Another factor I forgot to mention about the PLAN's expansion, is that the GDP continues to grow. At some point it will overtake the US GDP, and if it maintains a 2-3% of GDP on defense expenditures, even exceed that of the US itself. The PLAN as we have seen recently, has a growing share of the budget increases as well. That means what its spending now, is merely the tip of the iceberg when compared to the next decade. Even by 2030 to 2040, there is still cheap labor fuel and combined with increases of productivity per worker thanks to automation, plus a vast middle class that continues to grow, we can still see fervent economic growth, that is going to sync with future increases in defense and naval spending. What we see now from the PLAN may still be in its early stage of growth, and we have seen nothing yet.
I see the PLAN's role shifting and evolving. Contention of Taiwan, and contested islands in the ECS and SCS, will give way to priority to the PLAN as a protector of this economic growth, by projecting power and protecting trade routes of it's economic sphere (OBOR, Shanghai Bloc, etc,.) The PLAN and the Party will give way more and more to Mahanian navalism, seeking to achieve symmetric peer to peer equality, and away from the A2AD strategies experts once thought it would pursue at the turn of the century.
Compared to ORBATs, I am far more interested how upgrades can be done. Stealthy things like the F-35 and LRASM introduced to the Asian sphere, are disruptive threats that need to be countered. I am not sure if many of the ships at the way they are, are survivable in a hot conflict in the next decade or two. In order to retain as much 054x and 052x, which will become older designs, they would have to be upgraded in order to further improve their ability to detect and target. But the upgrades need to be done in a way that isn't complex and require the least structural or "deep" changes to the ship.
Type 052C ---
Replace Type 346 panels to the Type 346B standard using GaN.
Type 730s changed to one Type 1130 and one HQ-10 24 cell launcher.
YJ-62 missiles retired, replaced by YJ-12.
VLS retained. Earlier version of HQ-9 retired and replaced by later versions with active guidance. I may eliminate the C band array for target illumination for more S-band elements for greater search and tracking, and I suspect is the version used for the carriers.
Back end, transmitter and receiver upgrades to the Type 364, 344, 366 and 517 radars. Or conversion of Type 344 and 366 radars to a combined AESA X-band unit and Type 364 to a rotating scan digital phase array C-band unit, preferably AESA.
Type 054A ---
Back end, transmitter and receiver upgrades to the Type 364, 344, 366 and 382 radars. Or conversion of Type 344 and 366 radars to a combined AESA X-band unit, Type 364 replaced with a rotating scan AESA C band unit, and Type 382 to an S-band AESA, using two rotating Type 346 panels.
H/AJK-16 VLS retained. HQ-16 retired, replaced by a new version of HQ-16 with active guidance, and quad pack of DK-10 also with active guidance.
YJ-83s replaced by either four YJ-12s or eight Yu-10s in an ASW configuration.
MR-90 radars used for target illumination replaced by four X-band fire control radars, with active elements. The locations of the MR90s appear to give the best radar coverage around the ship to deal with a multiple axis saturation attack. Instead of target illumination, these radars work mainly on track while scan modes to track multiple objects and provide high quality tracks on targets all around the ship, which the data is fed via data link to the missiles. The basis for the arrays can be those used for the J-11D such as shown below.
