CNN's sources claim the US nearly attacked a Chinese ship it believed was carrying nuclear weapon components. A false, partially AI-generated intelligence report nearly prompted the US military to attack a Chinese ship in the Middle East, CNN reports. The incident "almost started a war," according to a source cited in the report, and highlights the risks of incorporating AI into the sensitive work of the US Department of Defense.

Engadget has asked the Department of Defense to comment on CNN's reporting. The assessment was put together by a special operations command analyst who asked an AI chatbot about the Chinese ship's manifest. According to CNN, the chatbot combined "open-source intelligence with secret signals intelligence" to conclude that the ship contained the "components of a nuclear weapons program" — a claim that nearly led the military to apprehend the ship until officials found out it was AI-generated.

CNN wasn't able to find out what the ship was actually carrying or what AI tool the analyst used. In January, Secretary of Defense Pete Hegseth published a memo directing the DoD to become "AI-first." That didn't work out with Anthropic, who refused to let the military use its models for autonomous weapons, and was briefly banned. SpaceXAI reportedly struck a deal to let the military use Grok in February, and NVIDIA, Microsoft and Amazon entered a partnership in May.
