Air commodore (
Air Cdre in the RAF and
IAF;
AIRCDRE in the
RNZAF and
RAAF; formerly
A/C in the
RCAF) is a
one-star rank and the most junior of the
air-officer ranks which originated in and continues to be used by the
Royal Air Force. The rank is also used by the air forces of many
countries which have historical British influence such as
Bangladesh, and it is sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure. The name of the rank is always the full phrase and is never shortened to "Commodore".
