The Myanmar Air Force (, ), known until 1989 as the Burmese Air Force, is the aerial branch of Myanmar's armed forces, the Tatmadaw. The primary mission of the Myanmar Air Force since its inception has been to provide transport, logistical, and close air support to the Myanmar Army in counter-insurgency operations. It is mainly used in internal conflicts in Myanmar, and, on a smaller scale, in relief missions, especially after the deadly Cyclone Nargis of May 2008.
