Lost Classics - AVRO Arrow

Enlarge image (will open in a new window) The Avro Canada CF-105 Arrow was, in 1959, one of the most advanced interceptor fighters in the world. Its development began in 1953, as a replacement for the CF-100 Canuck two-seat all-weather fighter which was then just entering service with the Royal Canadian Air Force (RCAF). It was a matter of forward-thinking. The CF-100 was not under criticism, but it took years to develop a supersonic interceptor.

By April 1954, after enthusiastic pursuit of design development, the first five Arrow Mk.1 prototypes were in production. The name came from the new aircraft's high-set delta wing on a needle-nosed fuselage. Inlets each side of the tandem cockpit fed two turbojets mounted side by side in the fuselage.

Enlarge image (will open in a new window) Having passed through various design changes since 1953, an order was placed for 37 development and pre-production aircraft in 1957. The first prototype Mk.1 flew on 25th March, 1958. The first five Arrow Mk.1s (RL-201 to RL-205) were powered by Pratt & Whitney J75 engines.It was intended to introduce engines of Canadian design and manufacture from the sixth aircraft, designated Arrow Mk.2. These would have been the PS-13 Iroquois turbojet developed by Orenda. These were rated at 19,250 lb. st (85.63 kN) dry and 26,000 lb. st (115.65 kn) afterburning.

During flight trials, the Mk.1 attained Mach 2.3, and exceeded 1,000 mph (1610 km/h) at 50,000 ft (15,240 m), with the aircraft still climbing.

All five Mk.1s flew before February 1959, and the first Mk.2 was on the point of flying, with aircraft seven to ten nearing completion. The Canadian Prime Minister, Mr. Diefenbaker, announced termination of the project on 20th February, 1959, after an expenditure of some £108M.

Destruction of all five Arrow Mk.1s, the unflown Mk.2 and the four near-complete aircraft was ordered. Only three years later, Canada found it necessary to obtain from the US the two-seat McDonnell F-101B Voodoo to fill the role for which the Arrow had been designed.
