Pentagon CIO Memo Ordering 180-Day Removal of Anthropic from Critical Systems
Internal Pentagon CIO memo orders 180-day removal of all Anthropic AI from nuclear weapons, missile defense, and cyber warfare systems — obtained by CBS News on March 10.
The Memo
On March 10, 2026, CBS News obtained an internal memorandum signed by Pentagon Chief Information Officer Kirsten Davies ordering the removal of all Anthropic AI systems from three categories of critical military infrastructure: nuclear command and control, missile defense networks, and cyber warfare operations. The memo establishes a 180-day timeline for complete removal and transition to alternative AI providers.
The memo acknowledges that Anthropic’s Claude models are currently embedded in “multiple mission-critical analytical and decision-support systems” across these domains and that removal “will require significant engineering effort and temporary capability degradation.” It directs program managers to identify replacement AI systems and begin transition planning within 30 days, with full removal completed by approximately September 2026.
Operational Implications
The memo reveals the extent of Anthropic’s integration into Pentagon systems that was not previously public. References to “nuclear command and control” and “missile defense” applications indicate Claude was being used in systems adjacent to or supporting nuclear deterrence operations — precisely the category of military AI deployment that Anthropic’s published responsible scaling policy addresses with the most restrictive safeguards.
The 180-day timeline itself signals the depth of integration. A system that could be removed in days or weeks would not require six months of transition planning. The memo’s own language about “temporary capability degradation” is an implicit admission that no current alternative provides equivalent capability for these specific applications.
The CBS News Reporting
CBS News reported that the memo was provided by a Pentagon official who described it as “the operational consequence of a political decision” and expressed concern that “we are being told to rip out systems that work and replace them with systems that don’t exist yet, on a timeline driven by a Truth Social post, not an engineering assessment.” The Pentagon did not dispute the memo’s authenticity but declined to comment on its contents, citing classification concerns regarding the specific systems referenced.
