Context:
  • On Wednesday, 20 August 2025, India successfully test-fired its Intermediate-Range Ballistic Missile (IRBM), Agni-5, from the Integrated Test Range located at Chandipur, in the state of Odisha.
  • The test was carried out under the Strategic Forces Command, which is part of India’s Nuclear Command Authority.
  • As per the official statement by the Ministry of Defence, the test:
    • Validated all operational and technical parameters
    • Demonstrated readiness for deployment in India's strategic arsenal
AGNI 5: INTERMEDIATE RANGE BALLISTIC MISSILE explained for UPSC
  • The test involved a variant of the Agni-5 missile, which was designed and developed indigenously by the Defence Research and Development Organisation (DRDO).
  • This development follows a previous test conducted on 11 March 2024, during which Agni-5 equipped with Multiple Independently Targetable Re-entry Vehicle (MIRV) technology was successfully trialed.

WHAT IS MIRV TECHNOLOGY?

  • Multiple Independently Targetable Re-entry Vehicle (MIRV) refers to a missile’s ability to:
    • Carry multiple nuclear warheads.
    • Target different locations independently from a single missile launch.
  • Strategic Advantages:
    • Overwhelms enemy missile defense systems.
    • Enhances first-strike and second-strike capabilities.
    • Reduces the number of missiles needed to hit multiple targets.

MISSILE RANGE CLASSIFICATION (BALLISTIC MISSILES)

Classification Range
Short-Range Ballistic Missile Less than 1,000 kilometers
Medium-Range Ballistic Missile 1,000 to 3,000 kilometers
Intermediate-Range Ballistic Missile 3,000 to 5,500 kilometers
Intercontinental Ballistic Missile More than 5,500 kilometers
Although Agni-5 is officially categorized as an Intermediate-Range Ballistic Missile, its actual operational range exceeds
5,000 kilometers, bringing it close to Intercontinental Ballistic Missile capabilities.

STRATEGIC FORCES COMMAND & NUCLEAR COMMAND AUTHORITY

  • Strategic Forces Command:
    • A tri-service command responsible for the operational management of India's nuclear arsenal.
    • Executes the orders of the Nuclear Command Authority.
  • Nuclear Command Authority:
    • Apex body overseeing the policy, command, and control of nuclear weapons.
    • Operates under India’s No First Use (NFU) doctrine and Credible Minimum Deterrence

STRATEGIC SIGNIFICANCE OF AGNI 5

  • Enhances India’s long-range deterrent capability.
  • Strengthens India’s second-strike capability, crucial for maintaining nuclear stability in South Asia.
  • Allows India to maintain minimum credible deterrence under its No First Use
  • Equips India to target regions far beyond its immediate neighborhood, including all of Asia and parts of Europe.
  • Provides strategic counterbalance to China’s long-range missile arsenal.
  • Contributes to technological self-reliance in strategic defence systems.
