Features of INS Arighat

It was laid down in 2011 under the Advanced Technology Vessel (ATV) project, and INS Arighat was launched in 2017.

INS Arighat is a 112-metre-long submarine, weighing around 6,000 tonnes and armed with K-15 Sagarika missiles that have a strike range of 750 km.

Like its forerunner INS Arihant, INS Arighat is also powered by 83 MW pressurised light-water reactors and can stay submerged for months on end, giving it an edge over conventional submarines.

Indian Navy's Arihant class submarines?

INS Arighat is the second in the Arihant-class submarines of the Indian Navy. The first nuclear-powered submarine INS Arihant was inducted in 2009. It was commissioned in August 2016 and deployed operationally in 2018.

The Indian nuclear-powered ballistic submarines have been named the Arihant class, which is a Sanskrit word meaning 'Destroyer of the Enemy.'

Among the many options considered, the name 'Arihant' was selected and approved at all levels because of its subtlety and appropriateness in conveying the resolve.

Only six countries have nuclear-powered submarines

With the Arihant-class submarines, India is part of an elite club of nations that have nuclear-powered submarines. Only six countries in the world—the United States, Russia, the United Kingdom, France, China, and India—have nuclear-powered submarines in their arsenal.

Advantages of nuclear-powered submarines

Nuclear-powered submarines have several advantages over traditional diesel-powered ones. This includes not having to resurface frequently for refuelling, allowing them to remain submerged for weeks or even months. They are also faster and can operate for up to 30 years. They are also stealthier than diesel-powered submarines and remain underwater undetected for much longer.
