The Royal Australian Air Force (RAAF) is the principal air and space force of Australia, a part of the Australian Defence Force (ADF) along with the Royal Australian Navy and the Australian Army. Constitutionally, the Governor-General of Australia, is the de jure Commander-in-Chief of the Australian Defence Force. The Royal Australian Air Force is commanded by the Chief of Air Force (CAF), who is subordinate to the Chief of the Defence Force (CDF). The CAF is also directly responsible to the Minister for Defence, with the Department of Defence administering the ADF and the Air Force. Formed in March 1921, as the Australian Air Force, through the separation of the Australian Air Corps from the Army in January 1920, which in turn amalgamated the separate aerial services of both the Army and Navy. It directly continues the traditions of the Australian Flying Corps (AFC), the aviation corps of the Army that fought in the First World War and that was formed on 22 October 1912. During its history, the Royal Australian Air Force has fought in a number of major wars, including the Second World War in Europe and the Pacific, participated in the Berlin Airlift, Korean War, Malayan Emergency, Indonesia–Malaysia Confrontation, Vietnam War, and more recently, operations in East Timor, the Iraq War and subsequent intervention, and the War in Afghanistan. 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. 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 has 251 aircraft, of which 83 are combat aircraft. History Formation The RAAF traces its history back to the 1911 Imperial Conference that was held in London, where it was decided aviation should be developed within the armed forces of the British Empire. Australia implemented this decision, the first dominion to do so, by approving the establishment of the "Australian Aviation Corps". This initially consisted of the Central Flying School at Point Cook, Victoria, opening on 22 October 1912. By 1914 the corps was known as the "Australian Flying Corps". First World War Soon after the outbreak of war in 1914, the Australian Flying Corps sent aircraft to assist in capturing German colonies in what is now north-east New Guinea. However, these colonies surrendered quickly,
