Elon Musk ’s Grok AI was reportedly used by the U.S. military during its war against Iran in February and March, according to a sworn statement from Pentagon artificial intelligence chief Cameron Stanley. Stanley said the chatbot supported the launch of more than 2,000 munitions against 2,000 separate targets within 96 hours. The statement marks the first reported official confirmation that Grok was involved in the conflict. Earlier reporting had connected Anthropic’s Claude AI to U.S. targeting operations, but military officials declined to confirm whether Claude played a role in the February 28 bombing of the Shajareh Tayyebeh girls’ school. What Did Grok Reportedly Do? According to The Independent, the school strike killed at least 175 people, including more than 100 children. A separate attack on Iran’s Azadi Sport Complex followed on March 5, while the broader conflict reportedly killed thousands of Iranians and damaged civilian sites. Stanley made the Grok disclosure while defending Musk in a Clean Air lawsuit involving xAI. Stanley described Grok as one of four AI models capable of supporting national security applications and one of three products cleared for mission critical operations with high confidentiality requirements. Stanley also argued that keeping Grok operational without outside interference was “a matter of paramount national security.” The statement does not publicly explain how Grok contributed to individual targeting decisions, leaving the scope of Musk’s chatbot’s military role unclear even as the Pentagon frames its continued availability as strategically important.
