I can see how they would be rather upset about a radar that can observe the airspace over Chengdu from Taichung.

Edit: apparently they have an ABMD UHF radar in Hsinchu with comparable range. Should've went to see that instead of the science park ...
It's the long range of the THAAD missiles that will be a change to the status quo.

i personally wouldn't get too close to the radars, IIRC security is tight there.

I think you mean the radar. The missiles themselves have an estimated range of 200km but the radar is supposedly able to peer 1,000 km, which is still far short of Chengdu at 1,800km but still quite far.

I'm not trying to give you a hard time; it's just that it's hard for me to believe that someone would rather scale an entire jet around an existing radar size just to avoid scaling a radar up or down a bit to match the rest of the jet.

Even a small change costs time and money to design and debug. If you're short on time or money or both, then an existing and proven system becomes a valuable proposition.

Need photos of typical landing beaches and flatplains of Taiwan.
I am not ready to outright call it too heavy.

On the other hand, incredible mobility and protection disparity between two vehicles will count.


It isn't exactly "rip", but its FCS:missile combination actually predated the bird by full decade.
In its final form, AN/AWG-9+AIM-54 it was originally developed for F-111B.
"volumous" nose of the F-14, by far the largest in its generation, was forced by this radar.
Basically, the whole bird was the smallest possible interceptor with this radar.

The beaches aren't the problem, the problem is driving from the inland staging area. The tanks will have to drive across farmland, as staying in the roads is a very bad idea.

I would believe that if they were designing a budget fighter but a premier 5th gen fighter? The costs to time and money would be far less to scale a radar than to scale the rest of the jet. One thing is for sure; the Chinese did not size the J-20 around a Flanker radar in order to save the time and costs of adjusting the number of T/R modules. If there was any benefit that would result from a change in radar aperture, they would have done it.

the missiles can credibly threaten MRBMs.
Well that's what their designed for but China still has that huge numbers advantage to overwhelm them and the missiles have jamming and avoidance capabilities of their own.

This radar (AN/TPY-2) is designed to search and track ballistic missiles, which tend to fly very high. In its search mode, it has an estimated (and quoted) range of 3000km against a 0.1m2 RCS target, or even more against a larger cross section. That radar in South Korea is peeking quite deep into China.

The radar in Hsinchu is actually a PAVE PAWS AESA derivative, which outperforms the AN/TPY-2 in most aspects.

Is there a source that says that it was the radar that forced the F-14 to be big?
Radar:fcs:missile was wanted by the navy, since it was the only system of this kind to provide nevessary capabilities. Necessary capabilities included range&power for very heavy jamming, expected in this mission.
Navy had neither time(f-111b just failed, Soviet missile carriers were rolling off production lines like hot cakes) nor money or any motivation to develop a new system again.
Radar forced radome to be big(unusually big for tandeam-seated fighter of this size).
Keeping this radar with necessary loitering/climb/dash performance and number of missiles(4-6 phoenixes were big boys) made everything else big as well.

So is there a source or an article that that's how it actually went or did you make the assumption based on these observations? From what I know, if you have time to build a jet, you have time to tweak the T/R modules on an existing radar design.

Edit: I forgot not everything is AESA with T/R modules cus we were talking about J-20. See below

Thanks for the info; didn't know that. China better get its hypersonic missiles on this radar first thing in the event of a conflict.

But don't only AESA radars have T/R modules? Maybe for a mechanical radar it is much more difficult to scale down in size without total re-engineering.
