DRDO ready with Agni-VI: Why this next-gen ICBM matters for India’s deterrence

An Intercontinental Ballistic Missile, or ICBM, is a long-range missile designed to travel more than 5,000 km. Unlike cruise missiles, which fly through the atmosphere using engines throughout their journey, ballistic missiles spend much of their flight outside the atmosphere, which means the missile actually leaves Earth’s air atmosphere and travels through space for part of its journey.
