A new facility close to Pyongyang International Airport is certainly linked to North Korea’s expanding ballistic missile program, based on a report from a Washington-based think-tank.

CSIS Satellite Image Shows North Korea Building Missile Program Facility Near Pyongyang Airport

The Center for Strategic and International Studies (CSIS) cited industrial satellite imagery it says reveals the facility and nearby underground construction have the capacity to accommodate North Korea’s largest intercontinental ballistic missiles (ICBMs) that experts believe are capable of strike anywhere in the U.S.

The facility has been under construction since 2016, and contains a lot of notable features, along with an unusually large covered rail terminal and buildings that are linked by drive-through access, according to the CSIS report, revealed Tuesday. The facility is also comparatively close to ballistic missile component manufacturing plants in the Pyongyang area.

The North Korean embassy in Beijing couldn’t immediately be reached for comment on the report.

When asked in regards to the report at a regular briefing in Seoul Wednesday, a spokesperson for South Korea’s Unification Ministry stated it would be inappropriate to comment.

Negotiations aimed at dismantling North Korea’s nuclear and missile programs have been at a standstill after working-level meetings with the U.S. collapsed in 2019.

In 2018, North Korea stated it shut its Punggye-ri nuclear check site, and last year it offered to dismantle its Yongbyon nuclear complex in return for the revocation of five vital U.N. resolutions throughout a failed summit between chief Kim Jong Un and U.S. President Donald Trump in Vietnam.
