About NDIA


The National Defense Industrial Association drives strategic dialogue in national security by identifying key issues and leveraging the knowledge and experience of its military, government, industry, and academic members to address them.

NDIA, comprised of its AffiliatesChaptersDivisions, and 1,780 corporate and 65,000 individual members, is a non-partisan, non-profit, educational association that has been designated by the IRS as a 501(c)3 nonprofit organization - not a lobby firm - and was founded to educate its constituencies on all aspects of national security.

NDIA formed from a merger between the American Defense Preparedness Association, previously known as the Army Ordnance Association, founded in 1919, and the National Security Industrial Association, founded in 1944. For 100 years, NDIA has provided a platform through which leaders in government, industry, and academia can collaborate and provide solutions to advance the national security and defense needs of the nation.

NDIA Chapters offer the opportunity for individual and business coordination with regional military commands and working levels of the federal government. They are important elements that help NDIA and its members understand defense and national security requirements and needs.

National Defense Magazine

NDIA's monthly journal, National Defense, provides information on the latest developments in technology, arms and weaponry, and other important business information tailored to issues of concern for industry and government.

Policy Issues

NDIA works to strengthen the government-industry partnership through dialogue, education, and interaction with Congress and Executive agencies. Through its Policy team, NDIA monitors, advances, and educates its members on legislative and regulatory activity of importance to the defense industrial base. NDIA is also part of several industry working groups and coalitions that meet periodically to coordinate the defense and government contracting communities' position on specific issues.
