By the time adversaries detect the Raptor, it has often already fired missiles and maneuvered to a superior position. On the other hand, the F-15 might outrun its targets but retains a larger radar cross-section and can be tracked and engaged by many more enemies.

The Eagle relies on its high thrust-to-weight ratio and robust radar suite for air intercept, whereas the Raptor leverages stealth and sensor fusion to stalk its prey.

Each philosophy that is imbued in the two designs reflects the doctrine from the eras of their development. The 1970s favored dominance through speed and heavy weapons, while modern tactics focus on evading detection and maximizing electronic warfare (EW) techniques.
