The Department of Defense (DoD) Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs are Congressionally authorized small business set-asides established to support scientific excellence and technological innovation through investment of Federal research funds in critical American priorities to build a strong national economy.

SBIR is a competitive three-phased process to solicit proposals for Research/Research and Development (R/R&D), production, services, or any combination to meet stated agency needs or missions; and to award funding agreements to qualifying Small Business Concerns (SBCs).

STTR is a parallel program to SBIR with the added requirement that SBCs partner with colleges/universities, Federally Funded Research and Development Centers (FFRDCs) or qualified non-profit research institutions on cooperative R/R&D.

The goal of these programs is to stimulate technological innovation for the DoD to maintain technological superiority and military readiness to deter military operations from U.S adversaries by:
  • Increasing private sector commercialization of Federal R&D to increase competition, productivity, and economic growth.
  • Stimulating a partnership of ideas and technologies between innovative small businesses and research institutions (STTR).
  • A competitive awards-based program, SBIR/STTR enables small businesses to explore their technological potential and provides the incentive to profit from its commercialization.
  • Including qualified small businesses in the nation’s R&D arena, high-tech innovation is stimulated and the United States gains entrepreneurial spirit as it meets its specific R&D needs.
Oversight of the DoD SBIR and STTR programs falls under the Office of the Under Secretary of Defense Research and Engineering (OUSD(R&E)). The DoD program encompasses participation from 14 DoD Services and Components, with a combined annual budget of nearly $2 billion.

Throughout the year, the DoD issues a series of Broad Agency Announcements (BAAs) and Commercial Solutions Openings (CSOs), through which the DoD Components release SBIR and STTR topics based on the Research/Research & Development (R/R&D) needs of the Component. Eligible small business with the capability to conduct R/R&D in the published topic areas are encouraged to submit proposals. Guidance on how to participate and what to expect during each step of the process can be found below.


Broad Agency Announcements (BAAs) and Commercial Solution Openings (CSOs) are the primary mechanisms utilized by the DoD for advertising SBIR/STTR topics. Eligible small businesses are encouraged to review active and upcoming BAAs/CSOs, topics, and full submission instructions on the Funding Opportunities page.
