India has been struggling to get a nuclear submarine in the water for some time. The technical challenges of "shrinking" a nuclear power plant to get one to fit on something the size of the submarine were daunting. On 26 July, 2009, India launched INS Arihant to gain them entry into the nuclear submarine club. That date might be the one asked about here, if something "exact" is being sought.
India launched its first Domesticaly built Nuclear Submarine July 26, 2009. It had been working with Russia since mid 2002 to lease a Akula Class Submarine.
As of October 2023, India has a total of 15 operational nuclear submarines, which include both ballistic missile submarines (SSBNs) and attack submarines (SSNs). The country operates four SSBNs, known as the Arihant-class, and is in the process of expanding its fleet. Additionally, India has several nuclear-powered attack submarines, enhancing its underwater capabilities. The exact number may vary as new submarines are commissioned or undergo maintenance.
From Wikipedia: Today, six countries deploy some form of nuclear-powered strategic submarines: the United States, Russia, France, the United Kingdom, People's Republic of China, and India Several other countries, including Argentina and Brazil, have ongoing projects in different phases to build nuclear-powered submarines.
The US, Russia, Great Britain, France, China and (recently) India have nuclear submarines.
India uses fossil fuels such as nuclear and coal.
As of October 2023, the countries known to possess nuclear submarines include the United States, Russia, China, France, and the United Kingdom. The United States has around 68 operational nuclear submarines, while Russia has approximately 60. China operates around 12, and both France and the United Kingdom have about 10 each. India is also developing its nuclear submarine capabilities and has launched its first operational vessel.
