They've created a market in which a US based company cannot compete economically, because the cost of production elsewhere will be less. There is no margin by which any competition can take place, whether or not the government throws a ton of money and stopgap incentives into the mix.
You can't manufacture chips, small household goods, general purpose clothing, electronics, or a whole slew of other things in the US because our legal regime fundamentally disallows any American participation in those markets through economic disincentivization. If you can't make any profit because you have to pay higher wages or taxes if you manufacture in the US, then you're not going to manufacture in the US, even if you're a patriot.
The US doesn't have a rational system designed to maximize value to citizens, it's a hodgepodge of conflicting regulatory grifts designed to maximally benefit the corporations who paid for the lobby.

That's exactly what "globalizing" is. You literally cannot, under the current regulatory regime, create a ship building company that can compete with other established interests and competition from other countries. You'd have to relax the arbitrary labor and wage constraints, fix taxes and tariffs for sufficiently long term outlooks that anyone would bother investing. To achieve that, you'd need good faith operators throughout the government willing to rock the boat, and if you think that will ever happen, I've got a bridge in Brooklyn for ya - I'll sell it cheap.
