Admiral of the Fleet is a five-star naval officer rank and the highest rank of the Royal Navy formally established in 1688. The five-star NATO rank code is OF-10, equivalent to a field marshal in the British Army or a Marshal of the Royal Air Force. Other than honorary appointments, no new admirals of the fleet have been named since 1995, and no honorary appointments have been made since 2014. History The origins of the rank can be traced back to John de Beauchamp, 1st Baron Beauchamp de Warwick, who was appointed 'Admiral of the King's Southern, Northern and Western Fleets' on 18 July 1360. The appointment gave the command of the English navy to one person for the first time; this evolved into the post of Admiral of the Fleet.

Appointments were for life, remunerated via a £5 daily stipend and an annual allowance of £1,014 for the hiring and maintenance of servants. It was intended that only one officer would hold the rank at any time, with their presence aboard any naval vessel to be denoted by the flying of the Royal Standard from the main mast. The ranks of Admiral of the Fleet and Admiral of the Red were formally separated from 1805, with an announcement in the London Gazette that "His Majesty [has] been pleased to order the Rank of Admirals of the Red to be restored" in His Majesty's Navy..." as a separate role. The same Gazette promoted 22 men to that rank. From the nineteenth century onward there were also occasional variations to the previous requirement that only one Admiral of Fleet
