I don't think this thing is particularly necessary, and the PLA would disclose any relevant information.
The PLA's biggest move right now is to continue expanding and filling those "wind farms."
When you have 600 DF-5C with HGV MIRVs, is it truly necessary to expend such effort on FOBS?
It is abundantly clear that one can never have too many good things, and no nation would ever complain about possessing too many powerful weapons. This is especially critical for the PLA to recognize in the face of the severe pressure currently exerted by the United States in aerospace domains. Even though the PLA now commands formidable strategic nuclear strike capabilities and hypersonic weapon systems, this does not mean it can rest on its laurels. We must acknowledge the formidable R&D capabilities demonstrated by some U.S. private enterprises. While the U.S. military itself may be temporarily lagging, SpaceX's engineers certainly won't grow complacent. Furthermore, while the PLA may temporarily focus solely on establishing an area denial defense system within the Asia-Pacific region, this does not preclude the PLA from eventually developing an urgent need for global strike capabilities. Given that competition with the United States will inevitably be comprehensive, we cannot place excessive faith in other regional powers to reliably fulfill their “tasks.”
