Throughout the history of the RAF there have been 140 RAF officers promoted to air chief marshal and at present two RAF officers hold the rank in an active capacity, namely the Chief of the Air Staff (the only dedicated RAF 4-star post) and the Chief of the Defence Staff (the only tri-service 4-star post currently occupied by an air chief marshal).

Richard Williams, regarded as the "father" of the Royal Australian Air Force, was the service's first member to obtain air-officer rank on being promoted to air commodore (one-star rank) in 1927; he went on to become the first air vice marshal (1935) and air marshal (1940).
