Confirmed or suspected counterfeit parts in DOD's electronics supply chain

摘要

The Air Force and Navy use these oscillators in more than 4,000 systems, including the Joint Surveillance Target Attack Radar System (Joint STARS). Deficient receivers in Joint STARS could cause mission failure. An approved DOD supplier purchased the oscillators from a distributor that had used an unapproved source of supply, and the problem was detected when the part had a high failure rate during depot repair. After detection, the contractor removed parts from the depot parts bin but could not account for five parts. Officials reported that those five parts might never be found.
