Aquila was an Italian aircraft carrier converted from the transatlantic passenger liner SS Roma. During World War II, Work on Aquila began in late 1941 at the Ansaldo shipyard in Genoa and continued for the next two years. With the signing of the Italian armistice on 8 September 1943, however, all work was halted and the vessel remained unfinished. She was captured by the National Republican Navy of the Italian Social Republic and the German occupation forces in 1943, but in 1945 she was partially sunk by a commando attack of Mariassalto, an Italian royalist assault unit of the Co-Belligerent Navy of the Kingdom of Italy, made up by members of the former Decima Flottiglia MAS. Aquila was eventually refloated and scrapped in 1952.

Ansaldo was one of Italy's oldest and most important engineering companies, existing for 140 years from 1853 to 1993.
