Fort Victoria and Fort George combine the functions of fleet oilers and stores ships. Being large and adaptable they are equipped with an expansive flight deck, supported by hangars for three Sea King-sized helicopters.

The original plan was to build six of the class but the diminishing requirement and undoubted budget problems has meant that only two of these large and excellent ships have been constructed.

This class can embark and support both anti-submarine helicopters and troop-carrying Sea King Mk4 helicopters, which can transfer large amounts of stores to other ships.

For dual-purpose replenishment rigs are fitted, enabling transfer of fuel and stores to two ships simultaneously. The variety of tasks that these vessels can be employed upon is reflected in their complements. The ship’s company of RFA officers and ratings is supplemented by civilian Warship Support Agency staff and RN personnel who maintain the weapons.
