The CAC Mustang is an Australian-operated variant of the North American P-51 Mustang, a World War II-era fighter aircraft known for its speed, range, and combat performance.

The Mustang was a key platform in long-range escort and air superiority operations during World War II, providing protection for bomber formations and contributing significantly to Allied air operations across multiple theatres.

The aircraft is powered by a high-performance piston engine and is recognised for its exceptional speed, aerodynamic efficiency, and combat effectiveness for its era. Its continued operation today reflects its enduring engineering and historical significance.
