U.S. Marine Corps Researchers Expose Rare Earth Magnet Bottleneck in America's Million-Drone Ambition

Highlights

• Three USMC officers at the Naval Postgraduate School analyzed component-level supply chain vulnerabilities in small drones like the Skydio X10 and Red Cat Edge 130.
• One million quadcopters could require four million motors dependent on Chinese-controlled neodymium-iron-boron (NdFeB) permanent magnets.
• The thesis cites Rare Earth Exchanges for its analysis of China's dominance in rare earth magnet manufacturing.
• Researchers identify an industrial investment paradox: manufacturers need purchase commitments before scaling, while buyers demand proven capacity first.
• Malaysia's role as a drone assembly hub does not confirm the origin of magnets, motors, or semiconductors used in those systems.
