Actually, the Russians do have some new tech that has appeared since the F-22 was designed. As the Australians discovered, an American stealth aircraft *can* be seen at range by using a radar array with multiple transceivers spread out over a rather large area. Russian anti air batteries have taken that idea and run with it - they can now datalink into a virtual very large radar array that can see stealthy aircraft. The question is whether they’ve developed the tech to the point where it can localize a stealth craft to the degree of getting a missile lock or if it’s only good enough to tell you a stealth craft’s general location.
Keep in mind as well that the exercises have shown that the F-22’s biggest advantage is mostly that it operates closely with AWACS and can perform its task without any betraying emissions. Without AWACS, it has problems. And Russia has AWACS killing missiles now.
"WILL BE SHOT DOWN" ain't as certain as that which is being claimed here, is all I'm saying. What is certain, is that a Russian pilot firing on an American, or NATO pilot, is a game changer for the world.
