German submarine U-423 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

She carried out one patrol. She did not sink or damage any ships.

She was sunk by a Norwegian aircraft northwest of the Faroe Islands in June 1944.[3][4]

Service history[edit]

The submarine was laid down on 16 March 1942 at the Danziger Werft (yard) at Danzig (now Gdansk), as 'werk' 124, launched on 7 November and commissioned on 3 March under the command of Oberleutnant zur See Joachim Methner.

She served with the 8th U-boat Flotilla from 3 March 1943 until her loss.

Patrol and loss[edit]

The boat's only patrol commenced with her departure from Kiel on 9 June 1944. On the 17th, she was sunk northeast of the Faroe Islands by depth charges dropped from a Norwegian PBY Catalina flying boat of No. 333 Squadron RAF.

Fifty-three men went down with the U-boat; there were no survivors.
