A troopship is a ship used to carry soldiers, either in peacetime or wartime. Troopships were often drafted from commercial shipping fleets, and were unable to land troops directly on shore, typically loading and unloading at a seaport or onto smaller vessels, either tenders or barges.

Nicknamed the "Grey Ghost", RMS Queen Mary holds the all-time record for most troops on one passage, 15,740 on a late July 1943 run from the U.S. to Europe.

RMS Queen Mary is a retired British ocean liner that sailed primarily on the North Atlantic Ocean from 1936 to 1967 for the Cunard Line and was built by John Brown & Company in Clydebank, Scotland. Queen Mary, along with RMSÂ Queen Elizabeth, was built as part of Cunard's planned two-ship weekly express service between Southampton, Cherbourg and New York. The two ships were a British response to the express superliners built by German, Italian and French companies in the late 1920s and early 1930s.
