At 6,000 tons, I doubt it. These ships are hopped-up frigates and will be used to provide air cover for the invasion convoy.
If this system is a revision of the Russian system, then maybe getting the radar was the reason for buying that old Russian carrier.
Invasion of Taiwan?
China doesn't have enough landing craft or amphibious carriers.
Any opposition, at all, by the US Navy, would have the Chinese calling off any invasion.
Some websites say that the phased array radars were jointly developed with a Ukranian research facility.There is little logic behind the fact that China got such systems from Russia for buying the Varyag,which the Chinese probably have no intention of making operational.If that was the case,they would have looked at SU-33s & AEW systems.
The interesting thing about these ships is the very limited numbers being built which makes it pretty unique from all other Chinese military procurements be it tanks,subs or transport aircraft.My own guess is that this radar system needs finetuning or that they are bidding their time to buy the various European systems around like the Italian EMPAR & French HERAKLES.
