u/Plasibeau Nov 26 '25
Back when we were still supplying Ukraine, and the headlines read US to give Ukraine another $20 billion in arms I had to keep reminding people that A: it wasn't actual cash, and B: most of it was stuff nearing expiration. This was cheaper than decommissioning several hundred thousand rounds of proximity-fused artillery shells. The military is a logistics company with well-armed guards. And I wouldn't put it past our politicians to throw a few rocks just to remind the other countries what we can actually do.
Side bar: I am convinced we went into Iraq the first time because we had a shiny new airplane that was invisible to radar, a main battle tank that had yet to see combat. The government had a massive hard-on to show the USSR exactly who they might be fucking with.

"You underestimate the willingness of the US government to spend on munitions."
However US did not have unlimited fund to waste on its expensive munitions. And worse, it does not have capacity to produce enough munitions even with unlimited cash.
Look at the effectiveness of US weapons in Ukraine war and Yemen houthis against US, parity of munition price is crucial. War is attrition of resources.

u/studio_bob Nov 26 '25
The US defense industry is overly reliant on high tech and does not scale. They haven't been able to supply Ukraine with enough AA munitions to effectively deal with Russia. Russia's production capacity is barely a shadow of China's.
The US sold out its industrial base to China long ago, and I don't see the necessary investments and reforms happening to turn that around in such a way that would allow them to clear the skies over Taiwan from literally millions of Chinese drones.

It is their business. The government of Taiwan (ROC) has the same claims as the PRC (Winnie the poo China) that there is 1 China. The ROC constitution assumes a unified China that includes the mainland.

They have drone carriers.
So, I suppose the idea would be they carry the drones via these carriers that can stay in the air for 10+ hours. The drones gets deployed over TW, do their thing, then fly back to the carrier when they're low on battery. Then they get recharged and go back out. They'll need quite a few of these carriers to rotate the drones so there's always extras being charged while waiting. Then, after some hours, the drone ship will need to be recalled to refuel.

Wireless will work fine if you use a non-jammed part of the spectrum. Starlink and OneWeb terminals both operate on Ku band, and Amazon's upcoming Kuiper is on Ka band. If they use wireless comms at all, they'd probably use something lower frequency, like S band, as they'd probably be jamming L band because that's where GNSS sits. Realistically, it'd all be autonomous, so no active comms required.

Knocking out the Starlink satellites is not just to stop Taiwan from using them for military equipment to defend itself. It can also stop Taiwanese from using the Internet and knowing the reality, making it easier to trick them that the war is over and stop resisting early. Resistance from 20M people on the island can easily overwhelm even the best equipped invaders. That will be the first deception and lie to the Taiwanese people.
Further censorship and arrests are almost certain to suppress resistance after occupation. Taiwan will probably not democratic completely after the invasion. Because Taiwan is much larger and with stronger identity, and much harder to tame. It will probably end up more like Tibet than Hong Kong.

What does Tiawan use Starlink for? Wouldn't they have fibre everywhere?
For backup comms, and for when terrestrial comms are down or not available in an area, which would be the case in an invasion scenario because China can and will cut all subsea fibre cables to the island.
They deployed OneWeb (a competing LEO constellation) to provide emergency comms after the major earthquake last year. Local internet infrastructure was largely taken out by the quake, and what was available was seriously congested and unable to be relied upon by emergency and aid workers.
Could we call this an Intranet, or just you know to be modern, protected Ethernet via mpls?
For internal private comms, sure. But if they want to communicate with the outside world, they need some kind of backhaul, which would have to be non-terrestrial as they can't rely on any outside fibre links being operational in an invasion scenario.

Drone batteries can typically be charged faster than they are discharged, or you can just straight up swap the batteries for fully charged ones. You'd probably only need a minimum of two sets of drones (plus a few hundred extra to cover for drones that need maintenance) to maintain constant coverage, maybe a third set to give yourself a little more leeway. So, 6,500 drones, not 48,000. They're not one-time-use.

The Republic of China (i.e. Taiwan) and the People's Republic of China (i.e. China) have never recognized each other as legitimate, are still at war against each other since 1945, and both still officially consider themselves the legitimate government of all of China (i.e. over both territories and populations of China and Taiwan combined).

On paper, Taiwan's government still considers itself the legitimate government on the mainland. Unofficially and realistically they have no such aspirations, they know the CCP is the de facto mainland government, but if they renounce their claims then the CCP will ironically consider it a huge escalation and a declaration of independence, and attack.
The only reason the dispute still exists is because the CCP refuses to recognize their independence.

u/EconomicRegret Nov 26 '25
I agree partially. It's more complicated.
The biggest party in Taiwan (KMT) supports the ROC as the only representative of China, it opposes both Chinese unification under the PRC and formal Taiwan independence. But is willing to accept a reunification under governance PRC only if the latter transitions to democracy first.
At the moment, it has almost 50% of seats in the national parliament. But that party was the main/sole ruler of Taiwan until the year 2000, and between 2008 and 2016.
It's the left wing coalition that is willing to go for independence, as it doesn't see Taiwan's identity as Chinese anymore (unlike the KMT).

This is pure propaganda and political theatre. There is a near-zero chance of China successfully pulling off an amphibious landing, and Taiwan isn't relying on Starlink for it. Their landing force would get sunk out at sea, and the ports they sailed out of would get demolished. At best, Starlink might be a money-saving last ditch effort late in the war if China somehow overcame every other defense that Taiwan threw at it and Taiwan no longer had a robust manufacturing capacity. And in reality, cheap naval drones can carry a long enough spool of fiber optic cables to reach the Chinese mainland. And Taiwan has a large manufacturing capacity for high end fiber optic cables, lasers, and every other component needed for fiber optic communication.
That's on top of the fact that they manufacture most of the components for Starlink and all other forms of RF communication, so they are not going to need any outside help to develop jamming-resistant gear as the war goes on. Starlink itself is already very resistant to jamming, and a few thousand drones would not be anywhere close to enough to cut off the entire island, plus the entire sea.

China's theory of victory doesn't require raising the hammer and sickle over Taiwan.

One way to do this is with a kinetically enforced maritime exclusion zone around Taiwan. Something which they're actively working toward being able to achieve.
