The Commonwealth Boomerang was a World War II fighter aircraft designed and manufactured in Australia between 1942 and 1945. The Commonwealth Aircraft Corporation (CAC) produced Boomerangs under the production contract numbers CA-12, CA-13, CA-14 and CA-19, with aircraft supplied under each subsequent contract incorporating modifications and improvements. The Boomerang is significant as the first combat aircraft designed and built in Australia. The Boomerang was a small fighter, designed with an emphasis on manoeuvrability. It had an overall length of just 7.7 metres (25.5 ft) and an 11 m (36 ft) wingspan. It was very well-armed, with two 20 mm cannon and four .303 calibre (7.7 mm) machine guns, all mounted in the short, thick wings. The Boomerang was also generously equipped with armour plating to protect the pilot. The Boomerang found its real use as a close support aircraft. In contrast to Europe or North Africa, the ground war in the jungles of the south-west Pacific was, in broad terms, a series of small unit actions fought at very close quarters by widely dispersed forces with no clear front lines. It was here that the Boomerang found its niche: as close to the troops on the ground as possible.
