US Pushes Massive Drone Expansion Amid Critical Dependence on Chinese Rare Earths

However, behind this ambitious military expansion lies a major strategic vulnerability: the United States remains heavily dependent on China for the rare-earth magnets essential to drone production.

According to industry reports, nearly 98 percent of the world’s high-performance rare-earth magnets are manufactured in China. These magnets, particularly neodymium-iron-boron magnets, are critical components in drone motors, sensors, guidance systems and advanced military electronics.

The US government has allocated $13.6 billion for drone programs in its 2026 defense budget, underscoring how central drones and artificial intelligence have become to Washington’s future war strategy. President Donald Trump signed an executive order in June titled “Unleashing American Drone Dominance,” aimed at boosting both military and commercial drone production. A month later, Defense Secretary Pete Hegseth directed the Pentagon to accelerate drone procurement efforts.

Yet experts warn that the expansion may be constrained by supply-chain realities.

The Pentagon estimates that around 80,000 components used across nearly 1,900 US weapons systems rely on rare-earth materials sourced from China. Heavy rare-earth elements such as dysprosium and terbium are particularly important because they allow magnets to maintain performance under extreme heat and pressure inside jet engines and drone motors.

The growing importance of drones has been reinforced by the war in Ukraine, where unmanned systems have transformed the battlefield. Reports suggest Ukraine produced more than 1.2 million drones in 2024 alone, with most relying on magnets linked to Chinese supply chains.

To reduce dependence on Beijing, companies such as REE Alloys and MP Materials are attempting to build domestic supply chains for rare-earth processing and magnet production. Another company, Vulcan, is developing what is expected to become the largest rare-earth magnet factory outside China.

The Pentagon has also invested directly in the sector, including purchasing $400 million worth of shares in MP Materials, making the US government the company’s largest shareholder.

Still, significant obstacles remain. Mining permits in the United States can take between seven and ten years to obtain, while a fully operational mine may require nearly three decades to develop — among the slowest timelines globally.

Analysts say the central question now is whether the United States can build an independent rare-earth supply chain quickly enough to support its expanding drone ambitions, or whether its military future will continue to depend on Chinese materials.
