Unfortunately, the design and testing stage of the CF-105 had burned through more than $1.58 billion dollars in today’s money. The Canadian government knew they would have to pump in more resources to bring the airplane to serial production. Prime Minister John Diefenbaker was not ready to make that kind of commitment.
As a bomber, the F-105 could carry either a single nuclear weapon internally or the jet could carry a conventional bomb load larger than World War II-era bombers like the B-17 or B-24
Development of the CF-105 initially progressed quickly. It was one of the most advanced aircraft of its day, but it was also widely praised for its power and beauty. The Arrow helped to establish Canada as a world leader in scientific research and development.
