RFA Olmeda (A124) was an "fast fleet tanker" of the Royal Fleet Auxiliary (RFA) the naval auxiliary fleet of the United Kingdom. She was designed by the builders to meet specific requirements and be capable of maintaining “fleet speed” (defined as sustained steaming at 20 knots). When she entered service she was one of the largest and fastest ships in the RFA Fleet. Initially named Oleander, she was renamed after two years in operation.
The second of her class, Olmeda came into service in late 1965 as Oleander. As with her sister ships, Olmeda's early service was routine. However, in 1967, the ship had to be renamed from Oleander to Olmeda to avoid confusion with .
The ship had the capability to supply fuel and other liquid cargo to vessels using four pairs of replenishment rigs which were located between the forward and aft superstructures. She was able to carry four types of fuels: Furnace Fuel Oil, Diesel, Avcat and Mogas. Limited supplies of lubricating oils, fresh water and dry stores could also be carried. She could operate Westland Wessex or Westland Sea King helicopters, or other helicopters of similar size, from a hangar and flight deck at the stern.
