Auxiliary oiler replenisher

A replenishment oiler is a naval auxiliary ship with fuel tanks and dry stores capability, which can replenish other ships underway. The US Navy hull classification symbol for this type of ship is AOR. Classes include the Wichita-class ships of the US Navy, the Soviet/Russian Boris Chilikin type, and the Canadian Protecteur class. They are slower and carry fewer dry stores than Fast Combat Support Ship (AOE) ships.
