Deino, you are not likely to see good numbers from now on.

Chengfei is kicking businesses out and building high walls, of course, not as high as the "Great Wall" along the US and Mexico border.

It is exactly for this purpose that drones were invented!

Interesting that Wiki number is very accurate ... it does say 5 production aircraft

What normally the Air Force would do to the prototypes? (in this case there are 8 prototypes of J-20)

Wondering how many J-20x PLAAF would order?

Also how many J-20 to be produced yearly ?

It has already been said the more accurate Henri K say i have posted 1st batch 40 units 2017 - 19

Or they may use HQ-9 to shoot those Phantom drones down.

The Chinese are not nearly so profligate.

They have purpose designed lasers for precisely this sort of contingency. The irony is one of those anti-drone lasers probably cost less than a Patriot missile.

Somehow I doubt even the Israelis would have been so wasteful if they weren't getting billions of free arms from the US every year.

China is the home of the modern high end civilian camera drone. Do you think it's a co-incidence not a single picture has been taken of any significant Chinese military installation by drones?

Not only would such places have hard and softkill countermeasures against snooping drones, to use one in such a way is a surefire way to get on Chinese internal security's radar. And they are very good at their job, just ask the CIA.

I have been looking at some old J20 pictures, and I wonder if the black diamonds on the cheeks and before the canopy might be heat release vents?

The current consensus of them being part of some kind of OE sensor has always struck me as unconvincing because of placement.

There is just no good reason to place them where they are if they were windows for OE sensors.

The nose area is the place on the plane where space is at its most premium. There is just no reason to put side looking EO sensors in that area when they would work just as well placed further back on the plane. Especially so on a stealth plane, where frontal RCS matters the most.

Heat release vents for the AESA OTOH, could only be placed on the nose directly behind the radar.

The reason for needing those vents may be that the J20 is, or plans to eventually use a GaN based AESA.

GaN is superior to current GaAs in every way except one - peak heat, mainly because of the much higher peak power capability of GaN.

I'm pretty confident those black diamonds are EO apertures. That is the same location the F-35's side facing EODAS apertures are placed as well.

And tbh I've never heard of a fighter with vents for their radars before. I don't know if a GaN AESA would even need a vent of any kind.
