Not this way, I thought about giving it initial speed with rail gun, and then satellite would use its own engine. However the initial work to get it off the ground could be use by system of electromagnetic rails. Actually I have been thinking that if international treaty actually allows weaponization of space then we can expect colonies on Moon, then on Mars much sooner then after. I would actually do it the other way around then it is now. Allow military interventions in space, but not on Earth :P
