The Senate Appropriations Committee wants to order the Energy Department to launch an investigation into technical problems that have recently plagued U.S. nuclear weapons programs.
The committee’s mandate is buried deep inside the report accompanying the $48.9 billion Energy-Water spending bill that the committee approved on Sept. 12.
The panel is concerned that recent glitches in atomic weapons may have broader implications, and senators want to get to the bottom of the issue. Separately, a congressional aide familiar with the issue said the problems will add hundreds of millions of dollars to the atomic weapons budget.
“The Committee is concerned that a recent technical challenge demonstrates a lack of systems engineering and highlights a lack of coordination and leadership focus, which in turn jeopardizes successful program execution,” the report says.
The document does not mention any particular programs or provide details on the nature of the technical challenges. But experts on nuclear weapons said the panel is almost certainly referring to problems with two new weapons: a bomb called the B61-12 and a modified submarine-launched warhead called the W-88.
In both those programs, problems with commercially manufactured electrical components have caused months of delays, U.S. government officials have publicly acknowledged.
In another sign of intensifying congressional concern over the programs, the House Armed Services Subcommittee on Strategic Forces plans to hold a hearing Sept. 25 on those two programs.
Senate appropriators suggested in their report that they are worried the delays in these programs may reflect fundamental oversight shortcomings and could cause ripple effects in other nuclear initiatives, such as keeping nuclear weapons out of terrorists’ hands, updating warship reactors and modernizing facilities.
The investigation must find causes and solutions, the panel said, and it must “ensure the extent of condition is not more widespread than currently reported.”
The Energy Department organizations responsible for nuclear arms “need to ensure any technical challenges or production issues, particularly in the electronic components, are discovered quickly and mitigated to minimize impacts” on the programs at issue and the department’s other priorities.
Experts said ballooning costs and schedule delays are an ongoing problem at the National Nuclear Security Administration, the Energy Department agency that manages atomic arms programs.
The latest glitches also show how dependent the secret weapons initiatives are on items available in the commercial marketplace.
“It is astounding that these two programs, which together were estimated to cost roughly $12 billion before this new problem was discovered, are being delayed because a commercially produced electronic component does not meet specifications,” said Stephen Young, a nuclear arms specialist with the Union of Concerned Scientists. “The good news is, because of how robust the U.S. deterrent is, this will not materially affect American security. But it is still a troubling sign for an agency that has so much work on its plate.”
The B61 is the oldest nuclear weapon in the U.S. arsenal. It was first fielded in 1968. Its current four configurations would be replaced by the new B61-12.
The first production version of the B61-12 was supposed to be ready as early as this month, Energy Department officials said in 2018.
But this past May, officials disclosed in congressional testimony and interviews that both the B61-12 and the W-88 modification would be delayed.
At a Senate Armed Services Subcommittee on Strategic Forces hearing in May, South Dakota Republican Mike Rounds asked Lisa Gordon-Hagerty, the head of the National Nuclear Security Administration, whether the B61-12 would be ready in 2023 as planned.
“That should be beyond 2025,” Gordon-Hagerty said, noting that “an issue” had arisen, without elaborating.
Energy officials subsequently confirmed a few details about the problems, including that they involved electrical components. They said the delay to the B61-12 program could be a year to 18 months.
Gordon-Hagerty is one of five finalists to replace John Bolton as national security adviser, President Donald Trump said Tuesday.
