Fort Victoria-class replenishment oiler

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. As such they are designated auxiliary oiler replenisher (AOR). They are tasked with providing ammunition, fuel, food and other supplies to Royal Navy vessels around the world. There are two ships in the class, Fort Victoria and Fort George, the latter being taken out of service in 2011 due to major design flaws in the original design.

History
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. The Fort class ships were therefore expected to defend both themselves and the Type 23 frigates with the Sea Wolf vertical launch surface-to-air missile (SAM).

The lessons of the Falklands War and the end of the Cold War led to a re-evaluation of this plan. The Type 23 emerged as a much more potent, multi-role vessel each carrying the Sea Wolf missile and the requirement for the Fort class was reduced from six to two.

Fort Victoria was built by Harland and Wolff and Fort George by Swan Hunter and the ships entered service in 1994 and 1993 respectively.
