Den Canadair CF-5 (officielt betegnet CF-116 Freedom Fighter) er den canadiske licenserede version af det amerikanske Northrop F-5 Freedom Fighter-fly primært til de canadiske styrker (som CF-5) og Royal Netherlands Air Force (som NF-5). CF-5 blev opgraderet med jævne mellemrum gennem hele sin tjenestekarriere i Canada. De canadiske styrker trak typen tilbage i 1995, selvom CF-5'er fortsat bruges af andre lande.
Den Canadair CF-5was a fighter-bomber aircraft developed by Canadair under license from Northrop. It was based on the F-5 Freedom Fighter, but had several modifications to suit the needs of the Canadian Forces and the Royal Netherlands Air Force, who were the main operators of the CF-5. The CF-5 had a two-position nose landing gear that improved takeoff performance, a midair refueling probe, more powerful engines, and a more advanced navigation system. The CF-5 also had a removable nose that could be replaced with a reconnaissance module with four cameras. The CF-5 first flew in 1968 and entered service later that year. It was used for various roles, such as light attack, strike, reconnaissance, and training. The CF-5 was retired from Canadian service in 1995, but some countries still use it today.
