nice
so Batch 3 is using which engine ?
That's for the moment the Mio.$% question ... so far we've only seen it uses a different - aka green - anti-corrosion primer, but this could bean it is simply a different one or it could mean it covers a different surface material.
Otherwise we know nothing: if it uses WS-10 engines, if it has a new - maybe AESA - radar, if it is catapult capable ...
I think we simply have to wait for more images.
