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.[18]
