Pentagon Confirms Using Elon Musk's Grok AI to Deploy Missiles Against Iran

The U.S. Pentagon has officially confirmed that it used a specialized version of Elon Musk's Grok artificial intelligence chatbot to support military strikes against Iran. Cameron Stanley, the Pentagon's chief digital and artificial intelligence officer, made the disclosure in sworn testimony filed in a Mississippi court case on June 15, 2026. Stanley stated that Grok enabled U.S. forces to deploy over 2,000 munitions to 2,000 distinct targets within 96 hours during Operation Epic Fury. The testimony was presented as part of the Department of Justice's legal defense against a lawsuit filed by the NAACP, which alleges that xAI's data centers violate environmental regulations by operating gas turbines without proper permits in predominantly Black neighborhoods.

The Pentagon's reliance on Grok represents a significant shift in military AI strategy. Stanley testified that Grok is one of only four AI models currently capable of supporting national security applications and one of three equipped to support mission-critical operations in highly classified environments. The Pentagon specifically uses a product called Grok Gov Model, a suite designed for federal agencies with capabilities not found in publicly available versions of the chatbot. The Department of Justice argued in its legal brief that the xAI data center is essential to national security, stating that the lawsuit "threatens American national, economic, and energy security by seeking to shut off the power supply for artificial intelligence innovation that supports the Department of War's military operations."

The shift to Grok came after the Pentagon terminated its contracts with Anthropic in February 2026, following the company's refusal to allow its Claude AI tool to be used for fully automated strikes or mass surveillance of Americans. The government then pursued partnerships with competing AI developers, including Google, OpenAI, and xAI. The transition has not been seamless—military officials acknowledged in March 2026 that Claude was still being used for operations in Iran during the transition period. Elon Musk, a close ally of President Trump, folded xAI into SpaceX in February 2026, a move that preceded SpaceX's historic initial public offering on June 12, 2026.

The disclosure has intensified scrutiny of AI's role in military operations, particularly following civilian casualties from U.S.-led strikes. Military investigators believe American forces were responsible for a January 2026 strike on a girls' school in Minab, Iran, that killed at least 175 people, making it the deadliest incident for civilians since operations began in February 2026. Analysts have suggested that AI-driven targeting combined with human error—including outdated target maps—may have contributed to the civilian deaths. The Pentagon uses the National Geospatial-Intelligence Agency's Maven Smart System, which employs AI to identify potential targets, though officials note the system does not automatically create targets but rather supports human decision-making.

The Pentagon's use of Grok has prompted legislative responses from Democratic lawmakers concerned about insufficient safeguards. Senator Kirsten Gillibrand is preparing legislation to restrict military AI use, ensuring that human commanders retain control of life-and-death decisions and banning AI entirely for nuclear weapons, civilian surveillance, and autonomous weapons systems. "Right now, the Pentagon is moving toward deploying incredibly powerful AI technology without commonsense guardrails in place, which could have catastrophic consequences that make all of us less safe," Gillibrand stated. Meanwhile, the Pentagon continues to face legal challenges from multiple directions, including an ongoing dispute with Anthropic over the company's designation as a "supply-chain risk to national security."

Stanley's testimony emphasized the critical nature of the data infrastructure supporting these AI systems. He stated that xAI's Mississippi data center and others are positioned to provide essential surge capacity in the event of armed conflict or national security emergencies. The Pentagon argues that data centers powering government AI products constitute a long-term strategic tool vital to maintaining technological superiority over adversaries. The outcome of the NAACP's environmental lawsuit against xAI could have significant implications not only for the company's operations but also for the Pentagon's continued access to the AI capabilities it has come to rely upon for military operations.
