Our LPDs may be somewhat better, but I don't see either one as having viable ship-to-shore connectors to support an opposed amphibious assault.<br /><br />So China is basically copying two of our bad ideas.

To weld the materials together was only first obstacle, how to bend them into different shapes for the hull modules another major challenge for the Chinese shipyard. Developed the SKWB-2500 a three-dimensional digital controlled bending machine able to exert a pressure of 6,000 tons on a sheet plate, pic on site shows of what appears to be a 25mm plate being shaped?, which if understand correctly is thicker than used in Burkes, 2/3 inch plate?<br /><br />Shipyard had to network all the welding machines and link them to a large database, in order to precisely control the parameters of each welding spot, all the parameters pre-configured in each machine, including current and voltage, and the system will automatically stop welding and man's work if things go out of tolerance.

To the outside wor...@Anonymous: Pretty much, yes. <br /><br />To the outside world it seems that China has recapitalised their fleet overnight, but that's not really the case; what we're seeing is the results of the last 3 decades or so of development work, which has had its own delays that we're not as cognizant of because the Chinese don't trumpet news like the US. Consider Liaoning - according to the Chinese carrier roadmap they laid down in 1987, they were supposed to have the basic R&D done by 1999, but they missed that target date by a decade-odd: talk about schedule slip!<br /><br />Naval shipbuilding wise, the last 3-odd decades have basically been them throwing things at the wall and observing naval shipbuilding trends, and the small numbers of ships they've built have essentially been used basically to test out the concepts and designs and see whether things work for them. As you note, they've now settled on what they want their DDGs to look like, and are now going full steam ahead with their finalised designs. In that respect, the USN head start, while advantageous in the beginning, also served the PLAN by giving them an idea of where they should be looking towards.WIld Goosehttps://www.blogger.com/profile/16911145032644199127noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-62497860233628019612019-02-28T15:42:40.585-08:002019-02-28T15:42:40.585-08:00@Wild Goose.

China's narrative has always been that it's one of the great powers, that it's a player on the world stage - it's doing this as a statement: "See, I am the Chinese Dragon, hear me roar, I am as power as the United States Navy." <br /><br />That said, the expectation is less that this is for use in SEA, and more for China to project power into Africa, as a way of guarding its interests, and having this big stick of overkill to keep African nations in line. An African dictator might think that his army might have a chance against a chartered cargo ship. He'd think twice about fighting a Chinese amphib group dropping tanks on the beach, flying gunships overhead.WIld Goosehttps://www.blogger.com/profile/16911145032644199127noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-4774867955931469362019-02-27T18:39:00.369-08:002019-02-27T18:39:00.369-08:00"What's surprising to me is that their am..."What's surprising to me is that their amphibious forces have lagged behind so much for so long."<br /><br />@DarthAnubis: My take, which I've talked about before, is that it was a matter of prioritisation.

Taiwan is not going to be an uncontested landing. Ho Chi Minh city is not an uncontested landing. Retaking their bases in the SCS if they get "liberated" will not be an uncontested landing (barring a complete failure in US strategic thinking). Okinawa and Kunsan are not uncontested landings. I'd rather China never attempt any of that, but strictly speaking, those could all be legitimate objectives if a (perceived) existential threat to their nation is using any or all of those locations to project power.<br /><br />What's surprising to me is that their amphibious forces have lagged behind so much for so long. All of those targets (and many more!) have existed for a long time, and any major conflict would have necessitated strikes (if not assaults) against them. Perhaps China just genuinely believed a major conflict was unlikely until now because it had a sufficient deterrent to prevent unprovoked conflict... and this is their tacit recognition that they're provoking conflict, with hegemonic intent or otherwise.Darth Anubishttps://www.blogger.com/profile/03007164480607753952noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-43092508501021141722019-02-27T13:14:00.749-08:002019-02-27T13:14:00.749-08:00All that you say about areas and uses is reasonabl...All that you say about areas and uses is reasonable.
