The Avro Canada CF-105 "Arrow", a supersonic two-seat all-weather interceptor, designed and produced by Avro Aircraft Limited was introduced for the RCAF in Malton, Ontario, October 4, 1957, the same day as the first Russian " Sputnik "criticized outside the orbit. The RCAF had decided to develop its own supersonic interceptor when no known project could meet its specifications for a two-seat, twin-engine machine with advanced firepower, capable of a speed of Mach 2.5, the range of approximately 2,000 miles and an operational ceiling of 60,000 feet.
