Commodore-in-Chief is an appointment rather than a rank. Holding an appointment of commodore-in-chief does not confer upon the holder the rank of commodore or indeed any other rank. Members of the Royal Family wear the uniform of their rank and are not issued with a different uniform for the appointment.[dubious – discuss] However, Prince Edward, Duke of Edinburgh, who was appointed the Commodore-in-Chief of the Royal Fleet Auxiliary in 2006, has since appeared in the uniform of an RFA Commodore[1] followed by The Prince of Wales in 2023 when he wore the uniform of a RN Commodore.[2]
Admiral Sir Jonathon Band, First Sea Lord, said on news of the appointments: "They firmly underline the strength of the bond between the Royal Family and the Armed Forces, not least the Naval Service in which so many members of the Royal family have served with great distinction over the years."[4]
Appointees may wear the uniform and ensgina of a Royal Navy Commodore, with ensgina of the service (i.e. the Submarine Warfare Insignia), with many appointment holders opting to wear the naval uniform of their substantive or higher honorary rank.
