You can get it to work by making a mod that removes the references to the superweapons in each race's players files (i.e. each PlayerRACE.entity file).
Thx for trying to help me 
I hope you mean the Playerphase, playerpsi etc. It is enough to delete this for each race:
entityDefName "PLANETMODULE_PHASEORBITALCANNON"
Are these files the only one that i need to make this mod working. Im not so good @ moding. I only could do the 99 trick, because of a good instruction found here.
Okay, no super weapons can be build by me. Does it work to for the ai too?
