The European system often contain some American components. Perhaps the French a bit less so.

This has turned out to be a major problem, as the US has used their re-export restrictions on components to block very significant parts of planned European military aid to Ukraine.

I speculate that there will be (already is) some extremely heavy investments in military tech R&D to remove/reduce dependence on American components going forward. As a continent, we can't have our hands tied like this in future conflicts.
