March 25, 2019, by Joseph S. Bermudez Jr. and Victor Cha— Satellite imagery acquired on March 21, 2019 and over the past six months indicates that the No. 17 Explosives Factory near Hamhung is active. While no significant changes have occurred with its infrastructure during this period, the factory was expanded during 2012 with the construction of a large mixing/casting facility capable of producing large solid-propellant rocket motors for ballistic missiles.

March 19, 2019, by Joseph S. Bermudez Jr. and Victor Cha— While recent activity at the Sohae Launch facility appears to have returned it to operational status after DPRK dismantlement measures earlier in the summer, there has been no activity of significance at the vertical engine test stand or launch pad since early March.

March 9, 2019, by Joseph S. Bermudez Jr. and Victor Cha— Commercial satellite imagery acquired on both March 6 and March 8, 2019, shows that North Korea has continued preparations on the launch pad and the vertical engine test stand at the Sohae Launch Facility. Based on past practices, these activities could be consistent with preparations for the delivery of a rocket to the launch pad or engine to the test stand; or, they could be North Korean coercive bargaining tactics after the failed Hanoi summit.

March 7, 2019, by Joseph S. Bermudez Jr. and Victor Cha— Commercial satellite imagery acquired March 6, 2019—four days after the previous image—shows that North Korea has essentially completed the rebuilding of both the rail-mounted transfer transfer/processing structure on the launch pad and the vertical engine at the Sohae Launch Facility.

January 30, 2019, by Joseph S. Bermudez Jr. and Victor Cha— As of January 20, 2019, commercial satellite imagery of the Sohae Satellite Launch Facility (Tongchang-ri) shows that no new dismantling activity has occurred at the vertical test engine stand or the rail-mounted processing building since August 2018.

January 21, 2019, by Joseph S. Bermudez Jr., Victor Cha and Lisa Collins— Located 212 kilometers north of the DMZ, Sino-ri is an operational missile base that houses a regiment-sized unit equipped with Nodong-1/-2 medium-range ballistic missiles (MRBM). It is one of the oldest of approximately 20 undeclared missile operating bases and is reported to serve as the headquarters of the Strategic Rocket Forces Nodong missile brigade. It may have also played a role in development of the newest generation Pukkuksong-2 (KN-15) ballistic missile first tested or unveiled by North Korea on February 12, 2017.

June 11, 2018, by Victor Cha— There has been much criticism of President Trump's impulsive actions and the unconventionality of the Singapore Summit. However, absent a complete breakdown of the encounter between the leaders, the summit is likely to produce a negotiation process between the United States and North Korea that will implement the mandates laid out by the leaders on denuclearization, security assurances, and a peace process on the Korean peninsula.

April 23, 2018— On Saturday April 21, commercial satellite imagery from the Sohae Satellite Launching Station indicates minimal to no activity ahead of the inter-Korean summit. While dwindled ground activity could be attributed to the fact that images were taken during a weekend, the absence of any parked vehicular traffic and human activity suggests compliance with the leadership’s declaration, coming out of the Third Plenary of the Central Committee of the Workers' Party.

March 2, 2018, by Victor Cha and Marie DuMond— Reports of ubiquitous celebrations of nuclear weapons accomplishments stand in stark contrast with a new micro-survey commissioned by Beyond Parallel of North Korean citizens. Conducted throughout the summer and fall of 2017 with a cross-section of North Korean citizens, the vast majority of North Korean respondents did not have a positive attitude toward their country’s nuclear weapons program.

November 22, 2017, by Marie DuMond— On November 22, predictive signals by Predata/CSIS Beyond Parallel indicate there is an elevated likelihood of a North Korean WMD activity in the next 14 to 30 day windows. The likelihood of WMD activity in the coming weeks is tempered by the fact that, historically, North Korea has not conducted many tests in the November and December timeframe.
