INS Kalvari, the first of the Scorpene-class submarines, was commissioned by Prime Minister Narendra Modi. The war ship is the first of six such submarines that will be inducted into the Indian Navy. It represents a significant success for the Make in India initiative.
INS Kalvari, the first of the Scorpene-class submarines, was commissioned by Prime Minister Narendra Modi on 14 December 2017.
The commissioning ceremony was held at the Naval Dockyard in Mumbai, which was attended by Defence Minister Nirmala Sitharaman, Navy chief Admiral Sunil Lanba and top defence officials.
• The war ship is the first of six such submarines that will be inducted into the Indian Navy. It represents a significant success for the Make in India initiative.
• The submarines are being indigenously built by the Mazagaon Dockyard Ltd in Mumbai under Project 75 in collaboration with French industrial group DCNS.
• Kalvari, a diesel-electric attack submarine, is touted as India’s deadliest submarine and is expected to bolster India’s maritime prowess.
• The vessel had undergone around 120 days of extensive sea trials and tests for various equipments.
It is named after the first Foxtrot-class submarine Kalvari that was inducted into the Indian Navy on 8 December 1967.
It was decommissioned on 31 May 1996 after almost three decades of service.
About Scorpene-Class Submarines
• The submarines are designed by French naval defence and energy company DCNS and are being manufactured by Mazagon Dock Limited in Mumbai.
• India chose the Scorpene design in 2005, purchasing six submarines for US$3 billion under Project 75.
• The project was undertaken due to the decreasing number of submarines in the Indian Navy. The Navy required replacement for older Sindhughosh and Shishumar class submarines.
• The Scorpène class submarines have the capability to fire Exocet anti-ship missiles.
• India plans to incorporate the DRDO-developed air independent propulsion (AIP) system onto the last two submarines being built.
INS Kalvari- Special Features
• It is capable of offensive operations across the entire spectrum of naval warfare.
• It has a length of 67.5 metres and height of 12.3 metres. It also has an extremely silent Permanently Magnetised Propulsion Motor.
• The hull, fin and hydroplanes are designed for minimum underwater resistance and all equipment inside the pressure hull is mounted on shock absorbing cradles for enhanced stealth.
• The class is equipped with Weapons Launching tubes and these can carry weapons on board which can effectively be reloaded at sea.
• It is also equipped with 6 x 533-mm torpedo tubes for 18 heavy weight wire guided Surface and Underwater Target (SUT) torpedoes or Exocet Anti-ship missiles and 30 mines in place of torpedoes.
• The class is also fitted with mobile C303/S anti-torpedo decoys for self defence.
• The weapon systems and sensors are integrated with Submarine Tactical Integrated Combat System (SUBTICS).
• It also has a sonar system, which is capable of Low-Frequency Analysis and Ranging (LOFAR) enabling long range detection and classification.
The second Scorpene-class submarine, INS Khanderi, is currently undergoing trials and is likely to be inducted into the Navy soon.
