The SS Rex was an Italian ocean liner launched in 1931. It held the westbound Blue Riband between 1933 and 1935. Originally built for the Navigazione Generale Italiana (NGI) as the SS Guglielmo Marconi, its state-ordered merger with the Lloyd Sabaudo line meant that the ship sailed for the newly created Italia Flotta Riunite (Italian Line). On May 12, 1938, in a demonstration of U.S. air power, three YB-17 bombers of the U.S. Army Air Corps intercepted the Rex 620 nautical miles (1,100 km) at sea in a highly publicized event.
