Mentis Sciences Inc.

Mentis Sciences Inc., doing business as MSI, is a small business manufacturer of advanced aerospace and defense components and specialized high-temperature materials that operates predominantly as a federal prime contractor (98% of awards) under total small business set-asides on SBIR and STTR research and development efforts and full-and-open production contracts. Based in Warner, New Hampshire, MSI is a for-profit manufacturer and engineering services provider specializing in materials science and aerospace component manufacturing for defense applications, with recent activity concentrated in phases II and III of the Small Business Innovation Research program.

MSI's customer base is heavily concentrated in the Defense Logistics Agency and the Department of Defense. The top five funding agencies account for 71% of awards by count and 90% by potential value: Defense Logistics Agency Troop Support leads with 20 awards worth $30.8 million in combined potential value, followed by the Missile Defense Agency with 15 awards ($17.4 million), the Naval Air Warfare Center with 7 awards ($11.6 million), Naval Sea Systems Command with 2 awards ($7.3 million), and DLA Aviation with 19 awards ($4 million). The divergence between volume rankings (DLA Aviation's high award count but lower dollar value) and value rankings reflects MSI's dual posture: numerous small-dollar delivery orders for labyrinth seal production and components, paired with larger SBIR Phase II and Phase III definitive contracts for materials development and manufacturing process improvements. MSI holds a cornerstone single-award indefinite delivery contract with DLA Aviation valued at $2 million through February 2028 for the supply of labyrinth seals critical to military aviation systems; eight delivery orders have been issued under this IDC since February 2023, ranging from approximately $115,181 to $255,428 per order with cumulative obligations near $1.19 million.

MSI's capability portfolio centers on high-temperature materials, hypersonic technologies, advanced composites, and ceramic matrix composite manufacturing for aerospace applications. Representative work includes a $7.9 million SBIR Phase III definitive contract awarded by DLA Troop Support in September 2024 for in-situ inspection of ceramic matrix composites during manufacture under the Air Force's X20.3 Commercial Solutions Opening; a $3.27 million Phase III contract from DLA Troop Support in February 2025 for hypersonic radome and aperture manufacturing improvements; a $1.94 million SBIR Phase II contract from DLA Troop Support in September 2023 for source development and qualification testing of C-5 duct assemblies; a $1.8 million Phase II contract from DLA Troop Support in July 2026 extending MSIL13XX material development work originating from an earlier Air Force SBIR; and a $1.1 million SBIR Phase II contract from DLA Troop Support in October 2021 for high-temperature structural resistive foams development. Production work includes a $488,250 purchase order from DLA Aviation in March 2025 for support assemblies (40 units), a $99,377 SBIR Phase I contract from DLA in August 2024 for F/A-18 component reverse engineering and source development, and sustained labyrinth seal supply through DLA Aviation delivery orders. MSI also executes a small volume of SBIR and STTR Phase I awards for early-stage research, including a $99,966 DLA Phase I contract in September 2022 and a $99,964 STTR Phase I contract in July 2023 for thermal protection systems commercialization.

Activity has remained relatively flat at six to seven awards per year across the past five years (2022–2026), with 95 total awards in the source dataset yielding $79.2 million in combined potential value. Four awards carrying combined potential value of $6.7 million reach ultimate completion within the next twenty-four months, creating moderate recompete exposure on development and component-qualification efforts. MSI's set-aside posture recurs consistently across its prime footprint: the vast majority of SBIR and STTR work flows under total small business set-asides, while production delivery orders (particularly labyrinth seal supply) run full-and-open under the DLA Aviation IDC. Top NAICS concentrations are R&D in physical and engineering sciences (39 awards combined across two related codes) and aircraft engine and engine parts manufacturing (18 awards), with top PSCs tracking to gas turbines and jet engines components (18 awards) and defense R&D services (20 awards combined across categories). MSI maintains no material subcontract footprint (2% of awards) and no visible teaming relationships in the source data.
