Smaller Weapons
It is possible to equip a spacecraft with Ground scale weaponry. This is usually done on small craft designed to operate regularly within an atmosphere while engaging ground targets but any spacecraft can use them.
Any weapon with a mass less than 250 kg can be mounted on a spacecraft at a cost of Cr1000 (the cost of the actual weapon is in addition to this). They will draw no Power from the spacecraft, as it is assumed their energy requirements are tiny in comparison to other systems, and nor do they require a hardpoint, but will consume 1 ton. However, up to four such weapons may be mounted for each ton dedicated to them. They will be attached to fixed mounts on any spacecraft of less than 50 tons, and small pop-up turrets operated from a remote station on larger ships.
Weapons of a mass of 250 kg or more will consume an amount of space equal to their mass, to a minimum of 1 ton. They are required to be mounted in turrets (if they mass one ton or less) or fixed mounts and again, will consume no power.
