The German torpedo boat T21 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. T21 returned to active duty in May 1944 and supported German forces operating in the Baltic Sea. The boat began a major refit in December which had not been completed when the war ended in May 1945. She was allocated to the United States after the war, but was only used to dispose of gas munitions by scuttling her in deep water in 1946.
