The Defense supply chain is under new pressure. Not only is COVID-19 contributing to ongoing logistical issues and program delays, it is severely stressing the commercial aerospace supply chain, a source of strength for the whole industry since the end of the Cold War. Meanwhile, new cybersecurity and supply chain integrity requirements are taking hold while the industry faces incremental political and defense budget risk.
