I'll put this in the Trump thread, but it also could go in the American Economics thread...
This seems like a big bet on American shipbuilding and probably the best chance America has had to enter the global commercial shipbuilding arena in... decades?
Obviously we don't know how this will play out, but this is a fairly significant investment by a world leading shipbuilder with commitment to training, infrastructure and firm orders.
I emphasized the annual production because that is a large number. 20 ships per year is probably greater than the entire current US commercial shipbuilding output.
