Admiral of the fleet or fleet admiral (Russian: Адмирал флота, romanized: Admiral flota) is the highest rank of the Russian Navy. It is the equivalent of the Soviet naval rank of fleet admiral, and is roughly the equivalent to a four-star rank of other nations. In the present day, general of the army is its equivalent in the Russian Ground Forces, Aerospace Forces, Airborne Forces, Strategic Rocket Forces, and Federal Security Service. Marshal of the Russian Federation is the only superior rank in the Russian Armed Forces, and it has no naval equivalent.
