The Rover class is a British ship class of five small fleet tankers, active from 1970 to 2017 with the Royal Fleet Auxiliary (RFA), the naval auxiliary fleet of the United Kingdom. One remains in service, having been sold to Indonesia; the rest have been scrapped or are awaiting disposal, including the one sold to Portugal. They are tasked with the replenishment at sea (RAS) of naval warships with fuel oils and with limited supplies of other naval stores. For RAS tasking, they can refuel a vessel on either beam and a third trailing astern and have a large flight deck to allow vertical replenishment with helicopters.
