New Delhi, April 3 India commissioned its third domestically-built nuclear-powered ballistic missile submarine, INS Aridaman, on Friday, significantly bolstering the nation's nuclear triad, authoritative sources said.
There has been no official announcement regarding the commissioning of the submarine, which comes amid a rapidly evolving regional security environment.
India's nuclear-powered ballistic missile submarine (SSBN) programme is a closely guarded project. INS Arihant was the first submarine under the SSBN project, followed by another, INS Arighat.
INS Arihant is India's first home-built nuclear submarine. It was launched in July 2009 and quietly commissioned in 2016. The navy commissioned its second indigenous SSBN, INS Arighaat, in August 2024. SSBN stands for ship-based ballistic nuclear or nuclear-powered ballistic missile submarines.
The SSBN programme is a key element of India's nuclear deterrence capability.
The induction of INS Aridaman is seen as a major milestone to enhance India's strategic strike capabilities.
India is among a select group of countries that possess nuclear-powered submarines. The countries that have such assets are the US, Russia, the UK, France, and China.
INS Aridaman was commissioned after months of sea trials. It is learned that Defence Minister Rajnath Singh and Navy Chief Admiral Dinesh K Tripathi attended the commissioning ceremony held at a frontline naval base in southern India.
"It's not just words, but power, 'Aridaman'," Singh said in a cryptic social media post in Hindi this morning.
While India has proven air and land-launched nuclear capabilities, it is now focusing on boosting its underwater nuclear prowess.
It is learned that the focus will now be on a fourth nuclear-powered submarine. While India has proven air and land-launched nuclear capabilities, it is now focusing on boosting its underwater nuclear prowess.
In December, Admiral Tripathi had confirmed that a new nuclear powered ballistic missile submarine will be commissioned into service soon.
India has been a leading voice in advocating for universal nuclear disarmament aimed at the complete elimination of atomic weapons.
In 1998, India conducted the Pokhran-II nuclear tests, triggering strong reactions from many countries.
Following the tests, India maintained that it carried them out to have a "credible minimum deterrence" and that it would follow the "no first use" policy.
In 2003, India officially came out with its nuclear doctrine that clearly elaborated on the "no first use" policy.
Earlier in the day, Indian Navy's new warship INS Taragiri was commissioned in the presence of Singh at Visakhapatnam.
In his address at the commissioning ceremony, Singh described INS Taragiri as not merely a warship but a symbol of India's growing technological prowess, self-reliance, and formidable naval power.
"This ship is capable of high-speed transit and can remain deployed at sea for extended periods. It is equipped with systems designed to monitor enemy movements, ensure its own security, and if necessary, deliver an immediate response," he said.
"It features modern radar, sonar, and missile systems, such as BrahMos and surface-to-air missiles, which further augment its operational prowess," he added.
