US Defense Sector Faces Strategic Risk Over Chinese Rare Earth Dependency

The U.S. defense industry, which sees annual spending of approximately $900 billion, is grappling with a critical dependency on Chinese supply chains for rare earth magnets. These materials are essential for advanced military systems, including fighter jets, missiles, and naval destroyers. While the U.S. expects $10 trillion to flow through defense production over the next five years, China continues to dominate the industrial conversion of rare-earth oxides into magnet-grade metals. This strategic bottleneck exists because North America outsourced mid-stream processing decades ago, leaving even domestic ore reliant on Chinese facilities. Consequently, companies like Lockheed Martin and Raytheon face supply chain vulnerabilities, while domestic miners like MP Materials may see increased support as the U.S. seeks to decouple from Chinese dominance.
