The rank of Admiral is the highest in the Royal Navy apart from that of Admiral of the Fleet. It is superior to two other ranks of Admiral: Vice Admiral and Rear Admiral.

Jane Austen had two brothers who served in the Royal Navy and were involved in the French Revolutionary Wars and the Napoleonic Wars. Her younger brother, Sir Charles John Austen (1779-1852), rose to the rank of Rear Admiral, while her older brother, Sir Francis William Austen (1774-1865), achieved the highest rank of all, Admiral of the Fleet.
