India has launched its first domestically-built nuclear-powered submarine.
The submarine launched for sea trials at the southern port city of Vishakhapatnam Sunday is called the Arihant, or "Destroyer of Enemies." But Prime Minister Manmohan Singh says India does not have any "aggressive designs" or seek to threaten anyone. He says the sea is becoming increasingly relevant to India's security interests.
Once in service, the 6,000-ton submarine will be capable of firing ballistic missiles with nuclear warheads.It will go through at least two years of trials before becoming fully operational with a 100-man crew. The vessel was built with technical assistance from Russia and is the first of five submarines New Delhi plans to build. India now joins five other nations that have built nuclear submarines. The others are the United States, China, Britain, France and Russia.
