• Located approximately 27 kilometers from the China-North Korean border, the Sinpung-dong Missile Operating Base is an undeclared ballistic missile operating base in North Pyongan Province. > - The base is one of North Korea’s approximately 15-20 ballistic missile bases, maintenance, support, missile storage, and warhead storage facilities which North Korea has never declared. This is the first in-depth open-source study confirming the base.
• Preliminary analysis suggests that the base likely houses a brigade-sized unit equipped with a total of 6-9 nuclear capable Hwasong-15 or -18 intercontinental ballistic missiles (ICBM), or an as yet unknown ICBM, and their transporter-erector-launchers (TEL) or mobile-erector-launchers (MEL). These missiles pose a potential nuclear threat to East Asia and the continental United States.
• Current assessments are that during times of crisis or war, these launchers and missiles will exit the base, meet special warhead storage/transportation units, and conduct launch operations from dispersed pre-surveyed sites.
• The Sinpung-dong Missile Operating Base and the other missile bases within North Korea’s strategic ballistic missile belt (including other undeclared bases like the Hoejung-ni, Sangnam-ni and Yongnim Missile Operating Bases) represent the primary components of what is presumed to be North Korea’s evolving ballistic missile strategy, and its expanding strategic-level nuclear deterrence and strike capabilities.
• The Sinpung-dong Missile Operating Base is not known to have been the subject of any denuclearization negotiations previously conducted between the United States and North Korea.
