SS Roma was an ocean liner built for the Italian shipping company Navigazione Generale Italiana of Genoa by Ansaldo shipyard in Sestri Ponente.

She was taken over by the National Republican Navy of the Italian Social Republic and German occupation forces in 1943, but was partially sunk in 1945 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.

Navigazione Generale Italiana ordered two new 30,000 gross register tons transatlantic ocean liners from Ansaldo shipyard.

Steam for the turbines was provided by 9 double-ended and 4 single-ended boilers; all in all, the ship was able to boast a maximum speed of 22 knots (41 km/h; 25 mph).

Fearing that the Germans could seize her and scuttle her as a blockship at the entrance of Genoa's harbour, just as had happened a few months earlier to Roma 's sister ship Augustus, then already become the aircraft carrier Sparviero, the Mariassalto commando unit, made up by members of the former Decima Flottiglia MAS, launched a manned torpedo attack on the night of the 18 and 19 of April 1945, partially sinking the Aquila.
