Boston Sea Rovers - U-1105 Black Panther

U-1105 is a modified Type VII-C German submarine commissioned in the Kriegsmarine. Nicknamed “Black Panther”, U-1105 was one of only 13 submarines outfitted with an experimental rubber skin designed to evade Allied SONAR. During U-1105’s only war patrol, she torpedoed the British frigate HMS Redmill. U-1105 surrendered at the end of World War Two and was a sought after war prize for study of its unique rubber skin. After trials by the British Royal Navy, U-1105 was transferred to the US Navy which used U-1105 for explosive testing. A 250-pound depth charge sent U-1105 to the bottom of the Potomac River in 1949 for the sixth and final time. U-1105 remained lost to history until she was re-discovered in 1985. U-1105 is the most accessible U-boat off the US East Coast.
