The US is not capable of building these ships

For those of us worried about Americas ability to manufacture things, theres no shortage of worrying indicators to point to. Manufacturing employment has fallen by a third from its peak in 1979, even as the population has grown by nearly 50% over the same period. Storied manufacturing companies like Boeing and Intel are struggling. From machine tools to industrial robots to consumer electronics, the list of American industries where manufacturing capability has been hollowed out is long.
Another worrying indicator is shipbuilding capacity. Commercial shipbuilding in the U.S. is virtually nonexistent: in 2022, the U.S. built just five oceangoing commercial ships, compared to Chinas 1,794 and South Koreas 734. The U.S. Navy estimates that Chinas shipbuilding capacity is 232 times our own. It costs roughly twice as much to build a ship in the U.S. as it does elsewhere. The commercial shipbuilders that do exist only survive thanks to protectionist laws like the Jones Act, which serve to prop up an industry which is uncompetitive internationally. As a result, the U.S. annually imports over 4 trillion dollars worth of goods, 40% of which are delivered by ship (more than by any other mode of transportation), but those ships are overwhelmingly built elsewhere.
