The CAC CA-15, also known unofficially as the CAC Kangaroo, was an Australian propeller-driven fighter plane designed by the Commonwealth Aircraft Corporation (CAC) during World War II. During 1943, following the success of CAC in designing the small, makeshift Boomerang fighter, development began on a full-fledged interceptor and escort fighter. The prototype was handed over to the RAAF for testing and on 25 May 1948 and achieved a speed of 502.2 mph. The Kangaroo never entered service.
