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.

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.
