December 13, 2019, by Joseph S. Bermudez Jr. and Victor Cha— The Magunpo Solid Rocket Motor Test Facility is located a few kilometers west of the Hamhung-Hungnam area and along the east coast of North Korea. December 6 imagery shows minor activity at the facility, including the presence of a small truck and some crates. Although no recent test appears to have taken place (i.e., absence of scarring in the exhaust deflector and healthy surrounding vegetation), the facility appears to be well-maintained and ready for solid rocket motor testing at any time. A successful test of solid fuel propellant engine, particularly at the east test stand, would denote another major advancement in survivable nuclear weapons capability, and would presumably also be designed to put additional pressure on the U.S. to make concessions in negotiations.

December 11, 2019, by Joseph S. Bermudez Jr. and Victor Cha— On December 7, North Korea conducted what it described as a “…very important test at the Sohae Satellite Launching Ground.” Satellite imagery in the days leading up to and after the test clearly shows that this was a rocket engine test at the vertical engine test stand at Sohae. This test was most probably of a liquid-fuel rocket engine as only liquid-fuel rocket engines have previously been tested here, while large solid rocket motors have been tested at the Magunpo Solid Rocket Motor Test Facility on the east coast and elsewhere. Whether the liquid-fuel rocket engine was an existing model or a new one is unknown.

December 4, 2019, by Joseph S. Bermudez Jr. and Victor Cha— There is no evidence that the “newly built submarine” inspected by Kim Jong-un on July 23, 2019 has been launched. While many media sources have described this new submarine as an imminent threat, it is more accurate to describe it as an emerging threat. The large canopy constructed during late-August and early-September that conceals much of the submarine dock precludes confirmation that the existing SINPO-class experimental ballistic missile submarine (SSBA) is present.

October 9, 2019, by Joseph S. Bermudez Jr., Victor Cha and Dana Kim— The October 2, 2019 Pukguksong-3 submarine-launched ballistic missile (SLBM) test launch has raised concerns over the forthcoming launch of North Korea’s first true ballistic missile submarine (SSB) as described in the Beyond Parallel Snapshot, which was published the same day.

October 2, 2019, by Joseph S. Bermudez Jr., Victor Cha and Dana Kim— Around 7:11 am on October 2 (KST), North Korea launched what may have been a submarine launched ballistic missile (SLBM) from waters northeast of the Wonsan, Kangwon Province area into the sea between Korea and Japan. The last Beyond Parallel report on the Sinpo South Shipyard indicated the possibility of ongoing preparations for a launch.

September 6, 2019, by Joseph S. Bermudez Jr. and Victor Cha— New CSIS Beyond Parallel imagery shows the undeclared Kumchon-ni missile operating base. This is the first comprehensive public description of the base. During wartime, it is reportedly tasked with striking southern Japan and, to a lesser degree, throughout South Korea.

August 28, 2019, by Joseph S. Bermudez Jr. and Victor Cha— New Beyond Parallel imagery (August 26, 2019) of Sinpo South Shipyard suggests circumstantial evidence of the construction of a new ballistic missile submarine and preliminary evidence indicates possible preparations for a test...

June 20, 2019, by Joseph S. Bermudez Jr. and Victor Cha— Satellite imagery of the No. 112 Factory (sometimes identified as the January 12th Factory) located in Kusong, North Pyongan suggests that North Korea is constructing a monument memorializing its first successful Hwasong-12 intermediate range ballistic missile (IRBM) launch on May 14, 2017.

May 9, 2019, by Joseph S. Bermudez Jr. and Victor Cha— Located 150 kilometers north of the DMZ, North Korea's Yusang-ni missile operating base is one of the more recently constructed Strategic Force missile operating bases. There has been almost no open source information about this base until this study.

April 10, 2019, by Joseph S. Bermudez Jr. and Victor Cha— On the eve of President Trump’s summit with ROK president Moon Jae-in, commercial satellite imagery acquired on April 7 shows that, although not conclusive, North Korea may be preparing for a parade to honor Kim Il-sung’s birthday (April 15) or KPA Foundation Day (April 25).
