The INS Aridhaman is the second ballistic missile submarine India will have constructed once she begins sea trials, which could take at least a year. She is powered by a pressurized water reactor, a common nuclear energy generator used in the subs of nations as the US, Russia, and France, sputniknews.com
The reactor intakes water, pumps it to the reactor’s core where it is heated by fission reactions, and then funnels the hot water to a second system, a steam generator. The generator uses the steam from the water to spin a turbine which then spins an electric generator.
INS Aridhaman will start sea trials under the watch of Defense Minister Nirmala Sitharaman, India Times reported. Compared to INS Arinhat, Aridhaman can carry twice as many missiles and is expected to cruise faster underwater as a result of a more powerful propulsion system.
Aridhaman’s hull was laid in 2011 in the coastal city of Visakhapatnam.
