US used Musk’s Grok AI to deploy 2,000 munitions during Iran war

What Happened

Cameron Stanley, the Pentagon’s Chief Digital and Artificial Intelligence Officer, disclosed in a written declaration to the United States District Court for the Northern District of Mississippi that US forces employed the Grok Gov Model—a derivative of xAI’s commercial AI—within the Maven Smart Systems (MSS) to strike over 2,000 targets in 96 hours during Operation Epic Fury, the joint US-Israel war on Iran. The declaration, part of the Trump administration’s intervention in a civil case where the NAACP is suing xAI for illegally operating methane gas turbines, did not specify exact dates but referenced the conflict that began on 28 February (year unspecified). Iran’s Foundation of Martyrs and Veterans claimed nearly 3,500 people have been killed by US-Israeli attacks since that date. Stanley asserted that the MSS workflows enabled the rapid deployment of 2,000 munitions and framed the partnership as vital to national security, warning that shutting down the Colossus 2 data center—powered by the contested turbines—would impair the Pentagon’s ability to ‘keep pace with adversaries’.

Key Actors

Why It Matters

This marks the first official admission that the US used an AI model developed by Elon Musk’s xAI in an active warzone, directly linking AI-enabled targeting to kinetic strikes that resulted in thousands of casualties. The disclosure emerges from a clash between environmental civil litigation and national security claims, highlighting how critical AI infrastructure—like the Colossus 2 supercomputer—is now framed by the Pentagon as a strategic military asset comparable to munitions production. The case raises urgent questions about transparency, accountability, and the ethical implications of integrating black-box AI into lethal operations, especially when operational details such as strike dates and civilian harm assessments remain obscured.

Watch For

The federal judge’s ruling on the NAACP’s motion and the Department of Justice’s dismissal plea, which could set a precedent for shielding military-linked AI infrastructure from environmental laws. Any further court disclosures or congressional inquiries into Operation Epic Fury’s timeline, targeting protocols, and casualty figures. The Pentagon’s ongoing dependence on xAI models and potential fallout for Musk’s defense contracts if the data center is forced to reduce operations.
