Test Firing the Missile include lot of stages 1 stage- Lounch Vehicle ( in this require Submarine that we dont have right now )
2 stage - Ejacuation i.e. From launch vehicle
3 stage - Distance travel ( 700 Km )
4 stage - then Hiting target ( It is called Pin Point Accuracy)
These are few stage that I know I think there are many more stages in One Test fire of Missile U have written about capacity of distruction I would like to remind u that this is NUKE WEAPON so they dont use real Nuke they calculate the impact ( their Data is very Accurate ).
Another thing is WE ARE NOT DEVELOPING WEAPON TO DESTROY ANY NATION WE ARE MAKE WEAPON BY USING OUR OWN BRAIN TO PROTECT OUR NATION.
NUKE WEAPON ARE THE THING THAT KEEP PEACE IN THE WORLD.
FOR EXAMPLE IRAN WANTS TO MAKE NUKE WEAPON BUT USA OPPOSING BIGGEST REASON IS IN FUTURE USA CANT ATTACK ON IRAN ON THE NAME OF TERRORISM LIKE AFGANISTAN OR LIKE IRAQ.
OTHER NATION ARE OPPOSING B'COZ IRAN CAN START WAR WITH HIS ENEMY AND END UP KILLING ITSELF AND OTHER NATIONS IN THE WORLD ( LACK OF MATURE IDEOLOGY OR THINKING )
