Rare earth elements are central to the United States’ military technology that operates across the air, land, sea, and space domains. Their strong magnetic and electronic characteristics enable compact, high-performance motors and actuators used in precision-guided munitions, missile control, and advanced aircraft such as the F-35 fighter jet.
In naval operations, rare earth magnets and alloys enhance radar, sonar, and propulsion systems aboard Virginia-class submarines and Arleigh Burke destroyers, providing the stealth and detection capability that defines modern warfare.
The US uses roughly 20 tonnes each year, a quantity small enough to fit on a single truck, but its strategic weight is immense. Gallium underpins radar, communication, and satellite systems across the Pentagon’s advanced platforms. Yet despite its importance, the country has no domestic production and relies entirely on imports.
