The Naval Command senior appointments are: The Commandant General Royal Marines was previously a major-general's post and charged with leading amphibious warfare operations.

Locations Historically, the Royal Navy divided the planet into a number of Stations, the number and boundaries of which changed over time. The former stations of the Royal Navy included the East Indies Station (1744-1831); East Indies and China Station (1832-1865); East Indies Station (1865-1913); Egypt and East Indies Station (1913-1918); East Indies Station (1918-1941). In response to increased Japanese threats, the separate East Indies Station was merged with the China Station in December 1941, to form the Eastern Fleet. Later the Eastern Fleet became the East Indies Fleet. In 1952, after the Second World War ended, the East Indies Fleet became the Far East Fleet. The Royal Navy currently operates from three bases in the United Kingdom where commissioned ships are based; Portsmouth, Clyde and Devonport, Plymouth—Devonport is the largest operational naval base in the UK and Western Europe. Each base hosts a flotilla command under a commodore, responsible for the provision of operational capability using the ships and submarines within the flotilla. 3 Commando Brigade Royal Marines is similarly commanded by a brigadier and based in Plymouth. Historically, the Royal Navy maintained Royal Navy Dockyards around the world. Dockyards of the Royal Navy are harbours where ships are overhauled and refitted. Only four are operating today; at Devonport, Faslane, Rosyth and at Portsmouth. A Naval Base Review was undertaken in 2006 and early 2007, the outcome being announced by Secretary of State for Defence, Des Browne, confirming that all would remain however some reductions in manpower were anticipated. The academy where initial training for future Royal Navy officers takes place is Britannia Royal Naval College, located on
