The submarine was laid down on 25 February 1942 at the Friedrich Krupp Germaniawerft yard at Kiel as yard number 665, launched on 4 November and commissioned on 19 December under the command of Oberleutnant zur See Goske von Möllendorf.
After training with the 5th U-boat Flotilla at Kiel, U-235 was transferred to the 22nd flotilla on 29 October 1943, following her sinking in May by US bombs in Kiel. She had been raised, repaired and returned to service. She was reassigned to the 31st U-boat Flotilla on 2 April 1945, less than two weeks before her second sinking.
U-235 was sunk in error in April 1945 in the Kattegat by a German torpedo boat.
U-235 was heading to Norway with U-1272 when they encountered a small German convoy accompanied by the torpedo boat T-17. All vessels had not been warned of the others' presence. But the convoy had been warned that a British submarine was in the area. U-1272 dived deep and out of trouble, but U-235 surfaced, possibly to identify herself and then as if changing her mind, also dived. T-17 attacked, dropping depth charges. Any celebration on T-17 was abruptly stilled when amongst the wreckage appearing were bodies in Kriegsmarine uniform. Forty-six men died; there were no survivors.
