I think 054B is a disappointing upgrade. It makes no meaningful upgrade to the armamant from the looks of it. Same HQ-16 VLS with the same VLS count. If it uses slant launchers with old school subsonic anti-ship missiles then it will be the exact same armament package. The only saving grace will be if they Switch from 8 Yj-83 to 16 YJ-12 missiles. Then it could be considered a bit more uparmed in terms of land and anti-ship attack.
So far, I have been very disappointed with the 054B. Maybe all that tonnage went to endurance and that is its only saving grace.
Not the same old HHQ-16. Moderned HHQ-16F. Active guidance with 160km range. They likely outranged the old HHQ-9A (125km) on the 052C unless the 052C is now updated to the HHQ-9B (250km+).
YJ-12 isn't capable of land attack. YJ-83B is. The range of these is probably about 300km+.
Radar outfit is also superior to the 054A and is comparable to the large European frigates.
