German submarine U-528

German submarine U-528 was a Type IXC U-boat of the Nazi German Kriegsmarine during World War II.

She was laid down at the Deutsche Werft (yard) in Hamburg as 'werk' 343 on 10 November 1941, launched on 1 July 1942 and commissioned on 16 September with Kapitänleutnant Karl-Heinz Fuchs in command.

U-528 began her service career with training as part of the 4th U-boat Flotilla from 16 September 1942. She was re-assigned to the 10th flotilla for operations on 1 April 1943.

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

She was sunk by a British aircraft and a British warship southwest of Ireland, in May 1943.

Patrol and loss
The boat departed Kiel on 15 April 1943, moved through the North Sea, negotiated the 'gap' between Iceland and the Faroe Islands and entered the Atlantic Ocean. There, she was intercepted by the escorts of Convoy ON (S) 5 and damaged. She was sunk on her way to the French Atlantic bases.

U-528 was 'destroyed' on 11 May 1943 southwest of Ireland by depth charges dropped from a Handley Page Halifax of No. 58 Squadron RAF and the British sloop HMS Fleetwood.

Eleven men went down with the U-boat; there were 45 survivors.
