The CAC CA-23 was a planned supersonic, twinjet, two-seat, all-weather fighter aircraft designed by Commonwealth Aircraft Corporation.

The CAC CA-23 delta wing design concept was a two-seat all-weather fighter with a low set tail.

It was originally planned to be powered by two Rolls-Royce Tay engines, the final version was however designed for the more powerful Rolls-Royce Avon turbojet engines.

The aircraft was to be fitted with the most up to date radar and electronic equipment.

Its anticipated performance was to be in the region of Mach 1.5 which would have been much faster than any contemporary aircraft.

The four-year project was cancelled in 1953 after the expenditure of £163,195 with extensive aeronautical R&D testing in wind tunnels in Australia and at the Royal Aircraft Establishment.

The testing results were so promising and ground breaking for a delta wing design that the Royal Aircraft Establishment requested permission to distribute the results to the major UK aircraft manufacturers and Avro Canada.
