Defense Manufacturers Inc.

Defense Manufacturers Inc., a veteran-owned small business manufacturer based in Somersworth, New Hampshire, produces precision-engineered stave damping components, acoustic control materials, and vibration mitigation assemblies as a prime contractor exclusively for the U.S. Navy, with 100% of recent awards concentrated on Naval Sea Systems Command and subordinate Navy commands.

Defense Manufacturers Inc. is a for-profit manufacturer specializing in naval acoustic stealth and vibration mitigation technologies. The company carries veteran-owned business (VOSB) designation and competes across both Total Small Business set-asides and full-and-open procurements with NAVSEA, though the majority of its footprint appears to be full-and-open firm fixed-price purchase orders. The vendor operates primarily from its Somersworth headquarters, with secondary performance locations in Portsmouth, Virginia. Across the source data spanning back to 1992, Defense Manufacturers Inc. has received 342 prime awards with a combined potential value of $2 million and combined dollars obligated of $2.3 million.

Customer concentration is extreme: Naval Sea Systems Command alone accounts for 257 awards (75% of the prime footprint) carrying $1.4 million in combined potential value, followed by Naval Supply Systems Command (57 awards, $389 thousand) and U.S. Pacific Fleet Forces (17 awards, $139 thousand). These three Navy entities represent 99% of awards by count and 100% of combined potential value. The vendor serves no significant civilian agencies and has negligible DoD customer diversity beyond Navy commands.

The product portfolio consists of stave dampening components in various configurations (CRES stave damping, stave module assemblies, axial stave dampening materials, damping staves, hoses, and sound-control assemblies), all purpose-built for submarine and surface ship acoustic signature management. Recent representative awards include a $33.5 thousand Total Small Business set-aside from NAVSEA on January 29, 2026 for stave dampening components with completion targeted for February 5, 2026; an $11.9 thousand Total Small Business set-aside from NAVSEA on April 24, 2025 for stave damping assemblies; a $19.2 thousand Total Small Business set-aside from NAVSEA on October 28, 2024 for stave damping components; and a $16.6 thousand non-set-aside purchase order from NAVSEA on September 26, 2023 for stave dampening materials including hoses.

Activity has remained episodic: seven awards in 2022, four in 2023, nine in 2024, and eleven in 2025. The vendor operates exclusively in the prime capacity with no subcontract footprint in the source data. Individual contract values historically range from $1.9 thousand to $33.5 thousand, with the majority falling in the $4 thousand to $15 thousand band, reflecting NAVSEA's procurement pattern for specialized components sourced through small-quantity purchase orders rather than larger platform contracts. Defense Manufacturers Inc. does not sit on government-wide IDIQs, GWACs, or multi-agency BPAs; all awards are direct purchase orders issued by Navy commands. The vendor's entire customer exposure rests on NAVSEA's ongoing submarine and surface ship maintenance and modernization schedules, creating significant concentration risk in a single program office and single service.
