 Sacramento-class fast combat support ship

The "Sacramento"-class fast combat support ships were a class of four United States Navy supply ships used to refuel, rearm, and restock ships in the United States Navy in both the Atlantic and Pacific Oceans.The idea of combining the capabilities of a fleet oiler (AO), ammunition ship (AE), and refrigerated stores ship (AF) had been conceived during the Second World War by Admiral Arleigh Burke, later Chief of Naval Operations, who sought to create a single ship that would perform the functions of three vessels while simultaneously integrating into a carrier battle group.
