With Agni V test, India makes the MIRV leap

Subject: Science and tech

Section: Defence

Context:

  • On March 11, Prime Minister Narendra Modi announced on social media the successful flight test of an Agni V ballistic missile with multiple independently targetable reentry vehicle (MIRV) technology.

What are MIRVs and why are they significant?

  • A MIRV is a ‘missile bus’ whose passengers are nuclear bombs and which facilitates a single booster to deliver them to different targets.
  • MIRVs are a “force multiplier” because one MIRV-ed missile can strike several targets.
  • MIRVs are also useful for saturating and penetrating ballistic missile defenses.
  • In 1970, the U.S. started to deploy the Minuteman III, the first MIRV-ed intercontinental ballistic missile (ICBM) with three warheads on each missile. 
  • In 1971, it deployed the Poseidon, the first MIRV-ed submarine-launched ballistic missile (SLBM).
  • The Soviet Union followed the U.S. and by the 1970s developed its own MIRV-ed ICBM and SLBM technology.
  • The U.K. and France also possess the technology.
  • China has developed and deployed MIRV technology with multiple warheads placed on its DF-5B ICBMs and is fast expanding and modernizing its nuclear arsenal.

What was the Mission Divyastra test?

  • The MIRV system is equipped with indigenous avionics systems and high accuracy sensor packages that ensure the re-entry vehicles reach the target points with the desired accuracy.
  • The ‘Agni’ series of missiles constitute the backbone of India’s nuclear weapons delivery, and Agni V is the longest range missile in the arsenal, with a reach of over 5,000 km.
  • This means it can reach most of China, especially with a smaller warhead, which would increase the range further.
  • MIRV technology gives better leverage in this regard.
