  • Named after the sand fish, a deep sea predator of the Indian Ocean
  • Diesel attack submarine, designed to perform sea denial as well as access denial warfare against the adversary
  • Enabled with a C303 anti-torpedo counter measure system
  • Superior stealth features include advanced acoustic absorption techniques, low radiated noise levels, hydro-dynamically optimised shape
  • Ability to launch a crippling attack using precision guided weapons, underwater or on surface


  • Envisages indigenous construction of six modern conventional submarines with contemporary equipment, weapons & sensors including Fuel-Cell based AIP (Air Independent Propulsion Plant), advanced torpedoes, modern missiles and state-of-the-art countermeasure systems
  • Progressively build indigenous capabilities in the private sector to design, develop and manufacture complex weapon systems for the future needs of the Armed Forces
  • Aid in boosting the core submarine/shipbuilding industry but would also greatly enhance the manufacturing/industrial sector, especially the Micro Small and Medium Enterprises (MSMEs) by developing an industrial ecosystem for the manufacture of associated spares/systems/equipment related to submarines.
  • The Kalvari class is a class of diesel-electric attack submarines based on the Scorpène-class submarine being built for the Indian Navy
  • The first of the Project – 75 submarines was commissioned into the Navy in 2017
