Question

With reference to Agni-IV Missile, which of the following statements is/are correct?It is a surface-to-surface missile.It is fuelled by liquid propellant only.It can deliver one-tonne nuclear warheads about 7500 km away.Select the correct answer using the code given below.

Accepted Answer

Correct Answer: A — 1 onlyStep-by-step Solution:Agni-IV is an intermediate-range ballistic missile (IRBM) developed by the Defence Research and Development Organisation (DRDO) of India, under the Integrated Guided Missile Development Programme (IGMDP).Statement 1 — Surface-to-surface missile: This is correct. Agni-IV is a surface-to-surface ballistic missile — it is launched from the ground/surface and strikes targets on the ground/surface. All Agni series missiles (Agni-I through Agni-V and beyond) are surface-to-surface ballistic missiles. ✓Statement 2 — Fuelled by liquid propellant only: This is incorrect. Agni-IV uses solid propellant in both its stages (two-stage solid fuel propulsion) — NOT liquid propellant. The advantage of solid propellant over liquid is that solid-fuel missiles can be stored fully fuelled and ready to launch at short notice, making them more suitable for military deployment. Earlier Agni variants used a combination or liquid propellant, but Agni-IV is solid-fuelled throughout. ✗Statement 3 — Range of 7500 km with one-tonne warhead: This is incorrect. Agni-IV has a range of approximately 3,500–4,000 km — capable of delivering a nuclear warhead of about 1 tonne. A range of 7,500 km is associated with the much longer-range Agni-V (which has an inter-continental range of 5,000–8,000 km). ✗Key Concept: Agni missile series: Agni-I — ~700 km range; Agni-II — ~2,000–3,000 km; Agni-III — ~3,000–5,000 km; Agni-IV — ~3,500–4,000 km (solid fuel, two-stage); Agni-V — ~5,000–8,000 km (ICBM range, canisterised for road/rail mobile launch). Agni-V is the most advanced in the operational series — capable of targeting all of China's major cities and parts of Europe. India is developing Agni-VI (MIRV capability, potentially ~8,000–10,000+ km). All Agni missiles are nuclear-capable and part of India's nuclear deterrent triad (land, sea, air).
