The German torpedo boat T20 was one of nine Type 37 torpedo boats built for the Kriegsmarine (German Navy) during World War II. Completed in mid-1942, she was transferred to Norway in March 1943 for escort duties. The ship returned to Germany in October and was assigned to the Torpedo School. T20 returned to active duty a year later and supported German forces operating in the Baltic Sea. She was then assigned escort duties in the Skagerrak around the beginning of 1945, which included covering minelaying missions. The ship was allocated to the British after the war, but she was transferred to France in 1946. Unused by the French Navy, she was stricken from the Navy List in 1951 and subsequently scrapped.
