From the UPSC perspective, the following things are important:

Prelims level: INS Arihant, Nuclear Triad, ATV project

Mains level: Boost to India’s security establishment with nuclear triad becoming operational


India announces complete nuclear deterrence

  1. India has declared that its nuclear triad, stated in its nuclear doctrine, is operational
  2. This was after indigenous ballistic missile nuclear submarine INS Arihant achieved a milestone by conducting its first deterrence patrol
  3. It essentially means that Arihant is now prowling the deep seas carrying ballistic missiles equipped with nuclear warheads
  4. The second submarine in the series, Arighat is now undergoing sea trials after which it will be inducted into service

Development of INS Arihant

  1. INS Arihant, a strategic asset, was developed for over two decades under the Advanced Technology Vessel (ATV) programme
  2. INS Arihant is India’s first indigenously-designed, developed and manufactured nuclear-powered ballistic missile submarine, and three more such submarines are reportedly under various stages of construction
  3. INS Arihant development project was officially acknowledged in 1998 and the submarine was launched in 2009
  4. The nuclear reactor of the submarine went critical in 2013 and it was commissioned three years later

Reliability of INS Arihant

  1. It comes directly under the Nuclear Command Authority headed by the Prime Minister
  2. Given India’s stated position of ‘No-First-Use’ (NFU) in launching nuclear weapons, the SSBN is the most dependable platform for a second-strike
  3. Because they are powered by nuclear reactors, these submarines can stay underwater indefinitely without the adversary detecting it. The other two platforms — land-based and air-launched are far easier to detect
  4. This places India in the league of the few countries that can design, construct and operate SSBN

About NFU policy

  1. In 1998, India conducted nuclear tests under Pokhran-II and in 2003, it declared its nuclear doctrine based on credible minimum deterrence and an NFU policy while reserving the right of massive retaliation if struck with nuclear weapons first
