Official media of the Democratic People’s Republic of Korea (DPRK) reported on 16 September 2021 that a newly established “railway-borne missile regiment” launched two ballistic missiles from a rail-mobile launcher on 15 September 2021. This is the first time the DPRK has revealed this ballistic missile basing mode, a mode known to have been adopted only by the Soviet Union/Russia.
Conclusions: This latest development shows that the DPRK leadership is trying to improve the survivability of its nuclear arsenal, and in so doing advancing its preemptive and counter-strike capabilities. The efforts by the DPRK and the ROK to advance missile strike capabilities manifest the ongoing arms race on the Korean Peninsula. The risk of possible conflict escalation continues to be present, if not increasing.
