INS Arihant

INS Arihant is the first of the planned five in the class of submarines designed and constructed as a part of the Indian Navy's secretive Advanced Technology Vessel (ATV) project. The ATV project was set up in 1984, under Vice Admiral Mihir K. Roy as the first Director General. The {{sclass|Arihant|submarine|4}} submarines are reported to be based on the {{sclass|Akula|submarine}}.{{cite web |url=http://www.naval-technology.com/projects/arihant-class/ |title=SSBN Arihant Class Submarine, India |publisher=naval-technology.com |access-date=2 June 2015 |archive-url=https://web.archive.org/web/20130502115614/http://www.naval-technology.com/projects/arihant-class |archive-date=2 May 2013 |url-status=live }} Their crew were to have the opportunity to train on INS Chakra, an Akula-class submarine, which the Indian Navy leased from Russia.{{cite web|url=http://www.globalsecurity.org/military/world/india/atv.htm|title=Arihant – Advanced Technology Vessel (ATV)|publisher=Global Security|access-date=2 June 2015|archive-url=https://web.archive.org/web/20101226032637/http://www.globalsecurity.org/military/world/india/atv.htm|archive-date=26 December 2010|url-status=live}}{{cite news|url=http://indiatoday.intoday.in/story/leased-russian-n-submarine-to-set-sail-for-india-this-month-end/1/164449.html|title=Leased Russian n-submarine to set sail for India this month end|work=indiatoday|date=15 December 2011|access-date=2 June 2015|archive-url=https://web.archive.org/web/20120105102758/http://indiatoday.intoday.in/story/leased-russian-n-submarine-to-set-sail-for-india-this-month-end/1/164449.html|archive-date=5 January 2012|url-status=live}} Arihant is intended to be more of "a technology demonstrator" than a fully operational SSBN according to Admiral Nirmal Verma.{{cite news|url=https://timesofindia.indiatimes.com/india/Home-made-nuke-sub-INS-Arihant-to-be-inducted-in-2-years/articleshow/5293123.cms|title=Home-made nuke sub INS Arihant to be inducted in 2 years|last=Pandit|first=Rajat|date=3 December 2009|access-date=2 June 2015|archive-url=https://web.archive.org/web/20160613034034/http://www.newindianexpress.com/nation/EXPRESS-EXCLUSIVE-Maiden-Test-of-Undersea-K-4-Missile-From-Arihant-Submarine/2016/04/09/article3370608.ece|archive-date=13 June 2016|work=The Times of India|url-status=live}}
