Dr. Andrew Weston-Dawkes
Director
Office of Classification
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 the end of Fiscal Year 2015.

As you know, the Departments of Energy and Defense have previously 
declassified such information for each fiscal year through FY 2014.  
We are now requesting that similar information be disclosed for the 
fiscal year that has just concluded.

The reasons for the proposed declassification are the same as the 
reasons for the Department's previous declassification of stockpile 
information:  Nuclear transparency can strengthen non-proliferation 
efforts, and can lay a foundation for future arms control efforts.

Furthermore, as a matter of principle, information should remain 
classified only when doing so serves a valid and compelling 
national security purpose.  We suggest that continued classification 
of the size of the nuclear stockpile does not meet that criterion.

We therefore request that the Department consider declassifying this 
information, as provided in 10 C.F.R. 1045.20.

Thank you for your consideration.


Steven Aftergood
