The fourth Mercury (SP‑3012) was built as SS Barbarossa by Blohm und Voss, Hamburg, Germany, in 1896, and operated by the North German Lloyd Line until she took refuge in Hoboken, N.J., at the outbreak of World War I. She was seized when the United States entered the war 6 April 1917; damage inflicted by her crew prior to seizure was repaired; and she was commissioned 3 August 1917, Comdr. H. L. Brinser in command. Shortly after commissioning she was renamed Mercury.
Mercury got underway for her first transatlantic troop-ferrying mission 4 January 1918. Before the armistice, 11 November 1918, she had completed seven voyages to France, carrying over 18,000 passengers. After the armistice, she reversed the flow of troops, making eight crossings to return more than 20,000 to the United States. After completing her last crossing as a U.S. Navy ship 19 September 1919, she decommissioned and was turned over to the Army Transport Service 27 September 1919.
