Background[ edit ] During the Cold Warthe United States, in an effort to achieve and Confidence cement an advantage in the nuclear arms race with the Soviet Unioninvested large amounts of money and technical resources into Confidence cement weapons design, testing, and maintenance.
Many of the weapons designed required high upkeep costs, justified primarily by their Cold War context and the specific and technically sophisticated applications they were created for.
With the end of the Cold War, however, nuclear testing has ceased in the United States, and new warhead development has been significantly reduced. As a result, the need for high technical performance of warheads has decreased considerably, and the need for a longer-lasting and reliable stockpile has taken a high priority.
Prior nuclear weapons produced by the U. A number of older US designs used high explosive types which degraded over time, some of which became dangerously unstable in short lifetimes PBX and LX The long term stability of plutonium metal, which may lose strength, crack, or otherwise degrade over time is also a concern.
See Nuclear weapons design and Teller-Ulam design for technical context. The question of whether the plutonium-gallium alloy used in the cores of the weapons suffered from aging has been a major topic of research at the weapons laboratories in recent decades.
Though many at the labs still insist on scientific uncertainty on the question, a study commissioned by the National Nuclear Security Administration to the independent JASON group concluded in November that "most plutonium pits have a credible lifetime of at least years".
Concept[ edit ] The concept underlying the RRW program is that the US weapons laboratories can design new nuclear weapons that are highly reliable and easy and safe to manufacture, monitor, and test.
If that proves to be possible, designers could adapt a common set of core design components to various use requirements, such as different sized missile warheads, different nuclear bomb types, etc.
NNSA officials believe the program is needed to maintain nuclear weapons expertise in order to rapidly adapt, repair, or modify existing weapons or develop new weapons as requirements evolve.
They see the ability to adapt to changing military needs rather than maintain additional forces for unexpected contingencies as a key program driver. In providing funds forthe Appropriations Committee specified, "any weapons design under the RRW program must stay within the military requirements of the existing deployed stockpile and any new weapon design must stay within the design parameters validated by past nuclear tests".
Support an adaptable 1, weapon sustained force level 3. The RRW program has not to date publicly announced that it has developed any new nuclear weapon designs which are intended to be placed into production.
Presumably, once that occurs, the weapons will receive numbers in the US warhead designation sequence, which currently runs from the Mark 1 nuclear bomb aka Little Boy to the W91 nuclear warhead, which was cancelled in the s. RRW designs would presumably receive designations after that number, though new RNEP nuclear bunker buster weapons could conceivably be type-standardized and numbered prior to any RRW reaching that point, if the RNEP program does proceed.
It was described by Thomas P. D'Agostino, acting head of the National Nuclear Security Administrationas having been based on a design which was test fired in the s, but never entered service.
The W89 was also reportedly designed using recycled pits from the earlier W68 nuclear weapon program, recoated in vanadium to provide the temperature resistance.
