RFA Derwentdale (A221) was a Dale-class Mobile Bulk Tanker of the Royal Fleet Auxiliary (RFA), the naval auxiliary fleet of the United Kingdom. She was on a long-term charter from 1967 to support the Royal Navy east of Suez and was at the time the largest ship in the RFA fleet. Derwentdale had no replenishment at sea (RAS) equipment and was later classed as a Mobile Reserve Tanker.[2]
