About the company
Seahorse Defense Supply, LLC, a women-owned small business based in Lilburn, Georgia, supplies mechanical, electrical, and electronic components to the Defense Logistics Agency, the U.S. Coast Guard, and the Department of the Navy as a prime contractor. The company holds SBA certifications as a Women-Owned Small Business, Economically Disadvantaged Women-Owned Small Business, and is minority-owned (Subcontinent Asian American-owned). Seahorse competes predominantly on full-and-open and Total Small Business set-aside procurements, with the latter appearing across roughly 30–40% of recent awards.
Seahorse's capability portfolio spans valve assemblies, hose and tubing fittings, pumps, filters, gaskets, seals, engine components, electrical connectors, power supplies, and industrial equipment supporting marine, aviation, and land platforms. Recent representative prime awards include a $343.970 million delivery order from Defense Logistics Agency Land and Maritime for power supply components (March 2026), a $198.033 million delivery order for a pressure plate assembly (April 2026), and a $135.447 million delivery order for counterbalance weights (May 2026). Smaller tactical orders flow routinely from the Coast Guard for marine engine spares—such as a $92.359 million purchase order for control monitor units (February 2026) and a $49.291 million purchase order for Honda marine generator engine accessories for 29-foot rigid-hull boats (February 2027)—alongside Navy awards for maintenance kits, radiators, and specialized fastening components.
Customer concentration is pronounced. Defense Logistics Agency Land and Maritime dominates: 699 awards (37% of the total footprint) with $26.4 million combined potential value. The U.S. Coast Guard ranks second with 274 awards and $9.1 million in combined value, followed by Navy Naval Supply Systems Command with 178 awards and $8.8 million. Together, these three customers account for 76% of all awards. The top five customers by potential value cover 77% of combined dollars, with Army Materiel Command Detroit Arsenal contributing $6.4 million across seven awards—a significant outlier in dollar per-award terms, indicating large-dollar transactional buys from that customer relative to its frequency.
Seahorse holds ten single-award indefinite-delivery contracts with DLA Land and Maritime, each valued at $350,000 ceiling, running one-year terms or until ceiling exhaustion. These cover specific components: electrical connectors (NSN 5935015660178), internal combustion pistons (NSN 2815123585987), RF filters (NSN 5915016513818), optoelectronic couplers (NSN 5980123758396), power supply assemblies (NSN 6130017235080), parts kits and tie rods (NSN 2530015194167), light-emitting diodes (NSN 5980015704657), power supplies (NSN 6130016243654), and packing assemblies (NSN 5330014725886). Task order activity under these vehicles runs transactional patterns—typically three to eight orders per vehicle per year—reflecting component replenishment rather than large program buys. The top five named IDVCs by task order count show 8, 5, 4, 4, and 3 task orders respectively, with aggregate potential values under $400 thousand across the group, confirming the fragmented, repetitive-supply nature of DLA Land and Maritime work.
Top NAICS categories reflect this specialization: Other Engine Equipment Manufacturing (113 awards), All Other Miscellaneous General Purpose Machinery Manufacturing (79), Bolt/Nut/Screw/Rivet/Washer Manufacturing (55), Hardware Manufacturing (50), and Other Electronic Component Manufacturing (50). Top PSC codes align: Valves Nonpowered (57 awards), Hardware Commercial (51), Power and Hand Pumps (50), Hose/Pipe/Tube Fittings (49), and Engine Air and Oil Filters (45). This distribution underscores Seahorse's positioning as a component-level supplier rather than a systems integrator or service provider.
Activity has grown year over year—140 awards in 2023 to 322 in 2025—then contracted to 214 in 2026 and 1 in 2027 (early data). The recompete cliff over the next twenty-four months carries modest exposure: 40 awards with combined potential value of $1.9 million reaching ultimate completion. Combined potential value across the entire footprint is $73 million, with $53.6 million obligated (73%), indicating strong invoicing velocity. Seahorse operates as 100% prime—no subcontract awards are listed in the source—and does not list any named teaming relationships or sub activity, positioning the company as a direct supplier to federal agencies rather than a system prime or sub-tier provider.
