Stephen Trimble over at the The DEW Line spotted this photo apparently showing the weapons bays on the J-20.
This is not the first time I have posted on the J-20's weapons bays, but in this photo there are some inconsistencies. 1. the PL-9 on the side is larger than the PL-12s in the centerline weapons bay. 2. The PL-12s in the centerline bay appear to have fins overlapping. 3. This appears to be a plastic model that you buy in a hobby shop, and not a very accurate one at that.
If this is a model then it does not necessarily show the J-20's true payload, as that would be top secret in China.
