In 2017, the U.S. intelligence community assessed that North Korea had between 30 and 60 nuclear weapons (or weapons’ worth of fissile material) and could annually produce an additional seven to 12 weapons. While the Yongbyon reactor was offline, production would have decreased; however, resumed reactor operations will presumably return nuclear production to 2017-2018 levels. Since 2017, North Korea demonstrated significant improvements in its ability to target South Korea, Japan, and the continental United States with nuclear weapons. That year, Pyongyang conducted three intercontinental ballistic missile test launches, as well as a hydrogen (thermonuclear) weapon explosion at least 10 times as powerful as the Hiroshima and Nagasaki bombs. | In 2017, the U.S. intelligence community assessed that North Korea had between 30 and 60 nuclear weapons (or weapons’ worth of fissile material) and could annually produce an additional seven to 12 weapons.
