it would come down to: does the west have the willingness to actually have government operated cargo ships send supplies, because civilians aren't going to run a blockade

it would be reasonably difficult to entirely cut off taiwan with just land based ASMs if they were escorted (having to go over taiwan would mean being the missiles are spotted and engaged by anti-air defenses for a very long time, or going around the island dramatically reduces available fuel for a final sprint phase) while trivial if they were not (the risk being present at all would invalidate maritime insurance and bankrupt any company dumb enough to try)

The PLAN probably wouldn't actually be handling blockade duties itself rather it would be Chinese coast guard/militia that nevertheless would have to be cleared out. One way or another it would take the USN to be psychically present in the engagement zone to make a difference.

Also, I would say the second Taiwan starts opening up on Chinese missiles, the PLA will start knocking out their missile defense batteries and I don't think Taiwan can do much about it.

there’s really only one country worldwide that has that ability, it’s the US’s RRF. I used to be part of the list that would get called up for that. it’s a weird program. those ships are getting long in the tooth though, I’ve seen some talk of getting new ships into the program.

but in a real war there is another option. they can just take civilian ships. most countries and the US especially have laws for that. just straight up it’s in our port that’s ours now.

the small problem here is that there are three countries that account for about 90% of the world's merchant shipbuilding, and those are japan, south korea and china itself

so in other words the us will have no real way to replace sunk freighters because those japanese and korean shipyards are sure as hell going to be a priority target for china if the poo poo hits the fan

Semper Shitpost Ubique

gradenko_2000 posted:

the thing about nuclear submarines is that you cannot turn off the reactor, so there's always some machinery running and, by extension, always some noise

there are ways around this, but the main one is the thermocline, or the point where there's a sudden drop in ocean temperature due to limits on how far the warming of the sun can penetrate into the water. The thermocline acts as a sort of sound barrier: active sonar will bounce right off of it, and even passive sonar has issues, because if the sound you're hearing has bounced off the thermocline at some point, the thing might be nowhere near where you think it is

but a thermocline doesn't show up in very shallow water - you need something like 500 to 750 meters of depth to get a seasonal thermocline in the tropics, and anywhere from 1,000 to 2,000 meters of depth for a permanent thermocline

the Taiwan Strait is almost entirely shallower than 150 meters

and you don't even get deeper than 2,000 meters until you're well away from the continental shelf (as in the map in the tweet)

and that's not factoring in the problem of a lack of maneuverability on the horizontal plane

___

but what if you're NOT a nuclear submarine?

the drawback of a diesel-electric submarine is that the electric batteries run out, and when they're out, you need to run on (or near to) the surface with a noisy diesel engine

the advantage is that while you're running on batteries, you can be a black hole of sound. You can stop all moving machinery, and just lie at the bottom

this works even better when you're in littoral waters, because it's so noisy from all the marine life and the extant traffic and the waves bouncing all around the relatively shallow pool of water that it's hard to make heads or tails of anything, and especially if you yourself are barely making any noise at all

the one thing that might still work is active sonar, since no amount of silence is going to make your sub any less of a big hunk of metal that a ping will bounce off of, but the guy looking for you has to know that you're there first

so you plunk yourself down at the bottom of the ocean, turn everything off, wait for a big juicy supertanker to pass over you, and take your shot

once you shoot, you're almost certainly going to die, because now they know you're there, and you've put yourself in a position where you have limited space to maneuver, and if you're operating deep, you're still running on those batteries, which means you're on a short leash even if you could maneuver

but the ROI of a diesel-electric sinking a supertanker, or a big America-class landing ship, or even a fleet carrier, will be repaid several times over, as long as you can pull off what is essentially planting yourself as a sapient sea mine. And if you were a nuc, you'd never have been able to make that shot in the first place

the United States Navy built its last diesel-electric submarine in 1959

This man read the littoral waters naval operations textbook they made us read before RIMPAC.

What he said.

