Here's What You Need to Remember: In recent months North Korea has also unveiled several new ballistic missile systems including a new variant of submarine-launched ballistic missile and a new intercontinental ballistic missile.

North Korea is continuing to engage in activities related to its nuclear weapons and ballistic missile programs. Satellite imagery analysis conducted by the Center for Strategic and International Studies has found signs of renewed activity at North Korea’s Yongbyon Nuclear Research Center.

These images reveal that the facility’s Radiochemistry Laboratory, the associated thermal plant, and the centrifuge plant restarted activities at some point in early March. Little activity in recent months and years has been observed at the Radiochemistry Lab, and it is difficult to determine with any degree of certainty precisely what is taking place at the facility, analysts believe it may indicate a renewed plutonium reprocessing campaign or, at the very least, a demonstration or reminder that such a campaign could be undertaken at some point in the future. Such a campaign would add to North Korea’s inventory of fissile material needed for the production of nuclear weapons.

Experts have estimated that North Korea likely possesses somewhere between 20-60 nuclear weapons. Others have projected that by 2027 North Korea could possess as many as 151 to 242 nuclear weapons. 

The evidence of possible North Koran plutonium reprocessing at its Yongbyon facility emerged just prior to the Biden administration’s announcement that it had completed its review of U.S. North Korea policy. Specific details about the new policy remain scarce, but the administration has described it as a phased approach in pursuit of North Korean denuclearization centered around partial sanctions relief in exchange for North Korea steps towards denuclearization. Officials involved in the policy review process stressed that the Biden administration’s policy is distinct from the policies of previous administrations, which they acknowledged had failed to prevent continued growth of North Korea’s nuclear weapons and ballistic missile arsenals.

Experts have suggested that the repeated focus on denuclearization is largely to blame, arguing that the United States should instead adopt a policy aimed at addressing the threat posed by a nuclear armed North Korea including by negotiating a freeze on plutonium and uranium nuclear activities at the Yongbyon facility.

North Korea has also demonstrated continued progress in the development of its ballistic missile capabilities. In March, North Korea test fired what appears to have been a new variant of an already highly advanced short-range ballistic missile system. In recent months North Korea has also unveiled several new ballistic missile systems including a new variant of submarine-launched ballistic missile and a new intercontinental ballistic missile.

North Korean leader Kim Jong Un has stated that North Korea will continue to develop its strategic weapons capability as well as pursue other military capabilities such as tactical nuclear weapons.
