The submarine was quietly launched in 2017 and little has been publicly announced about its capabilities and current status. The submarine was originally known as INS ''Aridhaman'' but was renamed INS ''Arighat'' upon its launch. According to reports released in early 2021, she was to be commissioned in late 2021 alongside [[INS Vikrant (2013)|INS ''Vikrant'']].<ref name="HTMarch21"/>

== Description ==
The boat will have one seven-blade propeller powered by a [[pressurised water reactor]]. It can achieve a maximum speed of {{convert|12|-|15|kn|km/h}} when on surface and {{convert|24|kn|km/h}} when submerged.<ref name="navaltech">{{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 2013}}</ref>{{Better source|reason=Blacklisted|date=December 2017}}

The submarine has four launch tubes in its hump, just like her predecessor. She can carry up to 12 [[Sagarika (missile)|K-15 Sagarika]] missiles (each with a range of {{convert|750|km|abbr=on|disp=or}}), or four of the under-development [[K-4 (SLBM)|K-4 missiles]] (with a range of {{convert|3500|km|abbr=on|disp=or}}).<ref name="launched"/><ref>{{Cite web|url=https://www.indiatoday.in/india/story/ins-arihant-returned-yesterday-from-20-day-deterrent-patrol-1383188-2018-11-05|title=INS Arihant returned yesterday from 20-day deterrent patrol|date=5 November 2018|website=India Today|language=en|access-date=2019-10-13}}</ref>
