Pentagon Used Anthropic’s Claude in Iran Operation Hours After Federal Ban

Operational reliance on Claude persisted after the ban due to its unique approval on classified systems.

Overview

  • U.S. forces used Claude for intelligence analysis, target identification and tactical simulations in the Iran campaign, according to Wall Street Journal reporting based on military sources.
  • The use reportedly occurred just hours after President Trump ordered federal agencies to cut ties and the Pentagon labeled Anthropic a defense supply‑chain risk.
  • Claude was the only AI model fully cleared for certain classified systems, and defense officials expect a months‑long transition to replace it across those workflows.
  • U.S. Central Command confirmed the first combat deployment of one‑way “kamikaze” drones during the campaign to overwhelm and disorient Iranian defenses.
  • Anthropic’s CEO refused to remove guardrails on mass surveillance and fully autonomous weapons, a stance that precipitated the rupture, while publicity helped lift the Claude app to No. 1 in the U.S. Apple App Store.
