Odisha: Agni-4 Missile Tested Successfully, Pg10

Key Highlights:

• India successfully test-fired the nuclear-capable ballistic missile Agni-4 on August 6, 2026.
• The test was conducted from the Integrated Test Range at Chandipur, Odisha.
• The launch was carried out jointly by the Strategic Forces Command (SFC) and the Defence Research and Development Organisation (DRDO).
• Agni-4 is an intermediate-range ballistic missile with a strike range of 4,000 km.
• The successful test demonstrates India's strategic strike capabilities and reinforces its credible minimum deterrence.

Detailed Insights:

• The Agni-4 missile is a surface-to-surface missile capable of carrying a 1,000 kg payload.
• It utilizes a two-stage solid propulsion system, incorporating advanced technologies like composite motor casing and improved guidance systems.
• The Integrated Test Range (ITR) in Chandipur, Odisha, provides a crucial facility with an open sea range for safe missile testing and data acquisition.
• The Strategic Forces Command (SFC) is responsible for the management and administration of India's tactical and strategic nuclear weapons stockpile.
• The SFC operationalizes directives from the Nuclear Command Authority (NCA), which is responsible for command and control decisions regarding India's nuclear weapons program.
• The Defence Research and Development Organisation (DRDO) is the primary research and development wing of the Ministry of Defence, focused on achieving self-reliance in critical military technologies.

Scientific/Technical Concepts Involved:

• Ballistic Missile: A missile that follows a high-arching trajectory, launched by rocket propulsion, and re-enters the atmosphere at high speed towards its target.
• Intermediate-Range Ballistic Missile (IRBM): A ballistic missile with a range typically between 3,000 km and 5,500 km, like the Agni-4.
• Solid Propulsion: A type of rocket engine that uses solid propellants, offering simpler design and easier storage compared to liquid propellants.
• Credible Minimum Deterrence: A nuclear posture adopted by states like India, maintaining a nuclear arsenal sufficient for effective retaliation to deter aggression without an arms race.
