If the VLS is as depicted in the CGIs and drawings, i.e. (mostly) flush with the deck, then definitely the 054B will not be using a full 9m UVLS, if it is even using the UVLS.

The H/AJK-16 will be more than 5 meters, I would think up to 5.5m if they can make that fit in the Sovremenny's missile magazine. A Shtil-1 missile is about 5.5 meters in length, and the magazine stores the missiles standing straight up. The HQ-16 is around just over 5 meters, so that's fine, the balance for the space would be for the gas transfer channels underneath. The U-VLS comes in 3.3m, 7 and 9 meters in length. You need the 9m to fire YJ-12 (assuming there is a VLS version) or YJ-18. HQ-9 missile is 6.8m, so the 7 meter version of U-VLS is good for launching that. But launching HQ-16 on U-VLS is a waste of space. 054B may not have the radar infrastructure to support the HQ-9 and one of the most annoying things about the HQ-9 vs HQ-16 is that both don't use the same frequency band for target illumination, unlike Standards and ESSM which can use the same illumination array.

I don't think H/AJK-16 needs improving, it seems to work great. The missiles themselves can be improved though, and most importantly, the radar suite.

I would think the reason for keeping slanted canisters for the anti-ship missiles amidships rather than using VLS is to save the space underneath.

In my opinion replacing the H/AJK-16 with the U-VLS on the 054B makes sense if there is (or will soon be) a new missile that can be quad packed "ESSM style" in the U-VLS and is good enough to replace the HQ-16 for medium range air defence. In that case even a 16 cell U-VLS would be better than the 32 cell H/AJK-16.
 
You want it, then you find a high res side shot of the 052D.

Quite the big guy, 21 meters est.

One thing is sure: this won't be fitted on a frigate :D
24 minutes ago posted just a heads up for those who wouldn't know about this presumably important development; I'm looking forward to read what various people will be saying

plus I have general type of questions like
Aug 26, 2017
what extent AND type of the damage do you expect to be inflicted upon a modern (=unarmored) warship by a single hit off a 32 OR 64 MJ railgun (presumably shooting around-5"-caliber metal rods)?

I now checked the kinetic energy of a hit by Mk 7 16" at its max. range had been

0.5*1225*514^2 (don't nitpick if I didn't read out at navweaps.com the striking speed correctly, if it's incorrectly quoted there, or anything)

which is about 162 MJ; I don't try to mix apples with oranges: the main point of hitting by a 16" shell of course wasn't its kinetic energy, but the main point was to deliver several tens of pounds of an explosive under the deck of an enemy ship, and blow up said explosive there (actually if the fuze wasn't set off, the damage made by a large-caliber shells wasn't much worse than just holes in the bottom, as it had been happening in the action of the Yamato against the Gambier Bay, an unarmored escort carrier)
(ignored or worse LOL)

EDIT
Feb 2, 2017
...


  • at the longest range: it's not easy for me to imagine shooting, at M7 or so,
    a metal rod almost 200 km up to the space :) so that it hits, at M5 or so,
    more than 400 km at some compound around which Ospreys then arrive, but it's
    an interesting idea;
  • at the shortest range, I don't know how a railgun is supposed to work in its CIWS role:
    would it shoot projectiles with a fragmentation warhead? or perhaps take advantage
    of its projectile's speed to slam it into an incoming missile?? (dubious considering evasive
    maneuvers but I won't delete it :) plus the advantage would be decisive only against subsonic missiles, I guess)
  • at the mid range (100 or so km), I'm completely at loss while thinking about anti-shipping fire:
    the railgun fire would need to be corrected, I guess by observing the splashes, by
    a drone with an EOTS or something, flying over the horizon, but if you're still with me,
    you can tell me why they wouldn't just shoot an AShM instead and did a mid-course
    correction since supposedly there would the drone in place, communicating??

In that case even a 16 cell U-VLS would be better than the 32 cell H/AJK-16.

Yes indeed they are planning on a new medium ranged SAM one that is going to be bigger than lets say a navalized PL-12. A good example would be something based on the 9M96E2 missile which I will use as a guidepost for a missile that is quad packable and still ranges up to 120km. Now an H/AJK-16 is no slouch in terms of size, an HQ-16 is not a small missile either, and there is likely room for quad packing missiles the size of a PL-12. Question is the length of the missile. The 9M96E2 is about 5.65m in length, and the H/AJK-16 has to be over 5 meters in length, as the HQ-16 is about 5 meters. The Shtil-1 is about 5.44 meters. That probably doesn't give much of a margin unless the H/AJK-16 is around 5.8 to 6 meters in length (5.8m if the H/AJK-16 is copying the shorter Mk. 41 Self Defense version). The actual 9M96E2 is cold launched though, which means additional length must be considered for the compressed gas canister. So its more likely the U-VLS with the 7 meter length would be a more comfortable fit with margins to spare.

However, until a Chinese equivalent to the 9M96E2 missile is introduced, the U-VLS is oversized for single HQ-16s, and while I have heard about the U-VLS claiming to be able to support HQ-16 (and other missiles like DK-10 and YJ-83 and so on) I have never seen test tired on one unless maybe the Type 055 or a special test ship that can demonstrate that using a digital beam forming X-band radar that can work for target illumination. The Type 052D can't test this since it lacks X-band target illumination, with its being on C-band. HQ-16 would certainly require its own concentric canister to work on a U-VLS, though that should not be a problem to develop one if one doesn't exist for it currently. As a final note, the 9M96E2 has active guidance and would spare the ship from having ship board illumination, and if the PLAN develops a similar equivalent using PL-12/PL-15 seeker, that would make things a lot simpler.

If the new frigate decides to use HQ-9, you will likely need to create a frigate version of the Type 346, maybe a single or dual panel, maybe each panel smaller, that spins around with a radome to cover it. That won't be unlike the "pineapple" radome we have been seeing in drawings and with an actual test mockup on Wuhan. Small fixed panel C-band illumination arrays would have to be set on the mast supporting the "mini-346" for HQ-9 target guidance. Not impossible to do, and the ship will keep the X-band Type 366 and 344 for ASM and gun fire control.

This thing is truly gigantic. If it is a railgun, then it represents a huge leapfrog over US efforts, since their railgun is still at a non-turreted experimental stage.

I was actually thinking if I didn't excited about what in fact would just for example a new type of crane LOL!

I translated one of the most well-known former PLAN officer's analysis, who has engaged in the building of PLAN warships for dozens years.
