[Image:Flag of the United Kingdom.svg|thumbnail|right|100px|The flag of an Admiral of the Fleet is the
Union Flag, and is in 1:2 rather than the 2:3 of other admirals' flags.]]Admiral of the Fleet is a rank of the British
Royal Navy and other navies, the equivalent of
Fleet Admiral in the
United States Navy.The rank evolved from the ancient sailing days of the Royal Navy. The fleet was divided into three divisions and each designated a
colour, that of Red, White, or Blue. Each coloured division was assigned an Admiral, who in turn had command over a
Vice-Admiral and a
Rear Admiral. The Admiral of the Fleet, therefore, commanded the Admirals of the various divisions and thus, the entirety of the Fleet.
