Agni-IV is a surface-to-surface ballistic missile that is fuelled by both solid and liquid propellants. It has a range of approximately 4,000 km, which means it can travel up to 4,000 km from its launch site before striking its target. Agni-IV has been designed to be able to carry a one-tonne nuclear warhead and can deliver it at a distance of up to 4,000 km.
It is important to note that while the statement in the question was incorrect about the range of Agni-IV, the missile is still a significant part of India`s strategic deterrence capability. Agni-IV is designed to provide India with the ability to strike targets at long ranges, which enhances India`s strategic capabilities.
