A question. Do we know the type of 30mm gun the corvettes use? I think that those are installed amidships on the superstructure, not sure what freedom of movement they have though.

Many thanks for the prompt answers. I see it clearer now.

Here is what I was thinking. It might be the angle the pictures depict, but shouldn't the railing in the corresponding section the gun is installed be lower or removable (or have the turret installed higher?)

The last two pictures, combined with this one:

,depict that there is in fact a section in the superstructure railing that is lower-able/removable (you can see the hinges for that in the last two pictures in the post above). But the length of it pretty much restricts a lot the cone of fire against fast moving craft moving towards the ship (one of the prime scenarios that this type of guns are built to deal against).

I think it might be a small design flaw, given the fact that PLAN has expended the money to actually integrate the gun to the ships FCS and provide a full and automatic turret for it with extra electro-optic sensors.

Thoughts?

I had similar thought as you, but after I searched for my photo inventory, I found these. The barrel of the gun is higher than than the "railing", so there no problem with angle of coverage, unless the target is extremely close, say, within 100 to 200 metres. But then at this distance, an 5mm assault gun or a 12.76 mm heavy machine gun can take over.
