Nuclear Weapons Instructional Museum

DNWS manages and operates the only classified Nuclear Weapons Instructional Museum (NWIM) in the DoD.  A member of the American Alliance of Museums, the NWIM is an irreplaceable repository that traces the history and development of the U.S. nuclear weapons stockpile from its inception to the present. The NWIM contains displays of all stockpiled U.S. nuclear weapons and their associated components and delivery systems, as well as related training aids.  Touring the NWIM display affords students and visitors a rare opportunity to view exhibits and discuss stockpile issues with experienced instructors.
