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.

Recent satellite imagery from November 2019 shows the presence of four specialized railcars that have been associated with the movement of radioactive material in the past. The last observed movement of these railcars by Beyond Parallel was in April 2019. It is unclear whether the railcars are being used for the outbound shipment of irradiated liquid or solid waste, disassembled but contaminated equipment or the movement of fissile material to facilities outside the Yongbyon area. A less likely alternative is the inbound shipment of radioactive material from a facility outside the Yongbyon area.

This Living History interview features former South Korean minister of foreign affairs and trade, Song Min-soon. Song was director general for North American affairs and chief delegate during the six-party talks in 2005. He played a key role in the multilateral denuclearization agreement with North Korea, involving the United States, Japan, South Korea, China, and Russia, achieved in September 2005.

Collected 14 months after the image provided in Part 5 (November 21, 1968) this March 17, 1970 KH-4B image of the Yongbyon Nuclear Research Center shows continued expansion within the village of Sang-dong, minor improvements in the operations, administration/laboratory and support areas, slowly continuing construction of the bridge across the Kuryong-gang and minor infrastructure improvements in the Pungang-ni area. Taken as a whole, these developments continue to indicate an ongoing first-phase construction project for the facility and very early infrastructure development efforts within a longer-term plan for future expansion.

Analysis of satellite imagery of the Punggye-ri Nuclear Test Facility acquired during 2019 and more specifically on September 23rd and October 9th, 2019 shows the facility in caretaker status, likely being maintained by security personnel. While there is no evidence of current efforts to restore any of the nuclear test portals, several observations lead us to believe the facility has not been permanently disabled and that the detonations in May 2018 are not necessarily irreversible.

Collected eleven months after the image provided in Part 4 (December 10, 1967) this November 21, 1968 KH-4B image of the Yongbyon Nuclear Research Center does not show any significant developments in the operations (with the IRT-2000 research reactor), support or administrative/laboratory areas. It does, however, show continuing development within the village of Sang-dong and the early stages of construction for a new road bridge across the Kuryong-gang in the Pungang-ni area that will connect the support area to the opposite side of the river. Taken as a whole, these developments represent both continuation of a first-phase construction project for the facility and the earliest infrastructure development stages within a longer-term plan for future expansion.

The Pakchon Uranium Concentrate Pilot Plant is one of only two declared and known uranium concentrate plants in North Korea (Pyongsan Uranium Concentrate Plant at Pyongsan is the other). This facility was used for Yellowcake production at least through the mid-1990s, and therefore would require inspection under any new U.S.-DPRK denuclearization declaration and agreement as it has not been subject to international inspection for over 25 years since IAEA visits to the site as part of the Full Scope Safeguards Agreement process in 1992.

Acquired almost two years after the image provided in Yongbyon Declassified Part III (February 11, 1966), this December 10, 1967 image of the Yongbyon Nuclear Research Center is one of the first acquired by the improved reconnaissance KH-4B. Among other improvements, the resolution of the newer KH-4B was 1.8 meters versus 2.7 meters of the earlier KH-4A allowing for considerably better image quality.

As the first sitting president in U.S. history to step into North Korea, Donald Trump’s action could be seen as a significant representation of the U.S. intention eventually to conclude a peace treaty... As the first sitting president in U.S. history to step into North Korea, Donald Trump’s…

Acquired seven months after the image provided in Yongbyon Declassified Part II (August 23, 1965) this 2.7-meter resolution image covers the Yongbyon area on February 11, 1966. While the general area remains primarily engaged in agricultural activity typical of rural North Korea during the 1960s, significant construction activity is observed at the nascent Yongbyon Nuclear Research Center and adjacent village of Sang-dong.
