NNSA's Reliable Replacement Warhead (RRW) Program: Modernizing the Nuclear Weapons Complex Today To Make It More Responsive to the Challenges of Tomorrow [Fact Sheet] [open pdf - 168KB]
"In order to achieve President Bush's vision of the smallest nuclear weapons stockpile needed for our national security, the National Nuclear Security Administration (NNSA) has outlined a strategy that will not only reduce the number of weapons, but lead to a safer and more secure stockpile, with weapons that are more easily manufactured and maintained, backed up by a more responsive nuclear weapons infrastructure. The vehicle for this transformation is NNSA's concept for the Reliable Replacement Warhead (RRW). RRW is not a new weapon providing new or different military capabilities and/or missions. It will meet the same military requirements as current legacy warheads by utilizing replacement components. It will be able to ensure greater long-term confidence in safety and reliability while decreasing the likelihood that underground nuclear testing would ever be needed to ensure that confidence. Through innovative and enhanced safety and surety features, RRW will also have the capability to prevent unauthorized use."
