The Pentagon has disclosed that Elon Musk's artificial intelligence platform Grok played a significant role in supporting military operations during a recent U.S. campaign against Iran, a revelation that is intensifying debate in Washington over the growing use of AI in national security and combat planning.
The disclosure emerged in a legal filing submitted by senior Defense Department officials as part of a separate court battle involving xAI, Musk's artificial intelligence company. Within the filing, Pentagon officials described Grok as one of a limited number of advanced AI systems capable of supporting sensitive national security missions.
According to Cameron Stanley, the Pentagon's chief digital and artificial intelligence officer, Grok helped support operations involving more than "2,000 munitions at 2,000 distinct targets within 96 hours." The filing did not specify the precise nature of the system's involvement in target selection, operational planning, or intelligence analysis.
Stanley wrote that Grok is among only four AI models "currently capable of supporting national security applications" and one of a small group of systems "equipped to support mission-critical operations" within classified environments.
The acknowledgment marks one of the clearest public indications yet that advanced commercial AI models are being integrated into real-world military campaigns. Defense officials have increasingly emphasized artificial intelligence as a force multiplier capable of processing vast amounts of intelligence and operational data faster than traditional systems.
The disclosure comes as scrutiny grows over civilian casualties linked to military operations in Iran. Human rights advocates and independent analysts have questioned whether AI-assisted targeting systems are receiving sufficient human oversight, particularly after reports that U.S. investigators were examining an attack in Minab that allegedly resulted in significant civilian deaths.
Defense officials have maintained that military AI platforms do not independently authorize strikes. Instead, systems operating under the Pentagon's broader Project Maven framework are designed to analyze intelligence, identify patterns, and highlight potential targets for review by human operators.
The legal filing also highlighted the Pentagon's dependence on computing infrastructure operated by xAI. Stanley argued that facilities supporting Grok are essential to maintaining military readiness and technological superiority, describing AI-powered infrastructure as a "long-term strategic tool vital to maintaining our technological advantage against adversaries."
The Justice Department echoed those concerns in court filings, arguing that restrictions affecting the development or deployment of Grok could hamper critical national security operations. Government lawyers said continued access to advanced AI systems is increasingly viewed as a strategic necessity.
The Pentagon's comments were made in connection with litigation brought by the NAACP against xAI. The lawsuit alleges that the company's data center operations violate environmental regulations by operating gas-powered turbines without required permits. Federal officials are seeking dismissal of the case, arguing that the facilities serve broader national security interests.
The disclosure has also fueled a legislative debate on Capitol Hill. Several lawmakers are pushing for new safeguards governing military AI applications, arguing that decisions involving lethal force should remain under direct human control.
Sen. Kirsten Gillibrand has become one of the leading voices calling for restrictions. "The most critical decisions affecting our national security and the lives of our service members must always be made by human beings, not unaccountable machines," she said in a statement.
Gillibrand also warned that "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."
