That's before we discuss the advantage Boeing has in the commercial market thanks to DoD contracts.

Your link shows that the US exports the same as the next 20 countries added together. That suggests some market dominance.

I also suspect these numbers do not include "military aid" - where weapons and munitions are "given" by the US to Ukraine wherever[1]. (But they may, I don't know.)

I agree though that the primary benefit of this is not "sales". And even if it was these aren't consumer goods. So it's not easily compared to China's approach. I'm not suggesting it's a terribly good subsidy. But it's still a subsidy.

[1] there are a lot of political benefits to be gained by having bases in foreign countries, or by port visits by US ships. Unfortunately most of those benefits have been eroded in the last 2 years. The gutting of USAid (which saved basically nothing), leaving the WHO, the tarrif nonsense, bombing Iran - all have destroyed a benevolent reputation 75 years in the making.
