A federal appeals court upheld the Pentagon's blacklisting of Anthropic as a supply-chain risk, a win for military control over AI during wartime operations.
A federal appeals court in Washington, D.C., ruled 2-1 on Friday to uphold the Pentagon’s effective blacklisting of Anthropic, the artificial intelligence company behind the Claude platform, as a national-security supply-chain risk. The decision clears the way for the War Department to bar Claude from Defense systems and contractors.
The Washington Examiner reported the panel’s ruling leaves the March designation in place and rejects Anthropic’s effort to block it. The fight centers on who sets the terms when private AI tools touch military operations: the company writing safety rules, or the officials charged with winning wars.
For taxpayers and service members, the stakes are concrete. If a commercial model can refuse missions the Pentagon deems necessary, readiness becomes hostage to a vendor’s policy choices. The court sided with the government on that point.
In March, the War Department listed Anthropic as a supply-chain risk under the Federal Acquisition Supply Chain Security Act of 2018. Defense Secretary Pete Hegseth ordered the exclusion after the company refused to allow its products for autonomous weapons or mass surveillance.
Pentagon officials argued those guardrails could compromise military operations. They warned that overly constrained models might shut down unexpectedly in the middle of a mission. That concern drove the designation and the push to remove Claude from Defense Department systems and contractor work.
Anthropic framed the dispute as retaliation for its safety stance. The company sought court relief to stop the blacklist while the case moved forward. A California federal judge had earlier found the Pentagon’s labeling inappropriate. The D.C. Circuit reversed that momentum.
The Just the News account notes the appeals court affirmed the Secretary’s national-security determination and the statutory authority behind it. The ruling restores executive room to balance competing risks without a tech firm writing the rules of engagement for its own code.
That same insistence on executive control has shaped other Trump administration fights, including the push to enforce the Pentagon’s ban on transgender troops through the courts.
Reuters reported the 2-1 decision handed a clear win to President Donald Trump and Defense Secretary Pete Hegseth. Judge Gregory Katsas wrote for the majority. He and Judge Neomi Rao, both Trump nominees, formed the controlling side.
Katsas described the government’s worry in blunt terms. The Secretary, he wrote, raised “the deeply sobering prospect of overly constrained AI models shutting down unexpectedly and thus causing important military operations to fail.”
The majority found ample support for treating continued integration of Claude as a covered national-security risk. Anthropic’s own restrictions supplied the basis. The court rejected the claim that the designation was improper retaliation.
In the majority opinion, Katsas wrote that the Department “reasonably feared that Anthropic might manipulate Claude’s design to prevent it from performing national-security functions that the Department deems contractually authorized and necessary.”
Breitbart noted the ruling allows the Pentagon to remove Claude models and bar their use in Defense work. Pentagon spokesman Sean Parnell called the outcome complete validation of the Department’s position.
The court put the constitutional assignment plainly: in this Republic, the President and the Secretary of War must decide how best to balance competing risks. The Secretary did not transgress limits under the Supply Chain Security Act or the Constitution.
Readers tracking the administration’s broader enforcement posture will recognize the pattern in moves such as the deportation of more than 25,000 people to third countries since taking office, another arena where executive judgment met courtroom challenge.
Anthropic also sought a stay pending full review. The D.C. Circuit denied it. The panel weighed limited financial harm to one private company against judicial management of how the War Department secures vital AI during active military conflict.
The order stated the equitable balance cuts in favor of the government:
"In our view, the equitable balance here cuts in favor of the government. On one side is a relatively contained risk of financial harm to a single private company. On the other side is judicial management of how, and through whom, the Department of War secures vital AI technology during an active military conflict. For that reason, we deny Anthropic’s motion for a stay pending review on the merits."
Fox News reported the court ordered expedited review on the merits while leaving the designation in force. Acting Attorney General Todd Blanche framed the stay denial as a victory for readiness.
"Today’s D.C. Circuit stay allowing the government to designate Anthropic as a supply chain risk is a resounding victory for military readiness. Our position has been clear from the start, our military needs full access to Anthropic’s models if its technology is integrated into our sensitive systems. Military authority and operational control belong to the Commander-in-Chief and Department of War, not a tech company."
Blanche’s point lands where it should. When AI sits inside sensitive systems, the chain of command cannot run through a corporate safety board. Operational control belongs with the people accountable for outcomes on the battlefield.
That priority has also collided with Capitol Hill resistance, including when Senate Democrats blocked a must-pass Pentagon bill in a rare break with decades of tradition.
The 2-1 decision settles the immediate fight over the stay and the supply-chain designation. The War Department may keep Anthropic off the defense supply chain and pull Claude from systems and contractor pipelines while the merits case proceeds on an expedited track.
It also settles a larger principle for this dispute: private firms that want defense dollars do not get to revise the missions those dollars fund. Safety guardrails that sound prudent in a lab can become single points of failure when the mission is live.
Open questions remain on the absolute calendar date beyond “Friday,” the full docket identity, and the final merits opinion still to come. The panel’s stay analysis and the majority’s national-security findings already give the government the operational green light it sought.
The administration’s pattern of pressing contested policy through the courts continues elsewhere, from refugee admissions caps to other national-security lines. One related track is the decision to cap 2027 refugee admissions at 17,500, another exercise of executive priority under legal fire.
Anthropic built Claude with deliberate limits. The Pentagon decided those limits made the product a risk inside its own networks. A federal appeals court agreed the government gets to make that call.
When commercial AI meets wartime systems, the Commander-in-Chief, not the vendor, sets the terms. That is how a republic keeps control of its own arsenal.
