Mentis Sciences Inc.

Mentis Sciences Inc., doing business as MSI, a small business manufacturer and engineering services provider based in Warner, New Hampshire, delivers advanced aerospace and defense components, high-temperature materials, and specialized R&D services to the Department of Defense as a prime contractor on SBIR and STTR programs (98% of recent awards). MSI operates under total small business set-asides on most of its research contracts, with full-and-open competition on its production delivery orders for labyrinth seals and support assemblies.

MSI's customer base concentrates heavily on defense agencies. The top five funding agencies account for 71% of recent awards by count and 90% by combined potential value, led by the Defense Logistics Agency Troop Support (20 awards, $30.8 million), the Missile Defense Agency (15 awards, $17.4 million), and the Naval Air Warfare Center (7 awards, $11.6 million). DLA Aviation ranks fourth by potential value but second by award count (19 awards, $4.1 million), reflecting a high-volume, lower-dollar delivery order stream against MSI's $2.0 million single-award indefinite delivery contract for labyrinth seal supply running through February 2028.

MSI's capability portfolio centers on three streams: SBIR and STTR Phase I, II, and III contracts for advanced materials research, hypersonic technologies, and aerospace component development; production delivery orders for specialized aviation components; and engineering services for source development and reverse engineering of defense systems. 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 X20.3 Commercial Solutions Opening; a $3.3 million SBIR Phase III contract for hypersonic radome and aperture manufacturing (awarded February 2025, completion February 2027); a $1.94 million SBIR Phase II definitive contract with DLA Troop Support for source development and qualification testing of C-5 duct assemblies (awarded September 2023, extended through June 2026); and multiple delivery orders under the $2.0 million DLA Aviation indefinite delivery contract, with individual orders valued between $115,181 and $255,428 for labyrinth seal supply. A $1.8 million research and development definitive contract was awarded by the Naval Air Warfare Center on April 11, 2024, under a total small business set-aside. Most recently, MSI was awarded a $1.1 million SBIR Phase II definitive contract by DLA Troop Support on April 9, 2026, for reverse engineering and source development supporting materiel management programs, with completion scheduled for April 2028.

Activity has remained flat at approximately seven awards per year across 2022 through 2025, with one award recorded in 2026. Eight awards with combined potential value of $17.4 million carry ultimate completion dates within the next twenty-four months, creating recompete exposure. The single-award indefinite delivery contract with DLA Aviation (established February 2023, running through February 2028) anchors MSI's production revenue stream and has generated eight delivery orders to date, with the most recent issued in November 2025. MSI operates as a prime contractor on the vast majority of its awards; sub-award participation is minimal (2% of total awards). Top NAICS categories reflect the portfolio composition: Research and Development in Physical, Engineering, and Life Sciences (39 awards combined across two related NAICS codes), Aircraft Engine and Engine Parts Manufacturing (18 awards), and Other Services to Buildings and Dwellings (8 awards). Top PSC codes track similarly, with Gas Turbines and Jet Engines, Aircraft, Prime Moving; and Components (18 awards) and National Defense R&D Services spanning multiple research-focus categories across 33 awards.
