Both the Washington Post and the Guardian articles agree that the system used here was Maven.

The key sentence in that Washington Post article appears to be:

> The Pentagon began to integrate Anthropic’s Claude chatbot into Maven in late 2024, according to public announcements.

As far as I can tell this is the public announcement - a press release from November 2024: https://www.businesswire.com/news/home/20241107699415/en/Ant...

> Anthropic and Palantir Technologies Inc. (NYSE: PLTR) today announced a partnership with Amazon Web Services (AWS) to provide U.S. intelligence and defense agencies access to the Claude 3 and 3.5 family of models on AWS. This partnership allows for an integrated suite of technology to operationalize the use of Claude within Palantir’s AI Platform (AIP) while leveraging the security, agility, flexibility, and sustainability benefits provided by AWS.

We know that Palantir used AI for target selection in Gaza:

We know that it integrated Claude and Claude was deemed to be a supply chain risk just before the Iran war. So it is not a huge mental leap to assume what it is being used for.

You won't get an answer from Hegseth. This Guardian "article" is by a Substack blogger who also does not have answers.

		That article you are quoting there is from April 2024. The Claude + Palantir deal was announced in November 2024. The "supply chain risk" claims came from a deeply non-serious executive team who don't like "woke AI". They're not credible.
