India is set to clear a mega indigenous project to build three nuclear-powered attack submarines, which will be followed by approval for another three at a later stage, as part of the long-term plan.
The overall project is for the construction of six nuclear-powered attack submarines (called SSNs in naval parlance), each weighing over 6,000-tonne, at the ship-building center (SBC) at Vizag.
But only three will be approved by the CCS in the first go, with the first indigenous SSN slated to roll out by around 2032 or so. Though each will cost around Rs 15,000 crore, the funding will not be a major problem because it will be spread over several years, said the sources.
