I'm not an engineer but here is what my "gut feeling" tells me. Aside from the dimensions of a ship, here are some other variables that need to be included if you want to add more missiles or bigger missiles / bigger VLS cells.Do we know if there has been any information on the Chinese naval research institutes developing large-diameter VLS cells (LVLS) for use on major PLAN surface combatants in the future?
So what do you guys think? Feel free to comment and/or rectify.
1) weight and balance - a ship's weight distribution must be split 50 / 50 in the front and back or else the ship will not be level. If you're going to carry larger missiles (presumably in the front), this weight must be balanced.
2) structural integrity - when a missile is fired it will produce stress and vibrations on the ship. Larger missile == more stress
3) survivability - if your ship takes a hit from an enemy missile, is this going to trigger the explosives and missiles on board? I hope not.....or else! If you're carrying larger / more missiles this issue needs to be addressed.
Here's my 2 cents:
I believe the PLA-navy will put larger missiles / larger VLS cells on some of their ships, the Type 055 will be a good candidate.
