The Pentagon announced a $1 billion direct-to-supplier investment to strengthen the U.S. solid rocket motor supply chain. The investment partners with L3Harris’ Missile Solutions, which is separating from the parent company as part of the contract. The investment will support the expansion of production for a node that is critical to national security and the munitions industrial base.
“We are fundamentally shifting our approach to securing our munitions supply chain,” said Under Secretary of War for Acquisition and Sustainment Michael Duffey. “By investing directly in suppliers we are building the resilient industrial base needed for the Arsenal of Freedom.”
He added, “This direct-to-supplier model is a crucial step toward replenishing stockpiles, rebuilding our military, and reestablishing deterrence by ensuring the availability of critical components.”
