Its settled then, the new build 054A's have the Type 1130 CIWS mounted.

But something's baffling me.

This version (unlike the Type 730 or the Type 1130's on Liaoning) doesn't have the radar or the electro-optical system mounted on it.

That means it does NOT operate autonomously and will have to rely on external sensors and computing power for it's fire control.

It cannot search and track targets independently of those sensors and computers.

From an autonomous (virtually independent) CIWS they opted for one that relies on external sensors and computing power.

The question is WHY?

Or am I jumping the gun and those sensors will be mounted later on?

That seems to be a rather complicated job for the shipbuilder.

I'm guessing it will be mounted later. The other thing to consider is that speed of transmission is so fast now that it really doesn't matter if the processing is done externally and then sent to the gun for engagements. In fact, I think it would be done regardless. The main loss here would the additional set of sensors.

Cannot remember seeing this here on SD, but I believe it was from 2013 and a Sino-Vietnamese South China Sea standoff.

Amazing picture of one of Vietnam's new Gephard class frigates in a near pass with a PLAN Type 054A frigate.

This photo was taken in June 2013 during a joint naval drill of Vietnamese Corvettes HQ011 and HQ012 and PLAN off the PLAN base in Zhanjiang.

The sensors have been mounted per the latest photo:

A nice shot of two 054As alongside an 056 (HP?)

The first two pictures show the two 054As, with cut outs at the rear for VDS. I think one of them is the recently launched one with Type 1130 that we've been following. The other one looks like it didn't have a hole for VDS originally but it was cut out? I could be remembering incorrectly though, I gave up on following progress for all 054As. Either way, it looks like PLAN have found a VDS they are happy with to add fleet wide to complement their TAS. TAS, VDS, and bow sonar looks like it will be standard for all new destroyers, frigates, and potentially corvettes.

Compare with the VDS hole for 056, number 593, seems to show some differences in design (possibly due to difference in volume of ship available in 056 and 054A, resulting in different deployment arm designs for the same type of sensor?)

The 054A seems to have an external hatch to cover when not in use? Maybe that design is a factor for a different arm?

The 056 ASW version has this giant opening in the back now. Given its smaller stature and primary operational area in the ECS/SCS, the RCS negative with this opening might not be as big of a deal compared to a larger ship on the open seas.

Best weapon for hunting submarines is bow mounted sonar, a towed sonar and most formidable weapon a anti submarine helicopter

Yes variable depth sonar is also good

But PLAN needs plenty of experience in submarine hunting it's a fine fine art to master

I would like to see PLAN excercise more with its submarine and surface fleets in deep water far from home shores

Do a cat and mouse training mission between the surface fleet and the sub surface fleet to sharpen the skills of both party's

Submarine commander needs to know the terrain and under water features where they can hide and take cover

Surface fleet need to know what they are looking for sometimes even a large cluster of fish in the oceans have signals that can make it look like there is a submarine down there that is not a uncommon occurrence
