Paper: GS – III, Subject: Science and Technology, Topic: Defence Technology, Issue: INS Aridaman.
Context:
India’s induction of INS Aridaman, its third nuclear-powered ballistic missile submarine (SSBN), marks a major step in strengthening its nuclear deterrence and completing the operationalization of a credible nuclear triad.
Key Takeaways:
CORE ANALYSIS:
- Development: Induction of INS Aridaman increases India’s SSBN(Ship Submersible Ballistic Nuclear) fleet to three, enabling continuous at-sea deterrence. Its improved reactor, larger displacement (~7000 tonnes), and more launch tubes enhance strike capability.
Strategic significance:
- Strengthens nuclear triad, reducing vulnerability of land and air-based assets.
- Enhances deterrence credibility against nuclear adversaries like China and Pakistan.
Technological progress:
- Indigenous development involving DRDO and Indian shipyards reflects progress in nuclear propulsion, missile integration, and stealth capabilities.
- Ability to deploy longer-range K-4 SLBMs expands operational reach.
Challenges:
- Limited number of SSBNs compared to major powers like the US and China.
- High cost and technological complexity of nuclear submarines.
- Need for secure communication and command systems for underwater assets.
Policy and future plans:
- Expansion of SSBN fleet and parallel development of SSN (attack submarines).
- Leasing of nuclear submarines (e.g., from Russia) to bridge capability gaps.
- Strengthening naval infrastructure and maritime surveillance.
