Chinese AEW ISR and Special Mission Aircraft

[RajaBaja]

I guess they want an even larger aperture.

Unlike older generation rotating radome, AESA radome does not need to rotate constantly to provide beam sweep. AESA rotating radome only need to rotate to orient it's aperture to face primary threat.

Instead of thinking it as rotating radome of old, think of it more like a balance beam radar that can rotate on it's own without having the plane change attitude.

The point is still the same, why? When a 3 fixed AESA with much less mechanical capability gives better or the same results, why add mechanical systems to it? The only valid question is that they found better capability in rotation than fixed. But the answer might only come from someone who has seen KJ-500 and other AEW platforms work. Until then it's all guess work. But it's definitely a capability issue. Otherwise you don't go back.

You've answered your own question. There're a bunch of pros and cons and trade-offs, obviously they deemed the added mechanical complexity is worth paying for the added capability from larger aperture, reduced array count from three to two and added flexibility to be able to point the arrays most potent orientation to threats.

That's fine. But that doesn't answer my question. I wanted technical, capability details on WHY the Chinese are going back to older technology / process when the world is moving away from rotational rotodome to a fixed 3 planner AESA design, that are easy to manage, cover longer ranges and less complex for maintenance, give more space inside the aircraft, etc.

The trade off must be considered worth it.

An interesting scenario would be a fleet of KJ-3000 flying from bases along the Indian-Chinese border, just 100 km north of Uttarakand and Himachal Pradesh. How far into India could they see? Could that data be relayed to allow CEC engagements (as was done in the May engagements between the PAF and IAF) or at least give early warning to the PAF if not weapons tracks.

This is a simple problem，the dual band radar aperture rotating within a disk of equal size on both sides can be larger, more powerful, and have a wider frequency band, providing better detection capabilities for stealth fighter jets.The drawbacks of this design certainly exist, but it has become insignificant in the system of multiple early warning aircraft cooperating to detect low RCS targets in order to deal with fifth generation aircraft, because three to four early warning aircraft will be deployed simultaneously in one combat direction on the battlefield to ensure control of the air situation.
PS: Don't rely solely on individual early warning aircraft to effectively detect enemy fifth generation aircraft, even if it's the Su-57. Once you have fifth generation aircraft in the future, you will deeply understand this principle

Guys ... almost each of these deleted posts was an insult and even more a stupid post derailing this thread! Take this as a clear warning and anyone who cannot hold his horses and posts another such insult, will face a ban without any further warning!

oh lighten up andy, a bit of fun never hurt anyone ;p

Fun yes - even fun is admittedly not a typical German feature - but posting - but posting disfigured people to each other as proof of something whatever is certainly
a) off-topic and
b) more of an insult!

So let's just leave it at that...

A follow on to this.

Some references say the E-7 Wedgetail can fly at 30,000 feet and has a max radar range of 850 km, with its 10.8 meter long radar. Some references claim the KJ-3000 can see out to 1000 km, with its 12-13 meter long radar.

In a time of heightened tensions a Chinese carrier battle group were in the North Arabian Sea with a KJ-600 patrolling near Karachi (similar to the 2002 French carrier battle group patrolling there during Operation Parakram) and a KJ-3000 flying west of Mount Kailash, could conceivable give the PLAAF/PLAN a solid picture of a large part of western India. Cueing by an expanded series of Chinese OTH radars in Tibet and Xinjiang to watch the Chinese SLOCs in the Indian Ocean, and Chinese imaging satellites that can following individual aircraft (after being cued), India seeing this could be deterred to some extent.

Why posting exactly the same video just from another X-account?

So far clearest image of a KJ-3000 prototype - here number #7821 - in flight.
