India has successfully launched its fourth nuclear-powered ballistic missile submarine, S4, at the Ship-Building Centre in Visakhapatnam on October 16, 2024. This launch marks a significant leap in the nation’s naval capabilities, particularly in strengthening its nuclear deterrence strategy.
Features of the S4 Submarine:
- Indigenous Components: The S4 submarine is notable for its 75% indigenous components, reflecting India’s increasing self-reliance in defense manufacturing.
- Missile Capability: It is equipped with K-4 nuclear ballistic missiles, boasting a strike range of up to 3,500 kilometers. This is a major upgrade from the earlier K-15 missiles used in the INS Arihant-class submarines.
- Strategic Importance: The S4’s induction is a crucial step in enhancing India’s sea-based nuclear deterrence, especially in the context of rising regional tensions, particularly with China.
Context and Future Prospects: The S4 is part of a larger plan to boost India’s underwater warfare capabilities. After the commissioning of the INS Arighat in August 2024, the INS Aridhaman is expected to follow next year. In addition, the Indian government is moving forward with plans to build more nuclear-powered attack submarines to further strengthen its naval power.
This launch highlights India’s continued efforts to advance its military capabilities and maintain a credible nuclear deterrent in an increasingly complex geopolitical environment.
