March 3, 2021 Andrew Weston-Dawkes Director, Office of Classification US Department of Energy Dear Dr. Weston-Dawkes: This is a proposal for declassification pursuant to 10 C.F.R. 1045.20 regarding information classified under the Atomic Energy Act. We request that the Department of Energy and the Department of Defense authorize the declassification of the size of the U.S. nuclear stockpile and the number of weapons dismantled as of each of the following dates: 30 September 2018 30 September 2019 30 September 2020 As you know, our previous requests for declassification of stockpile information in these years were denied, even though similar data for all prior years have been declassified. However, we believe that changed circumstances justify revisiting the issue and declassifying the requested data. Specifically: 1. The President has called upon agencies to adopt "the highest standards of transparency." In a February 4, 2021 National Security Memorandum on "Revitalizing America's Foreign Policy and National Security Workforce, Institutions, and Partnerships" (available on the White House website here), the President wrote: "In a democracy, the public deserves as much transparency as possible regarding the work of our national security institutions, consistent with legitimate needs to protect sources and methods and sensitive foreign relationships. The revitalization of our national security and foreign policy workforce requires a recommitment to the highest standards of transparency." By terminating the annual disclosure of stockpile information, the prior Administration retreated from "the highest standards of transparency" that previously prevailed. Restoring such disclosure is consistent with the President's February 4 directive. 2. The New START Treaty has been extended. The prior refusal to disclose annual stockpile information coincided with a period of uncertainty regarding the status of the New START Treaty, which may have contributed indirectly to the denial of declassification. But with the recent extension of the New START Treaty, current circumstances more closely resemble those of the years 2010-2017 when the annual stockpile data was declassified. * * * Beyond that, we believe that the reasons that led to the previous declassifications of stockpile information are still valid. The benefits of declassification are substantial while the detrimental consequences, if any, are insignificant. As the first nuclear weapons state, the United States should strive to set a global example for clarity and transparency in nuclear weapons policy by disclosing its current stockpile size. Ambiguity is not helpful to anyone in this context. Far from diminishing security, a credible USG account of its stockpile size both enhances deterrence and serves as a confidence building measure. Even if other nations do not immediately follow our lead, stockpile declassification sends a valuable message. And at a time when the future of US nuclear weapons policy is under discussion in Congress and elsewhere, stockpile disclosure also helps to provide a factual foundation for ongoing public deliberation. For these reasons, we request that the Department of Energy and the Department of Defense declassify and disclose the number of nuclear weapons in the U.S. stockpile and the number of weapons dismantled at the end of each of Fiscal Years 2018, 2019, and 2020. Thank you for your consideration.
