DTRA SBIR research for remote UAS-based X-ray device assessment in CBRNE environments

**Buyer:** Defense Threat Reduction Agency (DTRA)
**Posted:** November 04, 2026

**NAICS:** 541715, 334511, 334517

DTRA is soliciting SBIR research proposals, including a topic for stand-off UAS-based X-ray assessment of suspected devices in CBRNE environments.
- Government buyer: Department of War (DoW), Defense Threat Reduction Agency (DTRA), DTRA SBIR/STTR Program.
- Focus topic: DTR27BZ02-NV002, Remote UAS-based X-Ray for Device Assessment in CBRNE Environments.
  - Develop cooperating unmanned aircraft system (UAS) platforms carrying X-ray transmitters and detectors to image suspected devices without personnel or ground teams near the threat.
  - The intended capability should produce diagnostic images and help identify internal fuse features, including in chemical, biological, radiological, nuclear, and explosive environments.
- Development progression: Phase I covers system design and computer-based performance modeling; Phase II advances to a working prototype; later development may address multi-site, swarming operations and rapid, on-location image results.
- Notable technical challenges include lightweight airborne X-ray equipment, motion-compensated image reconstruction, diagnostic image quality at greater standoff, extracting fuse-function information, and handling contaminated hardware.
- The broader release also covers adaptive subsurface-hazard sensor tasking, blast-injury model validation, domestic scintillator precursor production, and scalable growth of large-format CZT crystals, in addition to UAS-based EOD aiming and X-ray assessment.
- Funding ceilings: Phase I base amount up to $250,000, excluding TABA; TABA is capped at $6,500. Follow-on Phase II is limited to 24 months and $1,500,000, excluding TABA; Phase II TABA is capped at $50,000.
- No commercial OEMs or vendors, product quantities, or part numbers are identified.

### Description

This DTRA SBIR topic seeks proposals related to remote UAS-based X-ray for device assessment in CBRNE environments. It is part of the DoW SBIR 2027 BAA, Release 2. Phase I proposals must be submitted through DSIP; the technical volume is limited to 20 pages, and the base amount must not exceed $250,000, excluding TABA. The Phase I project duration is seven months, and proposals are due February 3, 2027.
