Rare Earth Supplies in U.S. to Meet Defense Needs, Pentagon Says

Domestic rare earth supplies will meet the U.S. defense industry’s needs by 2013 for the materials that go into military motors and electronics, according to a Pentagon report sent to Congress.

China, the world’s largest producer of rare earth materials, accounting for at least 90 percent of the global supply, has tried to restrict supplies. The 17 materials include elements such as neodymium, samarium and dysprosium that also go into commercial products, including hybrid batteries, mobile phones and computer hard drives.
