A new national security report has just been released: The 2015 National Defense Stockpile Requirements Report documents projected shortfalls in various metals, minerals and materials required for the U.S. defense industrial base and, in this day of dual-use technologies, the “essential civilian economy.”
In all, the new report details shortfalls that, in classified crises scenarios, would affect 30 metals and minerals – about 1/3 of the naturally occurring elements in the Periodic Table. Many of the metals and minerals used in U.S. defense applications aren’t exactly household names. There’s bismuth, used in defense thermo-electrics to capture ‘waste heat” and channel it back into weapons systems power sources. Weapons builders need iridium – used in aircraft engines, satellites and rocket propulsion– as an alternative to America’s present reliance on Russian supply.
In the case of tellurium, used in thermal imaging and navigation systems, present tellurium production, already sharply limited, will soon drop to zero, increasing U.S. dependency on China, Russia and Japan. Rhenium and molybdenum are essential to high-performance alloys used in jet turbines and other defense systems – as is more cobalt, used in jet engine super-alloys and samarium-cobalt permanent magnets. As the Pentagon study notes:
