The most vital component of missile technology in recent years is the deployment of Multiple Independently targetable Re-entry Vehicle (MIRVs). The fundamental characteristic of deploying MIRVs is its ability to deliver several warheads along separate trajectories, which confers it flexibility of multiple targeting. The independent targeting capability enhances missile’s ability by exhausting the missile defence, providing deep penetration and potential of destruction of larger area, effectively and precisely. The vital advantage of MIRVs in terms of nuclear capability is very high yield, which, facilitate hitting hard targets and wide area. With same amount of nuclear warhead MIRV can increase yield upto 8 times the normal yield. With minimum nuclear warhead capability we can have exponential area damage.
