Why ballistic missiles?
Ballistic missiles are the most effective delivery systems for nuclear warheads against fixed targets like cities and military bases, because of their short flight duration and and precise course , that cannot be altered once the missile spends its fuel and becomes ballistic. Defence against ballistic missiles are yet to be reliable enough to be considered foolproof , especially against long-range, high-speed ones like ICBMs (Inter Continental Ballistic Missiles) and SLBMs (Submarine Launched Ballistic Missiles). Moscow remains the only city in the world with a somewhat credible ABM (Anti Ballistic Missile) defence system, while the US National Missile Defence (NMD) project is still under development. Ballistic missiles coupled with MIRVed warheads are the deadlist nuclear weapons because of their high penetrability. The longest range ballistic missiles are made by China, USA and Russia. This limits our focus on these three countries and their most powerful ballistic missile systems in
