History of the Royal Australian Air Force

The Royal Australian Air Force (RAAF) traces its history back to the Imperial Conference held in London in 1911, where it was decided aviation should be developed within the Armed Forces of the British Empire. Australia implemented this decision, the only country to do so, by approving the establishment of the Central Flying School at Point Cook, Victoria in 1912.

The Australian Flying Corps (AFC) was formed within the First Australian Imperial Force (AIF), and earned a most creditable reputation in both Palestine and France during World War I. The Australian Flying Corps remained part of the Australian Army until 1919, when it was disbanded along with the AIF. Although the Central Flying School continued to operate at Point Cook, military flying virtually ceased until 1920, when the Australian Air Corps was formed.

The Australian Air Force was formed on 31 March 1921. King George V approved the prefix "Royal" in June 1921 and became effective on the 31 August 1921. The RAAF then became the second Royal air arm to be formed in the British Commonwealth, following the British Royal Air Force.

World War I

Soon after the outbreak of World War I in 1914, the Australian Flying Corps sent aircraft to assist in capturing German colonies in what is now north-west New Guinea. These colonies surrendered quickly however, before the planes were even unpacked. The first operational flights did not occur until May 27, 1915, when the Mesopotamian Half Flight was called upon to assist the Indian Army in protecting British oil interests in what is now Iraq. The Corps later saw action in Egypt, Palestine and on the Western Front throughout the remainder of World War I. By the end of the war, four squadrons had seen active service.

World War II

In 1939, just after the start of World War II, Australia joined the Empire Air Training Scheme, under which flight crews received basic training in Australia before travelling to Canada for advanced training. A total of 19 RAAF bomber, fighter, reconnaissance and other squadrons served initially in Britain, and/or with the Desert Air Force, in North Africa and the Mediterranean.

With British manufacturing targeted by the "Luftwaffe", the Australian government created the Department of Aircraft Production (DAP; later known as the Government Aircraft Factory) to supply Commonwealth air forces and the RAAF was eventually provided with large numbers of locally-built versions of British designs like the Beaufort torpedo bomber.

In the European Theatre of World War II, RAAF personnel were especially notable in RAF Bomber Command: although they represented only two percent of all RAAF personnel during the war, they accounted for 23% of the total number killed in action. This statistic is further illustrated by the fact that No. 460 Squadron RAAF, mostly flying Avro Lancasters, had an official establishment of about 200 aircrew and yet had 1,018 combat deaths. The squadron was therefore effectively wiped out five times over.

The beginning of the Pacific War — and the rapid advance of Japanese forces — threatened the Australian mainland for the first time. The RAAF was quite unprepared for the emergency, and initially had negligible forces available for service in the Pacific. The devastating air raids on Darwin on February 19 1942 drove the point home. Some RAAF squadrons were transferred from the northern hemisphere — although a substantial number remained there until the end of the war. Shortages of fighter and ground attack planes led to the acquisition of US-built P-40 Kittyhawks and the rapid design and manufacture of the first Australian fighter, the CAC Boomerang. RAAF Kittyhawks came to play a crucial role in the New Guinea and Solomon Islands campaigns, especially in operations like the Battle of Milne Bay.

In the Battle of the Bismarck Sea, imported Bristol Beaufighters proved to be highly effective ground attack and maritime strike aircraft. Beaufighters were later made locally by the DAP. Although it was much bigger than Japanese fighters, the Beaufighter had the speed to outrun them.

The RAAF's heavy bomber force predominantly comprised 287 B-24 Liberators, which could bomb Japanese targets as far away as Borneo and the Philippines from airfields in Australia and New Guinea.

By late 1945, the RAAF had received or ordered about 500 P-51 Mustangs, for fighter/ground attack purposes. The Commonwealth Aircraft Corporation initially assembled US-made Mustangs, but later manufactured most of those used. The RAAF's main operational formation, the First Tactical Air Force, comprised more than 18,000 personnel and 20 squadrons; it had taken part in the Philippines and Borneo campaigns and was scheduled to participate in the invasion of the Japanese mainland, Operation Downfall. So too were the RAAF bomber squadrons in Europe, as part of the proposed Tiger Force. However, the war was brought to a sudden end by the US nuclear attacks on Japan. As a result of the Empire Air Training Scheme, about 20,000 Australian personnel had served with other Commonwealth air forces in Europe during World War II. A total of 216,900 men and women served in the RAAF, of whom 11,061 were killed in action.

Post-war service

In the Korean War, Mustangs from No. 77 Squadron (77 Sqn), stationed in Japan with the British Commonwealth Occupation Force, were among the first United Nations aircraft to be deployed, in ground support, combat air patrol, and escort missions. When the UN planes were confronted by MiG-15 jet fighters, 77 Sqn acquired Gloster Meteors, which enabled some success against the Soviet pilots flying for North Korea. However the MiGs were superior aircraft and the Meteors were relegated to ground support missions, as the North Koreans gained experience. The air force also operated transport aircraft during the conflict.

During the Vietnam War, from 1966-72, the RAAF contributed squadrons of Caribou STOL transport aircraft (No. 35 Squadron), UH-1 Iroquois helicopters (No. 9 Squadron) and English Electric Canberra bombers (No. 2 Squadron). The Canberras flew a large number of bombing sorties, and two were lost. One went missing during a bombing raid, and neither the crew nor the aircraft has ever been located. The other was shot down by a surface to air missile, although both crew were rescued. RAAF transport aircraft also supported anti-communist ground forces. The UH-1 helicopters were used in many roles including Dustoff (medical evacuation) and Bushranger Gunships for armed support.

Military airlifts were conducted for a number of purposes in the intervening decades, such as the peacekeeping operations in East Timor from 1999. Australia's combat aircraft were not used again in anger until the Iraq War in 2003, when F/A-18s from No. 75 Squadron operated in the escort and ground attack roles.
