Eddy-class tanker

The Eddy-class coastal tankers were Royal Fleet Auxiliary Replenishment oilers built from 1951–1953 tasked with transporting and providing fuel and other liquids to Royal Navy vessels and stations around the world. There were originally ten ships planned in the class, although the final two were cancelled in 1952. Originally designed to act as fleet attendant oilers, in this role the ships were obsolete almost as soon as they were built due to the increasing prevalence of replenishment at sea, and their role was refocused to coastal transport duties.
