The Avro Arrow, a Canadian supersonic interceptor aircraft, was developed over a period of about five years. The project officially began in 1953, with the first prototype, the CF-105 Arrow, making its maiden flight on March 25, 1958. However, the program faced challenges, and despite its advanced design and capabilities, it was controversially canceled in 1959, just a year after the first flight.
