Emil Michael, head of science and technology at the U.S. Department of Defense, revealed in a podcast that negotiations between the Pentagon and artificial intelligence company Anthropic ultimately collapsed, resulting in the department designating an American firm as a "supply chain risk" for the first time in its history, effectively blacklisting it. Michael stated that the Pentagon remains deeply concerned about the possibility of Anthropic cutting off access to its AI systems during critical military operations. The core conflict centers on operational autonomy. During discussions regarding missile defense systems, Anthropic CEO Dario Amodei suggested that the Pentagon could contact them by phone in exceptional circumstances. However, Michael countered that during pivotal moments such as missile launch sequences, military decisions cannot rely on human communication; instead, system autonomy must be guaranteed. Relations deteriorated further after Michael accused Amodei of lying and possessing a "God complex." The Pentagon contends that Anthropic's model strategy based on proprietary value judgments introduces policy biases that could compromise weapon designs or intelligence processing risks. Michael emphasized that the decision was neither punitive nor arbitrary but grounded in pragmatic national security considerations aimed at ensuring contractors like Lockheed Martin do not utilize models carrying uncontrollable biases. Currently, the U.S. military has accelerated efforts to deploy alternative solutions, specifically commending xAI and OpenAI for their rapid response to Department of Defense requirements in establishing new systems capable of operating within classified environments to replace Anthropic. Although Amodei claims there have been recent "constructive dialogues," Michael insists no ongoing negotiations exist. Meanwhile, Anthropic has announced plans to challenge this sanction through legal channels. While Boeing retains permission to continue using Anthropic services outside defense contexts, the aerospace manufacturer has been excluded from military-industrial applications involving these technologies.
