India’s second indigenous nuclear submarine is likely to be launched in less than a month’s time, towards the end of September or the beginning of October, government sources said.
Launching of a boat refers to the process of transferring the vessel to the water from a dry dock. Once launched, the boat will undergo extensive sea trials before it is inducted in the Indian Navy some time in 2019.
The launch is likely to be done by Defence Minister Nirmala Sitharaman in keeping with the tradition that a boat is launched by a woman. The first indigenous nuclear submarine, INS Arihant, was launched in 2009 by former Prime Minister Manmohan Singh’s wife, Gursharan Kaur.
INS Arihant was quietly inducted in the Indian Navy in August 2016. It was the first nuclear attack submarine built by a country other than one of the five permanent members of the United Nations Security Council.
INS Aridhaman is the second Arihant-class submarine.She is the second nuclear-powered ballistic missile submarine being built by India. She is being built under the Advanced Technology Vessel (ATV) project to build nuclear submarines at the Ship Building Centre in Visakhapatnam. 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.
Aridhaman will have a seven-blade propeller powered by a pressurised water reactor and can achieve speed upto 12-15 knots on surface and 24 knots under water.
The boat will have a seven-blade propeller powered by a pressurised water reactor. She can achieve a maximum speed of 12–15 knots (22–28 km/h) on water surface and 24 knots (44 km/h) underwater.
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), or 8 of the under-development K-4 missiles (with a range of 3,500 km or 2,200 mi).
INS 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.
INS Arihant has four vertical launch tubes and can carry 12 K-15 missiles or four K-4 missiles.
The K-4 missile was developed as the Agni-III missile could not be deployed on INS Arihant due to space constraints.
