The growth of the RAAF expanded to about 4 times this size by late 1940 and expanded about the same amount again after the Japanese strike. 

Training establishments expanded to about 40 by the end of the war.

Unlike the Army the RAAF had planned, with industry, for war with Japan and by March-April 1942 were in a good position to defend Australia, despite the panic of the government and the people.

Note: In 1940 the formation of the Article XV Squadrons as part of the Empire Air Training Scheme occurred. These units were formed to support Britain in the ETO and, in most cases stayed in the ETO for the duration. The casualties sustained by the Article XV units represent about 25% of all casualties suffered by Australia in the Second World War, and on a pro rata base far exceed any other branch of the Australian Armed Forces.
