The CAC Wirraway (an Aboriginal word meaning "challenge") was a training and general purpose military aircraft manufactured in Australia by the Commonwealth Aircraft Corporation (CAC) between 1939 and 1946. It was an Australian development of the North American NA-16 training aircraft. The Wirraway has been credited as being the foundation of Australian aircraft manufacturing.
During the Second World War, both the Royal Australian Air Force (RAAF) and Royal Australian Navy (RAN) deployed a number of Wirraways into combat roles, where they served in a makeshift light bomber/ground attack capacity, striking against the advancing forces of the Empire of Japan.
While the type had been primarily used as a trainer and general purpose aircraft, being present in small quantities within the majority of front-line squadrons for these purposes, the aircraft was often pressed into combat when required.
