That leap for India’s ballistic nuclear submarine capabilities would come with the fourth submarine planned in the same class, named S4-Star. It would have a stronger weapons configuration integrated into an extra compartment that would be added to Arihant’s original design.
On the Aridhaman, sources said the “final checks are under way. All the three modules have been integrated. It is likely to be launched in late November,” an official source told The Hindu. Another source said a November launch may be difficult, but “in December, it will definitely be in the sea.”
Fuel loading in the nuclear reactor for Aridhaman was completed in January, but it would go critical only much later after initial sea trials. Once launched, the submarine will be put to extensive harbour and sea trials, before being formally commissioned in the next couple of years.
The indigenously built second nuclear submarine will add to India’s growing nuclear capabilities, in the face of the new strategic realities of the region, including the assertive Chinese naval presence in the Indian Ocean.
Last October, India commissioned its first Ballistic Nuclear Submarine, INS Arihant. The vessel, weighing 6,000 tonnes, is powered by an 83 MW pressurised light water nuclear reactor.
Aridhaman, of the Arihant class, will carry several new pieces of equipment including new-generation sensors and periscope, compared to the first ship.
Construction of the third submarine of the same class is under way in four different parts, and could be completed approximately in a year. This would also be of the same size as Arihant and Aridhaman, but possess more advanced weapons and sensors. The third submarine is planned for launch in late 2018.
As soon as Aridhaman is launched, the final integration of the third submarine will begin in Visakhapatnam, it is learnt.
Indigenous capability
The project to build a strategic nuclear submarine to carry nuclear missiles began as the Advanced Technology Vessel project in the 1980s, and the vessel project was launched in 2009 by Dr. Manmohan Singh.
Arihant, which can carry nuclear tipped ballistic missiles, is of the ship submersible ballistic nuclear class.
