                                                   Our Challenge

                   We must ensure a safe, secure, and reliable
                   nuclear deterrent for the foreseeable future.

       •    We assess increased risk in assuring long-term safety,
            security and reliability of today’s Cold War stockpile.

       •    The current nuclear weapons complex is not sufficiently
            “responsive” to fixing technical problems in the stockpile,
            or to reacting to potential adverse geopolitical change.


            Response: Explore a new approach to sustaining the
                 stockpile and supporting infrastructure.

                           The Reliable Replacement Warhead

    •       The Reliable Replacement Warhead (RRW) program is
            structured to:
             • Sustain existing military capabilities
             • Assure long-term confidence in stockpile reliability
             • Enhance stockpile safety and security
             • Use replacement components and assemblies that are
               easier to manufacture
             • Exercise critical skills
             • Help develop a responsive infrastructure
             • Enable a reduced stockpile size
             • Decrease the likelihood of underground nuclear testing


              The RRW program is structured to provide a vehicle for
                 long-term sustainability of the nuclear deterrent.

                                  RRW Decreases the Likelihood of
                                    Underground Nuclear Testing

            •   Highly optimized Cold War systems are designed close to
                performance “cliffs”
                 • Sensitive to small changes
            •   Relaxed constraints facilitate RRW design far from
                performance “cliffs”
                 • More resilient to change
            •   Confidence in predicting RRW performance without testing
                based on use of previous nuclear test data with stockpile
                stewardship tools


                         RRW is enabled by the success of the
                           Stockpile Stewardship Program.

            Increased confidence in warhead designs and demonstration of a

                                        RRW Feasibility Study
       •    Joint Navy-Air Force group overseeing an RRW design
            competition (two teams)
              • Assessing feasibility of RRW concept
              • Recommending preferred RRW design
       •    Evaluation criteria
              • Not negotiable: certain safety requirements and
                certifiable without underground nuclear testing
              • All other attributes trade-able

       •    Study to be complete November 2006
       •    Nuclear Weapons Council decides if RRW is feasible and
            recommends preferred design
             •   Congress must appropriate funds to proceed
       •    President authorizes RRW entry into the stockpile

                                                           Summary

       •    The RRW program is underway with close cooperation
            between the NNSA and DoD.
       •    NNSA has a complimentary effort to develop a strategy to
            transform to a responsive nuclear weapons complex.
       •    A successful RRW program will assure, over the long term,
            the Nation’s ability to sustain the nuclear deterrent, while
            enabling a smaller, safer, more secure, stockpile with a
            reduced likelihood that we will ever need to conduct an
            underground nuclear test.
