US Military Stays With Claude as Defense Tech Clients Exit

The fallout from Anthropic's dispute with the Department of Defense has placed the company in a precarious position. Its technology is actively being used in the ongoing U.S.-Iran conflict, even as it severs ties with numerous defense industry clients.
This confusion stems from overlapping and contradictory U.S. government restrictions. While President Trump ordered civilian agencies to stop using Anthropic products, the company was granted a six-month period to phase out its work with the Pentagon. The very next day, a surprise U.S.-Israeli strike on Tehran escalated hostilities before the directive could be fully implemented.
Consequently, as U.S. aerial campaigns continue against Iran, Anthropic's models are informing numerous targeting decisions. Although Defense Secretary Pete Hegseth has vowed to label the company a supply-chain risk, no formal action has been taken, leaving no legal obstacle to the system's current use.
A recent Washington Post article revealed new details on how Anthropic's systems work alongside Palantir's Maven platform. During Pentagon strike planning, these systems reportedly "suggested hundreds of targets, provided precise coordinates, and ranked them by priority." The Post described this function as "real-time targeting and target prioritization."
Simultaneously, many defense-related firms have already switched from Anthropic to competing models. Lockheed Martin and other major contractors began replacing the company's technology this week. Numerous subcontractors face a similar dilemma; an investment firm partner told CNBC that ten of its portfolio companies "have halted their use of Claude for defense applications and are actively transitioning to alternative services."
The most significant unresolved issue is whether Secretary Hegseth will follow through on the supply-chain risk designation, a move that would likely trigger a major legal battle. For now, a leading AI lab is being rapidly edged out of military technology—even as its systems operate in an active theater of war.
