he first made-in-India nuclear-powered submarine INS Arihant started sea trials at Vizag today.
According to the Naval sources, INS Arihant kick-started its maiden sea trial from the Shipbuilding Centre, Visakhapatnam today. Huge preparations were done to ensure a smooth sail out for the 6,000-tonne nuclear powered ballistic missile submarine (SSBN).INS Arihant is longer than any of the submarine in the Indian Navy`s fleet so far. A nuclear submarine is powered by a nuclear reactor, which generates tremendous heat driving a steam turbine. It has unlimited underwater endurance and speed twice that of its conventional counterparts.
The INS Arihant's miniaturised nuclear reactor, built with Russian help, had gone critical last year and the vessel has been going through a series of harbour trials since then at Visakhapatnam, where it is being built.
