The National Academy of Sciences was established in 1863 by an Act of Congress, signed by President Lincoln, as a private, nongovernmental institution to advise the nation on issues related to science and technology. Members are elected by their peers for outstanding contributions to research. Dr. Marcia McNutt is president.

The National Academy of Engineering was established in 1964 under the charter of the National Academy of Sciences to bring the practices of engineering to advising the nation. Members are elected by their peers for extraordinary contributions to engineering. Dr. Tsu-Jae Liu is president.

The National Academy of Medicine (formerly the Institute of Medicine) was established in 1970 under the charter of the National Academy of Sciences to advise the nation on medical and health issues. Members are elected by their peers for distinguished contributions to medicine and health. Dr. Victor J. Dzau is president.

The three Academies work together as the National Academies of Sciences, Engineering, and Medicine to provide independent, objective analysis and advice to the nation and conduct other activities to solve complex problems and inform public policy decisions. The National Academies also encourage education and research, recognize outstanding contributions to knowledge, and increase public understanding in matters of science, engineering, and medicine.

Preface

This report is the result of a request by Congress for an assessment of the Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs at each of the principal agencies that conduct or fund research and development (R&D) activities across the federal government. The SBIR program has become the largest and most comprehensive public R&D funding program for small business research in the United States, and indeed has been emulated by other countries. An underlying tenet of the SBIR program, and the related STTR program, is that small and young firms are an important source of new ideas that provide the basis for technological innovation, productivity increases, and subsequent economic growth. Predicated on the observation that it is difficult for small and young firms to find financial support for their ideas, the SBIR/STTR programs have become known as America’s Seed Fund.

Yet this characterization captures only one dimension of the legislative objectives and operation of the programs. By involving qualified small businesses in the nation’s R&D efforts, SBIR/STTR awards stimulate the development of innovative technologies, help move research closer to the market, and address the needs of citizens underserved because of limited market incentives. Equally important, and particularly relevant for the current report, the SBIR/STTR programs aim to help federal agencies fulfill their missions and objectives by stimulating technological innovation that meets agency needs—first by funding early-stage R&D, and ultimately by integrating successful technologies into use through procurement and other means.

Specifically, this report focuses on the operation and performance of the SBIR/STTR programs at the Department of Defense (DOD). As the largest and most complex of the federal SBIR/STTR programs, encompassing more than a dozen distinct service and agency components, the DOD SBIR/STTR enterprise reflects the scale and diversity of the Department’s mission—from fundamental science to applied technology and procurement. The committee convened by the National Academies of Sciences, Engineering, and Medicine to carry out this study undertook a detailed assessment of the process by which SBIR and STTR awards are made at DOD; a survey of the landscape of awards that have been granted; and a detailed quantitative analysis examining the innovation, commercialization, and follow-on funding outcomes of firms participating in the programs. Collectively, these analyses, documented in this report, are intended to

Suggested Citation: "Front Matter." National Academies of Sciences, Engineering, and Medicine. 2026. Review of the SBIR and STTR Programs at the Department of Defense. Washington, DC: The National Academies Press. doi: 10.17226/29329.

offer a more comprehensive and precise assessment of the SBIR and STTR programs than has been provided in previous studies of this agency carried out by the National Academies. Here we highlight three broad themes from the report and make one plea for a more systematic data infrastructure to help understand and quantify outcomes stemming from the programs.

First, the DOD SBIR and STTR programs play a central role in advancing DOD’s mission by connecting the nation’s small business innovators directly to defense research, development, and operational needs. These programs strengthen the Department’s ability to identify, fund, and integrate innovative technologies that support national defense—first through early-stage R&D and, ultimately, through procurement and fielding of new capabilities. While the evidence for large procurement contracts is more difficult to ascertain (both because of data issues related to subcontracting and also because these technologies are typically part of larger systems whose primary contractors are much larger firms), the overall tenor of the evidence in the report supports the idea that the DOD SBIR/STTR program has been successful in its goals of supporting the mission of DOD itself. Moreover, the cumulative effect of the program is to serve as a vital bridge between the small business and startup innovation ecosystem and the Department’s mission-oriented R&D enterprise.

Second, firms require substantial experience engaging with DOD before their innovations are effectively incorporated into the defense R&D and acquisition system. Firms that have received multiple SBIR/STTR awards—particularly those with at least five Phase I projects—are substantially more likely to generate inventions, secure follow-on DOD or private funding, and contribute meaningfully to defense capabilities. These findings highlight that learning to navigate DOD’s complex contracting and technical environment is itself an important part of the innovation process. Recent legislative provisions that restrict the participation of “experienced” firms in the SBIR/STTR programs are therefore not supported by the data and risk constraining the pool of high-performing small businesses that the Department depends upon. Moreover, these requirements impose additional administrative burdens on DOD program managers and reduce flexibility to fund the most meritorious projects. The evidence suggests that experience in the DOD context should be viewed as an asset (or at least a neutral rather than negative attribute) in leveraging small business innovation to meet defense needs.

Third, the emergence of open topic SBIR programs—first pioneered by the Air Force under AFWERX and subsequently adopted by other DOD components—represents an important experiment in widening access to the defense innovation system. The evidence suggests that these open approaches can be valuable for identifying nontraditional suppliers and attracting new entrants, particularly in large and technologically diverse organizations. However, the report also finds that a single, uniform approach is unlikely to serve the entire Department effectively. Smaller or more specialized agencies often face significant administrative burdens in processing open topic proposals and may

find traditional, solicitation-driven approaches better aligned with their specific mission needs.

Finally, with the ongoing evaluations of the DOD SBIR/STTR programs, there remains a critical need for a coherent framework and system that track these investments and communicate their outcomes effectively across the Department. The committee’s work demonstrates that a more integrated data infrastructure (linking awards across phases and components and making those linkages visible through a more visible and accessible portal) would provide the foundation for assessing progress and informing both leadership and the broader innovation community. Further, research and innovation are driven by individuals (scientists, engineers, and entrepreneurs whose careers intersect repeatedly with the defense innovation system). Enhancing the capacity to track the role of individual researchers would yield a deeper understanding of knowledge flows, supply chain linkages, and the cumulative contribution of SBIR/STTR to DOD’s mission. Greater transparency and accessibility of data would not only strengthen program management but also reinforce public confidence in the value and stewardship of these vital national investments.
