RAAF Centenary Timeline

First CAC Boomerang Operational Flight – 10 April 1943

The first prototype of the Commonwealth Aircraft Corporation Boomerang conducted its maiden flight on 29 May 1942,[i] but it was not until 10 April 1943 that the aircraft would see operational use.[ii] The Boomerang is significant because it was the first fighter plane completely designed and manufactured in Australia. It followed the CAC Wirraway, a single-engine training aircraft introduced in 1939.

No. 83 Squadron RAAF were the first to receive Boomerangs, followed closely by No. 84 Squadron. No. 4 and No. 5 Squadrons also flew Boomerangs in New Guinea.[iii] The Boomerang was a flawed aircraft, with poor forward visibility and a tendency to become damaged on landing due to ground looping, a process in which a wingtip makes contact with the ground.[iv] The Boomerang was a useful aircraft for home operations such as anti-malarial spraying and reconnaissance,[v] but other fighters such as the Curtiss P-40E Kittyhawks were preferred by RAAF units operating overseas.
