Rare Earths in Defense and National Security

Rare earth elements (REEs) are a group of 17 chemically similar metals that play a critical role in modern technology. Although they are called “rare”, these elements are fairly abundant in the Earth’s crust, but they seldom occur in high concentrations that are economically practical to mine. This makes extraction and processing complex and expensive.

This group consists of 15 lanthanide elements including neodymium, dysprosium, and lanthanum, as well as the elements scandium and yttrium. These elements possess unique magnetic, luminescent, and electrochemical properties that are crucial for high-tech manufacturing and innovation.

Rare earth elements underpin many everyday technologies. Smartphones rely on rare earths for screens, speakers, and vibration motors. Electric vehicles depend on rare earth magnets to enhance motor efficiency and power. Wind energy systems rely on neodymium magnets for electricity production, while military systems use rare earths in radar, guidance systems, and communications equipment.

One reason rare earths are so valuable is their contribution to improved energy efficiency. Devices that use rare earth components often require less energy, generate less heat, and perform more reliably. As a result, they are critical to renewable energy development and sustainability goals.

China presently controls much of the global rare earth supply chain, representing a large share of worldwide production and refining. This dominance has triggered geopolitical and economic concerns, as interruptions could affect industries across the globe. Many countries are now seeking to diversify supply chains by investing in local mining operations and international partnerships.

Rare earth extraction also raises environmental issues. The extraction process can generate hazardous waste and radioactive byproducts if environmental safeguards are inadequate. As demand increases, both regulators and industry leaders are pushing for cleaner mining and recycling methods.
