The F-15 Eagle is a dominant aircraft, unrivaled in air-to-air combat—still in active service, and credited with over 100 aerial kills without a single loss.
The McDonnell Douglas F-15 Eagle is one of the most respected fighter aircraft ever built. Boasting an undefeated air-to-air record, the F-15 is an air superiority virtuoso benefitting from exceptional maneuverability and handling characteristics combined with raw power.

The F-15 Eagle Is Agile—and Really, Really Fast
At the heart of the F-15’s performance capabilities is a thrust-to-weight ratio in excess of 1:1, even when loaded with a typical combat payload—one of the first fourth-generation fighter jets to achieve this ratio. The benefit of the 1:1 trust-to-weight ratio is the ability to accelerate vertically, a performance marker that few aircraft can match. The F-15’s two powerful Pratt & Whitney F100 engines give the jet remarkable acceleration and a top speed in excess of Mach 2.5—good enough to make the F-15 one of the fastest operational jets ever. In practice, the F-15’s power means that the pilot can dictate the terms of engagement over a slower foe, choosing when to close, when to disengage, and when to climb vertically—without the aircraft’s power being a limiting factor.
But the F-15’s enviable performance envelope isn’t just about power. It’s about the pairing of remarkable power with deft agility. Designed with large, highly swept wings and a broad lifting fuselage, the F-15 enjoys exceptional lift and stability, even when operating in high-angle-of-attack maneuvers. The wings have a relatively low wing load, meaning the aircraft can generate more lift per unit of weight, resulting in tighter turns and greater stability at high speeds. And, with a broad chord and leading-edge extension, the airflow separation over the wing is delayed, giving there pilot more control authority in demanding maneuvers. Further enhancing maneuverability, the F-15 features oversized control surfaces, allowing for rapid aileron rolls, tight turns, and abrupt pitch changes—all possible without bleeding too much energy. Specifically, the twin vertical stabilizers provide stability during aggressive yaw and roll inputs. And that ability, to maintain high energy even in demanding flight envelopes, makes the F-15 a dominant aircraft in WVR dogfights, where the loss of energy (speed) can be fatal.
The F-15 Was Far Ahead of Its Time
Lastly, the F-15’s flight control system also lends to the jet’s exceptional handling. And even though the system was designed before the full digital fly-by-wire system found on modern jets, the F-15’s mechanical-hydraulic controls are finely tuned and extremely responsive. Pilots have consistently described the F-15 as a predictable and forgiving aircraft, even when pushing the flight envelope. The balance point between stability and agility gives the pilot enhanced confidence to keep pushing the aircraft aggressively—with the knowledge that the jet will remain controllable and responsive, even at the outer limit of its capabilities.
In operational terms, what all of this adds up to is a dominant aircraft, unrivaled in air-to-air combat—still in active service, and credited with over 100 aerial kills without a single loss. The F-15 was far ahead of its time when first fielded in the 1970s, and it is still relevant today. While newer, fifth-generation fighters have emerged that can outperform it, the F-15 remains a benchmark for enduring air-to-air dominance. And with the advent of the F-15’s new EX variant—keeping the F-15’s speed and agility and giving it modern electronics—expect the Eagle platform to stay relevant for many years to come.
