Stülcken Sohn yard at Hamburg, launched on 14 December 1942, and commissioned on 17 March 1943 under the command of Oberleutnant zur See Helmut Röttger.

Service history
On the first and final patrol, U-715 was spotted north-east of Faeroe on 13 June 1944 by Canso T of No. 162 Squadron RCAF and attacked with depth charges while snorkeling at periscope depth. Heavily damaged, the U-boat surfaced and returned fire, managing to down the Canadian aircraft before sinking in position. This was the first occasion when a submerged U-boat was detected and attacked. Of the crew of 52, only 16 survived.
