INS Arighaat and Nuclear Policy of India

Syllabus :GS 3/Science and Tech 

In News

  • India’s second nuclear-powered ballistic missile submarine, the INS Arighaat, was commissioned into service at Visakhapatnam

About INS Arighaat

  • It features several technological upgrades compared to its predecessor, INS Arihant.
  • Both submarines share the same reactor and dimensions but Arighaat incorporates advanced design and manufacturing technology.
  • Construction and Indigenization: The submarine involved advanced technology, special materials, and skilled workmanship.
    • It includes indigenous systems and equipment developed by Indian scientists and industry.
  • Importance : INS Arighaat enhances India’s nuclear triad, which includes land-based missiles, aircraft, and nuclear-powered submarines (SSBNs) with ballistic missiles.
    • It strengthens India’s nuclear deterrence and contributes to maintaining regional strategic balance.
INS Arihant
– INS Arihant was the first of its kind, commissioned in 2016 after its launch in 2009.
– INS Arihant is armed with a K-15 SLBM (750 km range) and a K-4 SLBM (3,500 km range) is under development.
– The K-4 SLBM will enhance India’s undersea nuclear deterrence.
1.The nuclear triad completion was announced in November 2018.
– A third submarine in the class is under construction, expected to be larger and more capable.

Nuclear Doctrine:

  • Historical Context: In 1962 India’s nuclear weapons development began after the 1962 war with China and China’s 1964 nuclear test.
    • In 1974 India conducted its first nuclear test, Pokhran-I, termed as a “peaceful nuclear explosion.”
    • In 1998  India conducted Pokhran-II tests, which included fission and thermonuclear devices, demonstrating capability to integrate nuclear warheads with its missile program.
  • Features 
    • Credible Minimum Deterrence: India aims to maintain a credible minimum deterrence.
    • No First Use (NFU) Policy: Nuclear weapons will only be used in retaliation against a nuclear attack on Indian territory or forces.
    • Massive Retaliation: Nuclear retaliation to a first strike will be massive and designed to inflict unacceptable damage.
    • Authorization: Nuclear retaliatory attacks can only be authorized by the civilian political leadership through the Nuclear Command Authority (NCA).
    • Non-Use Against Non-Nuclear States: India will not use nuclear weapons against non-nuclear weapon states.
    • Response to Biological/Chemical Attacks: India retains the option of nuclear retaliation in the event of a major biological or chemical attack.
    • Export Controls and Treaties: Continued strict controls on nuclear and missile-related material exports, participation in the Fissile Material Cutoff Treaty negotiations, and adherence to the moratorium on nuclear tests.
    • Commitment to Disarmament: Ongoing commitment to global, verifiable, and non-discriminatory nuclear disarmament.

Challenges and Issues

  • India still lags behind bigger nuclear powers, with the US, Russia, and China possessing more advanced nuclear subs. 
  • China’s expanding fleet of nuclear-powered submarines and Pakistan’s potential development of sea-based nuclear deterrence pose challenges to India.
  • Some argue India’s “No First Use” (NFU) policy and emphasis on a small arsenal may undermine credible deterrence.
  • Critics believe the doctrine’s focus on “minimum deterrence” and “massive retaliation” may not be sufficient against evolving threats.

Suggestion  and Way Forward 

  • China’s advanced Anti-Submarine Warfare (ASW) capabilities and increased submarine deployments in the Indian Ocean highlight the need for India’s robust deterrence.
  • India’s nuclear capabilities should be assessed relative to China and Pakistan, both of which have advanced arsenals.
  • The commissioning of INS Arighaat is crucial for maintaining a credible second-strike capability amid growing nuclear threats from China and Pakistan.
  • To ensure continuous at-sea deterrence, India should aim to expand its SSBN fleet, with a suggested goal of at least six SSBNs.
