A containerized VLS is more than a missile box

Could a modern point-defence vertical launch system be containerized, and would a four-cell package provide enough defence?

The system is possible, but launchers, control equipment, missile dimensions, and shallow magazine capacity make a simple four-cell container only a limited defensive measure.

The launcher is only one part of the weapon system. Control equipment may need its own container, while the missile dimensions make a simple standard-container arrangement difficult and may require a pop-up launcher. A later four-cell proposal improves the packaging problem without providing much magazine depth. Quad-packing smaller weapons could yield sixteen missiles, but that remains a limited defence rather than a robust escort substitute. The answer therefore treats containerization as a systems and capacity problem rather than a matter of placing missile tubes inside a box.
