The DEMAND Act of 2026 requires the Department of Defense to factor in expected foreign military sales when planning its industrial base strategy and production decisions. Specifically, the Secretary of Defense must consider projected foreign military sales demand when conducting industrial base assessments, planning munitions production, planning support for major weapons systems, and deciding whether to increase production rates or expand manufacturing capacity. The bill aims to help the defense industry expand its production capacity, stabilize critical suppliers, and encourage private investment in key production lines by giving manufacturers better visibility into expected sales to foreign allies. The legislation applies to all ongoing and future foreign military sales and affects defense contractors, munitions manufacturers, and military suppliers across the industrial base. There is no specified funding amount or implementation deadline in the text provided.
