Allies of World War I
SS "Main" was an ocean liner of the "Rhein" class of North German Lloyd. She was in service on the route from Bremen to Baltimore from her 1900 launch until seized by the Allies of World War I in 1914, and was involved in the 1900 Hoboken Docks Fire. Unlike her sister ships "Neckar" and "Rhein", she never entered service for the United States Navy.
