Indian Navy’s first indigenous Scorpene-class submarine, ‘Kalvari’ sailed out for first sea test on Sunday. Built under the much-delayed Project 75, Kalvari is the first of the India’s six Scorpene-class submarines built at the Mazagon Dock Shipbuilders Ltd for the Indian Navy.

A Navy official said, “The sea trials of Kalvari have begun on Sunday. It is a proud moment for us,”

Various preliminary tests on the propulsion system, auxiliary equipment and systems, navigation aids, communication equipment and steering gear, various standard operating procedures were approved for this new class of submarines. The submarine sailed out off the Mumbai coast at about 10 am under her own propulsion for her first sea trial.

The submarine, Kalvari will undergo a barrage of sea, surface, diving, weapons, noise trials, etc for testing her to the extremes over the next few months. Later this submarine will be commissioned into the Indian Navy giving a major strength to the ‘Make In India’ initiative of the government and Indian Navy as well.

This submarine was undocked on April 6, 2015 under Defense Minister Manohar Parrikar’s supervision. It underwent vacuum tests and battery loading at Naval Dockyard before returning to the MDL for completion of the basin trials and harbor acceptance trials phase.

The Scorpene submarines are specially designed to operate in all areas including the tropics, and encompass all means and communications to ensure interoperability with other components of a Naval Task Force. A high technology combat management system is required to manage the array of weapons and complex sensors fitted on board the Scorpene submarines.

Kalvari can undertake multilayered missions like anti-surface warfare, anti-submarine warfare, intelligence gathering, mine laying, area surveillance, etc.
