The Government of India approved the construction of six new nuclear powered [[Engineering:Attack submarine|attack submarines]] (SSN)<ref name=":0">{{cite news|title=India to Build 6 Nuclear-Powered Submarines - Navy Chief|url=https://sputniknews.com/military/201512041031242059-india-submarine-nuclear-fleet/|work=Sputnik International|agency=Sputnik|date=4 December 2015}}</ref> in February 2015.<ref>{{cite news |url=http://articles.economictimes.indiatimes.com/2015-02-18/news/59268906_1_submarines-frigates-indian-ocean-region |title=Government clears construction of 7 stealth frigates, 6 nuclear-powered attack submarines |newspaper=The Economic Times |date=18 February 2015 |accessdate=19 April 2015}}</ref> These will be designed by the Navy's in-house Directorate of Naval Design and indigenously built in the Shipbuilding Center at Visakhapatnam.

==Development==
According to ''India Today'', a patrol by a {{sclass-|Shang|submarine}} in the Indian Ocean prompted the revival of a plan to build six nuclear-powered attack submarines.<ref>{{cite news|url=https://www.indiatoday.in/magazine/the-big-story/story/20171218-india-ballistic-missile-submarine-k-6-submarine-launched-drdo-1102085-2017-12-10|title=A peek into India's top secret and costliest defence project, nuclear submarines|last1=Unnithan|first1=Sandeep|date=10 December 2017|work=India Today|access-date=|url-status=live|archive-url=https://web.archive.org/web/20190420153439/https://www.indiatoday.in/magazine/the-big-story/story/20171218-india-ballistic-missile-submarine-k-6-submarine-launched-drdo-1102085-2017-12-10|archive-date=20 April 2019|language=en}}</ref>

The submarines will be powered by a miniature [[Engineering:Pressurized water reactor|pressurized water reactor]] (PWR) being developed by the [[Organization:Bhabha Atomic Research Centre|Bhabha Atomic Research Centre]] which has already supplied a similar 83 MW miniature reactor for the [[Engineering:Arihant-class submarine|Arihant-class submarine]] SSBNs.<ref name=natinterest/>

On 24 June 2019, it was reported that {{INRConvert|100|c}} have been allocated for the initial phase of the project. The submarines will be designed by Directorate of Naval Design and the development is expected to continue till 2025. Mishra Dhatu Nigam is developing a new hull material that is expected to allow the submarine to dive to deeper depths than {{sclass-|Arihant|submarine|4}}. A scaled down model of the submarine is planned to be tested first. The total cost of the project is estimated to be around {{INRConvert|1|lc}}.<ref>{{Cite news|url=https://economictimes.indiatimes.com/news/defence/work-begins-on-indias-next-gen-nuclear-powered-submarines/articleshow/69921014.cms|title=Work begins on India’s next gen nuclear-powered submarines|last=Pubby|first=Manu|date=2019-06-24|work=The Economic Times|access-date=2019-07-02|url-status=live|archive-url=https://web.archive.org/web/20190624164324/https://economictimes.indiatimes.com/news/defence/work-begins-on-indias-next-gen-nuclear-powered-submarines/articleshow/69921014.cms|archive-date=24 June 2019}}</ref>

In February 2020, ''The Economic Times'' reported that the preliminary design phase of the programme has been successfully completed. The report stated that Submarine Design Group of the Directorate of Naval Design, assisted by DRDO, will now start working on the detailed design and construction phase of the programme.<ref name="ETfeb2020">{{Cite news|last=Pubby|first=Manu|url=https://economictimes.indiatimes.com/news/defence/indias-rs-1-2-l-cr-n-submarine-project-closer-to-realisation/articleshow/74234776.cms|title=India’s Rs 1.2 lakh crore nuclear submarine project closer to realisation|date=2020-02-21|work=The Economic Times|access-date=2020-02-23}}</ref>
