Design and Development
In the early 1950s, Canada needed an all-weather interceptor (fighter) able to patrol the vast areas of Canada's north and operate in all weather conditions. The two-seat fighter crewed by a pilot and navigator was designed with two powerful engines and an advanced radar and fire control system housed in its nose that enabled it to fly in all-weather or night conditions.
Design of the XC-100 to meet a Royal Canadian Air Force (RCAF) specification for an all-weather fighter was initiated at Avro Canada in October 1946. Chief Engineer Edgar Atkin's work on the CF-100 was subsequently passed to John Frost (formerly of de Havilland) who, along with Avro's Chief Aerodynamacist Jim Chamberlin, reworked the original fuselage design. The CF-100 Mark 1 prototype, "18101," emerged out of the factory, painted gloss black overall with white lightning bolts running down the fuselage and engines. The CF-100 prototype flew its maiden flight on 19 January 1950 with Gloster Aircraft Company Chief Test Pilot Squadron Leader Bill Waterton at the controls. Waterton was on loan from the Gloster firm, another member of the Hawker Siddeley Group, and chosen because of his experience with jet aircraft development, as one of the "highest-time" pilots in the world. The Mark 1 was powered by two Avon RA 3 turbojets with 28.9 kN (2,950 kgp / 6,500 lbf) thrust each.
The second prototype, 18102, was also powered by Rolls-Royce Avons, although subsequent pre-production and production series aircraft used the Avro Orenda turbojet. Five pre-production Mk 2 test aircraft were produced (18103-18107) all fitted with the Orenda 2 jet engines; one was fitted with dual controls and designated a Mk 2T trainer. The first production version, designated Mk 3, incorporated the APG-33 radar and was armed with eight .50 caliber (12.7 mm) machine guns. The Mk 3CT and Mk 3DT were again dual control versions supplied to operational training units.
A CF-100 arrived at Eglin AFB, Florida, in mid-January 1955 for cold-weather tests in the climatic hangar. A seven-man RCAF team, headed by Flight Lieutenant B. D. Darling, which had previously conducted tests at Namao Air Base, Alberta, were part of the climatic detachment of Central Experimental and Proving Establishment. Tests were to begin in February.
In March 1956, four CF-100 Canucks were sent to Eglin AFB for comparative armament trials, and flown by USAF crews. The operational suitability tests, dubbed Project Banana Belt, were carried out by the 3241st Test Group (Interceptor) of the APGC's Air Force Operational Test Center, in conjunction with a project team from the Royal Canadian Air Force.

Famous quotes containing the words design and/or development:
“Nowadays the host does not admit you to his hearth, but has got the mason to build one for yourself somewhere in his alley, and hospitality is the art of keeping you at the greatest distance. There is as much secrecy about the cooking as if he had a design to poison you.”
—Henry David Thoreau (1817–1862)
“On fields all drenched with blood he made his record in war, abstained from lawless violence when left on the plantation, and received his freedom in peace with moderation. But he holds in this Republic the position of an alien race among a people impatient of a rival. And in the eyes of some it seems that no valor redeems him, no social advancement nor individual development wipes off the ban which clings to him.”
—Frances Ellen Watkins Harper (1825–1911)
