Britain just shipped the first Sheffield-forged artillery barrels to Ukraine, the first the UK has produced in nearly twenty years, after Britain let its forging capability go dark believing the post-Soviet peace was permanent. There are 146 more barrels planned. The Luftwaffe bombed Sheffield twice in 1940 because they understood a forge city wins wars.
Think of artillery like this, drones are better at delivering the first lets say ~15 munitions than artillery, but what about the 1000 after that?
Drones make for excellent artillery spotters too.
See one target? Hit it. See ten targets? Let the big boys hit it.
