The First India’s Scorpene Class Submarine ‘Kalvari’ Gets Into Sea For Trails

‘Kalvari’, the first of Indian Scorpene class submarines, built at the Mazagon Dock Shipbuilders Mumbai (MDL), went to sea for the first time on 1 st May, as part of undergoing number of preliminary tests. These proceedings will continue for the next few months before to be commissioned into the Indian Navy as INS Kalvari later this year.

INS Kalvari


A number of number of preliminary tests on the propulsion system, Auxiliary Equipment and Systems, Navigation Aids, Communication Equipment and Steering gear. During the next few months, the submarine will undergo a barrage of sea trials, including surface trials, diving trials, weapon trials, Noise trials etc. which would test the submarine to the extremes of its intended operating envelop.

The statement has said that the Defense Minister in visited MDL plant in April 2015 and directed that all efforts to be made to complete the project in time. Accordingly, the teams from MDL, Indian Navy and DCNS have been working round the clock.

The Scorpene is equipped with Weapons Launching Tubes (WLT), and can carry weapons on board which can be easily reloaded at sea, through special handling and loading equipment. The array of weapons and complex sensors fitted on board the Scorpene are managed by a high technology Combat Management System, which integrates various diverse systems fitted onboard into One Formidable Whole.

Kalvari is the dreaded Tiger Shark, a deadly deep sea predator. As is the tradition, ships and submarines of the Navy, are brought alive after decommissioning. 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. In true nautical traditions, she will now be re-incarnated, by Mazagon Dock, once again a powerful predator of the deep, guarding the vast maritime interests and areas of our nation.

The commissioning of Yard 11875 (Kalvari),  will not only mark a generational shift in technology, insofar as submarine construction in India is concerned, but also for submarine operations by the Indian Navy.
