ICBM Modernization: Approaches to Basing Options and Interoperable Warhead Designs Need Better Planning and Synchronization.

摘要

U.S. nuclear weapons--both the bombs and warheads and their delivery systems --are aging beyond their intended service lives. The 2010 Nuclear Posture Review recommended that the Nuclear Weapons Council study options for extending the life of ICBM warheads, including the potential for developing a warhead that is interoperable on both Air Force and Navy missiles. In 2013 DoD will initiate a study to identify a replacement for the Minuteman III missile. This report addresses the extent to which DoD has assessed the capability requirements, potential basing options, and costs for the follow-on to the Minuteman III ICBM; and DoD and DOE have explored the feasibility of incorporating an interoperable warhead concept into the long-term nuclear weapons stockpile plan. GAO analyzed DoD and National Nuclear Security Administration (NNSA) policies, plans, guidance, and other documents; and interviewed officials responsible for planning the Minuteman III follow-on and the warhead life-extension program. GAO is making seven recommendations to provide complete cost estimates to the Nuclear Weapons Council and improve synchronization between DoD and DOE; to identify long-term Navy funding to support the interoperable warhead life-extension program; and to issue or revise existing DoD and Nuclear Weapons Council guidance. In written comments on a draft of this report, DoD concurred with all of GAO's recommendations, and DOE concurred with the three recommendations requiring joint action between the two departments.
