INS Aridhaman Nuclear Submarine Joins Indian Navy Fleet

India has taken another strong step in boosting its defense power with the silent commissioning of its third nuclear-powered submarine, INS Aridhaman. The ceremony was kept low-key, but it marks an important moment for the country’s naval strength and security.

What is INS Aridhaman?

INS Aridhaman (S4) is India’s third nuclear-powered ballistic missile submarine (SSBN). These submarines are specially designed to carry nuclear missiles  and stay hidden underwater for long periods.

It belongs to the Arihant-class submarines, which are developed as part of India’s secret Advanced Technology Vessel (ATV) programme.

Quiet Commissioning in Visakhapatnam

The submarine was officially commissioned on April 3 in Visakhapatnam in the presence of Defence Minister Rajnath Singh.

The event was not publicly announced, but the minister hinted at it through a short message on social media, calling the submarine a symbol of power. The timing of the ceremony matched his visit for another naval event.

Stronger and Bigger than Before

INS Aridhaman is more advanced than the earlier submarines INS Arihant and INS Arighaat.

• It is larger, weighing around 7,000 tonnes.
• It has better technology and higher firepower.
• It can carry more nuclear missiles.

This makes it a more powerful addition to India’s naval forces.

Powerful Missile Capabilities

INS Aridhaman can carry different types of nuclear-capable missiles, such as:

• K-15 Sagarika missiles
• K-4 missiles (range around 3,500 km)
• Future K-5 missiles

It can carry more missiles than earlier submarines, increasing India’s strike capability from the sea.

Part of India’s Nuclear Triad

With this submarine, India further strengthens its nuclear triad. This means the country can launch nuclear weapons from:

• Land
• Air
• Sea

Only a few countries like the United States, Russia, China and France have their capability, placing India among the top military powers in the world.

Future Plans of the Indian Navy

India is not stopping here. The Navy is already working on:

• Another similar submarines, currently under trials.
• Nuclear-powered attack submarines (SSNs)
• Plans to commission more submarines by 2036-39.

These steps aim to make India’s navy stronger and more self-reliant.
