J-20 5th Gen Fighter Thread VIII

If RAM materials can be designed to benefit from the "quenching" effect, high heat from supersonic flights and hot sun would not be a problem.

Surviving is one thing, but your IR signature becomes a massive problem at high supersonic.

Ha, that's true. But no stealth fighters can travel M5+... For now.

You don’t need to travel at Mach 5. The missile needs to close distance in order to reach you and has limited propellant. The faster you can dash when the missile is coming the more likely you are to escape. If an IR missile is fired at you that means it already got a lock anyways, so flying faster isn’t going to make you that much more seen.

Well, I was thinking more of the SR-71 approach where you straight-up outrun the missile, but I guess that works too.
