VLS capacity at the destroyer-cruiser boundary

What is the practical VLS limit for a destroyer before it should be considered a cruiser?

A mixed battery around 64 strike and 64 defensive cells is near the conceptual upper end; more than roughly 100 strike-length cells pushes the design toward cruiser territory, though operational magazine needs are raising the threshold.

The boundary remains approximate, with 96-cell Burkes historically near the upper end and Type 055-sized batteries easier to defend as destroyer armament while at-sea reload remains difficult. VLS cells are the ship's usable missile magazine, so capacity determines how long it can remain on station before returning to port. Red Sea and nearby operations demonstrate why that matters: ships have expended defensive weapons and must leave the operating area to rearm, exposing both the mission and the ship to additional risk.
