>Boeing DOD contracts
This is probably the closest comparison to what China is doing. But it’s still not the same thing because the US buys equipment from Boeing, they don’t just give them direct subsidies.

To the extent that the US pursues policies that help defense companies. They don’t do it in order to help those companies compete in foreign markets. They do it because they want those companies not to go out of business for national security reasons, or because they want those companies to provide domestic jobs.
The US does other shady things, but spending massive amounts to help domestic companies outcompete foreign companies in foreign markets isn’t one of them.
