 Chinese nuclear C3 capabilities are centered around fibre-optic and satellite-based communication networks, replacing older radio command networks that made up the-then Second Artillery's C3 infrastructure before the 1990s.While historically Chinese nuclear missile forces had to launch from pre-prepared sites, the newest generation of nuclear-capable missiles (the DF-26 and DF-31AG) have been seen deploying to, and launching from, unprepared sites in exercises.This would corroborate reports that PLARF communications regiments are being trained in the ability to set up telephone and command networks "on-the-fly".
