The Department of Energy and Los Alamos National Laboratory have released the LANL congressional budget request for the upcoming fiscal year, 2026, which begins on October 1, 2025. The request shows a continued major increase and expansion of the plutonium pit production program (plutonium pits are the triggers of nuclear weapons). LANL is frantically trying to increase its capabilities to begin making 30 pits per year by 2028.
NukeWatch created the attached chart to give a visual of how taxpayer dollars are annually spent at the Lab. LANL’s FY 2026 total budget request is $6 billion, which is a 17% increase over the FY 2025 $5.2 billion total budget. This includes a 24% increase in the nuclear weapons budget over FY 2025.
Nuclear Weapons Activities represent 84% of LANL’s total budget.
Under the headline of “Unleashing a Golden Era of Energy Dominance and Energy Innovation and Protecting the Nation,” the nuclear weapons budget is increasing dramatically. As a baseline, 65% of the Department’s proposed $46 billion budget is earmarked for its semi-autonomous nuclear weapons agency, the National Nuclear Security Administration (NNSA). In turn, more than 80% of NNSA’s proposed FY 2026 funding is for its nuclear weapons research and production programs, with a 25% funding increase over FY 2025.
Due to so-called “reconciliation” funding, “Total Weapons Activities” increase to just under $30 billion. This adds up to a 53% increase above FY 2025 for the nuclear weapons research and production programs across the country. To help pay for this, national nonproliferation and cleanup programs are being cut by 5%, science by 14%, cybersecurity and emergency response by 25%, and energy efficiency and renewable energy programs by 74%.
