Why interwar naval rockets needed more than propulsion

What if interwar navies pushed rocket development as a workaround to treaty gun-size limits?

Some progress was possible, but guidance, targeting, launch integration, and supporting sciences would be more limiting than the rocket itself.

A large rocket is only one part of a useful naval weapon: it also needs control, spotting, target acquisition, and a practical ship or aircraft launcher. Radio-control experience from target drones offered a path, but beyond-visual-range guidance would still demand aircraft and extensive development.
