SBIR 25.4 Release 12

Submissions Open 24 September 2025

ANNOUNCEMENT: Congressional authorization of the SBIR and STTR programs is set to expire on September 30, 2025. Due to the absence of the congressional reauthorization of the programs as of September 23, 2025, the pre-release period for SBIR BAA 25.4 Release 12 & STTR BAA 25.D Release 12 will be extended and topics will not open on September 24, 2025, as originally scheduled.

The Department anticipates the 25.4 and 25.D Release 12 topics will open on the first Wednesday following program reauthorization, with the closing dates extended accordingly to maintain a four-week open period for proposal submissions.

Overview
The purpose of the Small Business Innovation Research (SBIR) program is to strengthen the role of innovative Small Business Concerns (SBCs) in federally-funded research or research and development (R/R&D). The Small Business Technology Transfer (STTR) program stimulates a partnership of ideas and technologies between innovative SBCs and non-profit Research Institutions. By providing awards to SBCs for cooperative R/R&D efforts with Research Institutions, the SBIR and STTR programs assist the U.S. small business and research communities by supporting the commercialization of innovative technologies. The SBIR/STTR programs employ a phased process:

Phase I: Phase I involves a solicitation of contract proposals or grant applications to conduct feasibility-related experimental or theoretical R/R&D related to described agency requirements. These requirements, as defined by agency topics contained in a solicitation, may be general or narrow in scope, depending on the needs of the agency. The object of this phase is to determine the scientific and technical merit and feasibility of the proposed effort and the quality of performance of the SBC with a relatively small agency investment before consideration of further Federal support in Phase II.

Phase II: The object of Phase II is to continue the R/R&D effort from the completed Phase I.

Direct to Phase II: Department of War may issue a Phase II SBIR award to an SBC that did not receive a Phase I SBIR or STTR award for that R/R&D. Direct to Phase II involves a solicitation of contract proposals and the SBC’s proposal must demonstrate the scientific and technical merit and feasibility of the ideas that appear to have commercial potential.

Phase III: The objective of Phase III, where appropriate, is for the small business to pursue commercialization objectives resulting from the Phase I/II R/R&D activities. The SBIR/STTR programs do not fund Phase III.
