Marine Electric Systems Inc.

Marine Electric Systems Inc., doing business as Mesys, manufactures precision electronic components, sensors, valves, and maritime monitoring devices for the U.S. Department of Defense as a prime contractor (100% of recent awards), with headquarters in South Hackensack, New Jersey. The company is a for-profit corporation that competes predominantly in full-and-open federal procurements, though a subset of its awards carry total small business set-aside designations. Mesys operates as a parent entity with three named subsidiaries—MES Weldtech Inc., Rectico Inc., and Aerospace Industries LLC—each also manufacturers of goods.

Mesys' core capability centers on specialized maritime electronics: salinity sensors and detection cells, alarm and control modules, proximity switches, circuit card assemblies, power supplies, transformers, gate valves, and related monitoring equipment. Representative recent work includes a $207.5 million delivery order (awarded December 2025) from DLA Aviation for salinity sensors under a total small business set-aside, a $154 million delivery order (March 2025) from DLA Aviation for alarm modules supporting Ohio-class submarine programs under a single-award indefinite delivery contract, and a $167.5 million purchase order (September 2025) from Naval Sea Systems Command for salinity detector cells designated for Puget Sound Naval Shipyard. Across its portfolio, Mesys has delivered recurring orders of salinity cells, indicator cells, and alarm modules to support fleet maintenance and submarine operations.

Customer concentration sits heavily with the Defense Logistics Agency and Naval Supply Systems Command. The top five customer organizations by award count account for 77% of recent awards: DLA Land and Maritime leads with 659 awards and $17.6 million combined potential value; Naval Supply Systems Command follows with 373 awards and $11.6 million; DLA Aviation holds 261 awards valued at $21.1 million; the Navy unspecified accounts for 172 awards; and DLA Troop Support Construction and Equipment carries 170 awards worth $9.7 million. By dollar value, DLA Aviation dominates at 27% of portfolio potential value, anchored by two indefinite delivery contracts and recurring high-value delivery orders for salinity sensors. The Navy's Naval Air Warfare Center represents a concentration point at $10 million across just two awards.

Mesys holds five primary parent indefinite delivery contracts that enable task order issuance: a $5 million single-award blanket purchase agreement with Naval Air Warfare Center (awarded May 2025, running through May 2030) covering broad electronic components; a $627.8 thousand IDC with DLA Aviation (January 2025) for alarm modules supporting Ohio-class submarines; a $1.9 million total small business set-aside IDC with DLA Aviation (September 2022) for salinity sensors; a $250 thousand IDC with DLA Aviation (September 2022) for salinity indicator cells; and additional vehicles through DLA Land and Maritime and DLA Construction and Equipment. Task order volume under these vehicles ranges from eight to fifteen per contract.

Activity has experienced volatility over the past five years—122 awards in 2022, declining to 78 in 2024, then rebounding to 105 in 2025. Eleven awards carrying combined potential value of $566 thousand face ultimate completion within the next twenty-four months, representing modest recompete exposure. Mesys' product portfolio skews heavily toward chemical analysis instruments (366 awards), switches (208 awards), water distillation and marine equipment (175 awards), flow and level measuring instruments (166 awards), and nonpowered valves (128 awards), reflecting the maritime-defense electronics and instrumentation focus.

In its subcontractor role, Mesys supplies resistivity sensors to Hamilton Sundstrand Corporation, salinity cells to Huntington Ingalls Inc., and fire control switchboard and telephone system components to Electric Boat Corporation—aligning with its established position as a component supplier to major shipbuilders on submarine and naval vessel programs. The subcontract footprint remains minimal (eight awards, less than one percent of the portfolio) compared to its dominant prime position.

Mesys operates without SBA certifications or socioeconomic set-aside designations as a core identity—most awards are full-and-open competitive, though recurring small business set-aside designations appear on specific DLA and Naval Supply Systems Command vehicles, suggesting qualification and periodic reservation on defined contract vehicles. The company has maintained a long-standing relationship with defense logistics entities, with award records dating to 1981, positioning it as an established supplier of mission-critical maritime monitoring and control electronics to naval operations and fleet readiness.
