USS Phoenix (CL-46), was a light cruiser of the Brooklyn-class cruiser family. She was the third Phoenix of the United States Navy. After World War II the ship was transferred to Argentina in 1951 and was ultimately renamed General Belgrano in 1956. General Belgrano was sunk during the Falklands War in 1982 by the British nuclear-powered submarine HMS Conqueror, the only ship to have been sunk in combat by a nuclear-powered submarine during wartime.
