The Canadair CL-28 Argus (RCAF designation CP-107) was built in Montreal, Quebec. Created during the Cold War, the Argus was designed specifically for anti-submarine warfare, replacing the venerable Lancaster and the Neptune. It typically carried a crew of fifteen.

The Argus used the highest octane fuel of any non-racing, piston-driven aircraft and could fly for over 22 hours straight. However, the fuel was specialized, hard to come by, and was burned at a rate of 1135 litres per hour. Even so, the Argus Mark II remained in service for three decades, and the aircraft was considered highly effective at its job.

The National Air Force Museum of Canada’s CP-107 Argus was one of 20 Mark IIs purchased by the RCAF in 1958. Taken on strength on May 29, 1959, it flew with 405 (Maritime Patrol) Squadron at CFB Greenwood, NS and with 415 (Maritime Patrol) Squadron at Summerside, PEI. CP-10732 carries a distinctive Swordfish painted on its tail, from the crest of 415 Squadron. When 415 Squadron was moved to CFB Greenwood in 1988, the CP-107 Argus was replaced by the CP-140 Aurora.  At that time it became an instructional airframe, before moving into storage at CFB Trenton’s Aerospace Maintenance Development Unit (AMDU). It has been part of the collection at the National Air Force Museum of Canada since 1996.
