Sacramento-class fast combat support ship

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.

On top of that the Underway Replenishment Groups of that time were slow and unwieldy.

After experimenting with this "replenishment oiler" concept with the German war prize Dithmarschen (placed in service as USS Conecuh (AOR-110)), the US Navy's solution to these problems was to create a multi-product station ship, which resulted in the construction of the Sacramento class.

The AOEs were also designed to be much faster than previous auxiliaries at 26 knots, giving them the ability to operate in company with a carrier battle group rather than in a separate, slower replenishment group.

To fulfill the same role in the less demanding Anti-Submarine Support Aircraft Carrier (CVS) groups, the navy built the similar, but smaller and slower, Wichita-class AORs.
