The Royal Australian Air Force (RAAF) stands today as one of the world’s most advanced air forces, having evolved from humble beginnings with just 21 officers and 128 other ranks in 1921 to become a cutting-edge military service operating sophisticated fifth-generation aircraft. Created as the world’s second independent air force after Britain’s Royal Air Force, the RAAF has participated in nearly every major conflict of the 20th and 21st centuries while continuously adapting to changing strategic circumstances, technological developments, and alliance relationships. Its story reflects both Australia’s commitment to collective security and its pursuit of increasingly independent defense capabilities within the context of its key alliances.
Origins and foundation: The Australian Flying Corps
Australia’s military aviation began before the RAAF’s official formation, with the establishment of the Central Flying School at Point Cook, Victoria in 1912 following the 1911 Imperial Conference in London. The Australian Flying Corps (AFC) was formed as a part of the Australian Army, becoming the first dominion air arm in the British Empire.
During World War I, the AFC expanded to four combat squadrons serving in the Middle East and Western Front, along with four training squadrons in the United Kingdom. These units established a credible reputation, with AFC fighter squadrons credited with 384 enemy aircraft destroyed. The AFC’s wartime service included:
- No. 1 Squadron: Deployed to the Middle East and served in Palestine
- No. 2 Squadron: Served on the Western Front
- No. 3 Squadron: Performed corps reconnaissance roles on the Western Front
- No. 4 Squadron: Combat operations on the Western Front
The AFC was disbanded with the rest of the Australian Imperial Force after WWI, and military flying virtually ceased until the interim Australian Air Corps was formed in January 1920.
Birth of an independent service (1921-1939)
On March 31, 1921, the Australian Air Force was officially established as an independent service. Air Marshal Sir Richard Williams, widely regarded as the “father of the RAAF,” deliberately chose this date rather than April 1st (the RAF’s formation anniversary) “to prevent nasty people referring to us as ‘April Fools’.” King George V approved the prefix “Royal” in June 1921, which became effective on August 13, 1921.
The newly formed RAAF faced the paradox of having more aircraft than personnel – 153 aircraft but just 21 officers and 128 other ranks. Most of these aircraft came from Britain’s “Imperial Gift” of 128 surplus World War I aircraft. The interwar period presented significant challenges:
- Severe budget constraints during the Great Depression
- Institutional threats to the RAAF’s independence from Army and Navy interests
- Equipment shortages with British manufacturers often unable to meet requirements
Despite these limitations, the RAAF established key bases beyond Point Cook, including RAAF Base Laverton (1925) and RAAF Base Richmond (1925). The service conducted valuable non-combat operations including:
- Aerial surveys and mapping of remote areas
- Regular meteorological flights
- Bush fire patrols in Victoria
- Search and rescue operations
- The first aerial circumnavigation of Australia (1924)
By the outbreak of WWII in September 1939, the RAAF had expanded to about 3,500 personnel with 246 aircraft organized in 12 squadrons, with plans for 6 more. This modest force would soon undergo an unprecedented transformation.
Crucible of war: WWII expansion (1939-1945)
World War II dramatically transformed the RAAF from a small, ill-equipped force into the world’s fourth-largest Allied air force. At the outbreak of war in 1939, the RAAF had no modern combat aircraft suitable for operations against advanced enemy forces. By war’s end in 1945, approximately 216,900 men and women had served, with the force operating about 6,000 aircraft in 50 squadrons.
The Empire Air Training Scheme played a pivotal role in this expansion:
- Australia committed to train 28,000 aircrew over three years
- The RAAF established numerous specialized training schools
- By 1945, over 37,000 Australian airmen had been trained
- Australian aircrew supplied approximately 9% of all aircrew who fought for the RAF in European and Mediterranean theaters
European and Mediterranean Operations
In Europe and the Mediterranean, 17 RAAF squadrons served under the Article XV agreement of the Empire Air Training Scheme. Many Australians also served in RAF squadrons. Notable contributions included:
- No. 460 Squadron: Australia’s most famous bomber squadron, suffering 1,018 combat deaths while operating Wellingtons and later Lancasters
- Bomber Command operations: Between 3,486 and 4,050 Australians were killed, accounting for nearly 20% of all Australian combat deaths in WWII
- North Africa and Middle East campaigns against German and Italian forces
- Malta defense with RAAF personnel participating in the island’s defense
Pacific Theater
The Japanese advance in 1941-42 directly threatened Australia, finding the RAAF unprepared. After the fall of Singapore on February 15, 1942, and the bombing of Darwin on February 19, 1942, the RAAF reorganized for homeland defense and operations in the Southwest Pacific:
- Malaya and Singapore defense: RAAF units equipped with inadequate aircraft like the Brewster Buffalo suffered heavy losses
- Darwin air raids: The first attacks on Australian soil, with raids continuing until November 1943
- Battle of Milne Bay (August-September 1942): RAAF Kittyhawks played a crucial role in the first land defeat of Japanese forces
- Battle of the Bismarck Sea (March 2-4, 1943): RAAF Beaufighters helped destroy an entire Japanese convoy
- Counter-offensive operations across New Guinea, Dutch East Indies, Philippines, and Borneo
The RAAF adapted quickly, acquiring aircraft like the Curtiss P-40 Kittyhawk and developing the indigenous CAC Boomerang fighter. Australia also expanded domestic aircraft production through the Commonwealth Aircraft Corporation (established 1936) and the Department of Aircraft Production (established 1941).
