The U.S. government has said that Elon Musk’s AI tool Grok was used in strikes against Iran, according to multiple reports citing U.S. government material. The claims appear in the context of legal and procurement issues involving AI systems used by U.S. entities.

One report says the U.S. Department of Justice references the Iran strikes when defending an xAI data centre that is being challenged by an environmental lawsuit. Another account links the discussion to broader U.S. policy on AI use in military operations and surveillance. It reports that, at the end of February, the U.S. government terminated contracts with Anthropic after the company would not agree to allow its tools to be used for fully automated strikes or for mass surveillance of Americans.

A separate report says the U.S. acknowledges that its shift toward AI in military settings is still underway, and that other AI systems, including Claude, were also being used in the war-related context in March.
