Declassification of Nuclear Warhead Build Rate Sought

The Federation of American Scientists this week petitioned the Department of Energy to declassify the annual rate at which the United States built new nuclear weapons throughout the cold war.

“The proposed declassification would enrich public understanding of the historical development of the U.S. stockpile. Disclosure of the actual build rate per year would add a dimension to the cold war historical narrative and bolster transparency in nuclear policy,” the FAS request said.

Total annual build rates have previously been declassified for the years 1945 through 1961.

The last completely new nuclear weapon in the U.S. arsenal was assembled on July 31, 1990, according to Stephen I. Schwartz of the Middlebury Institute of International Studies at Monterey.
