Description

The boat will have one seven-blade propeller powered by a pressurised water reactor. 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.[12]

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 of the under-development K-4 missiles (with a range of 3,500 km or 2,200 mi).[3][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.[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] 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 2017.[3] The ship would undergo extensive sea trials for three years before being commissioned into the Indian Navy.[16] Arighat is expected to be commissioned in 2020.[3][17]
