Overview
- CSIS’s Beyond Parallel used July 11 commercial satellite imagery to confirm an undeclared missile operating base at Sinpung-dong about 27 km from China.
- The think tank assesses a brigade-sized force with six to nine nuclear-capable ICBMs and their mobile launchers is stationed there.
- Construction began around 2004, the base has been operational since roughly 2014, and imagery shows ongoing development.
- The facility has hardened underground structures and drive-through checkout bays, with launchers expected to disperse to pre-surveyed firing sites in a crisis.
- CSIS places the site within a network of roughly 15–20 undeclared missile and warhead facilities and says its proximity to China complicates potential strikes and presents a potential threat to East Asia and the U.S. mainland.
