The Queen Mary and Manhattan: a magnificent pairing of might and modernity. The towering New York skyline makes the ship’s stature all the more impressive, as indeed she was: her overall length was 1,019 feet and she measured 118 feet high. The Queen Mary made her maiden voyage on May 27, 1936 from Southampton to New York. During World War II, she and the Queen Elizabeth were the largest and fastest troopships, often carrying as many as 15,000 men in a single voyage. After the war, she resumed passenger service until she was retired in 1967.
