Avro Canada CF-103
The Avro Canada CF-103 was a proposed Canadian interceptor, designed by Avro Canada in the early 1950s as a development, and possible replacement of the company's CF-100 Canuck, that was entering service at the time with the Royal Canadian Air Force (RCAF). Although intended to be capable of flying at transonic speeds, the CF-103 only offered a moderate increase in performance and capability over the CF-100; subsequently, the aircraft never progressed beyond the mock-up stage.
