air marshal

Air marshal (Air Mshl or AM) is an air-officer rank which originated within the Royal Air Force. The rank is used by the air forces of many countries which have historical British influence, including many Commonwealth nations. The rank is usually equivalent to a vice admiral or a lieutenant general. Air marshal is immediately senior to the rank of air vice-marshal and immediately subordinate to the rank of air chief marshal. Officers in the rank of air marshal typically hold very senior appointments such as commander-in-chief of an air force or a large air force formation. Officers in the ranks of air chief marshal and air vice-marshal are also referred to generically as air marshals. Occasionally, air force officers of marshal rank are considered to be air marshals. Royal Air Force use and history Origins Prior to the adoption of RAF-specific rank titles in 1919, it was suggested that the RAF might use the Royal Navy's officer ranks, with the word "air" inserted before the naval rank title. For example, the rank that later became air marshal would have been air vice-admiral. The Admiralty objected to any use of their rank titles, including this modified form, and so an alternative proposal was put forward: air-officer ranks would be based on the term "ardian", which was derived from a combination of the Gaelic words for "chief" and "bird", with the term "second ardian" or "wing ardian" being used specifically for the rank equivalent to a vice-admiral and lieutenant-general. However, air marshal was preferred and has been used since its adoption in August 1919. Sir Hugh Trenchard, the incumbent Chief of the Air Staff when the rank was introduced, became the first air marshal on 11 August 1919.
