Ukraine still has a fighting force because it borders several NATO countries. Supplies are not interrupted by Russian’s weak VKS.
All four Japanese main islands are within 1500km from China northeast. PLAAF can use H-6 and J-16 to continuously to drop glide bombs all day long
How useful are they? Maybe you should ask the Indian Air Force.
How many of American ships are mission capable? Where are the potential areas for fleet battles?
China can only disrupt supplies to US forces via the pacific if they defeat US navy in the high seas outside first island chain, for that they need the big advantage in numbers in both Carrier and destroyer force. Chinese Air force cannot fly its planes that far in the 2nd island chain without getting spotted by ground based patriot missiles (US has a 1000 launchers) and Air force in the 1st island chain choke points. So, China has to completely destroy everything in the first island chain. Can they do that with just 2000 rocket force missiles?
All four Japanese main islands are within 1500km from China northeast. PLAAF can use H-6 and J-16 to continuously to drop glide bombs all day long
So? How many airbases on Japan islands can survived combined assaults from PLAAF and PLARF?
In order to use glide bombs China has to first defeat the vast 3000+ 4th+5th gen Air force US+Japan+other allies are likely to bring. As I mentioned before, China lacks the numbers to destroy all of the air fields in Japan. Moreover, Air fields can be repaired easily. The most important items are the planes, and they can be hidden just like Ukraine has done. Ukraine has withstood 3 years of Russian bombardment without losing that many planes on the ground. Finally, if those planes survive, they can fly and land using Highways.
So, ultimately this fight will be decided by vast air battles. Or Russia-Ukraine war style grinding battles where Planes do not go on the offensive without getting shot down. Air forces only operate in the margins. It could happen to US vs China battle.
People here underestimate the vast numbers needed to fight US+allies vs China battle. It will be ww3 and will need that level of numbers in terms of missiles being spent or planes getting shot down. Yes, China can defend its air space and prevent US from attaining air superiority and getting bombed. But China also lacks the numbers to go on the offensive and achieve air superiority with the number of planes and missiles it has. It will likely devolve into a slow grinding attritional battle.
That's why I keep saying, China's 1.5% GDP for defense is simply not a serious budget. Its a peace time hide and bide budget. They are only moving up in the tech ladder but not producing enough numbers to fight a serious battle and win.
