    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.

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