsolved mystery.

Previously recorded fate
U-184 was thought to have been sunk by depth charges from the Norwegian corvette HNOMS Potentilla, but in a post-war assessment this attack was later found to have been against GS U-264, and had inflicted only minor damage.
