The Commonwealth Aircraft Corporation (CAC) had envisioned the development of the CAC CA-23, an advanced fighter aircraft characterised by its supersonic capabilities, twinjet configuration, and two-seat capacity.

This cutting-edge design incorporated a delta wing and a tail positioned at a low height.

Originally, the intention was to equip the aircraft with two Rolls-Royce Tay engines.

However, the final iteration of the CA-23 was tailored to accommodate the more potent Rolls-Royce Avon turbojet engines.

In terms of avionics, the CA-23 was intended to be outfitted with state-of-the-art radar and electronic equipment, ensuring optimal performance in all weather conditions.

The anticipated performance of the CAC CA-23 was truly remarkable, with projected speeds reaching Mach 1.5.

This would have positioned the CA-23 as a significantly faster aircraft compared to its contemporaries.

The development of this ambitious project spanned four years, during which £163,195 was expended.

Extensive research and development testing were conducted in wind tunnels located in Australia and at the prestigious Royal Aircraft Establishment.

The results of these tests were highly promising and groundbreaking, particularly in relation to the delta wing design.

As a result, the Royal Aircraft Establishment sought permission to disseminate these findings to major aircraft manufacturers in the United Kingdom and Avro Canada.

Regrettably, despite the significant progress made and the potential demonstrated by the CA-23, the project was ultimately terminated in 1953.

The decision to cancel the project came after substantial investments had been made.

Nonetheless, the knowledge gained from the extensive testing and research conducted during the development of the CAC CA-23 would undoubtedly contribute to future advancements in aeronautics and the design of fighter aircraft.
