INS Aridhaman is the second Arihant-class submarine.[7][8][9] She is the second nuclear-powered ballistic missile submarine being built by India.[10] She is being built under the Advanced Technology Vessel (ATV) project to build nuclear submarines at the Ship Building Centre in Visakhapatnam.[1] This submarine will have double the number of missile hatches than its predecessor INS Arihant giving it the ability to carry more missiles. This will have a more powerful reactor than its predecessor.

Description

The boat will have one seven-blade propeller powered by a pressurised water reactor. She can achieve a maximum speed of 12–15 knots (22–28 km/h) when on surface and 24 knots (44 km/h) when submerged.[11]

The submarine has eight launch tubes in its hump. She can carry up to 24 K-15 Sagarika missiles (each with a range of 750 km or 470 mi),[12] or 8 of the under-development K-4 missiles (with a range of 3,500 km or 2,200 mi).[13]

Aridhaman will be fitted with the sonar ISS (Integrated Sonar Suite), state-of-the-art sonar developed by NPOL DRDO. It is a unified submarine sonar and tactical control system, which includes all types of sonar (passive, surveillance, ranging, intercept, obstacle avoidance and active). It also features an underwater communications system. The hull features twin flank-array sonars and Rafael broadband expendable anti-torpedo countermeasures.

Status

Aridhaman is being built in Visakhapatnam. She is currently being outfitted. In January 2012, it was announced that she would be launched in late 2012 or early 2013.[1] In December 2014 it was reported that work on the second nuclear sub reactor had begun and possibly by early 2016 she will be launched.[14][15]In December 2015 a report published in defencenews.in claimed that India's second nuclear submarine INS Aridhaman is being readied for launch as her elder sibling INS Arihant is being readied for commissioning."As soon as the Arihant is commissioned the focus will be on the second submarine.The hull fabrication of the third Arihant-class submarine has also been completed.If everything goes as per schedule , INS Aridhaman after clearing trials will join the Indian Navy by 2018-end ",said a navy source.[16]
