The Royal Navy's official Facebook page has just claimed that the RFA is 'part of the Royal Navy'. Wikipedia continues to claim that the RFA is part of the Naval Service, no doubt edited by MOD PR. QRRN explicitly states however that the RFA isn't part of the Royal Navy (instead describing it as a 'uniformed Merchant Marine service') and that it isn't part of the Naval Service (instead it is a 'supporting organisation...which [is] largely civilian-manned'). This is on the RN website: http://www.royalnavy.mod.uk/News-and-Events/Reference-Library/~/media/Files/Navy-PDFs/News-and-Events/Naval%20Publications/BR%202/brd2book/ch01.pdf For those who can't be bothered going through the link, these are the relevant sections: BRd 2 1-2 April 2013 CHAPTER 1 COMPOSITION OF THE NAVAL SERVICE AND JURISDICTION OF QRRN SECTION I - COMPOSITION OF THE NAVAL SERVICE 0101. Composition of the Naval Service 1. The Naval Service comprises the Royal Navy, Royal Marines, QARNNS, Reserve Forces and Naval Careers Service. The Naval Service is supported by a range of organisations (including external agencies and the Royal Fleet Auxiliary) which are largely civilian manned. The latter organisations do not form part of the Naval Service, but where they contain personnel of the Royal Navy those per sonnel individually form part of the Naval Service. They are all governed by the Admiralty Board of the Defence Council. 0105. The Royal Fleet Auxiliary (RFA) 1. The Royal Fleet Auxiliary Service (RFA) is a uniformed Merchant Marine Service accountable to the Admiralty Board through Fleet Commander. It doesn't really matter I suppose except for academic accuracy and legality, but it does seem a bit off that the RN doesn't seem to know what actually comprises the RN?
