  • On September 21st, 2017, the country’s first indigenously built Scorpene-class submarine Kalvari handed over to the Indian Navy.
  • Kalvari is the dreaded Tiger Shark, a deadly deep sea predator.
  • The submarine was built by the Mazagaon Docks Limited (MDL) at Mumbai.
  • As part of the project, MDL will build a total of six submarines and Kalvari is the first one.
  • These Scorpene submarines are being built under Project 75.
  • The state-of-art features of the Scorpene include superior stealth and the ability to launch a crippling attack on the enemy using precision guided weapons.
  • The attack can be launched with torpedoes, as well as tube launched anti-ship missiles, whilst underwater or on surface.
  • It can be operated in all seasons.
  • This submarine is capable of carrying out various types of missions.
  • These include anti-submarine warfare, anti-surface warfare information collection, field monitoring etc.
  • ‘Kalwari’ is built from special steel, capable of withstanding high yield stress and having high tensile strength, thereby allowing them to withstand high hydrostatic force and enabling them to dive deeper to further enhance stealth.
  • The ongoing project for the construction of six Scorpene class submarines has M/s DCNS of France, as Collaborator and includes ‘Transfer of Technology’, with M/s MDL as the ‘Builder’.
  • The cost of Scorpion submarines developed under Project-75 is approximately 3.5 billion dollars.
  • The first Kalvari, which was also the first Indian submarine, was commissioned into the Indian Navy on 08 December 1967. She was decommissioned on 31 May 1996 after almost 30 years of yeoman service to the nation.
