INS Arighaat is an upgraded variant of the Arihant -class submarine .[ 9] [ 10] [ 11] It is the second nuclear-powered ballistic missile submarine made by India [ 12] under the Advanced Technology Vessel (ATV) project to build nuclear submarines at the Ship Building Centre in Visakhapatnam .[ 1] It has the code name S3 .[ 3] [ 13] [ 14]
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 Arighaat upon its launch. According to reports released in early 2021, she was to be commissioned in late 2021 alongside INS Vikrant .[ 15]
