About the company
NDI Engineering Company, doing business as NDI, is a for-profit naval architecture and marine engineering services provider headquartered in Thorofare, New Jersey, that operates as a prime contractor (96% of recent awards) on full-and-open federal contracts with no small business set-aside designations, though it qualifies as a small business and holds several Total Small Business set-aside task orders under larger IDIQs.
NDI's federal footprint centers on naval engineering, hull-mechanical-electrical (HM&E) systems design and technical support, submarine communication and electromagnetic systems, land-based test-facility design, and logistics support services, complemented by Defense Logistics Agency component supply (aircraft thermocouples, hose assemblies, synchronous drive belts, electrical resolvers, and piping assemblies). The company draws on a $496.1 million Hull, Mechanical and Electrical Machinery and Systems Services IDIQ with Naval Sea Systems Command (NAVSEA) running through July 2029, a $42.9 million submarine communication and electromagnetic systems support contract also with NAVSEA through August 2027, and a $47.5 million land-based engineering test-site design contract through September 2027. Recent representative awards include a $32.3 million Seaport Next Generation delivery order (October 2025) for lifecycle management of cargo and weapons handling and aircraft launch/recovery systems; a $15 million DMSMS and integrated logistics program-support delivery order from Naval Sea Systems Command (March 2026); a $4.9 million Naval Air Warfare Center delivery order for labor services (August 2025); and a $6.9 million Total Small Business set-aside order for AN/BRR-6C TCBX design, fabrication, testing, and implementation for Columbia Class submarines (March 2025).
Naval Sea Systems Command dominates customer concentration: 219 awards valued at $11.62 billion represent the bulk of NDI's pipeline, while Naval Air Systems Command Naval Air Warfare Center places 79 awards worth $263.3 million. Defense Logistics Agency Land and Maritime accounts for 89 awards, predominantly low-value purchase orders under $100,000 for component supply. The top-five customers cover 88% of award count. NDI works under two primary parent vehicles: Seaport Next Generation (Seaport-NXG), a Navy-administered GWAC, which carries 82–72 task orders across NAVSEA and NAVAIR, and the HM&E Machinery and Systems Services IDIQ (64–49 task orders depending on scope). Place of performance splits between Thorofare/West Deptford, New Jersey and Philadelphia, Pennsylvania.
Activity has held steady over the past five years (25–30 awards annually), with 15 awards (combined potential value $37.7 million) maturing in the next twenty-four months and facing recompete. SCI-reportable invoiced revenue totaled $13.3 million across FY2022–FY2024, with FY2023 peak at $9.4 million across 54.3 FTEs and FY2024 dropping to $3.3 FTEs—a compression reflecting transition between contract vehicles. Government-paid hourly rates on prime contracts range from $66/hr (10th percentile) to $163.38/hr (90th percentile), with median around $77.82/hr. NDI self-performs roughly 91% of labor on its SCI-reportable prime contracts, with occasional subcontractor engagement across five named subs.
As a subcontractor, NDI partners with Northrop Grumman Systems Corporation (Arc Upgrade III electrical component manufacturing and human-resources services), W R Systems Ltd. (prototype and engineering development model labor), Noblis MSD LLC (engineering and logistics support for boiler and steam systems), Gibbs & Cox Inc. (electrical switchboard alteration and installation for USS Blue Ridge), Life Cycle Engineering Inc. (DDG 1000 machinery control systems support), and QED Systems Inc. and Sayres and Associates LLC on Navy program management and logistics tasks. Subcontract volume has grown incrementally, with nine sub awards in 2024–2025 against a 953-prime portfolio, indicating NDI competes and delivers predominantly as a prime, not as a feeder sub.
