The number of US nuclear weapons, including those in active status as well as those in long-term storage, stood at 3,750 as of September last year, the State Department has revealed. That is down from 3,805 a year earlier and 3,785 in 2018.
The Biden administration decided to disclose the number of nuclear weapons in its stockpile in a reversal of Trump administration policy, saying this would aid global efforts to control the spread of such weapons.
As recently as 2003, the US nuclear weapon total was slightly above 10,000. It peaked at 31,255 in 1967.
The last time the US government released its stockpile number was in March 2018, when it said the total was 3,822 as of September 2017.
That was early in the Trump administration, which subsequently kept updated numbers secret and denied a request by the Federation of American Scientists to declassified them.
“Back to transparency,” said Hans Kristensen, director of the Nuclear Information Project at the Federation of American Scientists. He said the Biden administration was wise to reverse the prior administration’s policy.
Kristensen said disclosing the stockpile number would help US diplomats in arms control negotiations and at next year’s Nuclear Non-Proliferation Treaty conference, which will review the disarmament commitment made by nuclear powers who are treaty signatories, including the United States.
The Biden administration is conducting a nuclear weapons posture and policy review that is expected to be completed early next year.
At the Conference on Disarmament last February, Secretary of State Antony Blinken said: “President Biden has made it clear: the US has a national security imperative and a moral responsibility to reduce and eventually eliminate the threat posed by weapons of mass destruction.”
