Developing fighter jets is hard and is a feat only a few countries succeed in ( Israel also failed with its IAI Lavi fighter). Canada attempted to produce the Avro Arrow CF-105 supersonic interceptor in the 1950s for the Canadian Air Force. But while the design showed promise, it was canceled by the Canadian government in 1959. Had it been developed, it was planned to be Canada’s primary interceptor, and many thought it heralded a bright future for the Canadian aviation industry.
