CAC Boomerang Aircraft Overview
The CAC Boomerang was a fighter plane developed and manufactured by the Commonwealth Aircraft Corporation (CAC) of Australia during World War II. The Boomerang was designed as a single-seat fighter aircraft primarily for the purpose of home defense. It was built using available components and featured a unique “cranked” wing design.
The CAC Boomerang was not intended to be a high-performance fighter but rather a capable aircraft that could be quickly produced using existing resources. It served mainly in the Pacific theater during World War II, providing close air support and reconnaissance missions.
The Boomerang’s production was relatively limited, with approximately 250 aircraft built. Despite its limited numbers and modest performance, the Boomerang proved to be a reliable and versatile aircraft that served its purpose effectively in the defense of Australia during the war.
