Canadair CP-107 Argus

The CL- 28 is a maritime patrol and anti-submarine - hunting aircraft from the Canadian manufacturer Canadair.

History and construction

Canadair began work on the CL -28 in April 1954. At that time it was the largest aircraft ever built in Canada. The CL -28 was derived from the Bristol Britannia, with the same wings, tail and undercarriage, but " Americanized " - which means that, although using the same basic design, but the British materials and standard parts have been converted to North American sizes. The hull was completely redesigned by Canadair, from the pressurized cabin of Britannia to a non-pressurized, front with bomb bays fitted behind the wings and new hull with reinforced structure. As engines Turbo -compound engines were chosen because they had lower fuel consumption instead of the Bristol Proteus turboprop Wright R -3350, which extended patrol missions were possible. The Argus Mk I first flew on 28 March 1957 by the Canadair factory in Montreal from. This was followed by 12 other machines with Mk I Standard. This was followed by 20 copies of the Argus Mk II production ended in July 1960. Earlier in her career, the CP -107 Argus was how it was described by the Canadian Air Force, as the best aircraft of its kind

The Argus replaced with the Royal Canadian Air Force, the Lancaster and Neptune used until then in the maritime reconnaissance and anti-submarine warfare.
