Royal Australian Air Force [SEP] Introduction
The Royal Australian Air Force (RAAF), formed in March 1921, is the aerial warfare branch of the Australian Defence Force (ADF). It operates the majority of the ADF's fixed wing aircraft, although both the Australian Army and Royal Australian Navy also operate aircraft in various roles. It directly continues the traditions of the Australian Flying Corps (AFC), formed on 22 October 1912. The RAAF provides support across a spectrum of operations such as air superiority, precision strikes, intelligence, surveillance and reconnaissance, air mobility, space surveillance, and humanitarian support. The RAAF took part in many of the 20th century's major conflicts.
