I can't help but feel that they should have completed RCS testing long before rolling out the first production model...
seems that there are more than one facility.
How do you know this photo is NOT taken long time ago?
We see it now doesn't mean it is taken now.
It may not be RCS either. Could be everything from testing passive RF and other emissions to other signals work.
I don't understand how this RCS test work. in the 2013 photo, it's hard to see the aircraft, but in the 2015 photo, I can see the aircraft. So what's the different. The first photo shadow look like a long slim pylon, while the second has an aircraft like shadow. So can somebody explain what is these photos tell us?
The first picture shows only the pole stand.
The second picture has a J-20 full scale mock up mounted on the pole for testing purposes.
In other words the pole stand is fixed, but the J-20 mock up is removable.
Many aircraft, and stealth aircraft in particular undergo this type of testing.
Possibly, but from what I understand, dedicated RCS airframes are made for these purposes instead of static test fatigue airframes.
It makes sense to have dedicated RCS representative airframes instead of fully representative static test airframes, I think, given static test airframes will be much heavier and feature many internal structures which may not be required for RCS testing. And of course a static test airframe would be much heavier than a dedicated RCS representative airframe.
