Failure Shuts Down Squadron of Nuclear Missiles - Marc Ambinder - Politics - The Atlantic: "President Obama was briefed this morning on an engineering power failure at F.E. Warren Air Force Base in Wyoming that took 50 nuclear intercontinental ballistic missiles (ICBMs), one-ninth of the U.S. missile stockpile, temporarily offline on Saturday.
The base is a main locus of the United States' strategic nuclear forces. The 90th Missile Wing, headquartered there, controls 150 Minuteman III intercontinental ballistic nuclear missiles. They're on full-time alert and are housed in a variety of bunkers across several states."
