In mid‑2024 a defense‑contractor‑deployed, fine‑tuned GPT‑4‑based intelligence assistant generated a hallucinated report claiming a Chinese merchant vessel in the Gulf of Oman carried clandestine nuclear‑weapon components. The output, produced via a retrieval‑augmented generation pipeline pulling classified SIGINT, open‑source news, and maritime data, was accepted as factual by analysts who recommended an immediate interdiction, moving a U.S. naval task force to Condition Alpha within 30 minutes. Human verification later disproved the claim, averting a boarding operation that would have incurred ~$1.2 million in operational costs and risked a US‑China military incident.
