The INS Arihant will be commissioned in the Indian Navy after extensive outfitting and sea trials. It is the first of three such vessels to be built in the country.
Gurshan Kaur unveiled a plaque naming the 112-metre-long submarine and said, "I name it INS Arihant. All the best to the submarine."
Declaring that India has achieved a 'historic milestone in the country's defence preparedness' with the launch of the submarine, Manmohan Singh said, "We don't have any aggressive designs nor do we seek to threaten anyone. We seek an external environment in our region and beyond that is conducive to our peaceful development and protection of our value systems."
