Adaptive deck launchers exchange deck area for hull volume

What is the value of an adaptive deck launcher?

It adds missiles without penetrating the hull, but uses substantial deck area for a relatively small magazine.

An adaptive deck launcher is a classic naval-design compromise. It mounts missiles without penetrating the deck, which preserves internal spaces for other systems. That arrangement consumes more exposed deck area for each weapon than a dense VLS installation. It is useful when retrofit constraints make hull volume more valuable than clear weather-deck space.
