TheNational Defense Industrial Association (NDIA) is a tradeassociation for theUnited States government anddefense industrial base.[1][2] It is an501(c)(3) educational organization. Its headquarters are inArlington, Virginia. NDIA was established in 1919 as a result of the inability of the defense industry to scale up the war effort during World War I.[citation needed]
In 1917, Brigadier GeneralBenedict Crowell[3] was called to active duty and served on the General Munitions Board. As a board member, he established a relationship with the steel industry and was almost immediately appointed AssistantSecretary of War and Director of Munitions. As Director of Munitions, Crowell was a significant catalyst in improving[citation needed] the country's capability to produce arms and ammunition. However, he recognized the nation's need for an association that fostered cooperation between civilian industry and government in support of industrial preparedness. He founded the Army Ordnance Association (AOA) in 1919 and served as president for its first 25 years. Over the ensuing decades, AOA became the American Defense Preparedness Association (ADPA), which then merged with the 1944 National Security Industrial Association (NSIA) in 1997, creating NDIA.
In July 2024, NDIA signed a letter to members of both theHouse Committee on Armed Services and theSenate Committee on Armed Services opposing Section 828 of S. 4628, theNational Defense Authorization Act for Fiscal Year 2025, entitled "Requirement for Contractors to Provide Reasonable Access to Repair Materials".[4] The proposed Section 828 raised concerns for NDIA that include "no carve-outs or limitations to protect sensitive trade secret information" and impacts on "the economics of a dealer distribution model by effectively eliminating dealer margins ... [impacting] ... small and medium-sized businesses",[4] amongst other issues.[5]
NDIA currently publishesNational Defense,Weekly Policy Digest,Weekly Defense Insider, andMonthly Defense Watch.

a trade group that represents 900 military contractors
The main military manufacturers' organization, National Defense Industrial Association, has 9000 corporate affiliates and 36000 individual members with no foreign membership. The association maintains close coordination with the DOD functioning through thirty-four committees, each with direct access to and a working relationship with the military.
