Lake Shore Systems, Inc.

Lake Shore Systems, Inc. operates as a prime contractor supplying precision mechanical and hydraulic components, specialized maritime equipment, and repair services to the Department of Defense, competing predominantly in full-and-open federal procurements with no set-aside posture. The company is a for-profit manufacturer headquartered in Kingsford, Michigan, with a subsidiary, Trident Maritime Systems—Heavy Equipment Group (formerly Aircraft Appliances and Equipment Ltd.), and maintains over 160 years of federal contracting experience serving naval and defense logistics agencies through both direct component manufacturing and vessel maintenance work.

Lake Shore Systems' concrete capability set centers on precision component manufacturing and maritime equipment support. Recent representative work includes a $1.99 million Naval Supply Systems Command definitive contract awarded October 16, 2025, for filter unit fluid components with delivery of six units by September 3, 2026; a $752.6 million Military Sealift Command purchase order dated January 6, 2025, for traveling crane repair parts for USS Frank Cable and USS Land with completion by July 24, 2025; and a $2.44 million Military Sealift Command award issued May 5, 2025, for 5-ton crane parts supporting USS Emory S. Land with completion by December 31, 2025. The company also delivers smaller-dollar orders across Defense Logistics Agency for hydraulic manifolds, solenoid valves, drive units, turnbuckle bodies, sheave assemblies, brake components, and fasteners—all firm fixed-price procurements in the sub-$500 thousand range, issued against standing indefinite delivery contracts. Lake Shore Systems also performs sole-source component repairs and refurbishment work, including a $524.9 thousand Naval Supply Systems Command repair contract for strainer sediment recovery and a $239.8 thousand Military Sealift Command stern ramp winch refurbishment award for USS Brunswick.

Customer concentration is heavily weighted to Navy and Defense Logistics Agency customers. The Department of the Navy Naval Sea Systems Command leads on potential value with 445 awards worth $65.1 million combined, followed by Military Sealift Command (162 awards, $32.3 million), and Naval Supply Systems Command (136 awards, $25.5 million). Defense Logistics Agency Land and Maritime dominates by award count with 1,526 orders worth $22.8 million, while DLA Aviation carries 918 awards at $10 million combined potential value. Together, these five customer organizations account for 89% of combined potential value across the portfolio. The concentration reflects Lake Shore Systems' embedded position as a supplier to Navy vessel maintenance, repair, and logistics operations across multiple commands and DLA's distributed component ordering across its regional distribution centers.

Lake Shore Systems sits on two standing indefinite delivery contracts with Defense Logistics Agency Land and Maritime—each valued at $250 thousand, awarded May 5, 2023, and June 21, 2023, respectively—for drive unit angle configurations and turnbuckle bodies. Both IDCs have expired or are near expiration (completion dates May 4, 2024, and June 20, 2024), though the source shows ongoing delivery orders issued well into 2025 and 2026, suggesting the contracts remain active or have been extended. The largest parent vehicle by task order volume is Navy Indefinite Delivery Contract N3220517D4700 (62 task orders, $10.6 million combined potential value), followed by a Basic Ordering Agreement N0002419G2319 (20 task orders). This vehicle position is modest relative to the total portfolio, indicating Lake Shore Systems relies more on spot procurements and smaller standing agreements than on large government-wide vehicles.

Activity trajectory shows significant decline from historical peak. Awards per year dropped from 590 in 2022 to 284 in 2023, then stabilized at approximately 200-300 per year through 2024-2025, with only 21 awards recorded for 2026 year-to-date (as of mid-July 2026). Combined potential value across the entire portfolio stands at $175.7 million against $181.7 million obligated (103% of potential value), indicating the source captures obligated performance across completed and active periods. The recompete cliff presents minimal near-term exposure: only 18 awards with completion dates in the next twenty-four months carry combined potential value of $4.8 million—a small fraction of annual activity historically.

As a subcontractor, Lake Shore Systems (operating under the Trident Maritime Systems trade name on many sub-awards) performs ship alteration work and crane system repairs under major naval shipyards and systems integrators. Named prime relationships include Huntington Ingalls Incorporated (multiple ship alteration work and LHA/LPD engineering rebuys), BAE Systems Maritime Solutions San Diego Inc. (USS Kansas City LCS-22 and USS Paul Hamilton DDG-60 repair work), Vigor Marine LLC (USS Gabrielle Giffords LCS-10 lift platform system operability testing and USNS Matthew Perry overhaul support), Epsilon Systems Solutions Inc. (LCS-class repair delivery orders), Metro Machine Corp. (USS Oak Hill DSRA work), East Coast Repair & Fabrication LLC (USS Iwo Jima and USS Winston S. Churchill shipboard work), and Marinette Marine Corporation (FFG(X) frigate engineering services). The subcontract work is concentrated in Littoral Combat Ship (LCS) and amphibious vessel maintenance and repair, where Lake Shore Systems provides labor, materials, supervision, and technical representation for crane, winch, davit, and platform systems.

Lake Shore Systems competes in full-and-open federal procurements with no SBA set-aside participation and no designated minority, women-owned, HUBZone, SDVOSB, or other preference status. The vendor's posture across prime and sub work reflects reliance on technical incumbency (sole-source awards for OEM components and repair services where technical data rights are held or reverse engineering is uneconomical) and established prime contractor relationships, rather than on set-aside carve-outs. The award footprint is concentrated in mechanical and hydraulic component manufacturing (NAICS categories including ship building and repairing, bolt and fastener manufacturing, bearing manufacturing, gasket and sealing device manufacturing, and gear and transmission equipment) with secondary focus on ship repair and maintenance services. This capability and customer concentration—anchored to Navy vessels and DLA logistics support—positions Lake Shore Systems as a deep specialist in defense maritime supply chain support rather than a broad-spectrum federal supplier.
