VLS avoids the cycling required by an arm launcher because its missiles are already in position to fire. That readiness is valuable against a mass missile or drone attack. The same cells hold the available ammunition, with no separate stock of reloads aboard in this comparison. The discarded crane arrangements illustrate the difficulty of replenishing them at sea.

Ready VLS rounds allow rapid launches, but the launch cells are also the ship's available magazine.
