The Indian Navy aims to procure new nuclear-powered attack submarines under Project 75 Alpha.[2] The Government of India approved the construction of six of such submarines in February 2015.[3] These will be designed by the Navy's in-house Directorate of Naval Design and built in India at the Shipbuilding Centre at Visakhapatnam. The construction is expected to commence on 2023-24 while the first submarine is expected to enter service in 2052.
Since India is a traditional user of Russian nuclear submarines (with INS Chakra on lease) the new domestically built submarines would be third class of SSN operated by Indian navy after leased Charlie I and Akula II-class submarines.[4][5]
