Correct answer
Agni-Prime
Why this answer is correct
The correct answer is Agni-Prime.
Key Points
- The Defence Research and Development Organisation (DRDO) successfully flight-tested the Agni-Prime (also known as Agni-P) missile on 24 September 2025.
- This specific test was significant as it was conducted from a rail-based mobile launcher, enhancing the strategic flexibility and survivability of the missile system by allowing it to be moved across the country’s vast railway network.
- The launch was carried out under full operational conditions, validating the reliability of the entire weapon system, including the propulsion, control systems, and navigation technologies.
- The mission met all objectives, confirming the high degree of accuracy and precision of the missile. This test represents a major milestone in India’s transition toward modern canisterized missile systems.
- The flight test took place at the Dr. APJ Abdul Kalam Island located off the coast of Odisha, which is the primary site for India's strategic missile testing.
Additional Information
- Agni-Prime Missile Features:
- Type: It is a two-stage solid-propellant ballistic missile that belongs to the new generation of the Agni series.
- Range: It has a strike range of 1,000 to 2,000 kilometers, making it a medium-range ballistic missile (MRBM).
- Canisterization: The missile is canisterized, meaning it is stored in a sealed tube. This allows for easier transport, longer shelf life, and significantly reduces the time required for launch.
- Navigation: It incorporates advanced Ring Laser Gyro-based Inertial Navigation Systems (RINS) and Micro Navigation Systems (MINS) for superior guidance.
- Strategic Significance:
- Agni-Prime is designed to replace the aging Agni-I and Agni-II missiles in the Indian inventory.
- The rail-based launcher capability ensures that the missile can be hidden and moved quickly, making it harder for enemy reconnaissance to track and target India's nuclear deterrent.
- It contributes to India’s policy of Credible Minimum Deterrence and its "No First Use" nuclear doctrine.
- Evolution of Agni Series:
- The Agni missiles were developed under the Integrated Guided Missile Development Programme (IGMDP), spearheaded by Dr. APJ Abdul Kalam.
- The family includes variants ranging from the short-range Agni-I (700 km) to the Intercontinental Ballistic Missile (ICBM) Agni-V (over 5,000 km).
- Unlike the older liquid-fuel missiles, modern Agni-Prime uses composite motor casings and advanced materials to reduce weight and increase efficiency.
Important Points
- DRDO: Headquartered in New Delhi, it is the R&D wing of the Ministry of Defence. It was formed in 1958 by merging the Technical Development Establishment and the Directorate of Technical Development and Production.
- Operational Readiness: Full operational condition tests are usually conducted by the Strategic Forces Command (SFC) in coordination with DRDO to ensure that the user (the military) is capable of handling the equipment in real-world scenarios.
- Mobility: While road-mobile launchers are common, rail-mobile versions provide an extra layer of strategic depth because of India's extensive railway infrastructure, allowing for rapid redeployment across thousands of kilometers.
