India recently conducted a successful test of the Agni-Prime (Agni-P) missile using a rail-based mobile launcher. This achievement places India among a select group of nations capable of launching long-range ballistic missiles from railway platforms. The test marks step in strengthening India’s second strike nuclear capability and its strategic deterrence posture.
Significance of Rail-Based Missile Launchers
Rail-based launch platforms enhance a country’s ability to survive a nuclear attack and retaliate effectively. Unlike stationary silos, which are vulnerable to precise missile strikes, mobile launchers can be moved and concealed. Rail systems offer greater operational flexibility than road-based platforms due to India’s extensive 70,000 km railway network. The presence of numerous tunnels allows missile launchers to hide from enemy satellite surveillance until deployment, increasing survivability. Rail-based systems are also more cost-effective compared to submarine-launched ballistic missiles, making them scalable and easier to maintain.
India’s Nuclear Doctrine and Second Strike Capability
India follows a no first use nuclear policy, meaning it will only use nuclear weapons in retaliation. This makes second strike capability essential. Mobile missile launchers on railways ensure that India can respond to any nuclear attack by launching a counterattack even if fixed missile silos are destroyed. This capability strengthens deterrence and promotes strategic stability by assuring adversaries that a retaliatory strike is inevitable.
Evolution of the Agni Missile Series
The Agni missile series began development in the late 1980s with Agni-I, a medium-range ballistic missile with a range of 700 to 1,000 km. Over time, India has upgraded this platform to enhance range, accuracy, and survivability. The Agni-Prime is an advanced two-stage solid-fuel missile combining the range of Agni-I with propulsion and guidance technologies from longer-range Agni-IV and Agni-V missiles. It has an operational range of 1,000 to 2,000 km and can carry conventional or nuclear warheads.
Strategic and Technological Implications
The successful test of Agni-P from a rail-based launcher demonstrates India’s growing technological prowess in missile development and strategic deployment. It signals India’s entry into an elite group of countries with canisterised rail-launch capabilities, including Russia, the US, China, and possibly North Korea. This development enhances India’s strategic deterrence by improving missile mobility, concealment, and survivability against modern surveillance and attack technologies.
