yep. you could hide from radar, but thermals or acoustics would give you away. if you’re trucking mach 5 leading edge friction alone might give you away even if you’re coated with RAM and aerogels and magic dope.

I suspect it’s just Lockheed wringing more ‘magic’ out of the skunkwork’s legacy. I don’t doubt the aircraft will be awesome, but like the f22, it’ll be limited by physics and budgets and we’ll wonder what the competing runner-up would do better/cheaper/faster.

See: YF23 heh.

That said I really do hope the Skunworks is still making magic we just aren’t cleared for, and maintain the Kelly Johnson / Ben Rich legacy of hits.
