Pentagon memo orders commanders to remove Anthropic from key systems

▶ Watch Video: Pentagon designates Anthropic a supply chain risk as standoff over AI guardrails continues

The Defense Department has officially notified senior leadership figures throughout the U.S. military that they must remove Anthropic’s artificial intelligence products from their systems within 180 days, according to an internal memorandum obtained by CBS News.

The memo was dated March 6, a day after the Pentagon formally designated Anthropic a supply chain risk. It was distributed to senior leaders on Monday, alleging Anthropic’s AI “presents an unacceptable supply chain risk for use in all [Department of War] systems and networks.” 

The document, signed by Defense Department Chief Information Officer Kirsten Davies, represents the latest salvo in an escalating feud between the Trump Administration and Anthropic. The notice sheds light on the wide-ranging steps military commanders will need to take to remove Anthropic AI from key national security systems, including those for nuclear weapons, ballistic missile defense and cyber warfare. 

It also demanded that any other company doing business with the Pentagon must stop using all Anthropic products on work related to Defense Department contracts within 180 days.

In the memo, Davies warned that adversaries “can exploit vulnerabilities” of the daily operations of the Pentagon, and possible exploitation could pose “potential catastrophic risks to the warfighter.” Davies said she is the only one who can grant an exception.

“Exemptions will only be considered for mission-critical activities directly supporting national security operations where no viable alternative exists, and the requesting Component must submit a comprehensive risk mitigation plan for approval,” she wrote.

A senior Pentagon official confirmed the memo’s authenticity.

Anthropic did not immediately respond to a request for comment.

The federal government’s action is said to be unprecedented — the first time an American company has been designated a supply chain risk. During President Trump’s first term, the government took similar action to restrict foreign-based companies like Chinese telecommunications giant Huawei.

It comes after an impasse over Anthropic’s request for two “red lines” that would explicitly prevent the U.S. military from using its Claude model to conduct mass surveillance on Americans or power fully autonomous weapons. 

“We believe that crossing those lines is contrary to American values, and we wanted to stand up for American values,” Anthropic CEO Dario Amodei told CBS News. 

The Pentagon previously said it  wanted to be able to use Claude for “all lawful purposes,” without restrictions, arguing that the uses of AI that Anthropic is concerned about are already prohibited. Claude is currently being used by the US military in the war on Iran, according to sources familiar with the military’s use of AI.

Anthropic is currently the only AI company whose models are deployed on the Pentagon’s classified systems. After talks between the two sides broke down last month, one of Anthropic’s largest rivals — ChatGPT creator OpenAI — said it had signed a deal with the Pentagon.

On Monday, Anthropic filed two lawsuits against the federal government, alleging that Pentagon officials’ decision to deem the company a supply chain risk amounted to illegal retaliation. 

“The Constitution does not allow the government to wield its enormous power to punish a company for its protected speech,” the company said in the lawsuit. “No federal statute authorizes the actions taken here.”

White House spokesperson Liz Huston responded to the lawsuit by saying President Trump “will never allow a radical left, woke company to jeopardize our national security by dictating how the greatest and most powerful military in the world operates.”

A source directly familiar with Claude’s military capabilities told CBS News the main task Claude is undertaking for the military is sifting through large amounts of intelligence reports, like synthesizing patterns, summarizing findings, and surfacing relevant information faster than a human analyst could. 

“The military is now processing roughly a thousand potential targets a day and striking the majority of them, with turnaround time for the next strike potentially under four hours,” said  retired Navy Admiral Mark Montgomery, now a senior director at the Foundation for Defense of Democracies. “A human is still in the loop, but AI is doing the work that used to take days of analysis — and doing it at a scale no previous campaign has matched.”

The US Navy’s plan for almost 20 guided-missile subs and why that will matter around China

