German submarine U-216

German submarine U-216 was a Type VIID mine-laying U-boat of the Nazi German Kriegsmarine during World War II. She was one of six U-boats of her kind, equipped with special vertical tubes that launched the mines. Her keel was laid down 1 January 1941 by Germaniawerft in Kiel as 'werk' 648. She was launched on 23 October 1941 and commissioned on 15 December 1941 with Oberleutnant Karl-Otto Schultz in command.

Service history
U-216 conducted only one patrol, sailing from Kiel on 29 August 1942. On 25 September, U-216 fired four torpedos at the British Coast Lines Limited ship, Boston. After three hits, the survivors from the ship were picked up by HMS Veteran (D72) which was sunk the next day by GS U-404. On 20 October, the U-boat was depth charged by a British Liberator aircraft and sunk southwest of Ireland in position 48.21N, 19.25W with all hands lost.
