Heilind Mil-Aero, LLC

Heilind Mil-Aero, LLC, doing business as Trek Connect, manufactures specialized electrical connectors, cable assemblies, and related components for defense and aerospace applications as a prime contractor (79% of recent awards) and subcontractor to major defense primes. A for-profit limited liability company and subsidiary of Heilind Electronics, Inc. (a Subchapter S corporation based in Wilmington, Massachusetts), Heilind Mil-Aero operates from Lumberton, New Jersey, and competes full-and-open without set-aside designations across the vast majority of its federal footprint, though it holds one small-business set-aside award. The company has been registered in SAM since 2013.

Heilind Mil-Aero's federal work centers on purchase orders for high-precision electrical interconnect products — connectors (plug connectors, dummy connectors, connector assemblies), cable and wire assemblies (power cables, special-purpose cables, fiber-optic cables), microphones, and maintenance kits. Representative prime awards include a $44,169 firm fixed-price purchase order from the Defense Logistics Agency's Land and Maritime division in January 2026 for 26 units of connector assemblies (NSN 5935016323948) with delivery to DLA Distribution San Joaquin, a $137,872 firm fixed-price purchase order from the Office of Naval Research in September 2025 for cables, a $130,213 firm fixed-price purchase order from Naval Sea Systems Command in February 2022 for composite box assemblies, and a $99,566 purchase order from the Department of Justice Bureau of Prisons in July 2022 for cable and wire products. Most awards are small individual purchase orders; the source reflects combined potential value of $2.2 million across 160 prime awards, with combined dollars obligated of $5.3 million (142% surplus suggests re-obligations and task-order activity under parent IDIQs).

The vendor's customer concentration is heavily skewed toward the Department of Defense logistics and naval commands. The top five customer agencies account for 92% of awards: the Defense Logistics Agency's Land and Maritime division (82 awards, $507 thousand combined potential value), the Defense Logistics Agency's Aviation division (46 awards, $325 thousand), Naval Sea Systems Command (39 awards, $823 thousand — the highest single-customer dollar concentration), the Department of the Army Acquisition Support Center PEO Missiles and Space (12 awards, unspecified value), and the Department of Justice Bureau of Prisons United States Penitentiary Marion (8 awards, $326 thousand). The split between award count and potential value reveals that Naval Sea Systems Command places fewer awards but anchors higher-dollar work, while DLA Land and Maritime distributes its procurement across numerous smaller orders.

Activity shows volatility: 20 awards in 2022, 9 in 2023, 44 in 2024, 21 in 2025, and 3 year-to-date in 2026. The spike in 2024 reflects increased purchase-order volume rather than vehicle consolidation; the source does not indicate a recompete cliff. Parent contract vehicles are limited and task-order light: Indefinite Delivery Contract W56KGY-22-D-0001 (a Lockheed Martin / Navy contract vehicle) carries 12 task orders; Advanced Technology Support Program IV carries 2 task orders; and three other vehicles carry one task order each. The modest IDV footprint suggests Heilind Mil-Aero operates primarily as a direct procurement vendor for DLA, Naval Sea Systems Command, and other agencies rather than through large government-wide vehicles.

Heilind Mil-Aero's subcontractor portfolio reveals deep integration with major defense primes. The vendor supplies cable assemblies, connectors, and related components to Lockheed Martin Corporation (the dominant sub relationship, with dozens of funding modifications and task orders on Advanced Technology Support Program and other contracts, including fiber-optic cables, power cables, and special-purpose electrical assemblies for naval radar and combat systems), General Dynamics Mission Systems, Inc. (software engineering services and goods), Sierra Space Corp (tracking-layer electronic components), Fluor Marine Propulsion, LLC (Naval Nuclear Laboratory support—cabinet and whip assemblies), Science Applications International Corporation (cables, connectors, and crimps), Bell Boeing Joint Project Office (coax adapter sets), Atlantic Diving Supply, Inc. (data bus terminator assemblies), and Electric Boat Corporation (naval systems components). Subcontract work spans combat systems integration, submarine propulsion support, radar modernization, and aircraft systems, with some work supporting Ukraine assistance programs.

Award portfolio concentration by product category reflects the vendor's core capability: connectors and electrical products dominate. The top NAICS codes are Electronic Connector Manufacturing (44 awards), followed by Search, Detection, Navigation, Guidance, Aeronautical, and Nautical System and Instrument Manufacturing (31 awards), and Other Building Material Dealers (56 awards, likely a classification artifact for component procurement). Top PSC codes align identically: Connectors, Electrical (73 awards), Cable, Cord, and Wire Assemblies for Communication Equipment (40 awards), and Headsets, Handsets, Microphones and Speakers (11 awards). No GSA Schedule, GWAC, or government-wide BPA presence appears in the source; the vendor's posture is transactional, award-by-award, with significant leverage from defense prime subcontracting relationships rather than institutional vehicle position.
