Yes, its very much possible. We are now working on ion thrusters. This will give the ability to us to sow warheads in space in LEO and and maneuvre them to any height and intercept even GEO satellites. The hit to kill has been demonstrated. We can also place DEW in space now as mines which will derive energy from Sun and fire lasers at anything upwards as lasers do not degrade in space and very low power lasers can have 1000s miles of range in space.Aren't military coordination done by geostationary communication satellites rather than LEO spy satellites?? So other than destroying some space eyes, does it really add in anyway to our ability to disrupt enemy communications/coordination? Is it posible for us to develop GEO ASAT??
