Admiral (Royal Navy)

Admiral is a senior rank of the Royal Navy, which equates to the NATO rank code OF-9, outranked only by the rank of admiral of the fleet. Royal Navy officers holding the ranks of rear admiral, vice admiral and admiral of the fleet are sometimes considered generically to be admirals. The rank of admiral is currently the highest rank to which a serving officer in the Royal Navy can be promoted, admiral of the fleet being in abeyance except for honorary promotions of retired officers and members of the Royal Family.
