Chinese claims they detect F-22 from 450 km away

Anything goes, as long as it is about the Lockheed Martin F-22 Raptor

During a talk holding in a research workshop, the chief scientist of the China's largest radar group, CETC, Dr Wu Jianqi, told the audience that China's anti-stealth radar is the world most advanced anti-stealth radar.

It solved all the tech difficulties that other countries failed to solve and the 4th generation anti-stealth radar CETC developed, their radar, is the world's only anti-stealth radar that can not only spot but also track and guide fire-control radar to attack enemy stealth aircrafts in a range of over 500 km.

During the talk, he give an example that their last generation anti-stealth radar track F-22 fighters in East Asia flying 450 km away.

And he told the audience China airforce now cover the entire China coastline with such highly advanced anti-stealth radar, such that US stealth fighters will be meaningless.

Can someone translate the slide?

So, is China going to stop the development of both the J-20 and J-31??? As everyone knows the F-22 is more stealthy than either of the aforementioned. Clearly, Stealth Fighters are no longer a serious threat.... :wink:

Are we really going to go through all this again? :bang: :bang:

Unless they found some way to bend the fundamental laws of physics I call male bovine excrement. Besides I take most claims by Chinese state run media with a grain of salt... as in pass the salt shaker and leave it here.

Or rather they tracked what they think was an F-22 from 450 km away
How did they confirm this by the way?
Did they call the contact?

Hey are you and F-22
Why yes I am an F-22 how did you know?

I suppose it's possible if the F22 still has Lunebergs fitted.

Very possible along with EFTs. Anyway, making a radar capable of tracking F-22 at those ranges is definitely not impossible. Just make a huge and very sensitive antenna and couple it with massive processing power. Problem is that it would be pretty vulnerable during war due to their massive size.

The Chinese obviously don't believe in OPSEC. :devil:

JORN was supposed to have detected B-2 flights, the trick though ultimately is that the X-band fire control radar on the missile has to track, it all ultimately comes down to that end puzzle. It's all very well spotting incoming but no good if you can't shoot them down.

The B-2 also possesses radar enhancement devices. Do we know they weren't deployed when they were "detected"?

I've also spoken to someone who inadvertently locked up a B-2 with an F-15E radar back in the 90s while it was on a test stand. The B-2 was landing and had it's gear down. He was testing the radar after a repair, saw a blip on the scope, locked it up, and within seconds the blip would disappear. He thought the radar was busted until he got a call from someone (I think it was the tower) to stop locking up the B-2 as it was forcing them to abort it's landings by engaging the defense mechanisms (no word on what that means).

I guess its safe to say that the "defensive mechanism" involved automatically closing down all doors and bomb bays.

Curious, would it be possible to emit a radio signal that looks like its painting a target or locking up on a target and broadcast that signal over a wide area. That way, all stealth aircraft with similar defensive mechanisms will be forced to automatically close down all their doors and weapons bays.

And from that story, it looks like there is no override switch.

If there is any truth to that it probably took about 3.2 seconds to implement a software fix. No way is an enemy going to be able to force B-2 bay doors to stay closed by broadcasting a signal.

I thought the same, no override for such an event sounds like a class A accident waiting to happen.

This same radar system just got pulverized by the Israelis at Damascus airport, Along with a couple of Russian tor m1.
