The U-boat was ordered in January 1941 and laid down at the DESCHIMAG AG Weser shipyard on 17 March 1942. Assigned yard number 1056, she was launched on 7 December of that year. Commissioned on 17 April 1943 under the command of Korvettenkapitän Klaus Ewerth (Crew 25), who had previously commanded U-26. U-850 served with the 4th U-boat Flotilla until the end of October when she transferred to the 12th U-boat Flotilla for front-line service. U-850 left Kiel on 18 November 1943 destined for the Indian Ocean in order to join Monsoon Group, she was, however, spotted and attacked by US aircraft from USS Bogue west of Madeira on 20 December ans successfully attacked.
On 20 December 1943, while en route to the Indian Ocean, U-850 was spotted by aircraft of Squadron VC-19. The first aircraft, an Avenger piloted by Lieutenant W.A. La Fleur, attacked the U-boat with depth charges which missed their target. After La Fleur reported the sighting via radio, two Wildcats accompanied by two more Avengers - T18 and T19 - arrived on the scene. While the Wildcats strafed U-850, T19, piloted by Ensign G.C. Goodwin, made another attack with depth charges which hit their target. The U-boat tried to evade by crash diving, but T18, piloted by Lieutenant H.G. Bradshaw, dropped two FIDO torpedoes, which both hit the U-boat on the starboard side. USS George E. Badger and Du Pont later recovered some dead bodies, body parts, and pieces of wreakage. There were no survivors.
U-850 did not sink or damage any ships while in service.
