Searching for Supply: Australian Air Force Expansion and United States Operational Aircraft, 1935–1941

When Japan attacked European and U.S. possessions in the Asia-Pacific region in December 1941, the Australian government had on order more combat-ready operational aircraft from American firms than from Australian and British industries combined. The U.S. was thus critical to the equipping and expansion of the Royal Australian Air Force. This article demonstrates that the framework of imperial defense provided a means by which the Australian government sought to secure American supply, although pressures on U.S. industry ultimately delayed the Australia air force’s modernization and expansion program in 1940–1941. The war with Japan nonetheless created the potential for a more direct Australian-American relationship.
