China can't win a conventional war with US at this point. I know this is an unpopular opinion here but that's the truth.
A significant portion of PLAN's surface fleet would be decimated by mostly SSNs if they venture out past the 1st IC.
I believe that PLAN's current ASW capabilities will have a very hard time detecting and sinking the Virginia class boats. The fear of being sunk alone will keep most of PLAN assets very close to shore thereby nullifying a significant portion of the naval capabilities.
CV17 and 18 will be a non issue for similar reasons.
JMSDF assets are nothing to laugh at either. Presumably in an all out war, JMSDF and ROK would be actively engaged together with NATO forces and will keep the northern fleet busy.
PLAAF can only effectively fight out to the first IC. With airbases taken out, their combat effectiveness would be significantly reduced.
They also lack a robust AWACS and ELINT coverage during wartime compared to US and NATO forces.
To be fair, I do see devastation of naval and air facilities in Japan, ROK, Phillipines, likely Guam and if everything goes right for Chinese planners, perhaps even Pearl Harbor may be hit hard.
However mainland US will be relatively unscathed while the Chinese mainland will be hit hard. Certainly any military targets and factories etc. will be taken out together with civilian infrastructure like power grids.
In a wartime economy I believe the US can significantly churned out F35s and B21s at a decent rate.
US factories will also not faced destruction unlike Chinese factories. Even 80 yrs later, the contiguos US is still relatively safe from harm thanks to the Pacific ocean in this case.
Geography significantly favors the US. That is a cold hard fact. China is also surrounded by less than friendly neighbors. Two of which have a decently powerful navy and air force.
These two immutable factors alone makes it highly unlikely that it can win an all out toe 2 toe fight.
One thing is certain however.
In an all out war with the US, Asians of all different nationalities; Chinese, Japanese, Koreans, Filipinos. Taiwanese etc.... will suffer horrendous casualty rate.
For China to win against the US in a conventional war given the current known constraints such as unfavorable geography, lack of FOBs etc.. it has to significantly improve on things like ASW, including many dozens of new gen SSNs that can at least match current US subs, massive mid air refueling capacity, at least 8 CSGs, numerically more 5th gen fighters and an order of magnitude more super long range hypersonic missiles or AShm capabilities.
You don't understand that a failed American invasion will lead to an island hopping campaign that US is powerless to stop due to lack of industrial capability.
China has no need to engage the USN in decisive battle in the deep pacific, and that is the only scenario where US could win.
PLA is untouchable within the FIC. If you don't know geography, the FIC includes SK and Philippines. The former has NK right next to it and the latter has a very poor military.
Which means as war starts, US cannot properly reinforce these areas due to heavy extended Chinese defenses, so if these countries engage in aggression against China, the PLA will put them under occupation.
Then, using new staging bases such as Busan, China will tighten the noose even more on Japan and Ryukyu, which is already facing bombing and soft blockade from day 1.
US is powerless against any part of China except Taiwan. The reason for this powerlessness is distance and lack of bombers. America has less bombers than even the Russian Federation, and coastal Chinese cities are far more defended and lie even further away relative to American bases than cities in western Ukraine do relative to Russia. Also, China unlike Ukraine will do round the clock strikes on those limited airbases.
But in wartime, it wouldn't be close to US cities like Liaoning doing most of the production, it would be the likes of Chongqing and Chengdu, which have so much strategic depth they may as well be on another planet as far as US is concerned.
If a Virginia meets a Yuan, the Virginia will be at a detection disadvantage. That said, a Virginia can always outrun a Yuan, so it should never be an issue. Except in this case, US is the one attacking, so they need to venture into advanced SSK infested waters, or keep the Virginias useless in the furthest reaches of the second island chain. Besides that, China also has the most or possible 2nd most well developed surface ASW in the world.
Between these 2 factors, the US undersea fleet is a threat only where SSKs and ASW cannot reach, and as outlined above, China will follow an island hopping campaign, successively ramping up war production as they go.
Your post is either extreme ignorance of how wars work or an exercise in glorious American nationalist copium.
Consider in ww2, the USSR never had the means to truly "reach" core German territory during the most decisive battles in the war. Every such engagement was fought inside German RKs. By the time USSR forces threatened the German homeland, the war was a foregone conclusion. Likewise, if America loses Philippines, SK, Ryukyu and Japan, it will be far far too late to stop a total defeat.
