(RAAF). The AFC was established in 1912, though it was not until 1914 that it began flight training. In 1911, at the Imperial Conference held in London, it was decided that aviation should be developed by the national armed forces of the

. Australia became the first member of the Empire to follow this policy. By the end of 1911, the Army was advertising for pilots and mechanics. During 1912, pilots and mechanics were appointed, aircraft were ordered, the site of a flying school was chosen and the first squadron was officially raised. On 7 March 1913, the government officially announced formation of the Central Flying School (CFS) and an "Australian Aviation Corps", although that name was never widely used. AFC units were formed for service overseas with the Australian Imperial Force (AIF) during World War I. They operated initially in the

. The AFC later saw action in Palestine and France. A training wing was established in the United Kingdom. The corps remained part of the Australian Army until it was disbanded in 1919, after which it was temporarily replaced by the Australian Air Corps. In 1921, that formation was re-established as the independent RAAF.


Establishment

On 30 December 1911, the '' Commonwealth Gazette'' announced that the Australian military would seek the "...appointment of two competent Mechanists and Aviators", adding that the government would "accept no liability for accidents". On 3 July 1912, the first "flying machines" were ordered: two Royal Aircraft Factory B.E.2 two-seat

On 22 September 1912, the Minister of Defence, Senator George Pearce, officially approved formation of an Australian military air arm. Petre rejected a suggestion by Captain Oswald Watt that a Central Flying School be established in Canberra, near the

, on 22 October 1912. Two days later, on 24 October 1912, the government authorised the raising of a single squadron. Upon establishment the squadron would be equipped with four aircraft and manned by "...four officers, seven warrant officers and sergeants, and 32 mechanics", drawn from volunteers already serving in the Citizen Forces. On 7 March 1913, the government officially announced formation of the Central Flying School (CFS) and the "Australian Aviation Corps". According to the

The first mention of an Australian Flying Corps appears in Military Orders of 1914." Flying training did not begin immediately; it was not until 1914 that the first class of pilots were accepted. No. 1 Flight of the Australian Flying Corps was raised in the 3rd Military District on 14 July 1914. In March 1914, a staff officer, Major

Following the outbreak of World War I and the expansion of the Army, aviation became a separate branch commanded by Reynolds. AFC operational units were attached and subordinate to Australian ground forces and/or British ground and air commands. Reynolds' role was mostly administrative rather than one that involved operational command.

Flying DH.5 fighters, the squadron made its debut around St Quentin, fighting a short action with a German patrol and suffering the loss of one aircraft forced down. The following month the squadron took part in the Battle of Cambrai, flying on combat air patrols, and bombing and strafing missions in support of the British Third Army, suffering heavy losses in dangerous low-level attacks that later received high praise from General Hugh Trenchard, commander of the RFC.

Operations continued until the end of the war, some of the fiercest air-to-air fighting occurring on 29 October, when 15 Sopwith Snipes from No. 4 Squadron fought an engagement with a group of Fokkers that outnumbered them four to one. In the ensuing fighting, the Australians shot down 10 German aircraft for the loss of just one of their own. During their time along the Western Front, the two fighter squadrons – No. 2 and 4 – accounted for 384 German aircraft, No. 4 taking credit for 199 and No. 2 for 185. The squadron were also credited with 33 enemy balloons destroyed or driven down. No. 3 Squadron, operating in the corps reconnaissance role, accounted for another 51 aircraft.


Organisation

By the end of the war, four squadrons had seen active service, operating alongside and under British Royal Flying Corps (and in 1918 the

) command. For administrative reasons, and to avoid confusion with similarly numbered RFC units, at one stage each AFC squadron was allocated an RFC number – the Australians themselves never used these numbers, and in the end, to avoid further confusion, the original AFC numbers were reinstated. The four operational squadrons of the AFC were: In the Middle East, No. 1 Squadron was initially assigned to No. 5 Wing after being formed, but was later transferred to No. 40 Wing in late 1917, remaining as part of that formation until the end of the war. In Europe, No. 2 Squadron formed part of No. 51 Wing, but in 1918 it was transferred to No. 80 Wing, joining No. 4 Squadron which had been transferred from No. 11 Wing. No. 3 Squadron trained as part of No. 23 Wing until it was committed to the Western Front in August 1917, when it became a "corps squadron", tasked with supporting the British XIII and

. As well as the operational squadrons, a training wing was established in the United Kingdom. Designated as the 1st Training Wing, it was made up of four squadrons. The four training squadrons of the AFC were: As the war progressed, there were plans to increase the AFC's number of operational squadrons from four to fifteen by 1921, but the war came to an end before these could be raised.


