Why? Seems like a bunch of missiles, ground to ground, or whatever would be a lot cheaper in the long run wouldn’t it and a lot easier to move around and protect.
Missiles cost a lot more than artillery rounds (usually).
Only if money is no object and you like burning it.
A Tomahawk missile costs about $832,000.

An Excalibur GPS artillery round costs about $60,000.

Sometimes a missile is the only way to go but, when it's not, artillery is the way to go.
