So I posted about this on Reddit a while back but here's an idea: Legend of the Galactic Heroes-style laser turrets. Rather than having a gun mounted on a turret, it's a ball-style turret that's about 1x1x1 blocks wide , with a beam that instantly crosses the space between the turret and it's target. It's able to fire at targets up to 10km away.

The beams make no sound, and they do an incredible amount of damage, picture something like a coilgun or MAC round from one of the Halo mods, but with a wider damage radius (say about 5-6 meters) and rounds produced by the turret via power consumption. To balance this, the turrets have a very low rate of fire (30-45 seconds between shots) and are reasonably inaccurate, drifting up to 25 meters off-target at maximum range (10 km).

The end result is a large-ship 1x1x1 ball turret that performs fairly well against large ships, but is almost totally useless for point defence.

EDIT: I'd make this myself, but IDK how to mod :(

sounds quite overpowered, but i think i could make it work somehow if i decide to use this idea

Yeah, I may have been fairly tired when I posted that description, so it's full of errors. The damage radius should be about 2-3 meters, and at max range the maximum drift should be between 100 meters to 1 km.

basic idea is that if you've got between 8-10 lasers firing at maximum range, odds are that only 1-2 would actually hit their target. These things are meant for either knife-fighting range or stupidly massive salvos (think 10+ turrets firing at once).
