Launched in 1906, SS "Havana" was a passenger steamer for the Ward Line on the New York–Havana route from 1907 to 1917. Before being purchased by the Navy, the ship briefly served as United States Army transport ship USAT "Havana" and was in the first U.S. convoy of ships to sail for France during World War I. In her Navy career, "Comfort" made three transatlantic voyages, bringing home over 1,100 men from European ports. "Comfort" was placed in reserve in September 1919, decommissioned in 1921, and sold in April 1925.
