India may be preparing for its biggest missile leap yet.After DRDO chief Samir V Kamat confirmed that the organisation is ready for the Agni-VI programme pending government approval, speculation around India’s next-generation intercontinental ballistic missile has intensified. The buzz grew further after the BJP publicly highlighted the missile’s reported 10,000-km-plus strike range and MIRV capability.But why does India even need such a long-range missile when its two main adversaries, China and Pakistan, are geographically much closer?In this video, we explain what exactly an ICBM is, how Agni-VI could differ from Agni-V, what MIRV technology means and why modern deterrence is no longer only about distance.To put it in perspective, a 10,000-km missile could place all of China, Pakistan and even parts of Europe within striking range while being launched from deep inside Indian territory.We also examine how changing missile warfare, hypersonic weapons and evolving air defence systems are reshaping global deterrence calculations, and why India’s strategic thinking may be evolving alongside them.Because Agni-VI is not just about hitting farther, but also about survivability, retaliation capability and ensuring deterrence remains credible in a rapidly changing security environment.
