The Pentagon is moving to phase out Anthropic’s Claude AI. But military staff and contractors say the transition may not be easy. Some users are already resisting the change.
Defense Secretary Pete Hegseth recently labeled Anthropic a supply chain risk. The decision blocks Claude from use across Pentagon systems after a six month phase out period. The move follows a dispute over how the military can use AI tools.
However, many inside the military rely heavily on Claude. Contractors and officials say the tool has become central to daily operations. Some even describe it as more reliable than competing AI systems.
Replacing Claude could take significant time. Experts say recertifying new systems for military use may take months or even over a year. This could slow down operations and reduce productivity.
In some cases, tasks once handled by Claude are now being done manually. Officials say teams are using tools like Excel instead of AI. This has led to frustration among developers and analysts.
The situation highlights how deeply AI is now embedded in military workflows. Claude has been used for coding, data analysis, and even supporting operations. Its removal could disrupt ongoing systems and projects.
Some teams are delaying the transition. They expect the dispute between the Pentagon and Anthropic could still be resolved. If that happens, Claude may return before the phase out is complete.
For now, the Pentagon faces a difficult shift. It must balance security concerns with the growing reliance on AI tools across defense operations.
