About the company
Northern Defense Industries, LLC, a for-profit limited liability company based in Alexandria, Virginia, is a small-business manufacturer of defense-related electronic components, radar system parts, and cable assemblies that operates predominantly as a prime contractor (95% of recent awards) on full-and-open federal contracts without set-aside designations, with selective Total Small Business set-aside awards concentrated in Defense Logistics Agency and Department of Defense Land and Maritime procurement.
The vendor's customer concentration is heavily skewed toward the U.S. Coast Guard, which accounts for 18 awards worth $66.9 million in combined potential value—83% of the vendor's total federal contract portfolio. This concentration reflects Northern Defense Industries' established position as a specialized supplier for AN/SPS-75 air search radar system sustainment, repair, and component procurement for Coast Guard National Security Cutters and the Training Center in Petaluma, California. The vendor holds a $42.1 million Coast Guard indefinite delivery contract for AN/SPS-75 supply parts and repair services through May 2029, awarded May 7, 2026, and a $9 million Coast Guard indefinite delivery contract for sustainment and maintenance technical support through August 2029, awarded August 7, 2024. Secondary customers include Naval Supply Systems Command (19 awards, $5.3 million), Defense Logistics Agency Aviation (22 awards, $1.7 million), and Defense Logistics Agency Land and Maritime (17 awards, $431 thousand). Recent representative work includes a $1.4 million Coast Guard delivery order for AN/SPS-75 radar supply parts (August 27, 2026), a $509.3 thousand Naval Supply Systems Command purchase order for RF/IF units (January 28, 2025), and a $166.3 thousand Defense Logistics Agency Aviation purchase order for dry air units under a total small business set-aside (March 6, 2024).
Award activity has grown substantially, expanding from one award in 2022 to 41 in 2024 and 40 in 2025, with 19 awards in 2026 year-to-date. Twenty-one awards worth $10.7 million in combined potential value face ultimate completion within the next twenty-four months, presenting recompete exposure concentrated in Coast Guard AN/SPS-75 sustainment work and Naval Supply Systems Command component procurement. The vendor's contract portfolio spans electrical and electronic assemblies (15 awards), cable and cord assemblies (13 awards), and radar equipment (12 awards), reflecting a focused capability in specialized defense electronics manufacturing and repair rather than broad-based defense services.
SCI reporting shows $2.1 million invoiced in FY2025 across 2.1 FTEs on three prime service contracts, up from $277 thousand and 0.4 FTEs in FY2024, indicating modest growth in labor-intensive service delivery relative to a portfolio dominated by goods and component procurement. Government-paid hourly rates on SCI-reportable contracts average $279.94/hr across the vendor base. Across SCI-reportable prime contracts, subs account for an average 5% of contractor hours, and the vendor names one subcontractor in SCI records, indicating a predominantly self-performing delivery model. In its subcontractor role, Northern Defense Industries supports Lockheed Martin Corporation on Littoral Combat Ship support labor (June 23, 2024 and October 30, 2024), Fairwinds Technologies LLC on controller and circuit card assembly procurement (October 30, 2025 and November 14, 2025), and Atlantic Diving Supply on AN/SPS-80 maintenance, amphibious, and materials support kit procurement (October 2, 2024). The vendor holds a $250 thousand Defense Logistics Agency Aviation small-business-set-aside indefinite delivery contract for cable assemblies awarded June 24, 2024, and a defense supplier relationship with Hensoldt Inc., a for-profit subsidiary, which provides original equipment and authorized source components for AN/SPS-75 radar systems.
