German submarine U-187

German submarine U-187 was a Type IXC/40 U-boat of the Nazi German Kriegsmarine built for service during World War II. Her keel was laid down on 6 August 1941 by AG Weser in Bremen as 'werk' 1027. She was launched on 16 March 1942 and commissioned on 23 July with Kapitänleutnant Ralph Münnich in command.

The U-boat's service began with training as part of the 4th U-boat Flotilla. She then moved to the 10th flotilla on 1 January 1943 for operations.

She was sunk by two British destroyers in February 1943.

Patrol and loss
U-186's patrol took her from Kiel on 12 January 1943, across the North Sea and into the Atlantic Ocean through the 'gap' between Iceland and the Faroe Islands.

She was sunk in mid-Atlantic by depth charges dropped by the British destroyers HMS Vimy and Beverley. Nine men died; there were 45 survivors.
