Sunken Warships: Secrets from the Deep Season 2

Formerly light cruiser USS Phoenix but sold to Argentinia after World War II, the renamed General Belgrano was controversially torpedoed during the Falklands Conflict.

When launched, HMS Barham was one of the most powerful battleships afloat but her distinguished career was brought to an end in 1941 by a torpedo from a German U-boat.
