Updated Nuclear Stockpile Figures Declassified

The size of the U.S. nuclear stockpile as of September 30, 2015 — 4,571 weapons — and the number of U.S. nuclear weapons that were dismantled in FY 2015 — 109 of them — were declassified and disclosed last week.

The latest figures came as a disappointment to arms control and disarmament advocates who favor sharp reductions in global nuclear inventories.

The new numbers “show that the Obama administration has reduced the U.S. stockpile less than any other post-Cold War administration, and that the number of warheads dismantled in 2015 was lowest since President Obama took office,” wrote Hans M. Kristensen in the FAS Strategic Security blog.

But precisely because the new disclosure casts an unflattering light on the Obama Administration, it also represents a triumph of transparency. Since it is at odds with the Administration’s own declared agenda, the release enables the press and the public to exact a measure of accountability.

“The new figures […] underscored the striking gap between Mr. Obama’s soaring vision of a world without nuclear arms, which he laid out during the first months of his presidency, and the tough geopolitical and bureaucratic realities of actually getting rid of those weapons,” wrote William J. Broad in the New York Times on May 26.

“Obama calls for end to nuclear weapons, but U.S. disarmament is slowest since 1980,” as a Washington Post headline put it on May 27.

News stories credited the Department of Defense for the “annual public release” of the stockpile information. But it is a bit more complicated than that.

The nuclear stockpile size was classified as “Formerly Restricted Data” (FRD) under the Atomic Energy Act. As such, it had to be cooperatively declassified by both the Department of Defense and the Department of Energy. And the declassification of FRD does not occur regularly or spontaneously.

“It is not the policy of the DoD/DOE to release such numbers automatically,” said Andrew Weston-Dawkes, the director of the DOE Office of Classification. Instead, consideration is given to declassification of specific information as it is requested. In this case, release of the 2015 stockpile figures was requested by the Federation of American Scientists in an October 2015 petition.

“The declassification of stockpile numbers was a direct result of your request for the information,” Dr. Weston-Dawkes wrote in an email. “Your request was reviewed by the DoD-FRD working group and in turn approved by the DoD and the DOE.”

Until the Obama Administration declassified it for the first time in 2010, the current size of the U.S. nuclear arsenal had never been officially made public. (Historical stockpile numbers up to 1961 were released in the 1990s.)

Columnists and commentators are in the habit of mocking President Obama’s promise that his would be the most transparent Administration in history. But when it comes to nuclear stockpile information, that promise has been fulfilled.
