This topic of “[Indepth] Mission Divyastra & MIRV Technology – Explained” is important from the perspective of the UPSC IAS Examination, which falls under General Studies Portion.

Background and evolution of India’s Agni missile series

• The Agni missile program was initiated in 1983 by India’s Defence Research and Development Organisation (DRDO) to develop a series of nuclear-capable ballistic missiles.
• Agni-1 was the first missile in the series, a short-range ballistic missile with a range of 700 km, inducted into service in the early 2000s.
• Subsequent versions increased the range and payload capabilities:
  • Agni-2 (2,000-2,500 km range) in 1999
  • Agni-3 (3,500 km range) in 2011
  • Agni-4 (4,000 km range) in 2012
• Agni-5, successfully tested in 2012, is an intercontinental ballistic missile (ICBM) with a range over 5,000 km.
  • It features a three-stage solid fuel engine and road-mobile canisterized launch system.
  • Initial range estimates were around 5,000-5,500 km, but some reports suggest it could reach 8,000 km.
• The latest successful test on March 11, 2024 was of an Agni-5 missile integrated with MIRV (Multiple Independently Targetable Re-entry Vehicle) technology.
  • This allows a single missile to deliver multiple warheads to different targets.
  • It significantly enhances India’s strike capabilities and deterrence potential.
• DRDO is also working on developing the longer-range Agni-6 ICBM, expected to have a range of 9,000-12,000 km.

The Agni missile program has steadily evolved over decades, with each successive version increasing India’s strategic strike capabilities and establishing it as a major missile power.

Multiple Independently Targetable Re-entry Vehicle (MIRV) technology

• MIRV technology allows a single missile to carry multiple nuclear warheads, each capable of striking different targets independently.
• It consists of a maneuverable “bus” or post-boost vehicle that can release multiple reentry vehicles (RVs) containing warheads on different trajectories towards separate targets.
• This provides several strategic advantages:
  • Increases the missile’s target coverage and destructive potential
  • Complicates missile defense by presenting multiple targets to intercept
  • Allows more efficient use of a limited number of delivery vehicles
• The Agni-5 test successfully demonstrated the deployment of multiple RVs from a single missile.
• India has now joined a select group of countries with operational MIRV capabilities, including the US, Russia, China, France and the UK.
• MIRV was originally developed in the 1960s-70s by the US and USSR to defeat anti-ballistic missile (ABM) defenses during the Cold War.
• While increasing a missile’s destructive power, MIRV technology is also destabilizing as it incentivizes preemptive strikes during conflicts.
• Integrating MIRV on the long-range Agni-5 significantly enhances India’s nuclear deterrence against China and its ability to strike multiple targets.

The successful MIRV test marks an important technological milestone for India’s strategic capabilities, but also raises concerns about potential nuclear arms racing in the region.

Strategic implications of Mission Divyastra and India’s acquisition of MIRV technology

Strategic Posture and Deterrence:

• Significantly enhances India’s nuclear deterrence capabilities against potential adversaries like China and Pakistan.
• Allows India to credibly target multiple high-value sites with a single MIRV-equipped missile like Agni-5.
• Complicates missile defense efforts by adversaries due to multiple reentry vehicles to track.
• Strengthens India’s regional power projection and second-strike capabilities in the event of a nuclear attack.
• Demonstrates India’s indigenous technological prowess in strategic missile technology.

Geopolitical Implications:

• Could potentially trigger a nuclear arms race and destabilize the regional balance of power.
• May compel China to accelerate its own MIRV and counter-force programs.
• Increases pressure on Pakistan to develop countermeasures and more advanced delivery systems.
• Raises concerns among smaller neighbors like Bangladesh about the potential fallout of India-Pakistan tensions.
• Could prompt renewed international scrutiny on India’s nuclear program and non-proliferation commitments.
• May strain India’s relations with major powers advocating for global nuclear disarmament.

While boosting deterrence, MIRV also introduces new risks and uncertainties in South Asia’s fragile security dynamics.
