National Defense Industrial Association

National Defense Industrial Association, a tax-exempt non-profit organization based in Arlington, Virginia, operates as a prime contractor organizing and managing defense-industry conferences, exhibitions, and training events for federal customers — notably the Department of the Navy, Department of Defense agencies, and the Department of Homeland Security — exclusively under full-and-open, non-set-aside procurements.

NDIA's federal footprint centers on event planning and logistics services. Recent work includes a $28,500 purchase order from the Naval Air Warfare Center (awarded November 25, 2025) for exhibit booth space and meeting facilities at the Interservice/Industry Training, Simulation, and Education Conference (I/ITSEC) 2025 in Sand Lake, Florida; a $51,198 Naval Air Systems Command order (November 2023) for booth space at I/ITSEC 2023; and a $19,350 Naval Sea Systems Command purchase order (June 2023) for conference registrations at NDIA's annual conference. The vendor also holds single-award BPAs with the Defense Logistics Agency Aviation for planning and logistics services supporting the DLA Supplier Conference (DLA Supply Chain Alliance Conference 2027–2031, awarded June 2026, and the prior 2025–2026 iteration, both with zero-dollar ceilings as IDIQ vehicles). Work spans exhibit space procurement, venue accommodations, catering, printed materials, conference registrations, and coordination services across the defense industrial base.

Customer concentration skews heavily toward the Navy. The top five customers by award count — Department of the Navy Naval Sea Systems Command (42 awards, $287 thousand potential value), Naval Air Systems Command's Naval Air Warfare Center (33 awards, $876 thousand potential value), Department of the Army (22 awards), Army Materiel Command's Research Development and Engineering Command (21 awards, $116 thousand potential value), and Army Contracting Command Aberdeen Proving Ground (11 awards, $7 thousand potential value) — account for 45% of total awards. By potential value, Naval Air Systems Command's Naval Air Warfare Center leads at $876 thousand across 33 awards; the Department of Homeland Security (Office of Procurement Operations and US Coast Guard combined) follows with $847 thousand across eleven awards. The Navy dominates both rankings and represents the plurality of NDIA's federal customer base.

NDIA's award portfolio spans 286 total federal contracts as prime (100% prime, zero sub awards), with 51 distinct customer agencies served. Award volume has declined sharply — two awards in 2022, three in 2023, three in 2024, one in 2025, and one in 2026 — signaling either a shift in how customers procure conference services or completion of multi-year standing agreements. The combined potential value of $3.7 million masks an historically obligated base of $29.5 million across the full portfolio, reflecting a legacy of regular conference purchasing that has contracted in recent years. The top service categories are Professional Organizations (132 awards), Convention and Trade Show Organizers (47 awards), and Lessors of Nonresidential Buildings (27 awards); the top PSCs are Education/Training—Tuition/Registration/Membership Fees (40 awards) and Lease-Rent of Conference Space & Facilities (55 awards combined). NDIA operates as the sole incumbent provider for several standing conferences, particularly I/ITSEC and the DLA Supply Chain Alliance Conference, indicating entrenched positioning in defense-sector event administration.
