Supply chain risks are not unique to the DoD, but such risks take on greater urgency when considered in light of national security. For example, to keep aging weapon systems operational, we depend on a finite number of repair parts suppliers, some of which are precariously close to fiscal collapse. The proliferation of counterfeit items (particularly for microelectronics) increases the risk of mission delay or imperiled safety. Intellectual property vulnerabilities and lowered integrity of sensitive data and secure networks undermine the protections around our weapon system designs. Dependence on foreign entities for critical items and cyber disruptions to the manufacturing and transportation domains likewise jeopardize mission support and success.
