DOE Inspector General report on the B61-12 nuclear smart bomb

The Department of Energy Inspector General has issued its audit report National Nuclear Security Administration’s Management of the B61-12 Life Extension Program. The B61-12 will literally cost twice its weight in gold. It is slated for production beginning 2020 and will blur the line between battlefield and strategic nuclear weapons by combining one strategic and three tactical variants. It will also be the world’s first “smart” nuclear bomb with a steerable tailfin kit giving it vastly improved accuracy. Nevertheless the U.S. government denies that the B61-12 will have any new military capabilities.

In its audit report, the DOE IG notes:

We believe without further improvement to its project management tools, it will be difficult for the program to proactively manage the costs, schedule, and risks of the B61-12 LEP to ensure it can deliver the First Production Unit within cost and meet its critical national security schedule.  In addition, there is uncertainty whether the original cost estimate for the B61-12 LEP contains sufficient management reserve to allow the program to respond to the numerous risks identified in the program.  Finally, not having documented assurance that unresolved significant finding investigations are a part of weapons design input significantly reduces management’s ability to ensure that redesigned nuclear weapon components have addressed prior safety and reliability concerns.

Regarding the last sentence “… reduces management’s ability to ensure that redesigned nuclear weapon components have addressed prior safety and reliability concerns”:

There was a problem with the new-design arming, firing and fuzing set for the W76-1, which is being produced now in its current Life Extension Program. It wasn’t a showstopper, but nevertheless a problem where new individual AF&F components had to be screened to determine whether their performance was affected.

The graph below from the 1993 Sandia Stockpile Life Study shows how the supermajority of nuclear weapons defects are discovered within the first few years of production. The point I’m reaching for is that as Life Extension Programs become more aggressive and more new-design components are used, design and production defects will be inevitable. It would be far better to maintain the stockpile through a conservative curatorship approach.

Circa 1995 I met with DOE Asst. Sec. for Defense Programs Victor Reis, the so-called father of the Stockpile Stewardship Program. Reis explicitly told me that the exorbitant Stockpile Stewardship Program was all about “the other side of the bathtub curve,” meaning it’s all about accelerated defects showing up at some time due to aging. Guess what? It hasn’t happened, not with ongoing surveillance and maintenance and exchange of limited life components that have been almost routine for decades. As the 1993 Sandia Stockpile Life Study concluded,

“It is clear that, although nuclear weapons ages, they do not wear out; they last as long as the nuclear weapons community (DOE and DOD) desire. In fact, we can find no example of a nuclear weapon retirement where age was ever a major factor in the retirement decision.”

Since then, the 1993 Sandia Stockpile Life Study’s conclusion has been buttressed by the JASON’s 2006 Pit Life Study and 2009 Life Extension Programs Study. In short, Life Extension Programs are not necessary for maintaining the nuclear stockpile, and may in fact undermine reliability by intentionally introducing major changes to an extensively tested stockpile. Life Extension Programs are, however, essential for creating new military capabilities for existing nuclear weapons, which is pretty clearly demonstrated by the B61-12 about to go into production, and arguably the W76-1 as well.
