U 550


U 550 was a type IXC/40 uboat laid down at Deutche Werft in Hamburg in October 1942. She was launched in May 1943, and was commissioned two months later, entering service in 4. Unterseeboot Flotille for training. In February 1944 she was transferred to 10 .Flotille in Lorient in France. U 550 did one war patrol and manage to torpedo and sink the tanker Pan Pennsylvania outside Nantucuket. She was soon after forced to surface by depth charges from the American destroyer escorts USS Gandy, USS Joyce and USS Peterson 16. April 1944. After she surfaced she was sunk by gun fire and only twelve men from U 550 survived the engagement. The wreck was found in 2012 south of Nantucket and rest today in open waters on a depth of 100 meter.
