INS Aridhaman Commissioned: The Nuclear Submarine Capability of India is Enhanced.

INS Aridhaman enters Indian Navy Fleet.

The Indian Navy has quietly commissioned INS Aridhaman, which is a major move in enhancing the Indian Navy in terms of maritime defence. The nuclear propulsion of this submarine boosts underwater deterrence of this country and strengthens strategic security system.

About INS Aridhaman

The third nuclear-powered ballistic missile submarine (SSBN) in India is INS Aridhaman (S4) and it belongs to the Arihant-class. Conceived as part of the Advanced Technology Vessel (ATV) programme, the submarines will be able to spend long durations at sea without detection due to their nuclear-capable missiles, being an essential component of Indian strategic deterrence.

Strategic Context Commissioning.

The submarine was commissioned on April 3 in Visakhapatnam in the presence of Rajnath Singh. The secretive nature of the nuclear submarine programme in India is indicated by the low profile ceremony. Its inception is at a period when growing attention is paid to maritime security in the Indo-Pacific region.

State-of-the-art Features and Capabilities.

INS Aridhaman is superior to its predecessor, INS Arihant and INS Arighaat. It is bigger, having a displacement of approximately 7,000 tonnes and is fitted with a better technology and better firepower. The submarine has the ability of carrying more nuclear missiles, making it more effective and strikeable.

Power of Deterrence and Missile Systems.

The submarine can launch nuclear-tipped missiles like the K-15 (Sagarika) and K-4 with a range of up to 3,500 km and future integration of longer-range systems like the K-5 missile is expected. These capabilities go a long way in enhancing the second-strike capability of India.

Exam-Focused Key Points

• INS Aridhaman (S4) is India’s third SSBN under the ATV programme.

• Part of Arihant-class nuclear submarines.

• Displacement: approx. 7,000 tonnes.

• Armed with K-15 and K-4 nuclear-tipped missiles.

• Improves the nuclear triad (land, air, sea-based deterrence) of India.

Future plans and strategic significance.

The second consolidation of nuclear triad with INS Aridhaman puts India in an elite club of countries with viable deterrence in the sea based on nuclear weapons. Another area that the Navy is developing is more submarines and nuclear-powered attack submarines (SSNs) to broaden its underwater reach in the next few decades.
