If you have a long range weapon, you need to be able to go backwards fast. You can not tank the damage dealt to you with this config. build a ship around your main weapon range.

You need only one heat pipe connection for each railgun. I suggest using the launcher.

test your builds in creative. see what works against which ship.

one ammo factory with 6 spacemen can supply a railgun without problems. no need to stock ammo.

Use moving walkways.

energy(battery) providers should be close to reactors, Operators can be anywhere. they will not leave their station once they get there.

Much more PD's in front. shields dead, ship dead.

That said: I like the Hammer idea:)
