DTRA SBIR/STTR research solicitation for subsurface hazard detection and related defense technologies

**Buyer:** Defense Threat Reduction Agency (DTRA)
**Posted:** November 07, 2026
**Respond By:** January 06, 2027
**Identifier:** DTR27BZ02-NV003
**NAICS:** 541715, 541713, 541360

The Defense Threat Reduction Agency is seeking SBIR/STTR research proposals under its Department of War 2027 Release 2 solicitation, including work on adaptive sensor routing for subsurface hazard detection.
- **Government buyer:** Defense Threat Reduction Agency (DTRA), Department of War; DTRA SBIR/STTR Program.
- **Primary topic:** Develop a dynamic system that adaptively tasks and routes sensors to detect subsurface hazards.
- **Other topics in the solicitation attachment:** Remote UAS-based precision aiming for EOD render-safe operations in CBRN environments; remote UAS-based X-ray device assessment; battlefield blast-injury model validation; domestic production of high-purity scintillator precursor materials; and scalable domestic growth of large-format pixelated CZT crystals.
- **Work requested:** Phase I feasibility, design, analysis, and proof-of-principle research; Phase II follow-on prototyping, integration, testing, validation, or scale-up.
- **Funding and duration:** Phase I is limited to seven months and a $250,000 base amount, excluding TABA (capped at $6,500). Phase II is limited to 24 months and $1,500,000, excluding TABA (capped at $50,000). Phase I awardees may submit Phase II proposals.
- **Notable technical requirements across topics:** Explainable edge AI, remote operation in CBRN environments, rigorous model validation, high-purity and reproducible materials, and resilient domestic supply chains.
- **Submission:** Proposals are submitted through the Defense SBIR/STTR Innovation Portal (DSIP). The notice identifies CMMC Level 1.
- **OEMs, vendors, products, and quantities:** No commercial OEMs or vendors, product part numbers, or purchase quantities are identified; this is a research and development opportunity.

### Description

The Defense Threat Reduction Agency (DTRA) SBIR topic is titled “Dynamic Sensor-Tasking and Routing System for Subsurface Hazard Detection.” Proposals are invited under eligible Phase I, Phase II, and Sequential Phase II phases, and must be submitted through the DoW SBIR/STTR Innovation Portal. Phase I proposals have a seven-month duration and a base funding limit of $250,000, excluding Technical and Business Assistance (TABA). The response deadline is February 3, 2027, at 13:00 UTC.
