While the Government initially planned to deploy the entire RAAF overseas, it later decided to focus the force's resources on training aircrew to facilitate a massive expansion of Commonwealth air-power. In late 1939, Australia and the other Dominions established the Empire Air Training Scheme (EATS) to train large numbers of men for service in the British Royal Air Force (RAF) and in other Commonwealth air units. Almost 28,000 Australians eventually trained through EATS in schools in Australia, Canada and Rhodesia. While many of these men were posted to Australian Article XV squadrons, the majority served with British and other Dominion squadrons. Moreover, these nominally "Australian" squadrons did not come under RAAF control and Australians often made up a minority of their airmen. As the Australian Government had no effective control over the deployment of airmen trained through EATS, most Australian historians regard the scheme as having hindered the development of Australia's defence capability. Nevertheless, RAAF airmen trained through EATS represented about nine percent of all aircrew who fought for the RAF in the European and Mediterranean theatres and made an important contribution to Allied operations.
