The story at a glance

A WSJ live update reports that U.S. Central Command used Anthropic's Claude AI tool during air attacks on Iran, just hours after President Trump directed federal agencies to end use of the company's AI due to security concerns. The strikes are part of a broader U.S.-Israeli operation against Iran that began around the same time. Centcom declined to comment on specific systems in its ongoing operations.[[1]](https://www.wsj.com/livecoverage/iran-strikes-2026/card/u-s-strikes-in-middle-east-use-anthropic-hours-after-trump-ban-ozNO0iClZpfpL7K7ElJ2)

Key points

Trump on Friday ordered agencies to halt work with Anthropic and the Defense Department labeled it a supply chain security risk.[[1]](https://www.wsj.com/livecoverage/iran-strikes-2026/card/u-s-strikes-in-middle-east-use-anthropic-hours-after-trump-ban-ozNO0iClZpfpL7K7ElJ2)

The article appears in WSJ's live coverage of Iran strikes starting February 28, 2026, amid escalating U.S.-Iran hostilities.[[1]](https://www.wsj.com/livecoverage/iran-strikes-2026/card/u-s-strikes-in-middle-east-use-anthropic-hours-after-trump-ban-ozNO0iClZpfpL7K7ElJ2)

Details and context

The piece is a short card in WSJ's real-time blog on U.S. and Israeli strikes against Iran, which Trump described as targeting "imminent threats" to prevent nuclear weapon development. These operations, dubbed Operation Epic Fury by the Pentagon, hit sites including Tehran without prior congressional approval, drawing Republican praise and Democratic criticism.[[3]](https://www.wsj.com/livecoverage/iran-strikes-2026/card/what-to-know-about-the-u-s-iran-conflict-9wNSVzBfP9LdnYCzy6KT)

Trump's ban stems from disputes over Anthropic's AI guardrails, with the administration favoring alternatives like OpenAI. Yet military commands had already integrated Claude deeply, showing how operational realities can outpace policy changes in active conflicts.[[4]](https://www.wsj.com/news/author/amrith-ramkumar)

Key quotes

None directly quoted in available excerpts; reporting relies on anonymous sources familiar with the matter and official non-comments from Centcom.[[1]](https://www.wsj.com/livecoverage/iran-strikes-2026/card/u-s-strikes-in-middle-east-use-anthropic-hours-after-trump-ban-ozNO0iClZpfpL7K7ElJ2)

Why it matters

AI integration in warfare raises questions about policy enforcement amid national security priorities during U.S.-Iran escalation. Military users face immediate reliance on banned tools, potentially complicating Trump's directives on tech vendors and supply chain risks. Watch for Pentagon responses, legal challenges from Anthropic, or shifts in AI use as the conflict evolves.[[4]](https://www.wsj.com/news/author/amrith-ramkumar)
