re: PLAN Type 052 Class Destroyer
I hope that a Chinese carrier battle group will visit Helsinki in the future.
But IMHO the ex-Varyag will more probably be escorted by Type 051Cs rather than the Type 052Cs, as it will probably be assigned to NSF.
Hmmm.... personally I think that the Varyag will be assigned to the South Sea Fleet - this fits it's training carrier role very well and all that training can take place in nearby and PLAAF/PLANAF covered waters - easy to reach, resupply and if necessary, rescue.
Also, holding training operations in the South China Sea will serve as a warning to the other claimants, without the stigma (small though it may be) of actually using a 'combatant' ship.
I don't believe that the PLAN will ever order another of the 051C class of AAW destroyers, they were the last of the 051 class and were both make work and test vessels for the SA-N-6 SAM systems ordered from Russia, (I judge them to be very inferior to the 052C class) and along with the Sov's they will be trotted out on various commemorative occasions and for showing the flag but in the end will be quietly retired.
What will be exciting for me will be the appearance of the successors to the 052C's and 054A's - that will signal the future of the PLAN's surface fleet.
