India’s Nuclear Submarine Projects

March 11/19: India leases Russian Submarine India signed a $3 billion contract for the lease of an Akula-1 class nuclear-powered attack submarine from Russia for a period of ten years. The submarine will be ready by 2025 and the contract includes refurbishment of the submarine with Indian communication and sensor systems, spares support and technical infrastructure for its operations. This submarine will replace INS Chakra, a submarine taken on a ten-year lease from Russia in 2012. The existing lease will be extended until the new submarine becomes operational. The so called Chakra III will not be equipped with long-range nuclear missiles because of international treaties and because it is not meant for deterrence patrols. In November last year, India’s first indigenous nuclear-powered submarine, INS Arihant, completed its first deterrence patrol. A second nuclear submarine, INS Arighat, will be commissioned later this year, with two more currently under construction.
