The McDonnell Douglas CF-18 Hornet (official military designation CF-188) is a Royal Canadian Air Force (RCAF) variant of the American McDonnell Douglas F/A-18 Hornet fighter aircraft. In 1980, the F/A-18 was selected as the winner of the New Fighter Aircraft Project competition and awarded a production order; deliveries of the CF-18 to the Canadian Armed Forces began in 1982. CF-18s have supported North American Aerospace Defense Command (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 were also part of the Canadian contribution to the military intervention against ISIL, Operation Impact.
