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. 

Recent (FY23-25) authorized funding amounts for Space Force’s combined RDT&E and O&M within the National Defense Authorization Acts:
Fiscal Year Category Amount Requested ($000’s) Amount Authorized ($000’s)
FY2023 RDT&E (“TOTAL RDT&E, SPACE FORCE”) $15,819,372 $16,589,070
O&M (“TOTAL OPERATION & MAINTENANCE, SPACE FORCE”) $4,034,658 $4,184,378
Total $20,773,448
FY2024 RDT&E (“TOTAL RESEARCH, DEVELOPMENT, TEST & EVAL, SF”) $19,199,340 $19,701,916
O&M (“OPERATION AND MAINTENANCE, SPACE FORCE”) $5,017,468 $4,963,441
Total $24,665,357
FY2025 RDT&E (“TOTAL RESEARCH, DEVELOPMENT, TEST & EVAL, SF”) $18,700,153 $18,371,754
O&M (“TOTAL OPERATION AND MAINTENANCE, SPACE FORCE”) $5,292,272 $5,217,272
