The Commander-in-Chief Fleet (CINCFLEET) was the admiral responsible for the operations of the ships, submarines and aircraft of the British Royal Navy from 1971 until April 2012. The post was subordinate to the First Sea Lord, the professional head of the Naval Service. In its last years, as the Navy shrank, more administrative responsibilities were added.
In April 2012, the post was abolished, its rank downgraded from admiral to three-star vice admiral, and re-designated Fleet Commander and Deputy Chief of Naval Staff.
