German submarine U-422 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

She carried out one patrol. She was a member of one wolfpack. She did not sink or damage any ships.

She was sunk by an American aircraft north of the Azores in October 1943.[1][3]

Service history[edit]

The submarine was laid down on 11 February 1942 at the Danziger Werft (yard) at Danzig (now Gdansk), as yard number 123, launched on 10 October and commissioned on 10 February under the command of Oberleutnant zur See Wolfgang Poeschel.

She served with the 8th U-boat Flotilla from 10 February 1943 and the 1st flotilla from 1 August 1943.

Patrol and loss[edit]

The boat's only patrol was preceded by a trip from Kiel in Germany to Bergen in Norway. U-422 then left Bergen on 8 September 1943 and headed for the Atlantic Ocean via the gap between Iceland and the Faroe Islands. U-422 was depth charged and strafed by what was reported as a Handley Page Halifax on the 23rd. Three men were wounded, two of them seriously. Medical assistance could only be given when the submarine rendezvoused with U-460, a 'milch cow' supply vessel.

On 4 October, she was attacked and sunk by a FIDO homing torpedo dropped by an American TBM Avenger which was accompanied by a F4F Wildcat. Both aircraft had come from the escort carrier USS Card.

Forty-nine men went down with the U-boat; there were no survivors.


U-422 took part in one wolfpack, namely.
