The McDonnell Douglas CF-18 Hornet (official military designation CF-188) is a Royal Canadian Air Force (RCAF) (formerly Canadian Forces Air Command) fighter aircraft, based on the American McDonnell Douglas F/A-18 Hornet fighter. In 1980, the F/A-18 was selected as the winner of the New Fighter Aircraft Project competition, and a production order was awarded. The Canadian Forces began receiving the CF-18 in 1982. CF-18s have supported NORAD air sovereignty patrols and participated in combat during the Gulf War in 1991, the Kosovo War in the late 1990s, and as part of the Canadian contribution to the international Libyan no-fly zone in 2011. CF-18s are also part of the Canadian contribution to the Military intervention against ISIL, Operation Impact, which began in September 2014.
