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.
