Why Does The US Air Force Still Fly The F-15?

More than five decades after it first entered service, the McDonnell DouglasF-15 Eagle continues to fly combat missions for the United States Air Force (USAF). This longevity raises an obvious question: why does the US Air Force still operate the F-15 when numerous stealth aircraft are in service, such as the F-22 Raptor and the F-35 Lightning II? At first glance, maintaining a fighter originally designed in the late 1960s may appear surprising for a military that prides itself on technological superiority. But the continued presence of the Eagle reflects a deeper reality about modern airpower: proven aircraft can remain extremely effective when properly upgraded and integrated into modern combat doctrine.
