German submarine U-428 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

She carried out no patrols. She did not sink or damage any ships.

She was scuttled in northern Germany in May 1945. The wreck was broken up in 1946.[1]

Service history[edit]

The submarine was laid down on 13 August 1942 at the Danziger Werft (yard) at Danzig (now Gdansk), as yard number 129, launched on 11 March 1943 and commissioned on 26 June under the command of Capitano di Corvetta Athos Fraternale.

She served with the 8th U-boat Flotilla from 26 June 1943 and the 23rd flotilla from 1 October. She was reassigned to the 31st flotilla on 1 March 1945.

The U-boat was named S-1 after being acquired by the Italian Navy in exchange for some transport ships. She returned to Germany after the Italian surrender where she was renamed U-428.

Fate[edit]

The submarine was scuttled in the Nordsee/Ostsee canal (Kiel canal) near Audorf on 3 May 1945. The wreck was broken up in 1946.
