The Royal Fleet Auxiliary (RFA) is a naval auxiliary fleet owned by the UK's Ministry of Defence. It is a component of His Majesty's Naval Service and provides logistical and operational support to the Royal Navy and Royal Marines. The RFA ensures the Royal Navy is supplied and supported by providing fuel and stores through replenishment at sea, transporting Royal Marines and British Army personnel, providing medical care and transporting equipment and essentials around the world. In addition the RFA acts independently providing humanitarian aid, counter piracy and counter narcotic patrols together with assisting the Royal Navy in preventing conflict and securing international trade. They are a uniformed civilian branch of the Royal Navy staffed by British merchant sailors. The RFA is one of five RN fighting arms.
RFA personnel are civilian employees of the Ministry of Defence and members of the Royal Naval Reserve and Sponsored Reserves. Although RFA personnel wear Merchant Navy rank insignia with naval uniforms, they are part of the Royal Navy. RFA vessels are commanded and crewed by these sailors, augmented with regular and reserve Royal Navy personnel who perform specialised functions such as operating and maintaining helicopters or providing hospital facilities. Royal Navy personnel are also needed to operate certain weapons, such as the Phalanx; however, other weapons (such as the DS30B 30 mm cannon) are operated by RFA personnel. The RFA counts an aviation support vessel and dock landing ships amongst its assets.
History
The RFA was first established in 1905 to provide coaling ships for the Navy in an era when the change from sail to coal-fired steam engines as the main means of propulsion meant that a network of bases around the world with coaling facilities or a fleet of ships able to supply coal were necessary for a fleet to operate away from its home country. Since the Royal Navy of that era possessed the largest network of bases around the world of any fleet, the RFA at first took a relatively minor role.
The RFA first became heavily relied upon by the Royal Navy during World War II, when the British fleet was often far from available bases, either due to the enemy capturing such bases, or, in the Pacific, because of the sheer distances involved. World War II also saw naval ships staying at sea for much longer periods than had been the case since the days of sail. Techniques of replenishment at sea (RAS) were developed. The auxiliary fleet comprised a diverse collection, with not only RFA ships, but also commissioned warships and merchantmen as well. The need for the fleet to be maintained was unambiguously demonstrated by World War II.
After 1945, the RFA became the Royal Navy's main source of support in the many conflicts that the Navy was involved in. The RFA performed important service to the Far East Fleet off Korea from 1950 until 1953, when sustained carrier operations were again mounted in Pacific waters. During the extended operations of the Konfrontasi in the 1960s, the RFA was also heavily involved. As the network of British bases overseas shrank during the end of the Empire, the Navy increasingly relied on the RFA to supply its ships during routine deployments.
The RFA played an important role in the largest naval war since 1945, the Falklands War in 1982 (where one vessel was lost and another badly damaged), and also the Gulf War, Kosovo War, Afghanistan Campaign and the 2003 invasion of Iraq.
In July 2008, the RFA was presented with a Queen's Colour, an honour unique to a civilian organisation.
Fleet
Ships in RFA service carry the ship prefix RFA, standing for Royal Fleet Auxiliary, and fly the Blue Ensign defaced with an upright gold killick anchor. All Royal Fleet Auxiliaries are built and maintained to Lloyd's Register and Department for Transport standards.
As of 2023, there are 13 ships in service with the Royal Fleet Auxiliary with a total displacement of approximately 341,000 tonnes. These figures exclude the merchant navy vessels under charter to the Ministry of Defence performing sealift and fuel provisioning roles.
Underway replenishment
The most important role provided by the RFA is replenishment at sea (RAS), therefore the mainstay of the current RFA fleet are the replenishment ships. Three classes of vessel are in service as of 2023: , the and the .
