Federal Facility Expenditures for R&D Performance

The federal government sector’s performance of R&D is highly concentrated among a handful of departments and agencies. DOD alone accounted for 77% of all federal R&D performance in FY 2025 (figure 1).^{​Although year-to-year trend data are presented in this report to the tenth place, data presented as a percentage share are rounded to whole-percents.} Within DOD, the Air Force accounted for 45% of all federal R&D performance, and Army and Navy contributed 10% and 14%, respectively, all of which are larger shares of federal R&D performance than any single civilian department. HHS and NASA, the leading civilian agencies with federal facility R&D performance, accounted for 7% and 5%, respectively, of the federal total.

Since DOD expenditures for R&D performance are a substantial component of the federal portfolio, its increase of 16% has a significant effect on total federal R&D expenditures from FY 2024 to FY 2025. DOD’s increase is consistent with changes in DOD’s budget authority for research, development, test, and evaluation (RDT&E) programs from FY 2022 to FY 2023, which can take 1 to 3 years, or more, to make it from appropriation to expenditure.^{​Budget authority is the primary source of legal authorization to enter into obligations that will result in future outlays. Outlays, also referred to as expenditures, are disbursement of cash, checks, and electronic transfers to execute previous obligations.} Although R&D is a subset of DOD’s total RDT&E funding, there are similarities in the trends between the budget authority for RDT&E and expenditures for R&D. For example, DOD’s budget authority for RDT&E funding increased 18% from FY 2022 to FY 2023.^{​For more data on DOD RDT&E budget authority, see Federal R&D Funding, by Budget Function: Fiscal Years 2022–24: table 6.} DOD also had a 17% increase in RDT&E expenditures from $73.4 billion in FY 2024 to $85.9 billion in FY 2025.^{​For more data on DOD RDT&E expenditures, see the full set of data tables: table 2.} The Congressional Budget Office (CBO) has also noted the purposes of the increases in DOD’s RDT&E account are to shift funding toward weapons systems for more conventional warfare.^{​Congressional Budget Office. 2023. Long-Term Implications of the 2024 Future Years Defense Program, p. 19. Available at https://www.cbo.gov/system/files/2023-10/59511-FYDP.pdf.}

Type of R&D

Across all federal facilities, most of the expenditures for R&D performed within the facilities was for experimental development (74%, or $39.2 billion) (figure 2).^{​See the Technical Notes to the FY 2025 data tables for the definitions of basic research, applied research, and experimental development that were provided to survey respondents.,​For more details on federal R&D performance by type of R&D, see the full set of data tables: table 8.} Another 16% ($8.6 billion) was categorized as applied research, and nearly 10% ($5.1 billion) was for basic research.

This distribution of type of R&D activities varies considerably by agency. Just as DOD accounts for a large portion of the federal total for R&D performance, in FY 2025 DOD accounted for 94% ($36.8 billion of $39.2 billion) of all experimental development.^{​For more details on federal R&D performance by type of R&D, see the full set of data tables: table 8.} The majority of the remaining civilian agencies reported most of their expenditures as applied research. Only two agencies reported basic research as their largest category: the Department of Homeland Security (74%, or $7.6 million of their $10.3 million total) and the Smithsonian with 100% of its $169 million as basic research.

Fields of R&D

The R&D performed within federal facilities spans all of the major fields of R&D. In FY 2025, engineering alone accounted for nearly 52% ($27.3 billion) of all federal R&D performance (table 2).^{​Engineering encompasses a wide array of work in subfields such as aerospace, biomedical, chemical, civil, environmental, electrical, computer, industrial, systems, mechanical, materials, and geological engineering.} Biological, biomedical, and health sciences accounted for 13% ($6.9 billion). Within DOD facilities, most of the R&D was for engineering (63%, or $25.6 billion), and all other fields, meaning not classified in one of the listed fields, accounted for 26%, or $10.7 billion. Within civilian agency facilities, biological, biomedical, and health sciences R&D accounted for the largest share at 49% or $6.0 billion. Engineering was the second largest field of R&D performed by civilian agency facilities, accounting for 14% or $1.7 billion of their total R&D expenditures.

FY 2025 R&D Personnel

A total of 166,539 personnel were reported or estimated as working on R&D within federal facilities in FY 2025, a decline of 10% from the 184,899 personnel reported or estimated in FY 2024 (figure 3). Of the 166,539 R&D personnel in FY 2025, 71% or 119,034 were federal employees or military personnel.

When total R&D personnel headcounts of federal employees are converted to full-time equivalents (FTEs), the total FTE of federal employees and military personnel working on R&D was 100,358 in FY 2025.^{​For more details on federal R&D personnel by full-time equivalents, see the full set of data tables: table 13 and table 15.} DOD still leads all federal R&D facility FTEs, accounting for 55% of the federal FTE total (figure 4). NASA is the second leading agency, accounting for 16%. HHS and the Department of Agriculture accounted for 9% and 7%, respectively, of total R&D facility FTEs in FY 2025.

Data Sources, Limitations, and Availability

Detailed tables showing these data by reporting facility are available at https://ncses.nsf.gov/surveys/federal-facilities-research-development/2025.

The survey was conducted from January 2026 through April 2026 as a census of the population of federally owned and operated facilities in the United States that performed R&D in FY 2025. The overall response rate was 96%. Imputation was performed to account for nonresponding facilities. The survey collected information on R&D expenditures by type of cost, type of R&D, source of funding, and field, as well as information on counts of R&D personnel.

A facility is defined as a unit within the agency that is responsible for performing R&D, generally with its own distinct budget and leadership. Because each agency has a different organizational structure, this unit of measurement may be a division, branch, center, laboratory, or other entity and may span multiple locations. Because of this, the total number of reporting units for the FY 2025 Federal Facilities Survey is 289, which represents the 443 research-performing federal facilities.

The fiscal year referred to throughout this report is the federal fiscal year (1 October 2024 to 30 September 2025). Data tables and detailed technical information are available at the FY 2025 Federal Facilities Survey page. For more information, please contact NCSES.
