Pentagon Memo Orders Anthropic Removal from Critical Systems
CBS News obtains an internal Pentagon memo ordering the 180-day removal of Anthropic AI from nuclear weapons systems, missile defense networks, and cyber operations infrastructure.
On March 10, 2026, CBS News published an internal Pentagon memorandum — marked UNCLASSIFIED//FOR OFFICIAL USE ONLY — ordering the removal of all Anthropic AI technology from three categories of critical military systems within 180 days: nuclear command, control, and communications (NC3); ballistic missile defense networks; and military cyber operations infrastructure. The memo, signed by the Under Secretary of Defense for Acquisition and Sustainment, established a phased removal timeline with monthly progress reviews.
The memo revealed for the first time the extent to which Claude had been integrated into the military’s most sensitive operations. Nuclear weapons systems, which had been understood to have limited AI involvement, were listed as requiring “significant reconfiguration” to remove Anthropic dependencies. Missile defense networks — including components of the developing Golden Dome program — were flagged as having “no currently qualified replacement” for certain analytical functions Claude performed. The cyber operations category encompassed both offensive and defensive capabilities across multiple combatant commands.
The document’s existence created an immediate tension with the Pentagon’s public position. If Anthropic’s technology was genuinely a supply chain risk to national security, the 180-day timeline for removing it from nuclear weapons systems seemed dangerously slow. If it was not a genuine security threat — if the designation was political — then the removal itself was degrading national security by eliminating a critical capability without a ready substitute. Neither interpretation reflected well on the Pentagon’s decision-making.
Defense analysts noted that the memo implicitly acknowledged what Anthropic had argued from the beginning: Claude’s integration into military systems was deep enough that removing it carried its own national security risks. The memo’s language about “no currently qualified replacement” for missile defense functions would become a central exhibit in Anthropic’s legal challenge and a key factor in the Pentagon’s later decision to open the door for exemptions.