Personnel

The corps remained small throughout the war, and opportunities to serve in its ranks were limited. A total of 880 officers and 2,840 other ranks served in the AFC, of whom only 410 served as pilots and 153 served as observers. A further 200 men served as aircrew in the British flying services – the RFC or the
Royal Naval Air Service The Royal Naval Air Service (RNAS) was the air arm of the Royal Navy, under the direction of the Admiralty's Air Department, and existed formally from 1 July 1914 to 1 April 1918, when it was merged with the British Army's Royal Flying Corps t ...
(RNAS) – including men such as Charles Kingsford Smith and Bert Hinkler, both of whom would have a significant impact upon aviation in Australia after the war. Casualties included 175 dead, 111 wounded, 6 gassed and 40 captured. The majority of these casualties were suffered on the Western Front where 78 Australians were killed, 68 were wounded and 33 became prisoners of war. This represented a casualty rate of 44 percent, which was only marginally lower than most Australian infantry battalions that fought in the trenches, who averaged a casualty rate of around 50 percent. Molkentin attributes the high loss rate in part to the policy of not issuing pilots with parachutes, as well as the fact that the bulk of patrols were conducted over enemy lines, both of which were in keeping with British policy. Pilots from the AFC's four operational squadrons claimed 527 enemy aircraft destroyed or driven down, and the corps produced 57 flying aces. The highest-scoring AFC pilot was Harry Cobby, who was credited with 29 victories. Other leading aces included Roy King (26),

Equipment

The Australian Flying Corps operated a range of aircraft types. These types were mainly of British origin, although French aircraft were also obtained. Over this period aircraft technology progressed rapidly and designs included relatively fragile and rudimentary types to more advanced single-engined biplanes, as well as one twin-engined bomber. The roles performed by these aircraft evolved during the war and included reconnaissance, observation for artillery, aerial bombing and ground attack, patrolling, and the resupply of ground troops on the battlefield by airdrop.


Training

The AFC conducted both pilot and mechanic training in Australia at the Central Flying School, which was established at Point Cook, but this was limited in duration due to embarkation schedules, which meant that further training was required overseas before aircrew were posted to operational squadrons. The first course began on 17 August 1914 and lasted three months; two instructors, Henry Petre and Eric Harrison, who had been recruited from the United Kingdom in 1912 to establish the corps, trained the first batch of Australian aircrew. In the end, a total of eight flying training courses were completed at the Central Flying School during the war, the final course commencing in June 1917. The first six courses consisted only of officers, but the last two, both conducted in early and mid-1917 included non-commissioned officers. These courses ranged in size from four on the first course, to eight on the next three, 16 on the fifth, 24 on the sixth, 31 on the seventh and 17 on the last one. There was limited wastage on the early courses, all trainees successfully completing the first six courses, but final two courses run in 1917 suffered heavily from limited resources and bad weather, resulting in less than half the students graduating. To complement the aviators trained by the CFS, the

government established its own aviation school at Clarendon, at what later became RAAF Base Richmond, which trained pilots, observers and mechanics. A total of 50 pilots graduated from the school, the majority of its graduates went on to serve in the British flying services, although some served in the AFC. In early 1917, the AFC began training pilots, observers and mechanics in the United Kingdom. Aircrew were selected from volunteers from other arms such as the infantry, light horse, engineers or artillery, many of whom had previously served at the front, who reverted to the rank of cadet and undertook a six-week foundation course at the two Schools of Military Aeronautics in

in Gloucestershire. Flight training in the UK consisted of a total of three hours dual instruction followed by up to a further 20 hours solo flying – although some pilots, including the AFC's highest-scoring ace, Harry Cobby, received less – after which a pilot had to prove his ability to undertake aerial bombing, photography, formation flying, signalling, dog-fighting and artillery observation. Elementary training was undertaken on types such as Shorthorns, Avro 504s and Pups, followed by operational training on Scouts, Camels and RE8s. Upon completion, pilots received their commission and their "wings", and were allocated to the different squadrons based on their aptitude during training: the best were usually sent to scout squadrons, and the remainder to two-seaters. Initially, the AFC raised its ground staff from volunteer soldiers and civilians who had previous experience or who were trade trained, and when the first AFC squadron was formed these personnel were provided with very limited training that was focused mainly upon basic military skills. As the war progressed, a comprehensive training program was established in which mechanics were trained in nine different trades: welders, blacksmiths, coppersmiths, engine fitters, general fitters, riggers, electricians, magneto-repairers, and machinists. Training was delivered by eight technical sections at Halton Camp. The length of training within each section varied, but was generally between eight to 12 weeks; the more complex trades such as engine fitter required trainees to undertake multiple training courses across several sections. General fitters had the longest training requirements, receiving 32 weeks of instruction.
