Admiral Sir Mark Stanhope, is a retired Royal Navy officer. After serving as a submarine commander, he commanded a frigate and then commanded an aircraft carrier on operational patrol off Sierra Leone. He went on to be Deputy Supreme Allied Commander Transformation and then Commander-in-Chief Fleet. He served as First Sea Lord and Chief of the Naval staff, the professional head of the Royal Navy, from July 2009 to April 2013. In this role he advised the British Government on the deployment of naval forces during operations around Libya. He was succeeded by Admiral Sir George Zambellas in April 2013.

An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighters, strike aircraft, helicopters, and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, these aircraft have not landed on a carrier. By its diplomatic and tactical power, its mobility, its autonomy and the variety of its means, the aircraft carrier is often the centerpiece of modern combat fleets. Tactically or even strategically, it replaced the battleship in the role of flagship of a fleet. One of its great advantages is that, by sailing in international waters, it does not interfere with any territorial sovereignty and thus obviates the need for overflight authorizations from third-party countries, reduces the times and transit distances of aircraft and therefore significantly increases the time of availability on the combat zone.
