“As of September 2020, the U.S. stockpile of nuclear warheads consisted of 3,750 warheads. This number represents an approximate 88 percent reduction in the stockpile from its maximum (31,255) at the end of fiscal year 1967, and an approximate 83 percent reduction from its level (22,217) when the Berlin Wall fell in late 1989,” the fact sheet said.
The US dismantled 184 warheads in 2020 according to the fact sheet, bringing the total number of warheads dismantled since 1994 to 11,683.
The State Department added that increasing the transparency of states’ nuclear stockpiles is important to nonproliferation and disarmament efforts, including commitments under the Nuclear Non-Proliferation Treaty.
