re: PLAN Type 052 Class Destroyer
In the new universal VLS hot launch will be CCL canisters, cold launch will be just plain ole cold self contained canisters like HQ9. We don't even know whether this VLS will be on the 052D. Also why would you want to quad pack HQ10 in there? The current conventional launch is much better.
The only way to cold launch using CCL is if the ejection system is also completely enclosed inside the module. This means additional space requirements, meaning if the cold launch CCL cell is the same size as surrounding hot launch cells, by necessity it would have to use a smaller missile, possibly a much smaller missile. If the number "0.85m/cell" is correct, then I don't see how they would be able to quad-pack HQ-16's in there since that number also represents the venting system. I'm not even sure they could quad-pack HQ-10's in there. And let's not even talk about the guidance radars that would be required for both of these missiles (which we so far don't even know exists on the 052D), even the HQ-10 since it would be launching blind (vertically) and would not be able to acquire diddly squat without external cueing.
