Speaking of which, an update:
Roughly translated:
Have a closer look at the older wheel chock:
View attachment 127552
And compare it with the newer wheel chock:
View attachment 127553
The older wheel chocks have 11 "blades", while the newer wheel chocks have 14 "blades". Also, the widening of the wheel chocks involved adding additional "blades" inwards (i.e. towards the center).
On one hand, this should confirm that the J-35s is indeed STOBAR-capable and will be capable of operating from Liaoning (and Shandong after her mid-life upgrade sometime in the future).
On the other hand, comparing the newer, wider wheel chocks at the PLAN NAU to the even wider wheel chocks on the Kuznetsov CV:
View attachment 127554
We can see that while each of the twin wheel chocks on the Kuznetsov are divided into two halves with 11 "blades" on each halves (i.e. 22 "blades" in total), such that the outer halves are used for the SU-33 while the inner halves are used for the MiG-29K - The newer, wider wheel chocks at the PLAN NAU are operated as a whole.
This should mean that spacing between the rear undercarriages of the J-35 is pretty wide. Not as wide as the J-15, but certainly nowhere as narrow as the MiG-29K.
