The Royal Australian Air Force (RAAF), formed 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, and humanitarian support.

The RAAF took part in many of the 20th century's major conflicts. During the early years of the Second World War a number of RAAF bomber, fighter, reconnaissance and other squadrons served in Britain, and with the Desert Air Force located in North Africa and the Mediterranean. From 1942, a large number of RAAF units were formed in Australia, and fought in South West Pacific Area. Thousands of Australians also served with other Commonwealth air forces in Europe, including during the bomber offensive against Germany. By the time the war ended, a total of 216,900 men and women served in the RAAF, of whom 10,562 were killed in action.
