German submarine U-477 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

She carried out one patrol. She sank no ships.

She was sunk by a Canadian aircraft, west of Trondheim, in June 1944.[1][2]

Service history[edit]

The submarine was laid down on 17 October 1942 at the Deutsche Werke in Kiel as yard number 308, launched on 3 July 1943 and commissioned on 18 August under the command of Oberleutnant zur See Karl-Joachim Jenssen.

She served with the 5th U-boat Flotilla from 18 August 1943 for training and the 3rd flotilla from 1 June 1944 for operations.

Patrol and loss[edit]

U-432‍ '​s only patrol was preceded by a short trip from Kiel in Germany to Kristiansand in Norway. The patrol itself began with the boat's departure from Kristiansand on 15 April 1944.

On 3 June she was attacked and sunk by depth charges dropped from a Canadian Canso flying boat of No. 162 Squadron RCAF west of Trondheim.

Fifty-one men went down with U-476; there were no survivors.[1][2]
