First Conventional Sub In 15 Years

Stealthy

The Kalvari is stealthier than nuclear subs as it can work without needing to surface or send up a snorkel for oxygen thanks to the use of Air-independent propulsion system found on the Scorpene subs that can help it stay underwater for up to 21 days at a stretch.

The system acts as a battery that runs the sub when it is submerged which in turns keeps down the noise the sub creates underwater. The diesel engines usually work while the sub is on the surface.

The Rebirth Of The Kalvari Name

The name Kalvari is taken from a deep sea tiger shark and is a revival of the name of India's first ever submarine, the INS Kalvari which was built by the Soviet Union in Leningrad (now St. Petersburg) in 1967.

The INS Kalvari was commissioned into the Indian Navy on 8 December 1967 and served the navy till it was decommissioned on 31 May, 1996.
