So it will be!
The "Intervall-gun" is a very advanced weapon system, it is based on 5-dimensional fields. The PKW-sized system emites, through a 20cm dish, a 5d wavefront that crumbles everything to dust that is in his five million km effectiv fireing range. Thats the basic-non-scientifical-version.

An exact explanation is in the data core i'll hand to you.
The gun may be installed in every ship that has the necessary hole in its hull for the dish. There is no need for an additional powercore because the system has an internal powercore.
I think this is all a normal fighter needs to know, it will frag an enemy ship to the frag size of toothpicks.
Everything else is for the scientists.
don't mind asking if anything ele is unclear.