By CNN
(CNN) — The US Navy this week announced a “pivotal shift” in its future submarine force, and it’s a move analysts say provides important insights into how Washington would fight any possible conflict in the Pacific, where China is rapidly building up its forces.The Pentagon announced that 19 planned nuclear-powered Virginia-class attack submarines (SSNs) would now be classified as guided-missile submarines (SSGNs) and fitted with the Virginia Payload Module (VPM), an 84-foot-long section which adds 28 missile-launch cells to the 12 on current versions of these subs.Those cells can be loaded with Tomahawk land-attack missiles as well as hypersonic vehicles. Combined with the stealthy abilities of submarines, this will provide the new boats with a crucial ability to get inside China’s missile defenses, analysts say.“Submarines are one of the few capabilities which can loiter forward, near or within the first island chain in relative safety,” said Sidharth Kaushal, senior fellow at the Royal United Services Institute (RUSI) in London, referring to the string of islands from Japan southward through Taiwan and the Philippines, inside of which Beijing can bring the most firepower to bear.“Second, hypersonic missiles represent a capability against which US adversaries – which otherwise enjoy robust air defenses – have more limited defenses,” Kaushal said. And getting the high-speed, maneuverable missiles closer to their targets strains adversary reaction time.Key strike platforms being retiredThe details of the new sub plan come at a critical time for the Navy.This year it is beginning to retire its four Ohio-class guided-missile subs. Those boats were converted to SSGNs 20 years ago from their nuclear deterrent role as ballistic-missile subs, or boomers, after the US and Russia reduced their nuclear forces with the 1993 START II treaty.Once armed with nuclear-tipped Trident ballistic missiles, the four reconfigured Ohio-class subs can carry up to 154 Tomahawks each, and have been prized assets for deterrence and combat missions around the globe.Speaking to CNN in 2021, Bradley Martin, a former Navy captain turned naval researcher at the RAND Corp think tank, called the Ohio-class SSGNs “the platform with the single largest ability to deliver conventional missile payloads.”During the 2025 Operation Midnight Hammer strikes on Iranian nuclear sites, an Ohio-class boat was called upon to augment B-2 bomber strikes.But one of the four Ohio-class SSGNs, the USS Georgia, began its deactivation process last month and the other three are scheduled to do the same over the next several years.Retirement of those boats will reduce the Navy’s undersea strike capability by up to 60%, according to the Washington, DC-based Submarine Industrial Base Council.The first of the Virginia-class SSGNs are not scheduled to join the fleet until 2029, so the Navy is likely to see a shrinkage in its missile strike capabilities in the meantime. The last of the new subs isn’t due to join the fleet until 2038.Current inventory includes at least 24 smaller versions of the Virginia class as well as around 20 older Los Angeles-class subs and three specialized Seawolf-class boats, so the Navy is not without conventional sub-launched missile capability.In the long run, leaders are confident the 19 new boats will prove suitable replacements for the Ohios.“These VPM-equipped SSGNs will ensure the Navy continues to dominate the undersea domain for decades to come. By integrating this additional payload capacity, we will have the ability to surge strike power to assure our allies, deter aggression, outmatch any adversary,” Vice Adm. Rob Gaucher, director of submarine programs, said in a statement.“Georgia and her sister ships proved the enduring value of combining undersea stealth with unmatched clandestine strike capability,” the chief of naval operations, Adm. Daryl Caudle, said.“The next generation of Virginia-class SSGNs builds on that legacy with greater survivability, adaptability, and sustained combat power,” Caudle added.Not a one-for-one swapAnalysts caution that the move from the Ohio class to the Virginia class is not a one-for-one trade, as a single Virginia-class sub will carry only about 26% of the missiles of an Ohio-class one. That means it will take four future boats to equal the firepower of one currently.Analyst Bryan Clark, a Hudson Institute senior fellow and former Navy officer, notes another key difference between the two – the Ohio class has two rotating crews while the Virgina class has only one, meaning the former could spend twice as long actually on patrol.But being able to disperse missiles over a greater number of platforms has its advantages, says Alessio Patalano, professor of war and strategy at King’s College, London.“They expand the number of platforms that can bring the fight deep into an enemy’s territory, and as such opponents will have to contend with more assets they have to track, or at least try to,” Patalano said.It’s a key point in any possible conflict over Taiwan, the democratically governed island that the Chinese Communist Party claims as sovereign territory despite never having controlled it.China has been in the midst of an aggressive submarine-building program in recent years.According to a February report from the International Institute for Strategic Studies, the PLA Navy ramped up its production of nuclear-powered submarines over the past five years to the point where it is launching subs faster than the US, threatening to negate a sea-power advantage that has long belonged to Washington.From 2021 to 2025, China’s submarine building surpassed that of the US in both numbers of subs launched – 10 to 7 – and tonnage – 79,000 to 55,500, says the report.In an attack sub configuration, that’s more hunters of US subs in regional waters.Beijing has been rapidly building its missile forces, too.In December 2024, the Pentagon estimated that China’s rocket force had boosted its missile supply by 50% in the preceding four years.The People’s Liberation Army wants “to set the conditions for the invasion of Taiwan,” Decker Eveleth, an associate research analyst at the non-profit national security group CNA and an expert on China’s missile forces, told CNN last year. “So that’s shooting at ports, shooting at helicopter bases, shooting at supply bases … shooting at anything that can theoretically let you bring support to Taiwan.”“They want to destroy things in theater and keep everything else out,” Eveleth said.This buildup comes at a time when the US military’s own munitions stockpiles have seen significant depletion since President Donald Trump’s decision to join Israel and bomb Iran.Close-in operationsAnalysts said the new Virginia-class subs help negate China’s missile advantage, especially in the early days of any conflict.US subs that can get inside that first island chain would be in prime position to take out radars and command posts that would be coordinating defenses and helping Chinese missile targeting, analysts said.That could “degrade an adversary’s anti-surface capabilities to a level sufficient to enable other platforms such as surface ships to be moved forward at less risk, thus setting the conditions for aircraft carriers to provide follow-on strikes,” RUSI’s Kaushal said.Hypersonic launch capabilities enhance the new Virginia class further, analysts said, noting that testing of a hypersonic glide vehicle is well underway.They help give the newest Virginia class “a genuine uplift in the strike function,” said Patalano at King’s College.“That’s what gives an adversary an extra moment of pause,” he said.What can’t be forgotten, however, is that China won’t be standing still.At a military parade in Beijing last fall, China showed off a dizzying amount of new missiles, including a range of hypersonic vehicles, that many analysts say put the PLA at the forefront of that technology.Also in the parade ranks were new uncrewed submersible vehicles – underwater drones, stealthy in their own right, that could pose a threat to any of Beijing’s adversaries.The realities of that are surely obvious to the US Navy. But its leadership retains confidence in an area where it has been unmatched since World War II.“Armed with state-of-the-art sensors, unmatched stealth, and advanced automation, these reclassified SSGNs will operate with impunity in contested waters, ensuring the United States Navy maintains absolute undersea supremacy,” a Navy statement said.The-CNN-Wire™ & © 2026 Cable News Network, Inc., a Warner Bros.
