First nuclear sub marine

India has become the sixth nation in the world to manufacture a nuclear submarine on its own. The nuclear sub marine was unveiled by our PM in Vishakhapatnam today. Formally the sub marine was given to the Indian Navy. Many people have said that this is a historic event. Many told that this is going to change the India’s naval strength to some high standards. India is a country which is surrounded by terrorist’s countries. So at this point of time, adding a nuclear sub marine to the naval has increased our naval security. This is indeed a historic event in India’s navy.
