📌 Why in News?
**Context
The Strategic Forces Command (SFC)** successfully conducted a routine training launch of the Agni-IV intermediate-range ballistic missile off the coast of Odisha. About The Agni-IV Ballistic Missile: Agni-IV is an indigenous, nuclear-capable, two-stage solid-fueled Intermediate-Range Ballistic Missile (IRBM).
Syllabus & Relevance
Prelims: Science & Technology — institutions, terminology and factual features connected with the development.
Mains: GS-3 — contemporary application of the relevant syllabus theme.
Current–static link: Revise the underlying institution, policy or concept together with this development.
Why it matters for India
Operating with a strike range of approximately 4,000 kilometers, it serves as a core land-based component of India’s nuclear triad.
Aim: To provide a highly mobile, survivor-capable, and precise land-based nuclear deterrent against regional strategic threats across Asia, strengthening India’s policy of Credible Minimum Deterrence and No First Use.
Road mobility and rapid launch capability improve survivability against preemptive attacks, strengthening India’s nuclear deterrence.
Static Foundation
Agni-IV is an indigenous, nuclear-capable, two-stage solid-fueled Intermediate-Range Ballistic Missile (IRBM).
Operating with a strike range of approximately 4,000 kilometers, it serves as a core land-based component of India’s nuclear triad.
Designed & Developed By: Defence Research and Development Organisation (DRDO).
Aim: To provide a highly mobile, survivor-capable, and precise land-based nuclear deterrent against regional strategic threats across Asia, strengthening India’s policy of Credible Minimum Deterrence and No First Use.
Extended Strike Range: Capable of delivering a 1-tonne (1,000 kg) conventional or nuclear warhead up to a distance of 4,000 kilometers.
Solid-Propellant Propulsion: Powered by a high-performance two-stage solid-fuel engine housed in lightweight composite rocket motor casings.
Road-Mobile Survivability: Transportable and launchable via mobile Transporter Erector Launchers (TELs), enabling rapid repositioning across countrywide road networks to avoid targeting by enemy silo-tracking assets.
Data, Reports, Cases & Examples
