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.[3] 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.

Design and development
Canadair began work on the CL-28 in April 1954 and theLok time it was the largest aircraft built in Canada. The hybrid design was derived from the Bristol Britannia transport, having the same wings, tail surfaces and landing gear except for being "Americanized" - meaning it used the same general design, but changing 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 a non-pressurised one with bomb bays fore and aft of the wings. The powerplant was also changed from the Bristol Proteus turbo-prop engines to Wright R-3350 turbocompound engines, which had lower fuel consumption necessary for extended missions.
Operational history
The Argus replaced the Lancaster and Neptune aircraft types previously flown in RCAF maritime roles. One of the most effective anti-submarine warfare (ASW) aircraft of its day, the Argus was a mainstay for the RCAF. A large amount of equipment was carried, including search radar, sonar buoys, electronic counter measures (ECM), explosive echo ranging (EER) and Magnetic anomaly detector (MAD). Up to 8,000 lb (3,632 kg) of weapons could be carried in the bomb bays, including torpedoes, bombs, mines and depth charges.
A flight crew of five consisting of two pilots, a navigator, a flight engineer and a radio operator plus relief crew of four was normally carried. In addition, there were six or more ASW equipment operators, the number of which was dependent on the mission. Two crew bunks and a galley were provided to extend the efficiency of the crew on long patrols. The CL-28 had an endurance of approximately 26½ hours. An Argus flown by 407 Maritime Patrol Squadron held the record for the longest flight by an unrefuelled aircraft, slightly over 31 hours.
The principal difference between the Mark I and Mark II was primarily in the different navigation, communication and tactical electronic equipment fitted internally. Externally, the Mk II exhibited a redesigned smaller nose radome and additional ECM antennae above the fuselage.
The Argus flew its last service mission on 24 July 1981, and was replaced by the CP-140 Aurora.
