This applies for any manufacturing industry to be honest. US shipbuilding capability is so limited compared to China. It's only surviving because of military spending, but not in a healthy way. US made ships are of lower quality and cost much more, compared to European countries. It's the same for cars, busses, airplanes. Whole US policy is blocking the entry of busses manufactured outside NAFTA. US government is keeping Boeing alive by sending POTUS to marketing trips etc etc.
