SBIR Phase I: Compact, High-Performance Metamaterial Acoustic Filter with Monolithic Integrated Signal Processor is sponsored by U.S. Department of Defense (Navy) / Office of Naval Research (ONR). This SBIR topic aims to develop passive acoustic metamaterials that can be integrated with existing Navy acoustic sensors for analog signal processing.
The objective is to achieve a 10X improvement in signal-to-noise ratio and a 1000X reduction in post-reception signals, thereby improving system speed and reducing sensor power consumption. While focused on undersea applications, the fundamental research could be relevant to passive acoustic drone detection.

Past winners and funding trends for this program
The Department of the Navy pre-released FY26 Release 3 SBIR/STTR on June 3, 2026 — 12 BAA topics and one Commercial Solutions Opening for Counter-Unmanned Air Systems. Topics span adaptive sensor management, anomalous behavior detection, satellite imagery optimization, real-time zero-trust data for combat systems, and gun weapon systems modernization. Technical questions cut off June 23. Proposals open June 24 and close July 22. NAVAIR and NAVSEA co-host a Counter-UAS webinar June 16. Phase I funding tops out at $315,000. The CSO open topic for AI-powered drone defense is the structural news: it's the first time NAVAIR has used a CSO vehicle to fund counter-drone work outside the conventional Phase I/II structure, and it changes how small businesses can engage with the Navy's most urgent capability gap.
Read articleThe Department's FY26 SBIR/STTR Release 3 opened June 24 with roughly 37 topics across DARPA, the Navy, the Air Force, and the defense components, all closing July 22. The compressed four-week window is unforgiving, but the bigger mistake founders make is treating every component the same. Here is how to read the release, the eligibility rules that disqualify good companies, and why the component you target matters more than the topic you pick.
Read articleThe memorandum of agreement was signed August 4 and 5, disclosed by House appropriators on September 3, and runs through 2036. It names no dollar figure. Here is what is actually established, what is still speculation, and what researchers holding or planning NIAID biodefense awards should do before September 30.
