The U.S. Army plans to fund construction of rare earths processing facilities, part of an urgent push by Washington to secure domestic supply of the minerals used to make military weapons and electronics, according to a government document seen by Reuters. The move would mark the first financial investment by the U.S. military into commercial-scale rare earths production since World War Two's Manhattan Project built the first atomic bomb. It comes after President Donald Trump earlier this year ordered the military to update its supply chain for the niche materials, warning that reliance on other nations for the strategic minerals could hamper U.S. defenses.
