DTRA SBIR research topics for UAS, hazard sensing, blast modeling, and domestic materials production

**Buyer:** Defense Threat Reduction Agency (DTRA)
**Posted:** November 07, 2026
**Respond By:** January 06, 2027
**Identifier:** DTR27BZ02-NV001
**NAICS:** 541715, 541713, 541330, 334511

DTRA is seeking small-business research proposals for six defense technology topics, including UAS-based precision aiming for render-safe operations in CBRN environments.
- **Government buyer:** Defense Threat Reduction Agency (DTRA), Department of War (DoW), DTRA SBIR/STTR Program.
- **Topics sought:** UAS-based EOD precision aiming in CBRN environments; remote UAS-based X-ray assessment of devices; adaptive sensor tasking and routing for subsurface hazard detection; validation of battlefield blast-injury models; domestic production of high-purity scintillator precursor materials; and scalable domestic growth of large-format pixelated CZT crystals.
- **Work sought:** Phase I feasibility, design, analysis, and proof-of-principle research, with follow-on Phase II work potentially involving prototypes, integration, testing, validation, and scale-up. The broader DoW SBIR announcement also includes Direct-to-Phase-II opportunities, subject to topic-specific requirements.
- **Notable requirements:** Remote operation in CBRN conditions, explainable edge AI, rigorous model validation, reproducible high-purity materials, and resilient domestic supply chains.
- **Funding and performance:** Phase I is generally seven months for these DTRA topics, with a $250,000 base ceiling excluding TABA (TABA capped at $6,500). Phase II may run up to 24 months, with a $1,500,000 ceiling excluding TABA (TABA capped at $50,000). The broader announcement describes Phase I as generally 6–12 months and Phase II as generally 24 months.
- **OEMs and vendors:** No commercial OEMs, vendors, products, part numbers, or purchase quantities are identified.

### Description

This Defense Threat Reduction Agency SBIR topic seeks proposals for UAS-based precision aiming to render a device safe in CBRN environments. The topic is part of the DoW SBIR 2027 BAA, Release 2, and is listed as pre-release. Proposals are due December 18, 2026. DTRA instructions specify Phase I work with a seven-month duration and a base amount not exceeding $250,000, excluding TABA.
