India will acquire on lease a second nuclear submarine from Russia possibly during Prime Minister Manmohan Singh\'s visit to Moscow starting on Sunday, said Press Trust of India. The move comes two months after the Indian Navy\'s Russian-made Kilo Class INS Sindhurakshak submarine exploded and sank at the Mumbai harbor. The Indian Navy has only a rented nuclear submarine from Russia, while the country is expected soon to produce an aboriginal nuclear submarine, whose power system has been activated two months ago.
