Re: DDG 052C Thread
Well thats four small individual cold launch models isn't it? Might work on a S300 launcher, but I seriously doubt if all four launchers would fit in the same space as a regular S300 canister. Even if you do make them small enough so that four can fit in the module, your missiles are going to be smaller than hot launch quad packed missiles of the same parent cell dimensions.
Such a cold launch configuration will also cause you problems when you are replenishing missiles, especially if you didn't shoot all four missiles from a quad packed cell.

Re: DDG 052C Thread
No, it isn't. Look at the base of the quad launcher. One launcher, four tubes.
I don't know what you're talking about. Again, look at the base of the quad 9M96E2 launcher tube. It is exactly the same diameter as the S-300 tubes sitting right next to it.
As I already said, the quadruple launcher can already fit into the same spot as an S-300 launcher. Not only that, the 9M96E2 missile has no problems reaching out to 120km vs the ESSM's 60km, despite your concern for their living conditions.
This is almost a total non-issue. The quad-pack is the same size as an S-300/HQ-9 container, so even if 1 out of 4 rounds was expended before you reload, you can just reload a fresh container that contains all 4 rounds. The container with 3 rounds left can be reloaded separately by the supplying ship or at pierside.

Consider the USN uses cold launch for SSBN's, so there is a definite engineering advantage to hot launch for surface ships.

Re: DDG 052C Thread
You can't compare surface launches to underwater launches. It's not even clear to me that underwater hot launches are possible in the first place. But even saying there is a "definite engineering advantage" to hot launch doesn't say which advantage is being preferenced. As far as I can tell, space efficiency is the only advantage that hot launch has, and as I said before, this seems to trump any advantages cold launch has to offer. I used to think that cold launchers have single point failures in the form of the gas ejection system, but TBH hot launchers also have a single point failure in its exhaust system.

whoa! didn't know my question would spark such a lively debate BUT it's great.. afterall this is what forums such as this are about.. to talk and discuss rational and technical merits of weapon systems and platforms employed by the PLAN or other navies etc.

Re: DDG 052C Thread
Square cells are not any more space efficient than round cells. In a square box, the missile is still round, so there is wasted space at the corners. The diameter of a round tube will be the same as the diameter of a square tube, thus you can put the same number in a block. China just has a strange circular way of arranging them, not sure why they design it that way.
Re: DDG 052C Thread
Each set of 6 rounds is arranged in a circle because the central part is a gas ejection system which is responsible for launching the missiles in the 6 tubes arranged around it.
