German submarine U-977 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine that attempted to escape to Argentina after the end of World War II in Europe, but was forced to surrender on 17 August 1945. Like U-530, the Allies questioned the crew about whether they had sank the Brazilian cruiser Bahia or helped high-ranking Nazis escape.
