What's the point of hiding after it has been seen multiple times?
To, for example, prevent someone from taking a close-up photo of it while scaling the fences of SAC. This literally happened like 3 days ago with the J-36 (as well as with the J-35 back in 2022) so their caution is well warranted imo
Regarding the satellite thing, any info on the J-XDS is valuable at this point and if making a glorified shed on wheels can deny the adversary information like how it’s serviced, where the electricity and gas is plugged in, how many ground crew, how the cockpit opens, etc, then by their Shaokao and their local beer “Xuehua” they will see it done.
