Making a to-scale mockup and then targeting it with ballistic missiles would help them understand the actual accuracy of their missiles under ideal conditions.

Making a to-scale mockup and then targeting it with ballistic missiles would help them understand the actual accuracy of their missiles under ideal conditions. Of course, hitting a moving carrier with active defenses would be much harder, but if you can't even hit a static carrier under ideal circumstances then you have no chance of hitting a mobile one.
