The submarine was laid down on 1 July 1942 at the Bremer Vulkan yard at Bremen-Vegesack as 'werk' 49. She was launched on 6 March 1943 and commissioned on 14 April under the command of Oberleutnant Günter Scholz.

Service history
U-284 served with the 8th U-boat Flotilla for training from April to October 1943 and operationally with the 9th flotilla from 1 November. She carried out one patrol, sinking no ships. She was a member of one wolfpack.

The boat's only patrol began with her departure from Kiel on 13 January 1944. She passed between Iceland and the Faroe Islands and into the Atlantic Ocean. She was scuttled southeast of Greenland on 21 November 1943, after sustaining sea damage. Her crew were taken off by U-629 and taken to Brest in occupied France, arriving on 5 January 1944.
