Index of Nuclear Data


With the publication of the first volume of the Nuclear Weapons Databook in 1984, NRDC established itself as the preeminent supplier of comprehensive and accurate data about nuclear arsenals. This was followed in 1987 by publication of Volumes II and III concerning U.S. Nuclear Warhead Production, by Volume IV in 1989 on Soviet Nuclear Weapons, and by Volume V in 1994 on British, French, and Chinese Nuclear Forces. Since 1985, NRDC has additionally coauthored chapters and provided statistical nuclear forces tables in annual editions of the SIPRI Yearbook published by the Stockholm International Peace Research Institute (SIPRI). In 1987, NRDC also began writing the "Nuclear Notebook" section in each issue of The Bulletin of the Atomic Scientists to supplement and update information in the Databooks. NRDC data is also used as a source for tables in editions of the annual The Military Balance published by the International Institute for Strategic Studies (IISS). NRDC is also called upon repeatedly to supply data for tables, graphs, and maps to accompany articles in newspapers and magazines.

No examination of recent nuclear data would be complete without looking at the 1994 DOE "Declassification of Certain Characteristics of the United States Nuclear Weapon Stockpile" (located at http://www.osti.gov/html/osti/opennet/document/press/pc26.html ). The DOE site includes the following tables: Joint DOE/DOD declassification of information on the nuclear stockpile, including total megatonnage (1945-1994); the total number of nuclear weapons in the stockpile (1949-1961); total number of weapon builds by year for weapon systems fully retired; total number of weapon retirements (1945-1989); and the number of disassembled weapons from 1980-1994.

The tables and figures on this web have appeared in the various publications mentioned above, and are updated to provide the most current information online. The two most important recent working papers dealing with nuclear data are: US-USSR/Russian Strategic Offensive Nuclear Forces 1945-1996 (January 1997) and U.S. Inventories of Nuclear Weapons and Weapon-Usable Fissile Material (revised 26 September 1995).
