US Military Nearly Boarded a Chinese Ship After an AI Chatbot Hallucinated Nuclear Cargo

The US military nearly boarded a Chinese cargo ship in the Middle East after a chatbot invented a nuclear-weapons payload.

Four people familiar with the episode told CNN that a Special Operations Command analyst used an unnamed chatbot that misidentified cargo on a Chinese commercial ship as nuclear-weapons-program components. Officials caught the error before anyone went up the gangway. The account rests on anonymous sources. The Pentagon has not put a named chatbot on the record.

The episode happened in spring 2026, during the Iran war. CNN did not establish what the ship was actually carrying. The military prepared to intercept and board the vessel with air support. The boarding did not happen.

The chatbot fused open-source intelligence with secret signals intelligence in government holdings. The analyst then used AI a second time to package those findings into a standard intelligence report that military officials trusted.

Officials discovered the chatbot had inaccurately identified the material just before the planned operation. One source said the report was "entirely false" and "almost started a war." Preparing to intercept is not the same as launching an attack.

DoD rolled out an AI acceleration strategy in January. GenAI.mil was built on Gemini for Government, announced in December, with Grok for Government added later. The Pentagon told Congress in June that 1.5 million active DoD personnel have used military generative AI tools.

The same issued-device problem showed up when the US military disabled ad trackers on government phones and PCs.
