Queen Mary 2

RMS Queen Mary 2 (QM2) is a British ocean liner which has been the flagship of Cunard since April 2004 and, as of 2026, remains the only ship built and used for service as an ocean liner still in active service. Queen Mary 2 sails regular transatlantic crossings between Southampton and New York City, in addition to short cruises and an annual world voyage. She was designed by a team of British naval architects led by Stephen Payne, and was constructed in France by Chantiers de l'Atlantique. At the time of her construction, Queen Mary 2 was the longest, at 1,131.99 ft (345.03 m), and largest, with a gross tonnage of 148,528 GT, passenger ship ever built. She no longer holds these records after the construction of Royal Caribbean International's 154,407 GT Freedom of the Seas (a cruise ship) in April 2006, but remains the largest ocean liner ever built. Queen Mary 2 was intended for some crossings of the Atlantic Ocean; the final construction cost was approximately $300,000 per berth. The cost was increased by the high quality of materials; having been designed as an ocean liner, 40% more steel was required for a cruise liner than for a standard cruise ship. Queen Mary 2 has a maximum speed of just over 30 knots (56 km/h; 35 mph) and a cruising speed of 26 knots (48 km/h; 30 mph), which is faster than a contemporary cruise ship. Instead of the common diesel-electric configuration, Queen Mary 2 uses integrated electric propulsion to achieve her top speed. Diesel engines, augmented by gas turbines, are used to generate electricity for electric motors for propulsion and for on-board use. Queen Mary 2's facilities include fifteen restaurants and bars, four swimming pools (originally five), a casino, the largest ballroom on a ship in service,...
