Pentagon realizes that it no longer controls who manufactures the components that go into its increasingly complex systems. A single plane like the DOD's next generation F-35 Joint Strike Fighter, can contain an "insane number" of chips, says one semiconductor expert familiar with that aircraft's design. Estimates from other sources put the total at several hundred to more than a thousand. And tracing a part back to its source is not always straightforward. The dwindling of domestic chip and electronics manufacturing in the United States, combined with the phenomenal growth of suppliers in countries like China, has only deepened the U.S. military's concern.
In December, the Defense Advanced Research Projects Agency (DARPA), the Pentagon's R&D wing, released details about a three-year initiative it calls the Trust in Integrated Circuits program. The findings from the program could give the military-and defense contractors who make sensitive microelectronics like the weapons systems for the F-35-a guaranteed method of determining whether their chips have been compromised. In January, the Trust program started its prequalifying rounds by sending to three contractors four identical versions of a chip that contained unspecified malicious circuitry. The teams have until the end of this month to ferret out as many of the devious insertions as they can.
