KunLunShan? A snow capped mountain surrounded by a desert in the far West? That's... contradicting. Entered service already?

to the best of my knowledge, normally giving the ship a name (and announcing it) is equivalent of commissioning the ship in PLAN, but I could be wrong.

Re: Type 071 LPD

two Phalanx CIWS compared to four AK-630 at 071 C ... didn't you think thats in result a win to 071 C class?

The 071 can only handle maximum 2 targets, if both the front and back FCRs can be used to provide fire-control direction for the AK630. So that puts it at most equivalent to the INS Jalashva in terms of self defense hard kill capability. Phalanx is self contained and has close loop engagement control, while the AK630 might suffer from parallax errors due to its off mount FCR. So I'd put the advantage with the Phalanx.

The JNRG system allows targeting information from type 347G radar, the new naval gun FCR, SR-64 + IRST (surprisingly, I don't see a E/O tracker) and then use both AK-630 and AK-176 against the targets. If two targets from same direction are coming and one gets eliminated fast enough, you can go after the next one. Not limited to only 2 targets.

Re: Type 071 LPD

Yes, I was not very accurate there. It should be '2 targets simultaneously'. But that same argument applies to the Phalanx, so no change in conclusion.

Re: Type 071 LPD

AK-630's another big shortcomming is that its not able to fire and move simultaniously. It can fire to one direction, stop firing, traverse the mount and fire to another direction.
AK-630 is not a CIWS in the sense that of those western ones like Phalanx or Goalkeeper. It dates almoust two decades before Phalanx and it is in functional concept more close to other radar guided automatic gun systems (Like the chinese Dardo derivate, type 76A) than pure CIWS althoug its mented to fullfill the same role. First true CIWS system from soviets was the Kortik/Kashtan system which boosted up the standarts of CIWS by adding missiles to the system.

China also has a fullborn domestic CIWS system, the Type 730 which is fully comparable in terms of concept to the Phalanx but suprisingly it didn't fit this ship with it. Its hard to find some operational reason for this and only thing that comes to my mind is some sort of limit in the availability of the system. Perhaps there is limits in the ammount and rate of producing the system that the availble CIWS were assigned to higher importance level warships, 051C and 054As (which were constructed roughly at the same time as 071) and the landing ship had to seddle for the older generation system.

Re: Type 071 LPD

but then again the first 071 may be just a test platform for the concept and basic design, just like 054, using AK630, and HQ7, but 054A used 730 and VLS instead, so it is likely for the subsequent 071s to be armed with 730s

Cost may be a reason. The Tye 730 isn't likely to be cheap.

I'd guess it's because it took longer to design, the CIWS choice was probably frozen before the Type-730 was 'proven'. Or the designer weren't familiar with it. Just guesses.

There really isen't much to be gained in testing purpose to have different weaponsystem fitted for the prototype and production version. It means that a) you cannot test that particular weaponsystems operationality on the prototype and you need to keep on testing and trialing with the production versions as well and b) you need to make additional design work inside the shipclass if the weaponsystems changes (exspecially in this case where modular approach cannot be used)

I think its more to cost/availability and production capacity of the actual weaponsystem than to the individual ships statusess. The two 054 had the AK-630s for exactly the same reason as well as the different SAM compared to the later version, the weaponsystems status wasen't ready for the ships, not the ships status.
