Russian submarine Nerpa (K-152)

INS Chakra is a 8,140-tonne (8,010-long-ton) Project 971 (or Project 518; NATO: Akula-class submarine) nuclear-powered attack submarine. Construction was started in 1993, but 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. It was launched as K-152 Nerpa in October 2008 and entered service with the Russian Navy in late 2009. 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 4 April 2012. The INS Chakra joined the Eastern Naval Command at Visakhapatnam.
