The Supply-class fast combat support ships are 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.[1]

These are the only US Navy resupply ships able to keep up with the strike groups, but due to their cost to operate the Navy announced intentions to retire them starting in 2014.[2] The Supply-class ships are built to military combatant standards and are shock hardened.[3]

As of early 2023, USNS Rainier and USNS Bridge have been taken out of service and struck. Along with the remaining two Supply-class ships, US Navy fleets are currently supplied by Lewis and Clark-class dry cargo ships as well as Henry J. Kaiser-class and John Lewis-class replenishment oilers.

The AOE 6 class ships, which are built to a MIL-SPEC combatant standards design, and have survivability features (i.e., shock, blast, etc.) equivalent to other ships in the CVBG, significantly extends the endurance of the CVBG for combat operations.
