About Materials Sciences LLC
Materials Sciences LLC, a small business subsidiary of Seemann Composites LLC, delivers advanced composite materials research, engineering, thermal management, and additive manufacturing services to the Department of Defense as a prime contractor operating predominantly under Total Small Business set-asides. The company is headquartered in Horsham, Pennsylvania and competes almost exclusively in full-and-open federal procurements reserved for small businesses; nearly all recent prime awards carry Total Small Business set-aside designations.
Materials Sciences operates across multiple NAICS and PSC categories centered on defense R&D: Engineering Services (90 awards), Research and Development in the Physical, Engineering, and Life Sciences (52 awards), and Applied Research/Exploratory Development across National Defense contexts. Recent representative work includes a $2.0 million Phase II contract from Naval Sea Systems Command for Space-Based Infrared System High (SBIRS High) composite materials development (awarded January 2026, ultimate completion January 2029), a $1.79 million cost-plus-fixed-fee contract for design-for-additive-manufacturing risk toolset development on SBIRS High (January 2025, completion January 2028), a $1.78 million effort on environmental coating materials for Radar Absorbent Material tiles for DDG-1000 guided-missile destroyers (September 2024, completion September 2027), and a $739,583 Air Force Research Laboratory Phase II award for an analysis tool predicting bolted composite-metallic hybrid joint behavior (July 2022, completed August 2024). The company also holds an active $99,994 Defense Logistics Agency SBIR Phase I contract for domestic, low-cost pitch carbon fiber development for high-temperature applications (awarded August 2025, completion February 2026).
Customer concentration is heavily Navy-driven. Naval Sea Systems Command dominates the portfolio with 111 awards valued at $160.1 million combined potential value, representing approximately 60% of all awards and 94% of the combined potential-value ranking when the top five customers are aggregated. The Department of the Army Materiel Command Aviation and Missile Life Cycle Management Command ranks second with 21 awards valued at $61.2 million. Army Research, Development and Engineering Command, Air Force Research Laboratory, and Naval Air Systems Command Naval Air Warfare Center round out the top five. The 68% of awards covered by the top five agencies underscores Materials Sciences' concentration in Navy-dominated R&D, particularly composite materials and advanced manufacturing innovation supporting SBIRS High and submarine programs.
Materials Sciences executes work under five primary Navy IDIQs: Indefinite Delivery Contract N6554008D0011 (29 task orders, $24.6 million combined potential value), Indefinite Delivery Contract N6554015D0011 (20 task orders, $23.3 million combined potential value), Indefinite Delivery Contract N6092183C0155 (10 task orders), Indefinite Delivery Contract N6092186C0236 (9 task orders), and Indefinite Delivery Contract N6660408D0034 (9 task orders, $7.8 million combined potential value). These vehicles anchor the company's recurring task-order revenue stream.
Activity has remained modest and stable, with two awards in 2026 (year-to-date), nine in 2025, five in 2024, five in 2023, and ten in 2022. Seven awards with ultimate completion dates in the next twenty-four months carry combined potential value of $18.7 million, creating moderate recompete exposure. As a subcontractor, Materials Sciences provided composite material consulting under a Manufacturing Technology Composites Manufacturing Center sub-award (September 2025, prime not identified), impeller erosion boots to Science Applications International Corporation for Naval Surface Warfare Center Panama City air-cushion vehicle hull development (January 2025), and program support services to Serco-Ips Corporation on Navy PMS 377 landing craft and logistics programs (May 2023). Sub-work is minimal—only four sub-awards across the portfolio, representing 1% of total awards.
Seemann Composites LLC, the parent company, is a small disadvantaged business holding indefinite delivery contracts valued over $300 million with Naval Sea Systems Command for composite components and engineering support on COLUMBIA and VIRGINIA Class submarine programs. Materials Sciences' focused R&D and advanced manufacturing portfolio complements the parent's production and systems-integration work on naval vessel programs, positioning the corporate family across both innovation and production streams for Navy modernization.
