The McDonnell Douglas F-15 Eagle is a marvel of American military technology.
Developed in the late-1960s, the F-15 was faster and more maneuverable than it otherwise would have been because the United States thought the Soviet Mikoyan-Gurevich MiG-25, its direct competition, was a far more advanced plane than it actually was. It's been in service for almost a half-century now and is still being produced by Boeing, which absorbed McDonnell Douglas in the 1990s. It'll be in service with the U.S. Air Force until at least the 2030s.
Remarkable though the plane may be, there are limits to what the F-15 can do. As Airforce Technology noted, the F-15 is at present "almost exclusively used for close-air support" by the Air Force. It has a ground-strike capability if need be, although that need is unusual. It's not used in reconnaissance roles.