The RAAF’s wartime expansion was accompanied by tremendous sacrifice, with approximately 10,562 personnel killed in action or dying while in service. The Victoria Cross was awarded to two RAAF members: Flight Lieutenant William Newton and Warrant Officer Rawdon Hume Middleton, both posthumously.
Cold War and regional conflicts (1945-1972)
The immediate post-war period saw rapid demobilization, with the RAAF shrinking dramatically from its wartime peak. Nevertheless, it remained larger than pre-war levels, with peacetime targets of 16 squadrons, 13,000 personnel, and 144 operational aircraft by 1947.
The RAAF underwent significant reorganization under Air Marshal Sir Donald Hardman, who in 1953 restructured the force into three commands: Home Command (later Operational Command), Maintenance Command, and Training Command.
Korean War (1950-1953)
The RAAF was the first Australian military service to engage in the Korean conflict:
- No. 77 Squadron deployed directly from Japan where it had been part of the British Commonwealth Occupation Force
- Initially equipped with P-51 Mustangs, later transitioning to Gloster Meteor jets
- Flew nearly 19,000 sorties, primarily in ground attack roles once the Meteors proved outclassed by MiG-15s in air-to-air combat
Cold War Strategic Shift
The Cold War marked a significant shift in Australia’s strategic posture:
- Forward defense policy aimed at addressing threats as far from Australian shores as possible
- ANZUS Treaty (1951) formalized alliance with the United States, shifting from traditional British ties
- Acquisition of jet aircraft including the de Havilland Vampire (Australia’s first jet fighter) and the CAC Sabre (an Australian-built variant of the North American F-86)
Southeast Asian Operations
The RAAF made substantial contributions to regional security during this period:
Malayan Emergency (1948-1960):
- No. 1 Squadron with Avro Lincoln bombers conducted bombing missions against communist targets
- Multiple RAAF squadrons operated from Butterworth Air Base in northern Malaya
- Operation Termite (July 1954) featured coordinated air-ground assaults against communist strongholds
Indonesian Confrontation (1963-1966):
- No. 78 Wing deployed Sabre fighters at RAAF Butterworth
- RAAF aircraft conducted reconnaissance, maritime surveillance, and air defense operations
Vietnam War (1964-1972):
- RAAF Transport Flight Vietnam (later No. 35 Squadron) operated DHC-4 Caribou tactical transports
- No. 9 Squadron deployed UH-1 Iroquois helicopters in support of Australian ground forces
- No. 2 Squadron conducted bombing missions with Canberra aircraft
- RAAF units transported 42,000 tons of freight, 680,000 passengers, conducted 237,000 helicopter sorties, and performed 4,300 medical evacuations
Modernization and regional focus (1973-2000)
The post-Vietnam decades saw significant modernization of RAAF capabilities alongside a strategic shift toward greater self-reliance and focus on Australia’s immediate region.
Aircraft Modernization
Key acquisitions transformed the RAAF’s capabilities:
- F-111C strike aircraft finally entered service in 1973 after a decade of delays, providing Australia with a long-range strike capability that became a cornerstone of Australian air power
- F/A-18 Hornet fighters replaced the Mirage III from 1985, significantly enhancing air combat capabilities
- P-3C Orion maritime patrol aircraft strengthened Australia’s maritime surveillance operations
Strategic Reorientation
The withdrawal from Southeast Asia forced Australia to adapt its defense policy:
- Movement away from “forward defense” to a focus on defending Australia’s northern approaches
- Greater emphasis on self-reliance within the context of the US alliance
- Development of air bases in northern Australia to support operations in Australia’s maritime approaches
- Transfer of the RAAF’s battlefield helicopter capability to the Australian Army in 1989
International Operations
The RAAF contributed to numerous international operations in this period:
- UN peacekeeping missions in the Sinai, Cambodia, Rwanda, and Somalia
- First Gulf War (1990-1991) with Boeing 707 refueling tankers and RF-111C reconnaissance aircraft
- Operations in East Timor (1999-2000) as part of the International Force East Timor (INTERFET)
Global expeditionary operations (2001-2021)
The early 21st century saw the RAAF engaged in sustained operations across the globe, primarily in the Middle East. These operations demonstrated the RAAF’s ability to deploy and sustain forces at great distances from Australia.
Afghanistan Operations (2001-2021)
The RAAF made significant contributions to coalition operations in Afghanistan over two decades:
- C-130 Hercules and C-17A Globemaster transport aircraft provided crucial logistics support
- AP-3C Orion aircraft conducted surveillance missions

Conclusion
Over its century-plus history, the Royal Australian Air Force has transformed from a modest force of surplus WWI aircraft into a sophisticated, networked air force operating cutting-edge platforms. This evolution reflects Australia’s changing strategic circumstances, technological developments, and alliance relationships.
The RAAF’s capacity to adapt to evolving threats and embrace new technologies has ensured its position as a critical component of Australia’s defense capabilities. As geopolitical tensions increase in the Indo-Pacific region, the RAAF continues to focus on developing an integrated, fifth-generation force with enhanced range, lethality, and survivability to address emerging challenges in an increasingly complex and contested strategic environment.
