Re: Indian Missiles and Munitions Discussion

at somepoint on this thread we crossed a point which is docking into a GEO sat serving different strategic goals and killing the sat is not one of them, however it employs kill vehicle technology which is ABM derivative any ways

Re: Indian Missiles and Munitions Discussion

agree with you, the justification for a GEO mission is from an economics angle, and the kill vehicle technology is employed as well and can be on a routine basis, another implication is Agni SLV variant can use larger boosters in pursuit of this goal one that serves as a precursor to a full blown IC...
