INS Arighaat is an upgraded variant of the Arihant-class submarine. It is the second nuclear-powered ballistic missile submarine made by India under the Advanced Technology Vessel (ATV) project to build nuclear submarines at the Ship Building Centre in Visakhapatnam. It has the code name S3.
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.




Description


The boat will have one seven-blade propeller powered by a pressurised water reactor (PWR). It can achieve a maximum speed of 12–15 knots (22–28 km/h) when on surface and 24 knots (44 km/h) when submerged. The PWR is an upgraded form of the one that powers INS Arihant. The PWR has exceptionally lower acoustic signature than the previous generation making it harder to detect by enemy vessels along with longer endurance.
The submarine has four launch tubes in its hump, just like her predecessor. She can carry up to 12 K-15 Sagarika missiles (each with a range of 750 km or 470 mi), or four K-4 missiles (with a range of 3,500 km or 2,200 mi).




Status


INS Arighaat was launched in November 2017. INS Arighaat was expected to be commissioned in 2021. However the commissioning was pushed to 2024 as per a report in the Hindustan Times. INS Arighaat has been commissioned on 29 August 2024 after extensive trials and upgrades. The commissioning ceremony was held in the presence of Defence Minister Rajnath Singh in Naval Dockyard at Visakhapatnam.
INS Arighaat is significantly more advanced than the INS Arihant with an increased indigenous content of 70%. In contrast to its predecessor which is equipped with only 750-km range missiles, Arighaat is equipped with both K-15 Sagarika and K-4 missiles.
