The Department of Defense has argued that allowing Anthropic continued access to its warfighting infrastructure would introduce an unacceptable risk to supply chains and national security. In a court filing responding to Anthropic's lawsuit over a supply‑chain risk designation, the Pentagon cited concerns that the company could disable or alter its AI models during operations if corporate “red lines” were crossed. The filing notes that the agency’s secretary, Pete Hegseth, included a provision in AI contracts permitting use for any lawful purpose, which Anthropic refused, prompting the department to label the partnership unsafe.
Pentagon’s Security Concerns
The Department of Defense contended that granting Anthropic ongoing access to its warfighting infrastructure would "introduce unacceptable risk" to its supply chains, as detailed in a court filing responding to the AI company’s lawsuit. The filing explained that the department’s secretary, Pete Hegseth, had incorporated a provision into AI service contracts that allows the agency to use the technologies for any lawful purpose. Anthropic’s refusal to accept these terms raised doubts about its suitability as a "trusted partner" for highly sensitive initiatives.
The Pentagon warned that AI systems are highly vulnerable to manipulation. It asserted that Anthropic could potentially disable its technology or preemptively alter the behavior of its model before or during ongoing warfighting operations if, in its discretion, the company felt its corporate “red lines” were being crossed. The department deemed this scenario an "unacceptable risk to national security," referencing the agency as the Department of War, the name favored by the Trump administration.
Legal Conflict and Potential Impact
Anthropic sued the government to challenge the supply‑chain risk designation it received after refusing to allow its model to be used for mass surveillance and autonomous weapons development. The company is seeking a preliminary injunction to pause the ban while it contests the designation in court. The filing indicated that Anthropic’s clients could continue working with the company on non‑defense projects, but the label could cause the firm to lose billions of dollars in revenue.
While the filing did not clarify whether Anthropic is still pursuing a new agreement with the government, the New York Times noted that Microsoft, Google, and OpenAI had filed friend‑of‑the‑court briefs in support of Anthropic. The filing also referenced President Trump’s order for federal agencies to stop using Anthropic’s technology, underscoring the administration’s stance on the perceived security risk.
