INS Kalvari: India’s first home built Scorpene submarine handed over to Indian Navy


INS Kalvari, the first of the six Scorpene-class submarines built in India under the initiative of Make-in-India programme has been delivered to the Navy. The submarine was built by the Mazgaon Docks Limited (MDL) as part of technology was transferred from France. Kalvari is named after the dreaded Tiger Shark, a deadly deep sea predator of the Indian Ocean. The submarines, designed by French naval defence and energy company DCNS, are being built by Mazagon Dock Ltd in Mumbai as part of Project-75 of the Indian Navy.

This Scorpene submarine is designed to operate in all theatres of war, including the tropics. Kalvari is capable of handling various missions such as anti-surface warfare (attacking surface ships), anti-submarine warfare (destroying submarines), intelligence gathering, mine-laying and area surveillance.

The Kalvari was built with a special kind of high-tensile steel that is capable of withstanding high yield stress. This feature allows it to withstand pressure exerted by water, hydrostatic force, while diving deeper to enhance stealth. It is also capable of carrying weapons that can be easily reloaded at sea.

The second of the Scorpenes under construction, Khanderi, was launched in January 2017 and it is currently undergoing rigorous phase of sea trials. The third Scorpene, Karanj, is being readied for launch later this year. The remaining submarines are likely to be delivered to the navy by 2020.
