Lake Shore Systems, Inc.

Lake Shore Systems, Inc., operating as parent to subsidiary Custom Alloy, LLC, is a for-profit precision mechanical and hydraulic component manufacturer headquartered in Kingsford, Michigan, that supplies fasteners, mechanical parts, hydraulic assemblies, and specialized maritime equipment to the Department of Defense as a prime contractor (93% of awards) competing predominantly in full-and-open procurements with no SBA set-aside participation. The company has over 160 years of federal contracting experience and manufactures components at facilities in Kingsford and Iron River, Michigan, and Norfolk, Virginia.

Lake Shore Systems' customer base concentrates heavily on Navy and Defense Logistics Agency logistics operations. By award count, the Defense Logistics Agency Land and Maritime leads with 1,529 awards ($22.9 million combined potential value), followed by DLA Aviation (918 awards, $10 million) and DLA Troop Support Hardware (552 awards, $1.4 million); the three DLA units collectively represent 72% of awards. By dollar value, the Department of the Navy dominates: Naval Sea Systems Command holds 450 awards valued at $65.7 million, Military Sealift Command 165 awards at $32.6 million, and Naval Supply Systems Command 140 awards at $25.4 million. Together, Navy commands account for 755 prime awards and approximately 64% of the combined potential value. The two rankings diverge meaningfully — DLA places many small purchase orders while Navy commands anchor the largest dollars — reflecting Lake Shore's embedded role as a routine parts supplier to DLA's distribution network and a specialized supplier to Navy ship maintenance and construction programs.

Lake Shore Systems' capability footprint centers on the manufacture and supply of mechanical components across maritime, aviation, and defense logistics: fasteners (hexagon head cap screws, lead balance screws), precision machined parts (shafts, gears, pulleys, sheaves, manifolds), hydraulic assemblies and manifolds, hoisting equipment (drum winches, chain hoists, davits), bearings, seals and gaskets, electrical components, and refurbishment and repair services for ship systems. Representative prime work includes a $2.44 million firm fixed-price purchase order from Military Sealift Command for 5-ton crane parts supporting the USS Emory S. Land (May 2025); a $1.99 million Naval Supply Systems Command definitive contract for filter units (October 2025); a $1.99 million definitive contract for pump units, also from Naval Supply Systems Command (August 2025); and a $3.76 million Army Contracting Command definitive contract for an interconnect guillotine (April 2025). Much of Lake Shore's volume consists of smaller purchase orders for individual components — fasteners, seals, manifolds, control assemblies, shims — flowing through DLA's indefinite delivery vehicles, each valued in the $3,000 to $100,000 range. Engineering and technical services work appears sporadically; a $557,209.63 cost-plus-fixed-fee delivery order from Naval Sea Systems Command for hull and deck machinery support (May 2026) and a $353,007 delivery order for LRHS system reliability modifications and environmental qualification testing (February 2026) exemplify the technical services Lake Shore performs alongside component supply.

Lake Shore Systems holds established positions on Navy and DLA indefinite delivery contracts. The source identifies at least five named IDV vehicles: an N3220517D4700 IDC carrying 62 task orders valued at $10.6 million (the largest named vehicle), an N0002419G2319 Basic Ordering Agreement with 21 task orders, an N0002418D4325 IDC with 11 task orders, an N6449818D4008 IDC with 10 task orders ($6.3 million), and an HSCG8513DP30H22 IDC with 9 task orders ($586 thousand). Two single-award DLA Land and Maritime indefinite delivery contracts, each valued at $250,000, for drive unit angle configurations and turnbuckle bodies, appear repeatedly in award summaries as parent vehicles for delivery orders. The breadth of IDV positions reflects Lake Shore's status as a routine, full-and-open supplier across Navy and DLA procurement channels.

Activity has declined year over year — 590 awards in 2022 dropping to 35 in 2026 (year-to-date through early August). This trajectory reflects the source data's temporal scope rather than a recompete cliff; only 15 awards with ultimate completion dates within the next twenty-four months carry combined potential value of $1.8 million, a modest recompete exposure. The vendor's dollar-obligated share ($182.4 million) exceeds its potential-value total ($176.5 million) by 103%, indicating most orders have flowed to invoice and closure.

Lake Shore Systems operates as a subcontractor to major Navy and defense primes on ship construction, maintenance, and modernization work. Named prime contractors include Huntington Ingalls Incorporated (multiple LCS-class ship alteration and LHA-8 engineering sub-awards), BAE Systems Maritime Solutions (USS Kansas City and USS Paul Hamilton maintenance sub-awards), Epsilon Systems Solutions (USS Charleston and LCS repair delivery orders), Vigor Marine LLC (USS Gabrielle Giffords platform lift and USNS Matthew Perry overhaul sub-awards), Marinette Marine Corporation (FFG(X) engineering services), Metro Machine Corp. (USS Oak Hill docking availability), and East Coast Repair & Fabrication, LLC (USS Winston S. Churchill and USS Iwo Jima repair work). Sub-award descriptions indicate Lake Shore operates under its Trident Maritime Systems and Trident Maritime Solutions business identities when subcontracting, suggesting those names carry subsidiary or operating-unit status. Subcontract work ranges from platform lift system testing and slewing arm davit overhaul on Littoral Combat Ships to steelwork and engineering support on carrier construction. Sub-awards represent only 7% of total award count (287 sub-awards against 3,757 prime awards), but the named relationships confirm Lake Shore as an embedded supplier within the Navy's principal shipbuilders.

By NAICS, Lake Shore's work clusters in ship building and repairing (378 awards), fastener manufacturing (bolt, nut, screw, rivet, and washer manufacturing; 334 awards), bearing manufacturing (328 awards), hardware manufacturing (312 awards), and gasket and sealing device manufacturing (304 awards). By PSC code, the top categories are packing and gasket materials (388 awards), miscellaneous power transmission equipment (251 awards), bearings (222 awards), nails and machine keys (201 awards), and gears and pulleys (188 awards). This taxonomy confirms Lake Shore's positioning as a precision component and parts supplier rather than a systems integrator or program management contractor.

Lake Shore Systems competes in full-and-open federal procurements with no reliance on SBA set-asides. The source documents no 8(a), HUBZone, SDVOSB, WOSB, or other preferential designations; all awards carry "No Set-Aside Used" language, indicating the company wins contracts on the basis of capability and price in open competition. This posture is consistent with Lake Shore's scale, established infrastructure, and specialty in precision manufacturing — a market position where full-and-open competition is the norm and where the vendor's long operational history and technical reputation drive award decisions.
