The Ausonia (2) was built in 1921 by Armstrong Whitworth & Co in Newcastle, as the third of Cunard's six post-World War I "A Liners". She was the sister ship of the S/S Andania (2), S/S Antonia and S/S Aurania (3). On August 31, 1922, she departed on her maiden voyage, Liverpool - Montreal. In 1927 she was refitted for the new cabin-, tourist- and third-class configuration. In 1939 the Ausonia was requisitioned as an armed merchant cruiser, and in 1942 she was purchased by the Navy and then converted into a heavy repair ship. In 1965 she was scrapped in Spain.
