RMS Aquitania was a British ocean liner of the 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 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-funneled ocean liner. Shortly after Aquitania entered service, World War I broke out, during which she was first converted into an auxiliary cruiser before being used as a troop transport and a hospital ship, notably as part of the Dardanelles Campaign. Aquitania ended her career as the longest-serving Cunard vessel, a record which stood for six years until overtaken by RMS Scythia's service record of 37 years. In 2004 Aquitania's service record was pushed into third place when Queen Elizabeth 2 became the longest-serving Cunard vessel.
