The US reportedly used Anthropic’s AI for its attack on Iran, just after banning it

In a lengthy post on Truth Social on February 27, President Trump ordered all federal agencies to “immediately cease all use of Anthropic’s technology” following strong disagreements between the Department of Defense and the AI company. A few hours later, the US conducted a major air attack on Iran with the help of Anthropic’s AI tools, according to a report from The Wall Street Journal.

The president noted in his post that there would be a “six-month phase-out period for agencies like the Department of War who are using Anthropic’s products,” so federal agencies are still expected to eventually move away from using Claude or other Anthropic tech. It’s also not the first time that the US used Anthropic’s AI for a major military operation, as the WSJ previously reported that Claude was used in the capture of the now-removed Venezuelan president Nicolás Maduro.

Moving forward, the Department of Defense may begin transitioning towards other AI options, especially after reaching deals with both xAI and OpenAI to use their models within the federal agency’s network. However, the WSJ reported that it would take months to replace Anthropic’s Claude with other AI models.
