I would think the 'sheild buster' weapons would use some type of EMP (electro-magnetic pulse).
The Paraylyzer missle and it's lesser cousins would have a small atomic device similar to a tactical neutron bomb. Hence, little physical damage and massive elecrto-mechanical disruption. Not only could we make such space weapons today, but it is very likely there are already EMP missles deployed as satellite killers. By someone:blink:
I think with the 'pulse' series of weapons, the name says it. A focused EMP beam that shreads any energy field it comes in contact with. A small controlled series of "almost critical mass" explosions. Today's physics and limitations do not allow such containment and focusing of energy, but theoreticaly it could be done. The trick is, it takes energy to contain energy. I'm pretty sure that after the Mr Fusion goes into widespread production, that will not be a prob.
