Why does the VLS have to be for an existing missile? Having a larger VLS able to accommodate future missiles of larger size than legacy naval VLS would enable the development of specific navalized missiles.Perhaps they are looking at the DF-15 / DF-ZF missiles?
Does a hot-launch of a DF-15 missile generate too much heat and exhaust?
Or did they decide that it was just easier to design a VLS to accommodate the existing cold-launch DF-15 series?
