@skunk.51: The F-15 will probably outlive the F-22 Raptor because the legendary jet is still rolling off the assembly line while the Raptor is permanently capped. Boeing is actively building brand-new F-15EX "missile trucks" with fresh airframe lifespans ready to fly into the 2040s. Meanwhile, the elite but tiny 187-ship F-22 fleet is aging fast under brutal maintenance costs and structural wear, putting it on a strict countdown to retirement in the mid-2030s when the sixth-generation F-47 takes over.
