Submarine INS Kalvari, commissioned into the Indian Navy in December 2017, was built with technological collaboration with France. It is the first of the Scorpene-class submarines built in India.
– The Scorpene class (Project 75) submarines are designed by French naval defence and energy group Naval Group (formerly DCNS).
– These submarines are being built in India by Mazagon Dock Shipbuilders Limited (MDL) in Mumbai through a transfer of technology.
– The technological know-how and design are primarily from France.
INS Kalvari is the lead boat of six Scorpene-class submarines planned for the Indian Navy under Project 75. The other submarines are Khanderi, Karanj, Vela, Vagir, and Vagsheer. The project is a significant step towards indigenization in submarine construction.
