About the company
Lake Shore Systems, Inc., doing business as Lake Shore Systems, is a Wisconsin-based precision components manufacturer that operates as a prime contractor on full-and-open federal procurements for the Department of Defense and Defense Logistics Agency, with no set-aside designation across its footprint. The company is a child entity of Oldenburg Group Incorporated, a for-profit manufacturer headquartered in Kingsford, Michigan.
Lake Shore Systems manufactures and supplies specialized mechanical components, hydraulic systems, and maritime equipment for naval vessel maintenance, repair, and construction. Its concrete capability portfolio centers on bushings, sleeves, bearings, gaskets, washers, seals, rollers, drums, winches, crane parts, hydraulic hoses and motors, stern ramp systems, and communication and positioning guide equipment. Representative recent awards include a $749,934 firm fixed-price purchase order from Defense Logistics Agency Aviation on September 5, 2025, for bushings and sleeves (NSN 5365015722033) with delivery by October 30, 2026; a $1.378 million purchase order from Military Sealift Command on September 28, 2023, for 5-ton crane parts supporting the USS Emory S. Land (AS-39); and a $768,893 sole-source purchase order from Military Sealift Command on January 31, 2022, for original equipment manufacturer supervision of stern ramp maintenance aboard the USNS City of Bismarck (T-EPF 9).
Customer concentration is heavily weighted toward the Department of the Navy and Defense Logistics Agency. By award count, the top five customers—Defense Logistics Agency Land and Maritime (551 awards, $6.2 million combined potential value), Defense Logistics Agency Troop Support Hardware (309 awards, $1 million), Defense Logistics Agency Aviation (286 awards, $4.6 million), Military Sealift Command (151 awards, $14 million), and Naval Supply Systems Command (150 awards, $6.7 million)—account for 83% of all awards. However, by potential value, Naval Sea Systems Command dominates with 128 awards valued at $72.56 billion combined potential value, vastly exceeding all other customers and reflecting the company's role as a supplier of components for major naval vessel construction and modernization programs. This divergence signals that Naval Sea Systems Command places fewer but substantially larger orders, while DLA and other Navy commands place numerous smaller-dollar purchase orders.
Lake Shore Systems holds two indefinite delivery contracts. The primary vehicle is a single-award IDC with Defense Logistics Agency Aviation (ceiling $696,348) for communication and positioning guide equipment over a five-year period; a $48,840 firm fixed-price delivery order was issued against this contract on October 14, 2021. The company also appears on SeaPort-e with two task orders valued at $72.55 billion combined potential value, predominantly anchored by the Naval Sea Systems Command relationship. Additional parent vehicles include DLA Land and Maritime and Army Materiel Command IDCs carrying smaller order values.
Activity has contracted sharply in recent years. The company received 22 awards in 2022, declining to 6 in 2023, 2 in 2024, 6 in 2025, and 1 award year-to-date in 2026 (as of March 3, 2026). Three awards reach ultimate completion within the next twenty-four months, carrying combined potential value of $1.3 million and representing modest recompete exposure. Lake Shore Systems operates exclusively as a prime contractor (100% of awards); no subcontract footprint is present in the source data. The company's historical awards span from October 2006 through March 2026, accumulating 1,740 total federal awards with combined potential value of $72.62 billion, though only $57.3 million has been obligated to date.
