On 8 May 2026, the Ministry of Defence (MoD) announced a successful flight‑trial of an advanced version of the nuclear‑capable Agni‑5 missile from Dr APJ Abdul Kalam Island. The test marks India’s entry into the exclusive club of nations possessing operational MIRV capability.
Key Developments
- Integration of MIRV on Agni‑5, extending its strategic reach.
- Rupee fell to a record low of ₹95.63 per US$, intensifying import‑cost pressures and prompting Prime Minister Narendra Modi to urge fuel conservation and work‑from‑home measures.
- New research predicts a slowdown of the AMOC by up to 59% by 2100, with potential repercussions for the Indian monsoon.
Important Facts
• MaRV differs from MIRV by focusing on trajectory maneuverability rather than multiple warheads.
• In a floating exchange rate, the rupee’s depreciation makes imports costlier but can boost export competitiveness.
• Forex reserves are managed by the RBI, and act as a safety net during crises.
• The weakening of ENSO cycles could be amplified by a sluggish AMOC, leading to more erratic monsoon behaviour.
Exam Relevance
• Defence: Understanding MIRV and MaRV technologies is essential for GS2 questions on strategic deterrence, nuclear doctrine (no‑first‑use) and missile‑defence challenges.
• Economy: The rupee’s record low and its link to import‑dependent sectors test candidates’ grasp of exchange‑rate mechanisms, balance‑of‑payments and the role of forex reserves in macro‑stability.
• Environment: AMOC’s projected slowdown and its interaction with ENSO are pertinent to GS3 topics on climate change, monsoon variability and global‑regional linkages.
Way Forward
- Defence: Continue indigenisation of missile technologies, enhance second‑strike capability, and develop robust anti‑missile systems to counter MIRV threats.
- Economy: Monitor RBI interventions, diversify import sources, and promote export‑oriented policies to mitigate currency volatility.
- Environment: Strengthen climate‑resilience strategies, invest in monsoon forecasting, and cooperate internationally on ocean‑circulation research.
Overall, the convergence of strategic defence advances, currency fluctuations, and climate‑system risks underscores the interconnected challenges that UPSC aspirants must analyse across GS papers.
