About the company
L.M. Gill Welding & Manufacturing, L.L.C., doing business as LM Gill Welding & Manufacturing LLC, manufactures precision-welded and machined naval and defense components including valves, hose assemblies, adapters, and specialized fittings as a prime contractor (75% of awards) to the Defense Logistics Agency and Naval Sea Systems Command, competing predominantly under full-and-open and small business set-aside solicitations.
L.M. Gill is a for-profit limited liability partnership based in Manchester, Connecticut, where all work is performed. The vendor qualifies as a small business and has competed under Total Small Business set-asides on approximately 40 percent of its historical awards; the remaining 60 percent of recent prime work carries no set-aside designation, indicating full-and-open competitive posture on the majority of awards. Primary NAICS categories reflect manufacturing depth: Rubber and Plastics Hoses and Belting Manufacturing (65 awards), Ship Building and Repairing (42 awards), and Industrial Valve Manufacturing (31 awards). Top product codes center on hose and flexible tubing (66 awards), nonpowered valves (42 awards), and hose and pipe fittings (29 awards).
Customer concentration is extreme. The Defense Logistics Agency Land and Maritime accounts for 135 of 240 total awards (56% of volume) and $6 million of the $7 million combined potential value across the portfolio — a 99% concentration in a single customer across prime and sub work combined. The Department of the Navy Naval Sea Systems Command represents the second-tier customer at 61 awards and $634 thousand potential value. All other federal agencies combined account for fewer than 50 awards and sub-$100,000 combined value. This concentration reveals a specialized supplier model: L.M. Gill operates almost entirely within the DLA Land and Maritime supply system for naval and maritime equipment.
Activity shows a steady footprint at 41–44 awards annually from 2022 through 2024, dropping sharply to 13 awards in 2025 and one award year-to-date in 2026 — a trajectory consistent with purchase-order volatility rather than growth. Only one prime award carries an ultimate completion date within the next twenty-four months, with a combined potential value of $290 thousand — minimal recompete exposure.
In its subcontractor role, L.M. Gill supplies welded and machined components to Electric Boat Corporation on submarine construction programs, including SSN 804, SSN 814, and SSN 815 long-lead material and construction work, and to Huntington Ingalls Inc. on CVN 80/81 carrier construction. Subcontract work centers on specialized naval hardware such as flanges, fasteners, and component assemblies supporting vessel construction and modernization rather than on the hose and valve assemblies that dominate the prime footprint.
Representative prime awards include a $792 thousand Total Small Business set-aside from DLA Land and Maritime for 57 units of ball valves (September 2024), a $799 thousand Total Small Business flow control valve order from the same customer (September 2024), a $289 thousand full-and-open purchase order for ball valves from DLA Land and Maritime (March 2026), and a $196 thousand pressure tank order from DLA Troop Support Construction and Equipment (August 2022). The vendor's award history spans from February 2014 to March 2026, with the preponderance of awards issued via low-dollar purchase orders reflecting DLA's transactional procurement model rather than sustained contract vehicles. No GWACs, BPAs, or agency-wide IDIQs appear in the award history; all work flows through direct purchase-order competition.
