Why Can't the U.S. Build Ships?
...
Another worrying indicator is shipbuilding capacity. Commercial shipbuilding in the U.S. is virtually nonexistent: in 2022, the U.S. had just five large oceangoing commercial ships on order, compared to China’s 1,794 and South Korea’s 734. The U.S. Navy estimates that China’s shipbuilding capacity is 232 times our own. It costs twice as much to four times 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.
...
To find a competitive American shipbuilding industry, you need to go back prior to the Civil War, to the era of wooden ship construction. The period from 1840 to 1860 is considered the golden age of American shipbuilding. Thanks to an enormous abundance of wood, and a long tradition of wooden shipbuilding, the U.S. built some of the fastest ships in the world in the form of packet ships and their descendants, clipper ships. When gold was discovered in California in 1848, most of it was brought back east via clipper ship. U.S. shipbuilding was commercially competitive enough that on the eve of the Civil War, roughly 2/3rds of America’s foreign trade was carried on U.S. ships.
...
But American shipbuilders were reluctant to transition to building steamships. They were experts in wooden ships, a technology that was still improving, and building a steam-powered metal ship required a totally different set of skills (more akin to what was needed to build a locomotive). Additionally, Britain had what seemed like an insurmountable lead given its proficiency in ironmaking and steam engine construction, a lead U.S. shipbuilders were reluctant to challenge. Thus, despite being the birthplace of the river steamboat, the US lagged behind in the construction of ocean-going steamships. Construction of sail-powered schooners used for coastal trade in the U.S. didn’t peak until the early 20th century, and in 1905 73% of the US’s ships engaged in foreign trade were sail-powered, compared to less than 20% of Britain’s.
...
And as with WW1, this exercise in rapid shipbuilding came at a cost. While American shipbuilding efficiency greatly improved during the war (man-hours per Liberty Ship fell from 1.1 million to just 486,000 on average), this was still far less efficient than the British, who could build a liberty-type ship with just 336,000 man-hours. Only a handful of the most productive U.S. yards could match British productivity.
Once again, the U.S. emerged from the conflict with an enormous merchant marine. While after WW1 it had amassed 22% of global shipping tonnage, the enormous scale of the WW2 shipbuilding machine meant that when the war ended the U.S. had 60% of the world’s shipping tonnage.
...
But the large block construction techniques the U.S. developed to build ships quickly didn’t die. Instead, they were brought to Japan by Elmer Hann, a former superintendent at a Kaiser shipyard during the war, now employed by Daniel Ludwig’s National Bulk Carriers. Ludwig wanted to build tankers of unprecedented size, which brought him to the Japanese shipyards at Kure, which had built the enormous battleship Yamato and emerged from the war largely intact. Hann brought his experience with large-block construction, and the Japanese quickly adopted and improved on the techniques, combining them with detailed assembly drawings used in aircraft manufacturing, group technology, and statistical process control methods introduced to Japan by Edwards Deming. Along with support from the Japanese government, large block construction technology allowed Japanese shipbuilding to rapidly improve, and by the end of the 1950s Japan had overtaken Britain as the largest shipbuilder in the world.
...
In the 1970s, there was a major attempt to reverse this decline in US shipping and shipbuilding, with the Merchant Marine Act of 1970. The act authorized funds for constructing more than 300 ships over a 10-year period, and extended the 1936 subsidies to encompass more types of ships. To try and incentivize shipbuilders to make their operations more competitive and efficient, subsidies were planned to gradually be reduced over time, from 50% of the cost of a ship down to 33%. The 1970 Act also led to the creation of the National Shipbuilding Research Program, which studied ways to reduce ship costs and construction times.
The result was “the largest peacetime shipbuilding program in U.S. history.” Shipbuilders spent more than a billion dollars modernizing their yards and making capital improvements. Japanese shipbuilding practices were studied, and Japanese shipbuilding firms were engaged to help bring their techniques back to the U.S. A large number of commercial ships were built: some of them, like the recently-invented Liquified Natural Gas carriers, without any subsidies at all. For a brief time, the U.S. was the second largest commercial shipbuilder in the world behind Japan.
...
In the 1990s, following the end of the Cold War and reduction in defense spending, a new government financing program for shipbuilders inspired some naval shipbuilders to try and enter the commercial game. When Newport News (a builder of aircraft carriers and nuclear submarines) tried to build several tankers for Greek shipowner Eletson, discrepancies during construction were so severe that Eletson canceled its contract; eventually, half of the ships were completed at twice the original estimate. Another naval shipbuilder, Ingalls, tried to build two cruise ships during this period, but soon they were so far behind schedule and so over budget that the unfinished hulls had to be towed to Germany to completed, requiring a special Jones Act waiver to allow them to serve U.S. ports once they were finished.

Plano de Navegação da Marinha dos EUA por Franchetti
O plano de navegação visa atingir dois objetivos estratégicos: preparar-se para uma potencial guerra com a China até 2027 e melhorar o longo vantagem de prazo da Marinha dos EUA.
Sete metas foram definidas:
• treinamento de forças, eliminando atrasos na manutenção de navios, submarinos e aeronaves;
• ampliar sistemas robóticos e autônomos para integrar rapidamente mais plataformas;
• criação de centros de comando no interesse da Marinha dos EUA para alcançar a vitória da frota americana num campo de batalha distribuído;
• aumentar o número de jogadores em campo;
• garantir a qualidade do serviço;
• preparação para operações de combate. A batalha acontecerá em ambientes reais e virtuais;
• restauração de importantes infraestruturas que permitem a projeção de operações de combate a partir da costa

Marinha dos EUA desenvolveu um novo sistema de guindaste para acelerar o processo de carregamento de mísseis em seus navios, resolvendo o problema de esgotamento de munição em conflitos potenciais - Wall Street Journal
Segundo o WSJ, os engenheiros da Marinha desenvolveram um protótipo chamado Transferrable Reload At -Sea Method (TRAM) que encurta o processo de recarga de mísseis de dois meses para vários dias . Espera-se que o sistema melhore a prontidão de combate dos navios da Marinha em cenários como um potencial conflito com a China no Estreito de Taiwan.
O TRAM opera sobre trilhos acima dos lançadores verticais de mísseis do navio e usa garras mecânicas para carregar contêineres de mísseis. Os mísseis são transportados do navio de abastecimento por meio de teleférico, com o TRAM sincronizando seus movimentos com os do navio.
