Tech firm blacklisted for defying US War Department demand to lift limits on surveillance and autonomous weapons
Artificial intelligence developer Anthropic has sued the Pentagon and Secretary of War Pete Hegseth, challenging the Trump administration’s decision to designate the company a national security risk and blacklist its technology across the federal government.
The complaint, filed Monday in the US District Court for the Northern District of California, argues that the administration overstepped its legal authority and retaliated against the company for refusing to remove safeguards governing how its artificial intelligence systems could be used by the military.
Anthropic is asking the court to declare the government’s actions illegal and block the actions, which it says threaten “Incorrigible” Harm to one of the worlds “fast growing” And more “responsibility” AI companies.
The legal battle has resulted in the company refusing to lift restrictions preventing its models from being used for mass domestic surveillance or fully autonomous weapons.
On February 27, President Donald Trump ordered federal agencies to stop using Anthropic technology, which he accused of conducting. “Leftwing nut jobs.” Shortly thereafter, Hegseth formally designated the company a “Supply Chain Risk to National Security” A label usually reserved for organizations linked to foreign adversaries.
The government argued that the company had refused to modify its models so they could be used “All legitimate military purposes” It creates operational risks by giving private contractors leverage over battlefield decision-making. Anthropic’s lawsuit disputes that characterization, saying the administration’s actions are punitive retaliation over policy disagreement about AI governance.
The company was previously the only AI developer authorized to deploy large language models on classified Pentagon networks, where its cloud system supports intelligence analysis and operational planning under contracts worth $200 million.
Cloud reportedly played a key role in planning and executing attacks targeting Venezuelan President Nicolas Maduro — as well as US-Israeli attacks on Iran that began just hours after Trump blacklisted the company.
Under the administration’s order, federal agencies were instructed to phase out the technology within six months while transitioning to alternative AI providers. Anthropic said continued reliance on its systems during that period undermines the government’s claim that the company represents an immediate security threat.
