American Ceramic Technology Inc.

American Ceramic Technology Inc., a self-certified small disadvantaged business and women-owned manufacturer based in Poway, California, supplies specialized radiation shielding materials and components to the Department of the Navy as a prime contractor, with nearly all recent work (87 of 89 awards, 98% of the footprint) routed through Naval Sea Systems Command. The company is structured as a for-profit Subchapter S corporation and operates predominantly in the small-business set-aside posture, with awards split between Total Small Business set-asides and full-and-open competitive procurements.

American Ceramic Technology manufactures flexible silicone radiation shielding materials incorporating tungsten powder (approximately 95% tungsten by weight) and silicon polymer matrices to meet naval nuclear propulsion application requirements. Representative recent work includes a $307,125 firm fixed-price purchase order (March 20, 2026) for 65 units of tungsten-impregnated silicon polymer CDM outsert shielding components manufactured to Drawing 2370.2-7445, each with minimum density of 7 grams per cubic centimeter and a Tenth-Value Layer of 2.00 inches or greater, awarded by NAVSEA under an 8(a) sole-source women-owned small-business designation; a $248,630 Total Small Business set-aside purchase order (September 18, 2025) for tungsten-impregnated silicon polymer shielding components for Norfolk Naval Shipyard's Reactor Servicing department; and a $438,000 firm fixed-price definitive contract (August 14, 2024) for magnetic tungsten shielding for Portsmouth Naval Shipyard. The source indicates over twenty prime awards since 2021 totaling approximately $1.4 million directed to naval nuclear infrastructure applications.

Customer concentration is extreme and narrow: Naval Sea Systems Command accounts for 87 of 89 total awards and $5.9 million of combined potential value. The source documents a single outlier—a $7 million award from the Army Corps of Engineers Engineer Research and Development Center and a $52,000 award from the Air Force Space Command—leaving NAVSEA's share at roughly 98% of potential value. Recent activity has been modest: one award in 2026, four in 2025, and four in 2024, suggesting a business anchored to recurring NAVSEA purchase orders for shielding replenishment rather than growth-stage pipeline. Combined potential value across all 89 awards stands at $12.9 million, with $7.6 million obligated to date (59% execution).

The vendor's subcontractor footprint is minimal (2 of 89 awards, or 2%)—both recent sub awards through Huntington Ingalls Inc. for shielding components and pipe assemblies supporting CVN 75 Refueling and Complex Overhaul (RCOH) advance planning (June and August 2025). Product category concentration aligns tightly with the radiation-shielding mission: top NAICS include All Other Plastics Product Manufacturing (30 awards) and All Other Rubber Product Manufacturing (12 awards); top PSCs include Plastics Fabricated Materials (33 awards) and Rubber Fabricated Materials (13 awards). The vendor operates under U.S. Patent 9,666,317 B2 covering its tungsten-impregnated silicone formulation, cited in multiple awards as a protected design requirement.
