List of Royal Air Force air chief marshals

The following is a list of Royal Air Force air chief marshals. The rank of air chief marshal is a four-star officer rank and currently the highest rank to which RAF officers may be promoted to in a professional capacity. 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 Vice-Chief of the Defence Staff (the only tri-service 4-star post currently occupied by an air chief marshal).

The rank was first used in 1922 when Sir Hugh Trenchard the then Chief of the Air Staff was promoted. Up until the mid-1930s there was usually only one RAF officer in the rank of air chief marshal. During World War II, with the great expansion of the RAF, the number of air chief marshals active at any one time rose to six by the end of the War. This number of air chief marshals was to remain approximately constant throughout the Cold War but after the British defence cuts of the mid-1990s there were only two dedicated 4-star RAF posts, namely the AOC-in-C, Strike Command and the Chief of the Air Staff. In 2007 with the reduction to a single command (Air Command) the RAF initially retained two air chief marshal posts (the AOC-in-C, Air Command and the Chief of the Air Staff) but in 2012 the post of AOC-in-C, Air Command was subsumed within the responsibilities of the Chief of the Air Staff leaving only a single dedicated RAF air chief marshal post.
