The SS Cape Jacob is a steam turbine-driven ship, first launched as the SS California. It was to be used by the Maritime Administration, and was delivered in 1962 and put under contract to the States Steamship Company. The ship was later transferred to the Military Sealift Command, and put into reserve status temporarily. It was then transferred to active duty as a prepositioning ship.
