RMS Queen Mary 2 (also referred to as the QM2) is a transatlantic ocean liner. She is the only major ocean liner built since Queen Elizabeth 2 in 1969, the vessel she succeeded as flagship of the Cunard Line. The new ship was named Queen Mary 2 by Queen Elizabeth II in 2004 after the first RMS Queen Mary, completed in 1936. Queen Mary was in turn named after Mary of Teck, consort of King George V. With the retirement of Queen Elizabeth 2 in 2008, Queen Mary 2 is the only transatlantic ocean liner in line service between Southampton and New York, which operates for part of each year. The ship is also used for cruising, including an annual world cruise.
