K-43 was a Charlie-class nuclear-powered cruise missile submarine operated by the Soviet and Indian navies. It was built between 1964 and 1967 and was commissioned into the Soviet navy on 5 November 1967. It later served as INS Chakra in the Indian Navy from 1988 to 1991.
It was leased to India on 1 September 1987 and reached its base in Visakhapatnam on 3 February 1988 after a long journey. The Soviets said that the submarine was transferred for helping train the Indian Navy in operating nuclear submarines. During its service with India, it was partially manned by a Soviet crew, who reportedly did not allow Indians into the missile room and into the reactor compartment and this is believed to be a reason for the termination of the contract after 3 years. The lease of Chakra reportedly helped India gain first-hand experience in handling a nuclear submarine that helped them build the Arihant class of nuclear submarines.
