According to a statement, SpaceX, OpenAI, Google, Nvidia, Reflection, Microsoft and Amazon Web Services will be integrated into the Defense Department's most sensitive classified systems, used for mission planning, weapons targeting and other purposes.

The statement did not include Anthropic, which is caught up in a fight with the Pentagon over its demand for guardrails for how the military could use its AI tools.

The US military has been seeking to wean itself off Anthropic's AI due to the company's objection to its technology being used for mass domestic surveillance or as autonomous killing machines.

A furious Pentagon subsequently labeled the AI startup a supply-chain risk earlier this year, barring its use by the US military and its contractors.

Anthropic's AI model, Claude, was the only one authorized for use in classified operations within the US military and is still being used.

The announcement on Friday framed the deals with Anthropic's rivals as central to the Trump administration's push to build what it called an "AI-first fighting force."

The integrations would "streamline data synthesis, elevate situational understanding, and augment warfighter decision-making," it said.

The Pentagon said its GenAI.mil platform -- described as its official AI system -- had already been used by more than 1.3 million department personnel, generating tens of millions of prompts and deploying hundreds of thousands of agents in five months.
