SS Leviathan 1924
The second of three sister ships built for Germany’s Hamburg America Line for their transatlantic passenger service, she sailed as Vaterland for less than a year before her early career was halted by the start of World War I. In 1917, she was seized by the U.S. government and renamed Leviathan. She would become known by this name for the majority of her career, both as a troopship during World War I and later as the flagship of the United States Lines.
