India activates atomic reactor for its indigenously built nuclear submarine

NEW DELHI — India on Saturday activated the atomic reactor onboard its first indigenously designed and built nuclear submarine, paving the way for its deployment by the navy in the next two years.

Prime Minister Manmohan Singh said the development represented a giant stride in the progress of India's indigenous technological capabilities.

The vessel is the first ballistic missile submarine to be built outside the five recognized nuclear powers — the United States, France, Russia, Britain and China.

Rahul Bedi, an analyst for the independent Jane's Information Group, said the submarine would now undergo sea trials. The vessel has been undergoing harbor trials in eastern India.
