INS Arighat is the second Template:Sclass-.[7][8][9] It is the second nuclear-powered ballistic missile submarine being built by India.[10] It is being built under the Advanced Technology Vessel (ATV) project to build nuclear submarines at the Ship Building Centre in Visakhapatnam.[4] Arighat will have twice as many missile hatches as its predecessor INS Arihant, so it will be able to carry more missiles. It will also have a more powerful reactor than Arihant.[citation needed]

The submarine was originally assumed to be named INS Aridhaman, but when launched it was named INS Arighat.[1]

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][better source needed]

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 eight of the under-development K-4 missiles (with a range of 3,500 km or 2,200 mi).[13]

Status

Arighat 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.[4] 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] In October 2017, it was reported that she would be launched in November or December and would undergo outfitting.[15] The launch took place on 19 November.[1] Harbour trials and sea trials are expected to last for 2 years and commissioning is expected sometime in 2019.[16]
