You perhaps misunderstood me - i am not questioning this programme, infact very proud of it.
However fact of the matter is - we have not tested this programme with multiple incoming missile trajectories, we have not tested whether our fire and control is capable of tracking multiple incomming trajectories ( i am sure it is capable- since it is based on Swordfish), etc.
Further if we have just proven this programme against one incomming missile, pretty much sure that in a practical scenario this system will be overwhelmed. So as you stated above - it would not be half of the missiles which are destroyed - it would be just one, and rest skimming through the defences (speculation). I agree with you , one is better than none !! But still ..
Not sure why DRDO/IDS is rushing into deploying these systems - with very less imminent threat on the horizon.
Anyways i am not questioning this to the group, just wondering what would be the reason behind this deployment ? Perhaps it is more of warning Pakistan/China of this capability.
