It doesn't even make sense. Hypersonic missiles are good at being hard to take down themselves. But you don't need that to take down an aircraft. You need super sensitive radar systems, since the claim is that these aircraft reflect about as much energy as a bumblebee would.
61these aircraft reflect about as much energy as a bumblebee would.
That is truly amazing.
25Do note that the this claim comes from the same people who don't hand out any actual specs and always fly with an additional reflector. The latter makes it easy for radars to see them again. This is helpful in allied airspace, but it also makes it impossible to verify the claim.
Also note that modern radars are sensitive to how fast an object approaches (or leaves) the radar. Bumblebees don't break the soundbarrier usually, so it is possible to see these planes, but you do have to tweak your radar for it. (Hence why the US doesn't give specs.)

Buzzwords are all that matters.
Also, too much of a credible point.
12Most state of the art SAMs are technically hypersonic.
4Interesting. I did not know that!

It’s not that impressive… a bumblebee can emit the same small radar signature as well.

Maybe. Maybe not. Maybe fuck yourself.

OMG, scary news. Time to increase the defense budget again, I guess…
29Hypersonically it goes door-to-door knocking
"Any B-21's here? No, right then. On to the neighbors."19The article I read indicates China used a sim which means they have to guess at what the RCS of the b21 is. Further they shot down the simulated b21 with a hypersonic missile after they pretended to target something else then veered towards the b21, claiming the pilot wouldn't take evasive action based on it's initial trajectory.
So if China knows the RCS of the b21, the performance, and the pilot doesn't react to a missile targeting the b21, they can shoot it down.
17This is the equivalent of someone telling you exactly which Bullshido moves they would use if they were attacked by a professional MMA fighter.
9In a simulation where the only radar reflector is one simulated jet, and there is no real hardware, it's pretty easy to hit since the Pfa is effectively zero. In the real world, there's a thousand different things which will give some similar energy return and there's no simple way to filter that out without actually seeing the thing in real life.
Stealth isn't about zeroing the energy, it's about pushing it into an ambiguous state space where it cannot be distinguished from birds and shit.
5Doppler filtering will do alot to eliminate slow moving clutter sources but I have my doubts they can detect a 0.1 sq meter return much further than 20km.
Stealth uses many techniques to lower the return, shaping to stop direct returns to the source, mag ram (magnetic radar absorbing material) to absorb some of the energy and stop traveling waves at high frequency, and resistive cards or similar methods for low frequency which has sections of different resistivity that cause mini defractions instead of one large one.

I worked on the b-2 (has the same tech nearly). If you take a panel off to inspect anything or fix an issue the jet has to go to the paint shop to have the paint re-applied because its most of what makes it stealth. The paint absorbs radar.
6Lets find out, these things armed with nukes vs China and their "hypersonic" missile
4The most bat shit insane part of this is the missile absolutely cannot maneuver to intercept at hyper sonic speeds unless it's a nuclear warhead. In which case, yes we know you can down a plane with a nuke.
