The US government wants you to know that Elon Musk’s AI chatbot is apparently so vital to national defense that it justifies running dozens of unpermitted gas turbines in a Mississippi neighborhood.

The Department of Justice has intervened in a lawsuit filed by the NAACP against xAI and its subsidiary MZX Tech, siding with the AI company’s continued operation of natural gas turbines that power its Colossus 2 data center in Southaven, Mississippi. The turbines lack Clean Air Act permits and pollution controls. The DOJ’s argument: the Pentagon needs Grok running on classified networks, and pulling the plug would compromise national security.

57 turbines, zero permits

The NAACP filed its lawsuit in April 2026, initially citing 27 unpermitted gas turbines at the facility. That number has since ballooned to 57.

To put that in perspective, 57 gas turbines generating hundreds of megawatts of power is roughly equivalent to a conventional power plant. Except conventional power plants go through years of environmental review before firing up. xAI apparently skipped that step.

The DOJ signaled its intent to intervene in May 2026, filing documents that frame the case not as an environmental dispute but as a question of AI leadership and national security. Pentagon officials have confirmed that Grok supports classified military operations, including recent operations related to Iran.

The government isn’t arguing that xAI shouldn’t eventually get permits. It’s arguing that forcing compliance right now, which could mean shutting down the turbines, would disrupt military AI capabilities at a moment when the US is actively using them in theater.

When national security meets the Clean Air Act

The NAACP’s lawsuit frames this as an environmental justice issue. Communities near large industrial operations, particularly communities of color, have historically borne disproportionate pollution burdens. Adding 57 unpermitted turbines to a neighborhood checks every box on that list.

Federal filings from May and June 2026 explicitly cite the government’s policy priorities: securing global leadership in AI technology while maintaining national security interests. The Pentagon’s confirmation that Grok operates on classified networks in support of active military operations transforms a local environmental case into something with geopolitical dimensions.

If courts accept that national security interests can temporarily override Clean Air Act compliance, that creates a template for any sufficiently connected tech company to delay environmental permits by demonstrating government contracts.

The xAI-SpaceX merger and the trillion-dollar question

xAI merged with SpaceX in February 2026, creating a combined entity that spans AI, satellite communications, and space launch. The merged company is planning an IPO later in 2026 with a target valuation of around $1 trillion.

Having the federal government publicly declare your AI model essential to national security signals durable government demand and suggests that Grok could become a long-term fixture in military and intelligence workflows.

If the court ultimately rules against xAI on the Clean Air Act violations, the company could face substantial fines, mandatory shutdowns, or requirements to retrofit pollution controls. Any of those outcomes could disrupt operations at Colossus 2 during a critical period before the IPO.
