US Military’s Use of Anthropic’s Claude AI in Iran Strikes Sparks Controversy
In a recent turn of events, the U.S. Department of Defense (DoD) utilized Anthropic’s Claude AI during Operation Epic Fury, a coordinated offensive with Israel targeting Iranian facilities on February 28, 2026. This deployment occurred mere hours after President Donald Trump designated Anthropic as a national security supply chain risk and mandated all federal agencies to cease using its AI systems.
Operation Epic Fury and Claude’s Role
On February 28, 2026, U.S. and Israeli forces initiated Operation Epic Fury, aiming at critical Iranian government installations, including nuclear sites and strategic military infrastructure. Reports from reputable sources such as The Wall Street Journal, Axios, and Reuters indicate that the U.S. Central Command employed Anthropic’s Claude AI for intelligence assessments, target identification, and battlefield simulations during the operation.
The timing of this deployment is particularly noteworthy, as it closely followed the Trump administration’s formal declaration of Anthropic as a supply-chain risk—a designation intended to immediately restrict the company’s access to defense contracts. Defense officials acknowledged the challenges of rapidly disengaging from Claude, given its deep integration into certain classified U.S. government networks.
Escalating Tensions Between Anthropic and the Pentagon
The discord between Anthropic and the Pentagon intensified after a January 2026 operation that led to the capture of Venezuelan President Nicolás Maduro, during which Claude was also reportedly utilized. This revelation heightened tensions between the AI developer and U.S. defense leadership.
Central to the dispute is Anthropic’s acceptable use policy, which explicitly prohibits the use of Claude for:
– Autonomous weapons systems
– Mass surveillance of U.S. citizens
Pentagon officials have advocated for unrestricted use of the model, arguing that operational necessities should not be constrained by a contractor’s ethical policies.
On February 26, 2026, Anthropic CEO Dario Amodei publicly reaffirmed the company’s commitment to these restrictions, leading to increased pressure from the DoD. The following day, Secretary of Defense Peter Hegseth announced Anthropic’s designation as a supply-chain risk but allowed a six-month period for a seamless transition, acknowledging the extensive integration of Claude into classified infrastructure.
OpenAI’s Agreement with the Department of War
Shortly after the Pentagon’s announcement, OpenAI CEO Sam Altman revealed that his company had reached an agreement with the Department of War to deploy its AI models within classified military networks. Altman emphasized the DoD’s deep respect for safety during negotiations and noted that the agreement includes terms barring the use of OpenAI models for domestic mass surveillance and autonomous weapons systems—conditions similar to those Anthropic had proposed.
Altman also announced that OpenAI would station dedicated safety engineers within the Pentagon to monitor model behavior and urged the Department of War to extend equivalent terms to all AI vendors operating in defense environments.
Anthropic’s Legal Challenge
In response to the supply-chain risk designation, Anthropic has vowed to challenge the decision in court, arguing that its ethical safeguards are fundamental safety commitments necessary before deploying AI systems in sensitive environments.
Implications and Future Considerations
The deployment of Claude AI during Operation Epic Fury, despite the presidential ban, underscores the complexities of integrating advanced AI technologies into military operations. It highlights the tension between operational imperatives and ethical considerations, as well as the challenges of rapidly disengaging from deeply embedded technologies.
As AI continues to play a pivotal role in defense strategies, establishing clear policies and agreements that balance national security interests with ethical standards will be crucial. The ongoing developments between the DoD, Anthropic, and other AI vendors will likely shape the future landscape of AI integration in military operations.
