The United States Department of Defense (Pentagon) requested that deliveries of F-35 jets to customers continue. This is related to the discovery of F-35 engine components made by Honeywell, where it turns out that there are cobalt and samarium alloy components from China. However, the alloy is magnetized in the United States.
He explained that there are two things about using components from China. “First, the impact on security, if any. And second, the impact on airworthiness or safety, if any,” said LaPlante.
This, he said, proves that the defense industry relies on components that sometimes the main defense contractors themselves do not know every detail of their component supply chain.
