INS Chakra is a 8,140-tonne nuclear-powered attack submarine. Originally known as the Nerpa submarine, it's construction was started in 1993, but was then suspended due to lack of funding. The Indian Navy sponsored the building and sea trials of the submarine provided it was given to the Indian Navy on lease for 10 years. The submarine was leased to the Indian Navy in 2011 after extensive trials, and was formally commissioned into service as INS Chakra II at a ceremony in Visakhapatnam on 4th April 2012.
