U.S. faces pressure to build weapons without China's rare-earth magnets

What This is

• Rare-earth metals are needed to make powerful permanent magnets used in missiles, jets, and other defense systems, but China dominates key processing steps.
• China’s export controls and trade pressure have tightened access and raised fears of supply shocks for defense and high-tech manufacturing.
• A White House order is pushing defense contractors to avoid China-based sources for certain “covered” materials, increasing demand for domestic or allied supply.
• Some industry executives and analysts warn U.S. mining and processing capacity may not be ready by a 2027 deadline to end reliance on Chinese critical minerals.
• Projects outside the U.S. are expanding supply too, including new mines and refineries in Australia and other regions, and partnerships with processors in Europe and Asia.
• Researchers say U.S. coal ash could be a large potential source of rare-earth materials, though extraction is still a developing process.

Why This Matters

• Weapons supply chains are only as secure as their least available materials, so shortages can limit production and repairs.
• Export controls show how one country’s grip on processing can become a bargaining tool in wider disputes.
• Building new mines, refineries, and magnet plants reshapes industrial policy by shifting government money toward domestic production and allied sourcing.
• More recycling and waste-based extraction could reduce pollution risks while lowering dependence on new mining.
