The United States military is severely short on high-end and artillery munitions at a crucial and strategic moment. As the calendar turns to 2024, Ukraine, using bombs and bullets from the United States, continues its slog of a war with Russia with no foreseeable end. Simultaneously, the U.S. continues sending artillery rounds to Israel amidst the Israel Defense Forces (IDF) assault on Hamas in Gaza. In the Indo-Pacific, American tensions with China remain high as Taiwan prepares for a general election with fears of Chinese interference and Chinese leader Xi Jinping promises the reunification of Taiwan with mainland China. In DC, alarm bells ring regarding the dearth of rounds required for these three distinct kinds of conflict. Central to this issue is an American paucity of rare earth minerals indispensable in producing these bombs, shells, and rockets. To address this shortage and ensure the long-term viability of ammo for high-end conflict, the U.S. must invest in and maintain innovative systems for processing and refinement of rare earth minerals.
An Empty Cupboard: A Paucity of Rare Earth Elements
Rare earth minerals – a set of 17 metallic elements – are the essential materials of bombs, bullets, rockets, and missiles. They are critical in manufacturing powerful magnets used in precision-guided munitions. Some rare earth elements possess temperature stability necessary for some high-tech bombs exposed to intense heat during launch toward target, such as the Javelin missiles so crucial to allowing Ukrainian forces to fend off Russian tanks. Rare earths are in the fuzes of the 155mm artillery shells used in enormous volumes by both the Armed Forces of Ukraine and the IDF. Many air-to-air missiles needed in a fight with China, including the AIM-9X Sidewinder missile, require these materials. Rare earths are used to build actuators for many surface-to-ground rockets.
The rare earth minerals are not particularly rare – these materials are bountiful in the earth’s crust. It is rather the production and refinement capability for the use of these materials – turning these elements into usable material – that is scarce within the U.S. The chemical properties of these materials are nearly identical from one another, making it difficult and costly to separate and refine each one for industrial use. The process also incurs environmental hazards that require expensive cleanup, often making large-scale production economically infeasible.
