SS President Taft was launched as one of the "state" ships, Buckeye State, completed by the United States Shipping Board as cargo passenger ships after originally being laid down as troop transports. Buckeye State had been laid down as Bertrice but was converted and renamed before launching. Originally assigned to the Matson Navigation Company as the Shipping Board's agent, the ship was later renamed President Taft and assigned to Pacific Mail Steamship Company for operation. In 1925 the Shipping Board sold the ship to Dollar Steamship Company. President Taft was operated by Dollar and then its successor American President Lines until requisitioned by the War Department on 17 June 1941.
