The F-15 Eagle is a twin-engine tactical fighter designed by McDonnell Douglas in 1967. The all-weather plane is designed to gain and maintain air superiority over enemy forces during aerial combat, which involves holding dominant positions in the sky. The F-15 Eagle first flew in July 1972, and officially entered service in the U.S. Air Force in 1976.
F-15s are capable of flying at speeds greater than Mach 2.5 (1,650 mph, or 2,655 km/h), and are considered one of the most successful planes ever created. The F-15 Eagle is expected to continue flying in the U.S. Air Force beyond 2025, and have also been exported to a number of foreign nations, including Japan, Israel and Saudi Arabia.
