I believe the bottleneck is personnel and operation and tactics. These 075s are their first LHDs. They'll start to build new batches after a while I suppose.
I'm just curious since I haven't seen any hard numbers, but how many boots on the ground would china need to put into Taiwan to do a successful amphibious assault and take the island? Like assuming Taiwan fights to the end and doesn't fold instantly to the overwhelming bombardment from sea and air? China needs to assume Taiwan will do the same as Ukraine, with them handing out weapons to everyone who wants one, and needs to expect that other countries will join the fight if it lasts longer than a month. Most of china's wars like vs India in 62 and vs Vietnam in 79 have lasted about a month or two max. That should also apply to Taiwan, or at least should be the goal. Of course once it kicks off, there is no retreat or limited offensive only, since Taiwan is part of china and china cannot afford to lose such a war since another chance won't come easily and if china already paid the price of entry(sanctions/economy/reputation/lives/equipment etc), they might as well stay till the end of the show and get their money worth.
Wouldn't china need like hundreds of thousands at minimum? China's current navy troop level is nowhere near that size, right? Or the air borne troops. So it would have to be a cross domain thing involving land army and every branch combined.
As such, China needs to train all the land army to be "dual purpose" and be capable of airborne assaults and amphibious assaults. If we compare vs how hard the Taiwan kids train, like 4 months only for one time in their life, vs full time professional soldiers, they could train and practice this kind of stuff regularly, just do it rotation.
After they've done a few air drops I assume it would be like riding a bike, and they would be able to pull it off in future no worries even if they haven't done it for months or years.. So they don't need to keep doing such training regularly for the whole army but at least everyone in the whole army should do it once or a few times at least. Or at least for those who are going to be used on the frontlines, ie all the infantry at least. Not just special forces or elite airborne troops which number max few tens of thousands which I doubt would be enough to the job. This would also help "future proof" them, since such skills would also come in handy if ever it's needed for vs Japan, south Korea, Vietnam, phillipines, SCS islands, whatever.
Imo if they are going to attempt amphibious assault, it should be with completely overwhelming force and numbers, including with missiles galore destroying everything of worth on the surface. None of this half assed stuff like Russia is doing which only prolongs the suffering and gives Taiwan and china's enemies more time to hurt china. China gets the massive advantage to pick the time and place to fight, or not fight at all. So if they are going to fight they should not waste their tactical, strategic, qualitative and numerical advantages and should maximize them all.
Of course, Taiwan can't really be compared with Ukraine since Ukraine just ran away to hide in the cities, with occasional attacks on overstretched convoy lines. If Taiwan employed such a strategy, that would just allow china to establish beachheads and landing spots, and if that happens they've already lost. So maybe china doesn't need to level all of the urban areas before they put boots on the ground but if they don't surrender instantly once china has boots on the ground that will be the next step up. But like I said it should be done in 1-2 months ideally. If things take longer it could get dangerous and give time for outside forces to interfere or even intervene.
