However, the global defense supply chain is complex. Certain specialized components, raw materials, or sub-assemblies may be sourced from various countries, including China, based on cost, availability, or unique expertise. The U.S. government maintains strict controls on critical defense technologies to mitigate supply-chain risks.
In summary, while final assembly and core production occur in the United States, it is possible that some minor parts originate from Chinese manufacturers.
