Interesting...
This one is new photo. The ones I've seen has the section right in front of the bridge blocked by that blue crane.
So, from what we can observe thus far, this warship is likely a new class of corvette.
Armaments of the warship include:
1. Either 57mm or 76mm gun, housed in LO turret;
2. Some kind of VLS (one 8-cell module maybe?); and
3. HHQ-10.
That large-size helicopter landing pad relative to the size of the warship itself probably means that it can operate not just Z-9, but probably Z-20 as well. Though, until the warship can be seen from the rear, I don't think there will be a helicopter hangar onboard.
