For the first time in two decades, the Bush administration recently selected the prototype design of a new U.S. nuclear warhead. Managers of the U.S. nuclear complex say the program, the Reliable Replacement Warhead (RRW), will lead to safer warheads that are more reliable and easier to maintain than existing warheads. Yet, U.S. officials affirm that the current U.S. stockpile is safe and reliable. Critics of RRW assert the program is unnecessary and could lead to a resumption of nuclear testing, which the United States halted in 1992. They also contend that if the United States renewed nuclear testing or developed warheads designed for new military missions, other countries might follow suit. The panelists discussed ongoing efforts to maintain the existing stockpile and the potential pitfalls of pursuing new warheads, including the adverse impacts on global nonproliferation efforts.
