The Reliable Replacement Warhead Program: Background and Current Developments

Abstract

Most current U.S. nuclear warheads were built in the 1970s and 1980s and are being retained longer than was planned. Yet they deteriorate and must be maintained. To correct problems, a Life Extension Program (LEP), part of a larger Stockpile Stewardship Program (SSP), replaces components. Modifying some components would require a nuclear test, but the United States has observed a test moratorium since 1992, because Congress and the Administration prefer to avoid a return to testing, so LEP rebuilds these components as closely as possible to original specifications. With this approach, the Secretaries of Defense and Energy have certified stockpile safety and reliability for the past 11 years without nuclear testing. The National Nuclear Security Administration (NNSA) operates the nuclear weapons program; it sees RRW as part of a plan that would also modernize the nuclear weapons complex, avoid nuclear testing, and reduce non-deployed weapons. For FY2005, Congress provided $9.0 million, which was not requested, to start the Reliable Replacement Warhead (RRW) program. Issues facing the 110th Congress include how best to maintain the nuclear stockpile, whether to continue RRW or cancel it in favor of LEP, and how RRW might link to the Comprehensive Test Ban Treaty and nuclear nonproliferation. This report provides background and tracks legislation. It will be updated often. CRS Report RL33748, Nuclear Warheads: The Reliable Replacement Warhead Program and the Life Extension Program, compares these two programs in detail.
