Design

CAC developed the Boomerang as an answer to the possibility of a Japanese invasion of Australia.1,2 Lawrence Wackett was the head designer for Commonwealth Aircraft Corporation.2 Development was rushed to get it produced as quickly as possible and within five months it was designed, built, and flown.1,2

However, the Boomerang didn't see service until March 1943, by which time P-40 Kittyhawks and Supermarine Spitfires were being delivered.1

First Battle

Army Cooperation
