The Fort Victoria or Fort II class is a class of replenishment oiler of the Royal Fleet Auxiliary, a role that combines the missions of a tanker and stores supply ship.

They are tasked with providing ammunition, fuel, food and other supplies to Royal Navy vessels around the world.

Six ships were initially planned to supply the Type 23 frigates in their North Atlantic anti-submarine role.

The Type 23 was at the time planned to be a low cost, lightly armed vessel and the Fort-class ships were therefore expected to defend themselves with the Sea Wolf vertical launch surface-to-air missile (SAM).

The lessons of the Falklands War meant the Type 23 developed as a much more potent, multi-role vessel carrying the Sea Wolf missile.
