why can’t we make an artillery minigun?

Question

So the concept started with the Gatling gun, the first rotating multi-barrel machine gun, and then was scaled up into the modern minigun. That was then scaled up to the 20mm Vulcan and 30mm Avenger autocannons.

Why can’t we scale it up even further with a multi-barrel rotating artillery cannon? One that shoots 3000 artillery rounds per minute and sends massive barrages of artillery?

Answer 1

Why? Whatever you hit with an artillery shell is going to be obliterated. You don’t need to hit it with 100 artillery shells

You’d prefer to spread your shots around to cover more area, not repeatedly hammer the same exact location
