Agni-III

Agni-III was developed by India's DRDO and Advanced Systems Laboratory as a larger intermediate-range ballistic missile for the Strategic Forces Command. It followed the shorter Agni-I and Agni-II systems and pushed India's land-based deterrent toward deeper regional reach. Its testing history, including early failure and later successful firings, shows the normal maturation path from prototype to deployed strategic system.

The missile is described as a two-stage solid-propellant IRBM with a larger diameter and payload than Agni-II. Its public range estimates place it in the 3,000 to 3,500 km class, with road mobility possible and rail mobility associated with deployment concepts. The design gives India a system able to hold more distant strategic targets at risk without moving directly to the Agni-V class.

Agni-III entered service alongside Agni-II and became part of India's layered nuclear-capable missile force. Its importance comes from filling the range gap between Pakistan-focused systems and longer-range China-facing missiles. For HiWars readers, it helps explain how India's deterrent posture is built from a family of related but differently ranged missiles.
