RMS Aquitania was a British ocean liner of Cunard Line in service from 1914 to 1950. She was designed by Leonard Peskett and built by John Brown & Company in Clydebank, Scotland. She was launched on 21 April 1913^[4] and sailed on her maiden voyage from Liverpool to New York on 30 May 1914. Aquitania was the third in Cunard Line's grand trio of express liners, preceded by RMS Mauretania and RMS Lusitania, and was the last surviving four-funnelled ocean liner.^[5] Shortly after entering service, World War I
broke out, during which she was first transformed into an auxiliary
cruiser before being transformed into a troop transport and a hospital
ship, notably as part of the Dardanelles Campaign.


Returned to transatlantic passenger service in 1920, she served alongside the Mauretania and the Berengaria. Widely considered during this period of time as one of the most attractive ships, Aquitania earned the nickname "the Ship Beautiful" from her passengers.^[3] Her popularity allowed her service to be continued after the merger of Cunard Line with White Star Line in 1934. The company planned to retire her and replace her with RMS Queen Elizabeth in 1940.


However, the outbreak of World War II allowed her to remain in
service for ten more years. During the war and until 1947, she served as
a troop transport. She was used in particular to bring home Canadian
soldiers from Europe. After the war, she transported migrants to Canada
before the Board of Trade found her unfit for further commercial
service. Aquitania was retired from service in 1949 and was scrapped the following year. Having served as a passenger ship for 36 years, Aquitania became the second longest serving Cunard vessel after RMS Scythia (37 years). That record stood until 2004 when Queen Elizabeth 2 became the longest serving Cunard vessel.