Taiwan's not only in antiship missile range of the mainland, it's also been in range of China's 370mm rockets for a while and the PLA also has even larger rockets if they have to resort to dumb munitions.

If that's too old fashioned then there's the whole arsenal of suicide drones/loitering munitions from the mainland and the usual armed ucavs that make having no air defense unbearable.

Edit: So waiting for China to run out stuff to shoot is a fool's game from the get-go because the PLA has plenty of more replaceable options that they can reserve missiles for valuable warships/planes if they have to.

no one in Asia (including the Chinese) will be building merchant ships in this scenario. Just assume no country is replacing … really most of anything.

also an invasion and blockade of Taiwan means China isn’t importing commodity grains anymore by vessel from anywhere.

Ardennes
May 12, 2002
If anyone wants the numbers, China imports 65 million tons of grain/flour year, if you divide that by 356, that is 182,584 tons per day. If you had an above average train bringing (3,000 tons per trip) of just grain it would take 60 of them of them a day.

For no reason in particular: Ukrainian pre-war grain exports were around 45-55 million tons per year.

Bar Ran Dun
Jan 22, 2006




There is not (and will not be ) rail capacity for that btw. The more useful transport unit to have in mind is 66,000 tons per Panamax at thier ports draft restrictions. which is about three per day.

and most is soy and corn not wheat.

Ardennes
May 12, 2002
China is actually the world's largest producer of wheat, they just don't export much of it. I would assume during war-time there would be some degree of changes in diet (also China is mostly self-sufficent).

The question of rail through-put is another factor, but at the same time, part of the reason for belt and road was to establish durable rail connections across Eurasia and it has mostly worked. Obviously, a panamax ship is going to be more efficient, but again we are talking about wartime.

it’s also not a question of efficiencies. the vessel transport isn’t replaceable in magnitude by train period. that’s actually playing out right now with the Ukrainian grain exports btw.

90% of grains consumed in China are produced there though, so on one hand yes, but on the other hand, it may not matter especially if there are conpensating mechanisms in place. Also, China exports more food as well, and the deficit from imports would be mitigated by a cap on exports.

China has clearly been planning on such an eventuality for a while.

Bulk food imports (including grains) seem to have begun to reduce whereas imports of stuff like meat, dairy, and horticultural products has massively increased. so yeah there is definitely a danger of a big hit to certain foods availability in the event of a war and that of course comes with the danger of unrest.

The goal of the Chinese is to be around 85% self sufficient in beef and 70% in dairy, and again they also have rail and road connections.

Btw, a lot of "buying up that capacity" is Chinese nationals intermarrying and then purchasing land and staying there and raising a family. I don't know how you want to frame that one. As far as fishing again, I don't know I would square aggressive fishing practices with imperialism to be honest without making the world useless. Also, you can save the articles about debt traps etc.

No one knows when a war is going to happen (or if anything China if they could would time it after their granaries are filled). The question isn't it would fully satisfy their current consumption, but rather it would satisfy it enough that there wouldn't be serious unrest or other issues. China already has an very robust domestic agricultural production, and imports are for the most part a much smaller part of that. The logistics involved is not about feeding the entire Chinese nation, it is about assuaging the fall in imports from sea lanes. At the same time, do you really think the Chinese can not in the slightest increase their capacity for inland imports? That the Russians wouldn't at least attempt to address any all in imports?

Danann posted:

Also, US shipyards are dramatically underperforming despite money being thrown at them. They can out of produce 2 Arleigh-Burke destroyers out of 3 proposed, and 1.25 Virginia class subs out of 2 proposed per year; the Chinese are rapidly expanding their shipyards at the same time.

Much of the US subfleet is still old Ohio/Los Angeles class subs from the 1970s/80s to early 1990s.

The Russians are already under heavy sanctions, I don't see what is going to knock them around in this case. If anything, China is working to develop trade connections with states in Eurasia that largely have their own internal supply chains. It is true there is going to be an absolute shock to the entire system but it would hit the West and its East Asian allies far worse. We are already seeing this is action now to a lesser extent.
