The 13th U-boat Flotilla was a World War II U-boat unit of Nazi Germany's Kriegsmarine stationed in Trondheim, Norway. The emblem of the unit was a cross with a Viking ship in the middle.
U-995 is the only surviving Type VIIC/41 submarine; after service in the Kriegsmarine during World War II, she served as HNoMS Kaura in the Royal Norwegian Navy and is now a museum ship in Germany.
