Canadair CP-107 Argus

Canadair · Canada · first flew 1957 · transport aircraft

The Canadair CP-107 Argus was a long-range maritime patrol aircraft developed for the Royal Canadian Air Force, combining the wing and undercarriage of the Bristol Britannia with a new unpressurised fuselage optimised for low-level anti-submarine work. It was one of the most capable maritime patrol aircraft of its era.

WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

Four large radial engines on a very long-span low wing, a deep unpressurised fuselage with a distinctive chin radome, and no pressurisation windows distinguish it from the civil Britannia.

History

First flown in 1957 and entering RCAF service in 1958, the Argus was designed for ultra-long endurance patrol over the North Atlantic, capable of patrols exceeding 26 hours. It used four Wright R-3350 Turbo-Compound piston engines for their fuel efficiency at low altitude rather than turbines.

Variants

The Mk.1 carried British search radar; the Mk.2 switched to American AN/APS-20 radar in a different nose profile.

Where you'll see it

Served exclusively with RCAF Maritime Command (later Canadian Armed Forces) from 1958 to 1981 when it was replaced by the CP-140 Aurora; no foreign operators.
