The Pentagon has stopped using Anthropic's AI tools, an official confirmed to the BBC, months after the company was placed on a national security supply chain blacklist. Defence Secretary Pete Hegseth designated Anthropic a supply chain risk in February and set a deadline for removal by late August. The department said it has now 'ceased the use of Anthropic products' following a review.
Multiple sources told the BBC that Anthropic's Claude model remained embedded in the Pentagon's Maven Smart System as recently as last week. The system, operated by Palantir, serves as the department's primary platform for organizing intelligence data, including satellite imagery and drone footage. Analysts used Claude through Maven for tasks such as identifying potential military targets and generating briefing documents.
Lauren Kahn, a senior research analyst at Georgetown's Center for Security and Emerging Technology, noted that removing Claude required more than a simple software update due to its deep integration with existing workflows. 'Once these tools become part of the system, extraction can be difficult,' she said.
The shift follows a dispute in which the Pentagon demanded Anthropic remove safety guardrails from Claude to allow unrestricted military use. When the company declined over concerns about mass surveillance and autonomous weapons, it was added to the blacklist. The Pentagon has since signed contracts with other AI firms, including Google, xAI, and OpenAI, which have seen broader adoption in recent months.
Anthropic declined to comment on the Pentagon's statement. The company had previously worked with U.S. government agencies since 2024, becoming the first advanced AI firm to deploy tools in classified government work.
The development comes as relations between Anthropic and the White House appear to improve. Former President Donald Trump met with Anthropic CEO Dario Amodei twice last week, praising the company's work while acknowledging ongoing discussions about AI risk mitigation. Amodei stated that collaboration with the administration could help address safety concerns while advancing national objectives.
