An Executive Order directing the federal government to lock down defense supply chains and prioritize domestic sourcing of critical materials was signed by President Donald J. Trump on July 20, 2026, according to the White House.
The order centers on materials and components needed to manufacture advanced military equipment. The White House said a core objective is eliminating uncertainty within U.S. military supply chains, which the administration framed as essential to maintaining dominance on the modern battlefield.
The directive covers cutting-edge equipment used by U.S. forces, with particular attention to the critical inputs required to produce that equipment domestically.
