Impact of study on US military’s F-22 fighter jet could be great given range of its air-to-air missiles and required radius for ground bomb attacks, says team.
I don’t think this work is even that surprising, which is perhaps the surprising part to most people. Fusing information from a network of radars has always been the Achilles heel of stealth aircraft. It’s just that radar fusion at a country-level scale hadn’t really been demonstrated before.
The US is happy to fly an F-22 around willy nilly in air shows and whatever /s
The real answer is that the J-20’s RCS is probably similar to the F-22 and they realized that the J-20 is vulnerable to this. This has been a known problem with stealth technology for forever, so it’s really more of a deterrence. China really doesn’t want a war, which is why their Navy is so heavily oriented towards coastal (defensive) operations rather than blue water (offensive/power projection) operations.

I’m sitting here trying to figure out where the Chinese got an F22 to test their study results on.

Sensor fusion is wicked hard though. At the sensor level and the track level it’s a huge pain, especially on something maneuverable.
Engineering problem.
