Heilind Mil-Aero LLC

Heilind Mil-Aero LLC (doing business as Interstate Connecting Components), a for-profit limited liability company headquartered in Lumberton, New Jersey, operates as a division of Heilind Electronics, Inc. and supplies electrical and fiber optic interconnect components to the Department of Defense and federal government as a prime contractor on 88% of recent awards, with the remainder as a subcontractor to major defense primes. The vendor competes predominantly in full-and-open, non-set-aside procurements and has not pursued 8(a), HUBZone, SDVOSB, or other small-business designations.

Heilind Mil-Aero's capability footprint centers on standardized and custom electrical connector components, backshells, cable assemblies, plugs, receptacles, protective covers, cable clamps, and fiber optic interconnect accessories—products aligned with NAICS 334417 (Electronic Connector Manufacturing) and PSC 59-P (Electrical/Electronic Equipment Components). Representative work includes a $132.1 thousand Naval Supply Systems Command purchase order (awarded January 2025) for F110 cable 833 with completion targeted for August 2025, a $147.4 thousand NAVSUP award (November 2024) for F110 cable 822, a $72.9 thousand Army Communications Electronics Command purchase order (June 2025) for 11 electrical connectors per NAVAIR drawing specification, a $58.0 thousand Naval Sea Systems Command contract (September 2024) for inboard electronic component kits, and recurring Defense Logistics Agency Land and Maritime orders ranging from hundreds to tens of thousands of dollars for plugs, backshells, connectors, fiber optic contacts, cable clamps, and adapters to support military equipment readiness and maintenance programs.

Customer concentration is extreme and monolithic. The Defense Logistics Agency Land and Maritime dominates the portfolio with 2,471 awards (88% of all awards) valued at $16.4 million in combined potential value, anchoring 93% of the vendor's total potential-value footprint when paired with the Bureau of Prisons facility (38 awards, $3.2 million). The Department of the Navy (Naval Sea Systems Command, Naval Supply Systems Command, Naval Air Warfare Center, and Naval Information Warfare Systems Command collectively) accounts for 369 awards and $2.9 million combined potential value. DLA Aviation adds 155 awards for $861 thousand. This concentration reflects the vendor's role as a standing supplier of standardized interconnect components across military logistics, not a diversified prime across civilian and defense agencies.

The vendor holds single-award indefinite delivery contracts (IDCs) with DLA Land and Maritime, each with $250,000 ceiling values and one-year performance periods, which gate nearly all of its prime award activity. A representative IDC awarded November 12, 2024, procures electrical connector plugs (NSN 5935011114533) with a $250,000 ceiling, estimated four task orders annually, and a guaranteed minimum of 41 units per year. Prior IDCs (May 2022 through May 2023) for electrical contacts and cable clamps similarly established the vehicle framework. Work is performed in Lumberton, New Jersey, with delivery distributed across domestic and overseas DLA depot locations. Top parent vehicles in recent activity include Indefinite Delivery Contract FA863819D0001 (40 task orders), N6523618D8014 (38 task orders), FA862520D3000 (12 task orders), and W58RGZ24D0065 (10 task orders), signaling participation in other government-wide or agency-specific vehicle structures beyond DLA single-awards, though the source does not detail vehicle issuing agencies or customer agencies for those vehicles.

Award activity has been volatile. The vendor recorded 340 awards in 2022, declined to 112 in 2023, rebounded to 276 in 2024, moderated to 199 in 2025, and shows only 13 awards year-to-date in 2026 (as of late July, a partial-year snapshot). Combined potential value across all awards stands at $25.1 million against $41.8 million in obligated dollars (167% of potential value), indicating that invoiced delivery on prior-year awards has exceeded initial ceiling projections or that the source's potential-value field reflects remaining ceiling rather than original contract values. The vendor's first recorded federal award dates to June 2009, and the most recent prime award closed April 2026, reflecting persistent activity across a 17-year window.

As a subcontractor, Heilind Mil-Aero supplies electrical connectors, plugs, backshells, fiber optic connectors, cable assemblies, adapters, and terminal boards to major defense primes including Northrop Grumman Systems Corporation (large aircraft infrared countermeasures programs, satellite communications, space missions), The Boeing Company (Space Launch System non-production, PBL material support), General Dynamics Mission Systems and General Dynamics (cable assemblies, electronic component integration), Raytheon Company (RF coaxial connectors), Lockheed Martin (implied in award summaries but no explicit recent sub-award listed), BAE Systems Technology Solutions (connector and backshell engineering labor), Science Applications International Corporation (terminal boards, connector and adapter kits, mobile command vehicle production support, communications system rack integration), Huntington Ingalls (CVN 75 refueling overhaul), Sikorsky Aircraft (CH-53K helicopters, Combat Rescue Helicopter airframe parts), Serco (radio frequency distribution and control, ship hardware installation), and others. Sub-award volume is modest—409 of 3,395 total awards (12%)—and concentrated in 2025 and 2026, suggesting either expanded prime-contractor relationships or enhanced data capture during the most recent two fiscal years.

Corporate structure identifies Heilind Electronics, Inc. (a Subchapter S corporation and for-profit entity headquartered in Wilmington, Massachusetts) as the parent company. The parent operates multiple divisions, with Interstate Connecting Components as a dedicated federal-government supplier division. Award summaries reference the vendor's "over 35 years of industry experience" supplying aerospace and defense interconnect solutions, positioning it as an established distributor within the Heilind corporate portfolio rather than a recent entrant.

The vendor competes across full-and-open federal procurements with no set-aside claims and does not appear in SBA 8(a), HUBZone, SDVOSB, WOSB, or EDWOSB designations. A small number of awards from the Bureau of Prisons facility (United States Penitentiary Marion) carry partial small-business set-aside language, but these do not reflect a strategic set-aside posture; the vendor competes for these opportunities alongside unrestricted commercial and government suppliers. Pricing is firm fixed price across the footprint, consistent with the standardized, commodity-component nature of electrical connectors and the DLA's procurement model for logistics spares.
