Defense SBIR/STTR Funding Opportunities

Defense SBIR/STTR Funding Opportunities is sponsored by Department of Defense (DoD). The DoD SBIR/STTR programs use Broad Agency Announcements (BAAs) and Commercial Solutions Openings (CSOs) to procure basic and applied research for scientific study and experimentation.

These programs support small businesses conducting innovative R&D to advance the state-of-the-art and increase knowledge, with a focus on defense-related technologies, including AI.

Topics and solicitations are known by many names including Request for Proposals (RFP), Funding Opportunity Announcement (FOA), Broad Agency Announcement (BAA), or simply Topic/Solicitation. No matter what it's called, they outline specific rules and guidance on how to prepare a response, also called an application or a proposal. Participating Agencies post SBIR/STTR funding opportunities on a regular periodic basis throughout the year.

Some agencies have multiple solicitations throughout the year, while others may only have one solicitation release each year. Once you identify a relevant agency to target, learn more about that specific Funding planner with estimated dates. All agencies have a 45 day lead in period.
