CS2F Grumman (de Havilland) Tracker
The Tracker was a twin-engine fixed-wing aircraft acquired by the Royal Canadian Navy (RCN) to be flown off aircraft carriers for antisubmarine warfare (ASW) as a replacement for the Grumman Avenger. Originally developed for the United States Navy (USN), a Canadian version was manufactured under licence by de Havilland Canada as the CS2F. After unification the plane was redesignated as the CP-121; the Trackers became shore-based aircraft after the aircraft carrier HMCS Bonaventure was decommissioned. The Trackers became fully operational in 1959 and were withdrawn from service in 1989.
