The Fort Rosalie or Fort class is a class of fleet replenishment vessel of the British Royal Fleet Auxiliary. These ships are designed to replenish Royal Navy taskgroups with all kinds of armaments and victualling stores while under way; unlike the bigger Fort Victoria class they supply dry stores but not fuel. RFA Fort Rosalie was originally known as Fort Grange, but was renamed in 2000 to avoid confusion with the new Fort Victoria class replenishment oiler RFA Fort George.
