This Day in Aviation History
March 28th, 1957
First flight of the Canadair CP-107 Argus.

The Canadair CP-107 Argus (CL-28) was a marine reconnaissance aircraft designed and manufactured by Canadair for the Royal Canadian Air Force (RCAF) and Canadian Forces (CF). In its early years, the Argus was reputedly the finest anti-submarine patrol bomber in the world. The Argus served throughout the Cold War in the RCAF’s Maritime Air Command and later the CF’s Maritime Air Group and Air Command.

Canadair began work on the CL-28 in April 1954 and at the time it was the largest aircraft built in Canada. The hybrid design, initially referred to as the ‘Britannia Maritime Reconnaissance’, or ‘Britannia MR’, was derived from the Bristol Britannia transport, having the same wings, tail surfaces and landing gear except for being “Americanized” – meaning that it used the same general design, but changed the British materials and standard parts for North American ones.

The fuselage was completely redesigned by Canadair, going from the pressure cabin of the Britannia to an unpressurised one with bomb bays fore and aft of the wings. The powerplant was also changed from the Bristol Proteus turboprop engines to Wright R-3350 compound (piston) engines, which had lower fuel consumption necessary for extended missions at low level. At the design stage the other possible engine was the Napier Nomad, another turbo compound engine, although the Nomad was later cancelled…..
