H3D Inc.

H3D Inc., a minority-owned, Asian-Pacific American-owned manufacturer based in Ann Arbor, Michigan, designs and builds advanced radiation detection systems including cadmium zinc telluride (CZT) gamma-ray detectors, imaging spectrometers, and neutron detection modules for federal defense and national security missions, operating predominantly as a prime contractor (83% of recent awards) with occasional subcontract roles on R&D programs.

H3D competes in both full-and-open and small-business set-aside categories. Recent prime awards include a $1.15 million SBIR Phase II cost-plus-fixed-fee contract from the Defense Threat Reduction Agency for commercialization of perovskite gamma-ray sensors (awarded April 18, 2025, ultimate completion April 17, 2027); a $3.16 million firm fixed-price purchase order from Naval Information Warfare Systems Command for 37 T410 detector packages with integrated data collection, imaging reconstruction, and isotope identification software (awarded December 23, 2023); a $482,400 small-business set-aside purchase order from the Department of Justice Federal Bureau of Investigation for gamma-ray detection services (awarded March 16, 2023); and a $929,812 cost-plus-fixed-fee contract with DTRA for coded aperture masks supporting 3D radiation hazard mapping under a broad agency announcement (awarded November 1, 2021). The source also documents a $2.55 million cost-plus-fixed-fee contract from DHS's Countering Weapons of Mass Destruction office for prototype gamma-only radioisotope identification devices using thallium bromide semiconductor technology, though a subsequent modification de-obligated $1.13 million following a termination settlement. Product lines span the T410 gamma-ray imager package, the M400 and A401 detector packages, and CZT-based detection modules with hardware and software integration.

Customer concentration skews heavily toward defense and threat-detection agencies. The Defense Threat Reduction Agency dominates by award count (16 awards, $6.1 million combined potential value), followed by the Department of Energy Office of Science (13 awards, principal focus on grant funding rather than contracts). A critical outlier surfaces in the potential-value ranking: the Department of the Army Acquisition Support Center Joint PEO Chemical and Biological Defense carries only 3 awards but anchors $8.28 billion in combined potential value — a placeholder ceiling on what appears to be a large-scale procurement or requirements vehicle rather than executed orders. The Department of the Navy Information Warfare Systems Command (2 awards, $3.2 million), Department of Homeland Security Countering Weapons of Mass Destruction (1 award, $2.5 million), and Naval Sea Systems Command (3 awards, $1.7 million) complete the active customer set. The two rankings diverge markedly: DTRA represents genuine, executed work volume; Army's outsized dollars reflect a different contracting posture. Seventy-one percent of recent awards cluster in the top five customer agencies.

H3D's prime contract vehicle footprint is light. The source names the Information Analysis Center Multiple-Award Contract and Joint Enterprise Research Development Acquisition and Production-Procurement as parent vehicles with task order activity, though detail is minimal. The vendor's award portfolio is driven by direct purchase orders and standalone SBIR/R&D contracts rather than GWAC or governmentwide IDIQ seats.

Activity has grown substantially year over year—two awards in 2022, six in 2023, seven in 2024, and eleven in 2025—indicating sustained customer demand for specialized detection hardware. Three awards (combined potential value $1.2 million) face ultimate completion within the next twenty-four months and therefore carry recompete risk. The recent peak in 2025 activity reflects a slate of DOE Office of Science project grants awarded July 8, 2025, including four separate $206,500 grants for radiation monitoring robots, fresh nuclear fuel imaging, subpixel semiconductor radiography sensors, and uranium enrichment measurement using CdZnTe, plus one $181,292 grant for large-volume CdZnTe detector development.

H3D operates as a prime contractor on most work but maintains selective subcontractor relationships. In its sub role, H3D has delivered autonomous and automated systems engineering and design services to Leidos on a February 2024 Naval Information Warfare Center Pacific support task, and provides general supplies and warranty services (gamma camera warranty extensions and unspecified goods) to Pantexas Deterrence LLC on the Pantex Plant management and operation contract and to the Idaho Cleanup Project prime contractor. H3D also subcontracts to academic institutions: it appears as a sub-recipient on grant work led by Pennsylvania State University (multiple "Interaction of Ionizing Radiation with Matter University Research Alliance" collaborations, 2024–2026) and the University of Maryland, Baltimore (3D prompt gamma imaging for proton beam dose verification, 2024–2025).

The Service Contract Inventory dataset, which covers service contracts above $150,000 and excludes goods, products, and micro-purchases, captures minimal H3D activity: $528 thousand in invoiced SCI-reportable revenue across FY2023–FY2024, with 1.2 FTEs reported in FY2024. This narrow SCI footprint reflects H3D's primary business model as a manufacturer and goods provider rather than a labor-hour service contractor. Government-paid hourly rates on the two SCI records run a median of $165.39/hour, with 10th percentile at $134.21/hour and 90th percentile at $196.57/hour. Across SCI-reportable prime contracts, H3D performed 0% of hours through subcontractors, indicating in-house delivery on service-contract work when captured in SCI. The SCI view is incomplete: it excludes the bulk of H3D's federal business, which consists of product sales and R&D deliverables on firm fixed-price purchase orders and SBIR contracts.

H3D's core NAICS footprint reflects its dual character as both a research organization and a hardware manufacturer. Research and Development in the Physical, Engineering, and Life Sciences dominates (12 awards), followed by Other Measuring and Controlling Device Manufacturing (7 awards), Analytical Laboratory Instrument Manufacturing (3 awards), and Research and Development in Biotechnology (3 awards). PSC alignment emphasizes Hazard-Detecting Instruments and Apparatus (6 awards) and defense-related R&D categories (National Defense R&D Services, R&D Defense Other, and R&D Defense System tags across 10 combined awards).
