I see your point , then maybe the main problem is the radar and the fire control .
But is still follows the logic I stated , to solve the problem of low hit rate , the Russians went with higher RPM , the Chinese replaced the radar .

Newer Russian ships dispensed with the old MR123 with a new fire control radar that looks like a phase array called Puma.

Type 344 and 347 fire control radars were derived from European techs, possibly Thompson or Selex, and they both resemble European naval fire control radars like the ubiquitous Thales STIR. They were introduced with the Type 052 in its original form, so these fire control systems predate the second Russian coming of arms technologies.

The first two Sovremennies came years later and the PLAN is in the perfect position to pick the best and choice technologies possible from a pallet of both European and Russian techs. It was clear they were impressed with several technologies introduced by the Sovremenny. From this ship, they copied the Fregat MAE search radar, the Mineral ME OTH active passive radar and datalink system, the Shtil missile system and target illuminator, the AK-130 gun and the AK-630 CIWS. The AK-176 gun was also introduced to the PLAN by other means and that too was copied.

But what they choose not to copy and adopt were the MR123 Bass Tilt and MR184 Kite Screech fire control radars for the guns. Instead the PLAN continued to use both earlier Type 344 and 347 fire control radars. Is this a hidden testament that the Russian FCRs did not meet PLAN'S satisfaction?

IMO, PLAN won't bother copying the AK-630 if it was bad. But the fact they omitted the Bass Tilt FCR in favor of the Type 347G or 349 FCR to mate with the AK-630 and H/PJ-13 is to my mind, is rather telling. Bear in mind that the 730/1130 both still use the older 347G FCR with the rice hat cone, but it is the PLAN service AK-630 and H/PJ-13 that is working with the newer Type 349 radar set that has a flattened cone, which could be a more advanced set over the 347G.

It appears the dredging work on the new large basin at Jiangnan shipyard is nearing completion, if not finished already.

I don't agree. LSTs are large ships and the force they are supposed to carry is extremely valuable and politically important. So I don't think a nation should go light in an LSTs defense. SHORAD is cheap, compact, and can save lives. I would have 2 x short-range air defense systems on board. The HQ-10 is already available and is fit for the job. Soft kill measures need to exist too.

130 mm gun is more debatable since modern targeting and networking can enable other ships to do that job. But an LST would undoubtedly benefit from being able to support the landing. It can be offloaded to another vessel but the capability needs to exist. 76 mm is OK too and it can be used as a CIWS too. Just like the HQ-10, a modern naval gun is compact and light for an LST and its price is nothing compared to what the ship is supposed to carry.

For example:

Other than these the 074A already has good helicopter capability and a modern structure with a stern ramp.

LSTs are not large ships. They're only up to 5000 tons and are actually really inexpensive.

The Teluk Bintuni LSTs built by Indonesia are roughly comparable to the Type-072 LSTs, so the Type-072 LST might only cost $13 Million.

Also remember that most of the time, LSTs will be transporting trucks and supplies. I'd be surprised if this sort of cargo would be worth more than $3 Million in total.

Yes, SHORAD systems are comparatively cheap, but even a HQ-10 would be comparable to a TOR system ($25 Million) which is a land-based Kashtan CIWS/SHORAD. So such an air defence system would be significantly more expensive than the LST plus its typical cargo.

And I would expect the area where LSTs are operating to be flooded with air defence destroyers and frigates, whose job would be to provide air defence.

We had a short discussion on LSTs/LPDs/LHDs in the post below.

A little correction. Land based Kashtan CIWS is Pantsir SAM, not Tor.

Tor is already land based, its sea based version is called Kinzhal aka SA-N-9 Gauntlet.

Here's more details about the 2012 incident during the joint exercise with AK-630. The drone involved was a

and the Russian ship taking a shot was Varyag of the Russian Pacific Fleet, another Slava class. She opened fire with four AK-630 and didn't score any hits on the first pass. Afterwards the Russians explained that their AK-630 was designed to defend against missiles and not against such a slow target.

That explanation is what makes me a bit nervous about any PLAN ships armed with AK-630 or derived CIWS.

Ah, the dune school of naval combat "Slow missile penetrates the CIWS"

Lots of Frigates on Chinese side, meaning a strong green-water navy. The blue water elements growing in size in time while the US Navy stays mostly on blue water power projection.
