Rare Earth Elements in National Defense

facilities in China, how may this move affect the domestic supply of rare earth minerals for the production of U.S. defense weapon systems?

  • Given that DOD’s assessment of future supply and demand was based on previous estimates using 2010 data, could there be new concern for a possible rare earth material supply shortage or vulnerability that could affect national security?

  • Are there substitutes for rare earth materials that are economic, efficient, and available?

  • Does dependence on foreign sources alone for rare earths pose a national security

threat?

Congress may encourage DOD to develop a collaborative, long-term strategy designed to identify any material weaknesses and vulnerabilities associated with rare earths and to protect long-term U.S. national security interests.
