Northern Defense Industries, LLC

Northern Defense Industries, LLC, a for-profit limited liability company and small business manufacturer headquartered in Alexandria, Virginia, supplies specialized defense-related electronic components, radar system parts, cable assemblies, and technical support services to the federal government as a prime contractor (94% of recent awards), with a substantial recurring IDC and delivery-order footprint anchored by Coast Guard radar sustainment work.

The company operates as a full-and-open competitor without set-aside designations on most awards, though it holds two small business set-aside indefinite delivery contracts with the Defense Logistics Agency Aviation ($250,000 ceiling for cable assemblies) and prior awards from DLA and DoD Land and Maritime carrying total small business set-aside tags. Northern Defense Industries is a subsidiary of Hensoldt Inc. and has been registered in SAM since at least 2009. Recent activity shows sharp growth—one award in 2022 to 41 in 2024 and 40 in 2025—driven primarily by a $9 million Coast Guard IDC for AN/SPS-75 air search radar sustainment and maintenance through August 2029, which anchors the vendor's federal footprint. In May 2026, the Coast Guard awarded a follow-on single-award indefinite delivery contract with a $42.1 million ceiling, also through 2029, for supply parts and overhaul services for the same radar systems.

Customer concentration is extreme. The Department of Homeland Security US Coast Guard dominates the portfolio: 12 awards carrying $62.4 million combined potential value (86% of all dollars), driven by the two large IDCs and associated delivery orders. The top five customers by potential value account for 97% of total dollars. By award count (76% coverage), Defense Logistics Agency Aviation leads with 21 awards ($1.3 million potential value), followed by DLA Land and Maritime (17 awards, $550 thousand), DLA Troop Support Construction and Equipment (14 awards, $652 thousand), Naval Supply Systems Command (13 awards, $2 million), and the Coast Guard (12 awards, $62.4 million). The split reveals tension: DLA Aviation places many small purchase orders ($30–$70K range for cable assemblies, components, and consumables), while Coast Guard anchors most of the contract value through two large IDCs and associated sustainment delivery orders. Northern Defense Industries' capability set reflects this concentration: cable assemblies for radio systems, circuit card assemblies, RF/IF units, controllers, power supplies, antenna components, and repair/refurbishment services for AN/SPS-75 radar systems installed on Coast Guard National Security Cutters and at the Training Center Petaluma, California.

The vendor's NAICS footprint spans Current-Carrying Wiring Device Manufacturing (14 awards), Search, Detection, Navigation, Guidance, Aeronautical, and Nautical System and Instrument Manufacturing (11 awards), and Bare Printed Circuit Board Manufacturing (7 awards), with PSC concentration in Cable/Cord/Wire Assemblies—Communication Equipment (13 awards) and Electrical and Electronic Assemblies, Boards, Cards (12 awards). Place of performance is primarily Alexandria, Virginia, with subordinate work at Kearneysville, West Virginia, and various Coast Guard operational and training locations (Petaluma, Alameda, Baltimore, Charleston, Mayport, Honolulu).

As a prime, Northern Defense Industries operates its own delivery pipeline on most work. SCI-reported invoicing shows $277 thousand in FY2024 across 0.4 FTEs, with median government-paid rates at approximately $280/hr—reflecting labor-minimal, component-heavy delivery on purchase orders rather than labor-intensive services. Across SCI-reportable prime contracts, 19% of contractor hours were performed by subcontractors, suggesting Northern Defense Industries builds modest sub-teams for repair and refurbishment work but retains most manufacturing and procurement in house. The company subcontracts to Fairwinds Technologies LLC (control transmitter and circuit card assembly procurement as of late 2025), Lockheed Martin Corporation (LCS-25 facility support and labor), and Atlantic Diving Supply, Inc. (AN/SPS-80 MAMS kit supply in October 2024).

The recompete cliff in the next twenty-four months totals 13 awards worth $2.6 million combined potential value—modest relative to the Coast Guard IDC dominance, but the $42.1 million IDC awarded May 2026 represents significant new delivery-order volume beginning in base-year execution through 2029, and the $9 million predecessor IDC continues through 2029, together accounting for the vast majority of Northern Defense Industries' federal workload. The vendor's primary competitive moat is established, sole-source standing with the Coast Guard as the original-equipment-capable repair and sustainment source for AN/SPS-75 radar systems; secondary revenue streams come from component supply to Naval Supply Systems Command and DLA Aviation on full-and-open competition, with minimal visibility to growth outside Coast Guard and naval maintenance contracts.
