US Military Used Anthropic AI Despite Trump Ban, Raising National Security Policy Concerns

The controversy over the use of artificial intelligence in U.S. national security operations has escalated after multiple reports indicated that Anthropic’s AI model Claude was deployed during U.S. military operations in the Middle East just hours after President Donald Trump issued a directive restricting federal agencies from using the company’s technology.

The Wall Street Journal and other outlets reported that the U.S. Central Command (CENTCOM) used Claude to support intelligence assessments, target identification, and battlefield simulations during coordinated airstrikes on Iranian targets — even as political leaders were distancing federal agencies from the company’s systems.

Background: Federal Ban and Supply Chain Risk Designation

Late last month, the Trump administration ordered all federal agencies to discontinue use of Anthropic’s AI tools, including Claude, citing national security concerns and labeling the company a supply chain risk after disagreements over how its models could be used in military and surveillance contexts.

Defense Secretary Pete Hegseth said that unrestricted access to AI technology was necessary for essential military applications — but Anthropic’s refusal to grant such access without safeguards prompted the supply chain risk label.

Six‑Month Phase‑Out Period

Although the federal directive formally prohibits further use of Anthropic technology, government guidance included a six‑month transition period for agencies to shift off Claude while maintaining operational capability. This timeline appears to explain the military’s continued use of Claude for the Iran operation.

Experts note that Claude had been deeply integrated into classified military networks — partly due to its earlier partnerships and Pentagon contracts — making an immediate cut‑off operationally complex.

Operational and Policy Implications

The deployment of Claude in an active combat environment has triggered fresh debate over the role of private AI companies in national defense. Critics argue that reliance on commercial systems highlights gaps in policy alignment between civilian regulatory action and military needs, while others warn that such AI use raises ethical, legal, and accountability challenges in warfare planning.

Some technology policy analysts say this episode highlights a broader issue: the rapid integration of AI into defense operations is outpacing the development of coherent, consistent policy frameworks.

Future of Military AI Strategy

In response to the rift with Anthropic, rival AI providers have reportedly moved to fill the gap. OpenAI has been named as a Pentagon partner for ongoing classified AI support, with its models slated to replace Claude over time as military systems transition.

Defense planners now face a pivotal question: how to balance national security imperatives, ethical limits on AI use in lethal operations, and the strategic risks of over‑dependence on private technology firms.

As this policy and technology dispute continues to unfold, it is likely to influence broader debates on AI governance, national security strategy, and the future role of privately developed AI systems in public sector missions.
