FSX/P3D v3,v4 CAC Boomerang. The Commonwealth Aircraft Corporation Boomerang was a single-seat fighter monoplane incorporating the principal features of the Wirraway. Designed and produced after the Japanese entered World War II as an emergency measure to strengthen the RAAF, 250 were built between 1942 and 1944 in four versions. Although not as good as the latest Japanese fighters, Boomerangs were successfully operated in New Guinea and elsewhere and also performed ground attack, target marking and reconnaissance duties.
