President’s Fiscal Year 2025 budget for NNSA advances ongoing modernization, strengthens response to deteriorating global environment

WASHINGTON – The Department of Energy’s National Nuclear Security Administration (DOE/NNSA) released its portion of President Biden’s Fiscal Year 2025 Budget. The proposal reflects a demanding, expanded mission. Across all its portfolios, NNSA is delivering in this geopolitically complicated moment.

With this Budget, NNSA will deliver a safe, secure, reliable, and modernized nuclear stockpile to enable an effective deterrent, and to support NNSA’s recapitalization of key production capabilities. It will advance nonproliferation and nuclear security efforts in response to deteriorating strategic stability conditions, while enabling the naval nuclear reactor mission. In light of emerging and disruptive technologies, such as artificial intelligence, the Budget also supports strong investments in science, technology, and engineering across the enterprise.

The FY 2025 Budget of $25 billion is an increase of $865 million, or 3.6%, over the FY 2024 enacted level. It builds on years-long bipartisan efforts to modernize and invest in capabilities that underpin U.S. strategic deterrence.

“President Biden’s FY 2025 Budget reflects today’s real-world conditions and our need to deliver while transforming the Nuclear Security Enterprise,” said Under Secretary of Energy for Nuclear Security and NNSA Administrator Jill Hruby. “We appreciate the long-standing bipartisan and bicameral support from Congress that allows us to design and deliver a modernized stockpile, forge solutions with allies and partners that enable global security and stability, power a global naval fleet, and leverage transformative technologies to stay ahead of emerging challenges.”

The request is fully informed by and supports the President’s Nuclear Posture Review and National Security Strategy, is aligned with Department of Defense requirements to ensure an effective U.S. nuclear deterrent, and accounts for the findings of the bipartisan Strategic Posture Commission Report.

• The $19.8 billion request for Weapons Activities supports ongoing weapon modernization programs and an expanded program of record. The Weapons Activities budget also invests in infrastructure revitalization and modernization, with the goals of increasing our flexibility and resilience, introducing modern and efficient technologies to improve safety and schedule, and exercising fiscal responsibility.
• The $2.5 billion request for Defense Nuclear Nonproliferation continues critical investment in our nonproliferation, emergency response, and counterterrorism programs. It helps prepare for potential nuclear arms control arrangements and advances U.S. national technical capabilities. It also recognizes that the growing global role of nuclear energy may challenge existing nuclear nonproliferation and security norms and capacities. NNSA stands ready to contribute to new and flexible solutions.
• The $2.1 billion request for Naval Reactors supports progressing modernization of Naval Reactors infrastructure in Idaho and investments to develop, refine, and deliver new technologies to the U.S. Navy and maintain America’s advantage over its adversaries.
• The $564.5 million request for Federal Salaries and Expenses supports the Federal staff required to provide appropriate guidance and oversight to allow NNSA to meet growing mission requirements. NNSA aims to recruit and retain a highly skilled workforce to staff the Nuclear Security Enterprise, and to develop the next generation of nuclear security leaders.
