why can’t we make an artillery minigun?

1.12K 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?

There is a whole other problem that has been ignored so far: counter battery fire.

Modern war uses radar to track incoming artillery rounds, feeds that information to artillery units and then fires artillery back at the first artillery unit. And if successful the first artillery unit fires off several rounds and then explodes because the counter battery fire hit them. 

So modern artillery involves firing 1-2 rounds, and then immediately packing up and moving 1-2 miles down the road before the counter battery artillery gets involved. So a drum fed artillery system would never be able to sustain fire because counter battery would destroy it long before it could empty the clip.
