What will the U.S. Space Force budget be in the FY2026 National Defense Authorization Act?
Congressional appropriations for the U.S. Space Force’s Operations and Maintenance (O&M) and Research, Development, Testing, and Evaluation (RDT&E) accounts have fluctuated in recent years. The National Defense Authorization Act (NDAA) for FY2023 authorized a combined total of $20.8 billion for these accounts, which increased to $24.7 billion in FY2024, before decreasing to $23.6 billion in FY2025. (NOTE: All amounts in the linked NDAAs are listed in thousands of dollars.)
The final FY2026 NDAA, likely to be passed in December 2025, will determine whether this trend of year-to-year changes continues for Space Force O&M and RDT&E funding.
Resolution Criteria: The final calculation for the U.S. Space Force budget will be taken from the FY2026 National Defense Authorization Act, as published by the U.S. Congress. Specifically, the budget number will be the combined amount from the U.S. Space Force Operations and Maintenance (O&M) and Research, Development, Testing, and Evaluation (RDT&E) appropriations. This question will resolve according to the appropriated amount in the FY2026 NDAA or according to the appropriated amount in a potential FY26 Continuing Resolution (CR) and will remain open until the NDAA or CR is passed.
