According to a declaration by Cameron Stanley, chief digital and artificial intelligence officer for the Department of War, Grok AI military use includes powering recent strikes during Operation Epic Fury in Iran. The Grok Gov Model reportedly enabled U.S. forces to "deploy over 2,000 munitions to 2,000 distinct targets within 96 hours," demonstrating what Stanley described as "greatly increased operational efficiency"

.NAACP Lawsuit Against xAI Targets Growing Pollution from Unpermitted Turbines
The air pollution lawsuit, filed by the NAACP in April 2026, alleges that xAI violated the Clean Air Act by operating natural gas turbines without proper permits at its Mississippi facility. The initial complaint identified 27 unpermitted gas turbines, but emails between xAI and state regulators obtained by the Southern Environmental Law Center show that number had grown to 57 turbines by mid-May—weeks after the lawsuit was filed

This expansion has resulted in dramatic increases in harmful emissions. According to the Southern Environmental Law Center, the site has experienced a 111 percent increase in nitrogen oxide emissions, an 83 percent increase in PM2.5 pollutants, and an 88 percent increase in formaldehyde emissions since April

.Legal Battle Tests Limits of Citizen Enforcement Against Corporate Polluters
The DOJ's argument extends beyond defending xAI to challenging the fundamental right of citizens to enforce environmental laws. Federal lawyers contend that "the Clean Air Act does not authorize citizen-enforcement actions that seek relief the governmental enforcers choose to forgo," suggesting that state determinations should shield companies from citizen lawsuits

The dispute occurs as SpaceX, which acquired xAI in February, plans massive expansion of its AI infrastructure. In SpaceX's IPO filing, the company disclosed plans to purchase $2.8 billion worth of gas turbines to power AI data centers over the next three years, with at least $2 billion earmarked specifically for "mobile gas turbines"

. This suggests the current legal battle may be a preview of larger conflicts between AI innovation demands and environmental protections.The case, pending in U.S. District Court for the Northern District of Mississippi, could establish whether national security claims can override environmental regulations and citizen enforcement rights. Watch for the court's decision on whether to grant the DOJ's dismissal motion or the NAACP's request for a preliminary injunction to halt turbine operations.
