Three hundred Indian Navy personnel were trained in Russia for the operation of the Akula II submarine ''Nerpa''. [[India]] has finalised a deal with Russia, in which at the end of the lease of these submarines, it has an option to buy them. The submarine is named [[Russian submarine K-152 Nerpa|INS ''Chakra'']] as was the previous India-leased Soviet Charlie-I SSGN.<ref>{{cite web |url=http://indiatoday.digitaltoday.in/index.php?option=com_content&task=view&id=10800&issueid=67 |title=India to get Russian nuclear submarine after 17 years |date=3 July 2008 |website=[[India Today]] |access-date=19 December 2014 |archive-url=https://web.archive.org/web/20081222024636/http://indiatoday.digitaltoday.in/index.php?option=com_content&task=view&id=10800&issueid=67 |archive-date=22 December 2008 |url-status=dead}}</ref> ''Chakra'' was officially commissioned into the Indian Navy on 4 April 2012.<ref>{{cite news |url=http://economictimes.indiatimes.com/news/politics/nation/ins-chakra-govt-inducts-8000-ton-russian-origin-akula-ii-class-nerpa-into-navy/articleshow/12526102.cms |title=INS Chakra: Govt inducts Russian-origin Akula II class Nerpa into Navy |newspaper=[[The Economic Times]] |date=2012-04-04 |access-date=2012-10-04 |archive-url=https://web.archive.org/web/20120407070809/http://economictimes.indiatimes.com/news/politics/nation/ins-chakra-govt-inducts-8000-ton-russian-origin-akula-ii-class-nerpa-into-navy/articleshow/12526102.cms |archive-date=2012-04-07 |url-status=live}}</ref><ref>{{cite web |url=http://indiatoday.intoday.in/story/ins-chakra-inducted-into-indian-navy/1/182955.html |title=INS Chakra formally inducted into Indian Navy |website=India Today |date=2012-04-04 |access-date=2012-10-04 |archive-url=https://web.archive.org/web/20120919152021/http://indiatoday.intoday.in/story/ins-chakra-inducted-into-indian-navy/1/182955.html |archive-date=2012-09-19 |url-status=live}}</ref>

Whereas the Russian Navy's Akula-II could be equipped with 28 nuclear-capable cruise missiles with a striking range of {{convert|3000|km|nmi mi|0|abbr=on}}, the Indian version is reportedly armed with the {{convert|300|km|nmi mi|0|abbr=on}}-range [[3M-54 Klub|Club-S]] nuclear-capable missiles.<!-- [Footnote does NOT contain any information included in the previous sentence.] --><ref>{{cite news |url=http://www.hindu.com/2006/07/01/stories/2006070118091800.htm |title=Russia may lease nuclear submarine to India |date=1 July 2006 |access-date=1 July 2006 |newspaper=[[The Hindu]] |archive-url=https://web.archive.org/web/20060717105158/http://www.hindu.com/2006/07/01/stories/2006070118091800.htm |archive-date=17 July 2006 |url-status=dead}}</ref> Missiles with ranges greater than {{convert|300|km|nmi mi|0|abbr=on}} cannot be exported due to arms control restrictions, since Russia is a signatory to the [[Missile Technology Control Regime|MTCR treaty]].

In June 2021, ''Nerpa'' was reported in Singapore with Indian crew aboard and on its way back to Russia, despite one year remaining of the 10-year lease, commenced in April 2012. The stated reason was problems with maintenance of the nuclear reactors. Accordingly, the lease will not be prolonged after 2022, as was initially expected.<ref name="tass.ru" />
