Development of the Agni Missile Program

India’s Agni missile program is one of the cornerstones of its strategic defense framework.

It began under the Integrated Guided Missile Development Program (IGMDP) initiated in the early 1980s under the leadership of Dr. A.P.J. Abdul Kalam, often called the “Missile Man of India.”

The Agni series was envisioned to provide India with a range of ballistic missiles capable of delivering conventional and nuclear warheads at varying distances, giving the country a credible deterrence and defense system.

The Agni-1 missile, which has a shorter range of about 700–1,200 km, was a crucial first step.

Agni 2 followed as the second missile in the series, with the aim to extend India’s reach and improve the strategic flexibility of its armed forces.

The Agni II missile represented a leap in range and accuracy, crucial for countering threats from neighboring countries, especially with nuclear-capable delivery systems.

Importance of Agni 2 in India’s Nuclear Doctrine

India follows a No First Use (NFU) nuclear policy, meaning it would only use nuclear weapons in retaliation to a nuclear attack.

In this context, the Agni II missile plays a pivotal role in ensuring that India has a credible second-strike capability.

The second-strike capability is critical for deterrence because it guarantees that even if a country is attacked with nuclear weapons, it can still respond with devastating force, thereby discouraging any first-strike from an adversary.

With its range extending up to 3,000 kilometers, Agni II can target key installations deep within enemy territory.

It provides India with strategic depth, allowing it to deploy a formidable deterrent over vast distances.

Technological Features of Agni 2
