The launcher is only available with single cell (for really tight spaces), 8 cell, 18 cell (carrier version like on Liaoning), 24 cell (destroyer version like on Type 052D).
The launcher is manually reloadable at sea though, which is something you can't do with a VLS. The choice of using an 8 cell instead of an 18 or 24 cell might be due to the height of the other two launchers that makes them difficult to reload the upper cells.
I was looking for a way how the crew would reach the deck so they could reload the cells, and it turns out there are doors at the back of the funnels. I also thought that the type would be better if it has a hanger to store and maintain the helo but it looks like there are two hangers for UAVs instead.
