U.S. military could be shut down by secret 'back door'..A missile failure could result from defective products from China ..

U.S. Department of Defense over recent months purchased 59,000 microchips to use in Navy equipment that control everything from missiles to transponders..But all of the chips turned out to be cheap knock-offs from China, and they ultimately were not installed, according to sources.

Besides being subject to failure, the chips also were designed with a "back door" which would have allowed the chip, and the device it controlled, to be shut down remotely at any time, sources report.Had the flaw not been detected, the chips could have shut down U.S. warships, aircraft, advanced weapons systems and encoded transponders that distinguish friendly aircraft from hostile attackers.

"It is clear from recent trends in the microelectronics industry that a significant migration of critical microelectronics manufacturing from the United States to other foreign countries has and will continue to occur. The rate of this technology migration is alarming because of the strategic significance this technology has on the U.S. economy and the ability of the United States to maintain a technological advantage in the Department of Defense (DoD), government, commercial and industrial sectors. Our greatest concern lies in microelectronics supplies for defense, national infrastructure and intelligence applications."
