B.c. Systems Inc.

B.C. Systems Inc., doing business as BC Systems Inc., is a woman-owned and veteran-owned small business manufacturer based in Setauket-East Setauket, New York that designs and manufactures custom military power supplies, power controls, electromagnetic relays, voltage monitoring devices, sensors, and related electronic components as a prime contractor (94% of recent awards) to the Defense Logistics Agency and Department of the Navy. The company is a subsidiary of Advanced Manufacturing Company Of America, Inc., a self-certified small disadvantaged business. B.C. Systems competes predominantly under Total Small Business set-asides, with recurring awards across both set-aside and full-and-open designations.

The vendor's customer concentration is overwhelming and singular. The Defense Logistics Agency Land and Maritime accounts for 287 awards carrying $25.6 million in combined potential value, representing 86% of award count and dominating the dollar ranking as well. This deep dependency on a single customer division and purchasing pattern — steady, repetitive orders for the same qualified products list items — distinguishes B.C. Systems' business model from broader defense contractors. DLA Aviation, the next-largest customer, accounts for 41 awards valued at $4.5 million. The Department of the Navy's Naval Supply Systems Command (35 awards, $1 million potential value) and Naval Air Systems Command (19 awards, $440 thousand potential value) round out the top tier. Together, the top five customers cover 86% of the award count.

The vendor holds multiple single-award Indefinite Delivery Contracts with DLA Land and Maritime, typically valued at $250,000 each, that serve as standing vehicles for firm fixed-price delivery orders. The most recent IDC award, May 2025, carries a $250,000 ceiling for electromagnetic relays (NSN 5945010959395) running through May 2026. B.C. Systems issued roughly 7 delivery orders per year under these vehicles as of mid-2025. Representative prime work includes a $469,500 Total Small Business purchase order from DLA Land and Maritime for 60 electric power monitors (NSN 6110012467177) awarded April 2025, a $279,020.70 Total Small Business order from DLA Aviation for tachometer sensors (NSN 6680010279882) awarded April 2025, and a $343,380 Total Small Business purchase order from DLA Land and Maritime for 60 electronic power monitors awarded February 2026.

Activity volume has grown modestly over the past five years — from 21 awards in 2022 to a peak of 33 in 2024 — though 2025 and 2026 show a pullback to 23 and 9 awards respectively within the bounded source data window. Eleven awards (combined potential value $1.7 million) complete within the next twenty-four months, creating recompete exposure centered on the DLA's standing demand for electromagnetic relays and power monitoring components.

In its subcontractor role, B.C. Systems supplies power supplies, DC-DC converters, inspection drawings, and boost inductors to BAE Systems Information And Electronic Systems Integration Inc. for Common Missile Warning System production hardware across multiple foreign military sales programs (Poland, Greece, Austria, Germany, Korea, Egypt, Kuwait, Jordan); provides flow, pressure, and flight switch components to Raytheon under the Advanced Technology Support Program for radar and enhanced Coyote block upgrades; and supplies electra/hydra/mechanical components to The Boeing Company for MQ-25 and F-15EX programs. L3Harris Technologies also draws on B.C. Systems for aircraft parts and auxiliary equipment manufacturing under Big Safari. The subcontract work, while 6% of the award count, often carries higher individual values than the repetitive DLA prime orders, suggesting material revenue contribution despite the volumetric skew toward prime work.

Capability portfolio centers on electromagnet relays (NAICS 334614, PSC 30), electric power monitors and voltage monitoring devices (NAICS 334519, PSC 61), power supply units and DC-DC converters, sensors including tachometer sensors, hybrid relays, and related power distribution and control assemblies. The source cites manufacturing expertise spanning electromagnetic relays, power monitoring devices, custom power supply modules, and electronic assemblies supporting military vehicles, communications systems, and defense platforms. The combined potential value across all 529 awards is $34.3 million, though obligated dollars total $56.5 million — indicating prior-year carryover and completion of contracts awarded before the source data window began.
