The U.S. Government Accountability Office says the National Nuclear Security Administration (NNSA) identified and prioritised a slate of science, technology and engineering (ST&E) facility investments for the next two decades, but stopped short of analysing the workforce and broader programmatic funding those facilities will require.
Key findings from the GAO review
In July 2024, the NNSA released an internal Integrated Science, Technology, and Engineering Plan that lays out investments it considers necessary over the next 20 years to support stewardship of the U.S. nuclear weapons stockpile and related missions. The plan prioritised 46 ST&E facility investments, including sustainment and enhancement of existing capabilities and construction of new facilities.
- The plan prioritised investments by mission importance and by mission-need timeframe.
- NNSA collected initial estimates of related workforce and programmatic needs from enterprise sites but did not complete a full assessment of those needs.
- NNSA officials said the plan emphasised facilities to meet a deadline for the agency’s Enterprise Blueprint and the agency has no plans to finish the comprehensive workforce and funding analysis.
The GAO report warns that without a completed analysis of workforce and programmatic investment needs — such as equipment and materials over the same 20-year horizon — the agency cannot fully understand the total funding required to carry out stockpile stewardship activities or proactively plan for them.
Operational context and examples
The review references work performed at major laboratories and facilities that support NNSA missions, including the National Ignition Facility and the Annular Core Research Reactor. These facilities rely on specialised personnel and sustained programme funding to deliver capabilities the NNSA says are essential to maintaining a safe and effective nuclear stockpile.

Implications and recommended actions
The GAO made recommendations aimed at strengthening NNSA’s ability to sustain the stockpile amid shifting priorities and technological change. Completing a comprehensive analysis of ST&E workforce and programme funding needs would allow the agency to estimate total costs more accurately and to anticipate recruitment, training and procurement demands that accompany major facility investments.
According to the audit, NNSA has not committed to finishing that analysis. That gap leaves potential risks: projects could face shortfalls in trained personnel or in equipment and materials budgets, and decision-makers may lack the consolidated data needed to weigh trade-offs across competing investments.
The GAO’s findings underscore the interplay between physical infrastructure and human capital in sustaining specialised national-security missions. For policymakers and planners, the audit highlights that facility modernisation is only one element of capability maintenance; workforce planning and programmatic funding are equally necessary to realise intended outcomes.
As the NNSA moves forward with its Enterprise Blueprint, the choices it makes about when and how to assess workforce and programmatic requirements will influence not only cost estimates but also the agency’s ability to execute long-term stewardship responsibilities.
