Second the UK's armed forces are a global joke and giving even a few fast jets to the hohols means they'll be stripping their own defences. Johnson has come out and outright said they should do this, leave the country defenceless so they can earn ass pats from the Burgers. Amazing.
It'd have made more sense to send all their tanks. the UK is a fucking island, and I guess they forgot the lesson they learned in the Blitz that planes can fly over water.
Surface ships are forced to stay out of range of Chinese weapons, meaning they play more of a supporting role out in the pacific. Submarines are the only thing that can operate near Taiwan. Sub operations are made very difficult if the Chinese are able to set up minefields.
The new big thing for the PLAN in ASW is detailed oceanography data for Magnetic anomaly detectors (MAD) and gradiometer anomaly detectors (GAD). The counter for the former is tedious or expensive to defend against (degaussing, or in the case of the Swedish have magnets shipwide to offset the magnetic field), the later is not counter able but requires extremely precise measurements of the background levels.
I will disagree with the CSIS wargame though. Few things to consider:
1)Any shooting war with China and the US the Koreas' become a shitshow because Golden fatty the third doesn't listen to anyone. I also don't think they're taking in consideration the strategic petroleum reserves of either country.
2) Mainland China is more constrained by resources The US has 4-12 months in the strategic petroleum reserve, China has 3 days-3 weeks. In addition, the majority of China's oil (like 89% back in 2010) comes through the straight of Malacca and is easily interdicted (This is changing with Russians new pipelines a bit). On the reverse side, the US has niggers, additional obligations, (NATO) and a declining industrial base (like the UK in the interwar era).
3) PLA ammo storage is around 200 miles inland (outside of most weapon ranges at the time). Part of the reason for the severe lockdown right after Russia-Ukraine kicked off was that China would need around 200,000 drivers to be able to move ammo effectively 24/7 and the Chinese though the RFAF was gonna rofl stomp Ukraine.
Now, unless something drastic happens (eg: 5th fleet and jarheads try to land at Sevastopol and gets vaporized via a nuke), PLA has exactly four possibilities of winning:
1) Neutralize the USAF and USN aircraft effectively in Taiwan and prevent resupply by interdicting all shipments from the east (Maybe)
2) Knock out the 7th and 3rd fleet (very unlikely)
3) Knock out enough of the USN to make it politically unacceptable to the US populace (Most likely)
4) Some sort of hail marry like Sealion (impossible without significant defections from ROC)
The PLA went for a mixture of 1 and 3. You can tell from the J-20 original design, it is designed to "push out" the USN CVGs by launching ASMs and then running away.
The backbone of the the PLAAF is J-10 (An indigenous design with some "reverse engineering" from Pakistan's F-16s) and J-11 (A "better" copy of the SU-27).
I highly suspect that any fight between the US and mainland China will be the first war where guided missiles are slung around en-masse. It'll be a question of who's got better IADS, semiconductor production (for missile guidance) and if the PLAF can consistently strike ships with the J-20. China either goes big or goes home with a lack of petroleum reserves, there's no "long lasting fight in which the USN eventually wins".
If the US sends fighter jets to Ukraine, China would be really fucking happy to see the Russians shoot them down. Kinda like how the US wants Ukraine to fight to the last holhol.
