I made a ship with mine launchers:

I found that mines can be incredibly powerful against ships without much flak:
-The mines themselves, before they explode, can go through shields
-They fire out tons of projectiles, which can each be almost as strong as a missile (I think)
-Missiles and Railguns have a limited range, but mines last a long time, so if you are kiting an enemy farther than their railguns can shoot, you can let mines behind you and they will reach the enemy (only if you're traveling in a straight line, and the enemy doesn't have flak).
I also made this: (The structure shows how far the mines need to go before they activate)
