This is describing the vast difficulty in targeting Chinese military assets with missiles, without any interception capability from the SAMs and discounting the entire PLAN and PLARF... Just looking at missile stockpiles vs air defense and targets.
I most certainly am not discounting the entire PLAN and PLARF.
This entire chain of the thread has been describing a war of attrition -- i.e.: a war that takes many months -- if not years -- to be fought.
With the given forces that each side has at present, and their pre-conflict positioning, in a war of attrition I fully expect the US to be capable of significantly degrading Chinese military production facilities, the longer that such a conflict drags out.
Even for a Taiwan scenario, the PLARF has stockpiled 2000+ SRBMs and N cruise missiles to disable Taiwanese air defense long enough for a follow up strike with PGMs and hit critical civil infrastructure for a region FAR smaller than all of China, and this is for a scenario that doesn't require a naval battle (as Taiwan's navy is negligible vs the PLAN), refueling, worrying about your own bases, etc.
A Taiwan contingency that the PLA plans for, versus a generalized high intensity westpac war of attrition, are so different in terms of geographical force disposition, opposing force capabilities, timescale, and respective objectives, that a comparison is virtually useless.
When you take into account the need for a naval battle and tankers to even get to the point where missile strikes against ground targets inside China are possible there would already be significant attrition of strike assets... If they win the naval battle without horrible losses at all.
Conclusion: they don't attempt a war of attrition because the math doesn't work out in their favor.
What is more likely is that China will be capable of incurring significant casualties to US air and naval forces in the region during a conflict -- but at great cost to PLA's own air and naval forces in the region.
However, the much greater quantity of global US forces means the US will be capable of reinforcing their air and naval forces in the region in relatively short order (multiple months) while also conducting targeted long range strikes with certain assets that China is unable to properly defend against at that point (SSNs, SSGNs, CONTUS based US bombers) due to the significant losses of its air and naval forces have incurred. This will result in a initial small scale targeted strikes of key production facilities that are vital subsystems for important PLA weapons systems (subsystems involved in weapons such as stealth fighters, long range missile systems, destroyers). The scale will be small initially, but gradually enlarge over time.
Such actions will start off by delaying their production/delivery, then reducing their production rate/delivery, then become wholly unable to be completed in general as time passes.
Over the course of a year, and then two years, and then three years, China will eventually be unable to sustain its losses while the US is capable of replacing its losses, until a tipping point is reached and a general collapse of China's capability to sustain a meaningful air and naval presence and losing the capability to build long range strike missiles in general, at which point it becomes a matter of the US choosing to gradually mop up the remaining ground based air defenses and short range air and naval assets China has remaining.
For China to be capable of making a war of attrition at minimum "equal" between China and the US, China will need to possess the air, naval and missile capability that are able to soundly defeat initial US forces in the western pacific in an initial conflict phase while suffering minimal losses of their own.
The remaining PLA forces after the initial conflict phase would need to be at least equal to the rest of the global forces that the US has remaining that they are able to redeploy to the western pacific in a follow on conflict phase.
Or, putting it more simply, I see a war of attrition mostly as having 2 phases.
Phase 1 conflict:
Westpac location
Duration, occurring over multiple weeks/a few months
Forces at play: Initial Overall PLA Forces vs 50-60% of Global US Forces (assuming 50-60% of the total US military force is redeployed to fight China)
Phase 2 conflict:
Likely occurring multiple months after Phase 1 conflict
Duration, unknown
Westpac/central pacific location
Forces at play: Remaining PLA forces (after Phase 1 conflict) vs Remaining US Global Forces (after Phase 1 conflict, which assumes that the entirety of the US's remaining military force in the entire world has been redeployed to fight China)
The war of attrition will come into play in Phase 2.
In Phase 2, China would do poorly in a war of attrition if the "Remaining PLA Forces" is markedly inferior to the "Remaining US Global Forces".
However, in Phase 2, a war of attrition could be about equal for China and the US if "Remaining PLA Forces" has approximate parity with "Remaining US Global Forces".
That means the big question is what sort of capabilities and overall mass does the PLA need in the "Initial Overall PLA Forces" in Phase 1, to allow their "Remaining PLA Forces" in Phase 2 to achieve rough parity with "Remaining US Global Forces".
But whatever the "Initial Overall PLA Forces" would specifically look like, I think right now the PLA most certainly is not there.
