Stealth:
>bodykit that can be rendered on a generic $200 gpu to increase radar deflection and aabsorption properties
>"stealth engine" just means slightly underpowered engine to reduce ir with pointy bits for radar absorption
>stealth paint is just metal shavings in spray paint
Anyone can make a stealth jet

Why can't China/Russia then?

>metal shavings in spray paint

Carbon nanotubes (available on amazon in bulk) mixed with shredded VHS tape applied as a water proofing on the canvas skin silly.

I guess making a plane that passes your radar waves casting tests while having the correct aero is not so simple. It's an optimization problem where the two objective functions are not compatible. The hard part I guess would be to code the program that can create the proper 3d shape while accommodating the fuel, engines and everything else inside. Constrained generative design is not new but still, not easy + your electromagnetic waves simulation and aero simulation probably needs to be top notch

Let's go full frogtard.
Yes anyone can do an stealth airframe, regardless if it's easy to maintain, but that's just 30-50% (ass figures) of a stealth fighter. The avionics also must be LPI and being to sense the environment to stay undetected.
In fact by bad definition a lot of US fighters were 'stealth' because they could degrade enemy radars with EW enough to not being tracked or locked-on.

If its possible from first principles its possible for everyone to do it given they're not drooling retards.

can be iteratively designed digitally

>can be iteratively designed digitally
empty words

of course. it's just that not many nations have military aviation industries.

for most, it's better to go with stealth missiles (storm shadow, x-69, jassm and whatever), since these come from munitions industries and they will have a far less rcs than any stealth bird.

They're just tiny wings. If you can get the rest of the body to be stealth the avionics is trivial.

So biplanes designed for ground hugging and stealth.
