Context:
The Defence Research and Development Organisation (DRDO), in partnership with the Strategic Forces Command (SFC), has successfully conducted the test launch of the Intermediate Range Agni-Prime missile using a rail-based mobile launcher system.
Key Features:

- This launch places India among a select group of nations, including Russia, the United States, China that possess the ability to deploy long-range ballistic missiles from rail platforms.
- This next generation missile is designed to cover a range up to 2000 km and is equipped with various advanced features.
- This missile boasts several advanced features, including enhanced precision, faster reaction time, and improved mobility.
- The launcher can seamlessly move across the rail network without any preconditions and offers cross-country mobility.
- This launch also complements the road-mobile version of Agni-P, which has already been inducted into the armed forces after a series of successful trials.
Rail-Based Mobile Launcher
- The missile was launched from a first-of-its-kind rail-based mobile launcher specially designed for deployment on India’s extensive rail network.
- Road-based missile systems have route limits, but India’s vast 70,000 km rail network allows missiles to reach all parts of the country.
- Unlike conventional fixed or road-mobile launchers, this rail-based system offers several strategic advantages:
- Unrestricted Mobility: The launcher can traverse the entire rail network without any pre-conditions or restrictions, allowing for rapid redeployment.
- Cross-Country Movement: Beyond rail tracks, it supports cross-country mobility, enhancing survivability.
- Quick Reaction Time: The system is capable of launching missiles within a very short timeframe, reducing response times.
- Reduced Visibility: Its mobile nature and camouflage capabilities provide stealth and protection against enemy detection.
- Self-Sustained Operation: Equipped with independent launch systems, state-of-the-art communication tools, and protective mechanisms, the launcher is a fully autonomous unit.
Agni-Prime and Agni-5

Agni-P: A Strategic Upgrade
- The Agni missile series, central to India’s ballistic missile program since the late 1980s, has evolved to meet changing strategic needs. Agni-I, tested in 1989, was a medium-range missile with a 700-1,000 km range.
- The Agni-Prime (Agni-P) builds on this by combining Agni-I’s range with advanced propulsion and navigation tech from Agni-IV and Agni-V.
- This two-stage, solid-fuel missile weighs around 11,000 kg and has a range of 1,000 to 2,000 km, capable of carrying high-explosive, thermobaric, or nuclear warheads.
- The successful nuclear-capable test in 2021 boosted India’s credible deterrence, and the recent rail-based launch enhances its survivability and deployment flexibility.
