Not this kind, drones don't fire 155mm artillery shells.

Artillery has a relatively short range of ~30km, while modern drones are reaching hundreds of km.

Artillery and drones do different things. An artillery shell costs ~$2k and provides a much bigger bang (and faster speed, totally non-jammable) than a $2k drone (a shahed is ~$20k and much more intercept-able). Drones are 100% useful, but so is artillery.
