The German torpedo boat T27 was one of fifteen Type 39 torpedo boats built for the Kriegsmarine (German Navy) during World War II. Completed in early 1943, the boat was transferred to France in August. T27 helped to lay a minefield in the English Channel the following month, and later escorted a blockade runner through the Bay of Biscay. She participated in the Battle of Sept-Îles in October and played a minor role in the Battle of the Bay of Biscay. The boat was lightly damaged during the action of 26 April 1944 off the coast of Brittany and ran aground during the subsequent two days later. Her wreck was destroyed shortly afterwards by the British.
