  • India’s first modern Conventional Submarine INS Kalvari Commissioned into Indian Navy Fleet.
  • The submarine can undertake multiple missions, including anti-surface warfare, anti-submarine warfare, intelligence gathering, mine laying and area surveillance.
  • The state-of-the-art technology in the submarine has superior stealth features such as advanced acoustic silencing techniques, low radiated noise levels, hydro-dynamically optimised shape and the ability to launch a crippling attack on the enemy using precision guided weapons, according to MDL.
  • The attack can be launched with both torpedoes and tube-launched anti-ship missiles, while underwater or on surface. The stealth of this potent platform is enhanced by the special attention given to various signatures. These stealth features give it invulnerability, unmatched by most submarines.

Kalvari is named after the dreaded tiger shark, a deadly deep sea predator of the Indian Ocean.

The second of the Scorpenes under construction at MDL, Khanderi, was launched in January 2017, and is currently undergoing the rigorous phase of sea trials. The third Scorpene, Karanj, is being readied for launch shortly. The remaining three submarines are in various stages of outfitting. The project is expected to be completed by 2020, MDL said.
