Defense SBIR/STTR Broad Agency Announcement (BAA) is sponsored by Defense Advanced Research Projects Agency (DARPA). DARPA publishes multiple SBIR/STTR topic opportunities under the Department of Defense (DoD) Broad Agency Announcement (BAA). These topics seek innovative solutions from small businesses in response to national security challenges.
Some open topics, such as "Art of Novel Signals: Predicting and Forecasting with High Confidence" and "Fusion of Abstract Learning and Context-Optimized Neural-methods (FALCON)" directly relate to machine learning, AI, and large-scale data analysis, which could have applications in biomedical data science, particularly in areas like disease surveillance or computational biology for defense health.

DPA26BZ06-DV023 is a Direct-to-Phase-II SBIR paying $700,000 over 18 months plus a $500,000 option. The physics demands 256x more transmit power than the systems that qualify you to compete, and DARPA will not accept modeling alone as proof. Here is the eligibility wall, the five engineering problems, and who can realistically win it before the October 21 close.
Read articleRelease 6's SBIR topics got the attention. Its three STTR topics — SHIELDER, fuel-flexible electric propulsion, and hypersonic wind tunnel noise diagnostics — are all Direct-to-Phase-II, all require a research institution to perform at least 30 percent of the work, and all close October 21, 2026. The feasibility gates are the real filter.
Read articleDPA26BZ06-DV026 offers $300,000 at Phase I or $1,800,000 as a single Direct-to-Phase-II tranche with no options. The deliverable is a simulated auction market that measures whether AI agents deceive, collude, or manipulate the humans they serve — measured entirely from the outside. Here is the 90% efficiency gate, the team composition most bidders will get wrong, and why this topic sits in DARPA's biology office.
