why can’t we make an artillery minigun?

1.15K viewsEngineeringOther

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?

The amount of heat would be insane. 

OTO Merla has a 76mm cannon for boats that can fire like two times per second. The breech and the chamber has a massive water cooling system. 

And this is for just a 76mm, we aren’t even talking about the heat from cannons of 155mm, 203mm, etc.
