I've checked, and repulsor beams work on weapon platforms. They are ineffective on sats.

I do have a concern with the Inertial Negator operating on the smallest ships.
There is no way that I can have the ES with 1EPM.
Using quantum engines, you could design a plaguebomber with 60 movement points! That's 30 in combat!

I might have to change the I.N. into a third form, and have it give you an engine that provides +1 thrust (plus a cheaper Version at higher tech). That would make Ion engines be the same as your opponent's CT engines, etc.
