DOD Memo: Phase Anthropic Out of National Security Systems
An internal Pentagon memo dated March 6, obtained by CBS News, orders military leaders to remove Anthropic AI products from their systems within 180 days, with exemptions only for mission-critical work where no viable alternative exists. CBS also reports Claude is being used in the war on Iran, per sources. Escalation after the label — not a civilian ChatGPT ban.
Corrected October 14, 2026: Corrected the memo's terms to CBS News's report (removal within 180 days; exemptions only for mission-critical work where no viable alternative exists), attributed the Iran detail to CBS's sources, and removed sources that had not been checked. Re-dated to March 10, when CBS News published the March 6 memo; added the March 9 lawsuits as reported by CBS.
A supply-chain risk label is paperwork until someone orders uninstalls. The proprietary escalation: a March 6 internal DOD memo turning the Anthropic designation into operational removal from key national security systems.
Per CBS News reporting on the memo addressed to senior military leaders and commanders: agencies must identify and discontinue Anthropic models and services; national security concerns tied to the company’s refusal to relax safeguards for certain military applications; systems must be cleared of Anthropic products within 180 days, and exemptions will be considered only for mission-critical activities where no viable alternative exists, with a risk-mitigation plan approved by the CIO. CBS reports that Claude is being used by the U.S. military in the war on Iran, according to sources familiar with the military’s use of AI. Anthropic maintains safeguards are essential; most commercial customers unaffected; it filed two lawsuits on Monday, March 9, alleging the designation was illegal retaliation, CBS reports.
