If they do put it on, I guess PLAN want an enhanced ASuW version with independent OTH SSM targeting capability.
see the evolution of Tarantul II
to Tarantul III
the most recently version Molniya class is in service in large number with the Vietnamese navy, also have a OTH SSM targeting ability with MR 352 Positiv-E radar (without the passive component of Mineral ME/Bandstand).
You're reviving my feeling that the Type 056 is underarmed, back to thinking 15x FL3000 and even 8x YJ-83 being necessary.
Comparing a new build 056 (056A?) and an existing modified 056 (as compared to the original 056 with bare funnels etc.):
1) There is now either a taller solid railing atop the bridge or there is added internal ceiling height, or both.
2) The pedestal at the foot of the mast now protrudes more onto the roof of the bridge.
3) There is now an additional spherical sensor on the port side of the aft superstructure.
