Missile battleships are really large cruisers

What value do missile battleship and battlecruiser concepts offer?

They are essentially cruisers, but the underlying demand for a larger ship with much deeper VLS capacity is real.

Most missile battleship or battlecruiser concepts are cruisers shaped by mission rather than romantic terminology. Modern escorts have been built with insufficient vertical-launch depth, creating pressure for a larger hull that can carry more missiles. Calling frigates ASW cruisers and destroyers air-defense cruisers illustrates how function can be clearer than inherited labels. The genuine requirement is deeper magazines for sustained operations rather than revival of a capital-ship title for its own sake.
