The Boeing F-15 Eagle is an American twin-engine, all-weather tactical lighter aircraft designed by McDonnell Douglas (now Boeing) to gain and maintain air supremacy in aerial combat. Following reviews of proposals, the United States Air Force selected McDonnell Douglas’ design in 1967 to meet the service’s need for a dedicated air superiority lighter. The Eagle first flew in July 1972, and entered service in 1976. It is among the most successful modern fighters, with over l 00 victories and no losses in aerial combat, with the majority of the kills by the Israeli Air Force. The Boeing F-15 Eagle has been exported to Israel, Japan, and Saudi Arabia. The F-15 was originally envisioned as a pure air superiority aircraft.
