This doesn't change the results and there is plenty of support for the tech/aviation industy to promote exports.

Subsidies take many forms - look at exim.gov or just google Bell Helicopter or Boeing exim funding to see how many hundreds of millions have been provided through exim loan guarantees with extremely favorable terms to see how the US supports manufacturers. The funding is there but you have to have something that you can export and/or a more navigable path to funding access.
