The U.S. defense production faces significant delays due to the fragility of Tier-2 and Tier-3 suppliers, who provide essential components for major weapons programs. A 2021 explosion in Louisiana halted the only domestic black powder producer, exacerbating stockpile shortages.

Financial struggles of these smaller manufacturers, including limited capital and reliance on a few contracts, hinder their ability to meet demand. The Department of Defense has lost over 40% of small business suppliers, increasing dependence on single-source vendors.

Proposed increases in defense spending must reach these lower tiers sustainably to alleviate delays. Enhanced visibility into sub-tier dependencies and targeted government support, such as multi-year contracts, are needed to strengthen the industrial base and improve production timelines.
