How does Nuclear Deterrence Work in India?

The executive council of the NSA advises the political council of the NSA in case of any security threat or nuclear action needed. The political council gives orders to Strategic Nuclear Command.

Strategic Nuclear Command possesses all major nuclear arsenals, and it is the agency responsible for executing a nuclear retaliation. SNC requires approval from NCA for any nuclear action. Recent estimates suggest that India has between 90 and 110 nuclear weapons. 

Nuclear Triad

Nuclear Triad is a term used to denote a nation that has the capabilities of a nuclear strike from land, air, and water. India has tested its abilities on land, air, and sea.

  • From Land: Ballistic missiles with a nuclear warhead in the Prithvi and Agni Series.
  • From Air: Nuclear bombs from Dassault Mirage 2000s and SEPECAT Jaguars. (Free-falling and un-guided method).
  • From Sea:  Submarines: Sagarika K-15 missile in Arihant Submarine; Ship: Dhanush missile from ships like INS Subhadra or INS Rajput.

  • Developing anti-satellite weapon (ASAT) capabilities; successfully carried out an ASAT missile test in March 2019
  • Possesses several types of operational nuclear-capable land-based ballistic missiles, SLBMS, and cruise missiles
