INS Kalvari Current Affairs

INS Kalvari: First Scorpene-class submarines inducted in Indian Navy

Prime Minister Narendra Modi has commissioned scorpene-class submarine INS Kalvari into the Indian Navy in Mumbai, Maharashtra. It is first of the six Scorpene-class submarines built under the strategic Project 75 built by Mazagon Dock Limited (MDL) with assistance and technology transfer from France’s DCNS. The commissioning comes days after Indian Navy observed the golden jubilee of its submarine wing.

INS Kalvari will be the first conventional submarine to be inducted into India Navy after more than 17 years. INS Sindhushastra was last inducted conventional diesel-electric submarine in July 2000 which was procured from Russia.

INS Kalvari

INS Kalvari is most modern non-nuclear stealth submarine in India Navy. ‘Kalvari’ is Malayalam word that means deep-sea tiger shark. It reflects its agility, strength and predatory prowess. The length of INS Kalvari is 67.5 metres and height of 12.3 metres and weighs 1,565-tonn and displacement capacity of 1,600 tonnes.

It is powered by two 1250 kW MAN extremely silent diesel-electric diesel engines making it very difficult to detect underwater. It boasts highly advanced Combat Management System and a sophisticated Integrated Platform Management System.

Its hull form, fin and hydroplanes are specifically designed to produce minimum underwater resistance. It has 360 battery cells (each weighing 750 kg) to power the extremely silent Permanently Magnetised Propulsion Motor. Its stealth capability is enhanced through mounting of equipment inside pressure hull on shock absorbing cradles.

Submarine Tactical Integrated Combat System (SUBTICS) suite is heart of INS Kalvari’s weapons system which processes information from sonars on-board submarine in detecting targets which can then be engaged with torpedoes or missiles.

It is armed with heavy weight torpedoes and Exocet anti-ship missiles. It can launch torpedoes both while submerged or on the surface. It has an attack-and-search periscope equipped with infrared and low light level cameras and laser range finders to spot targets on the surface of the sea.

It is designed to operate in all theatres, including the tropics and can undertake multifarious types of missions typically undertaken by any modern submarine such as anti-submarine warfare, anti-surface warfare, intelligence gathering, area surveillance, mine laying etc.

Second Scorpene Class Submarine Ready for Sea Trials

Defence Minister Arun Jaitley has announced that the second Scorpene-class submarine is ready for surface sea trials. INS Khanderi, the second Scorpene class submarine has been built at Mazagon Dock Limited (MDL) in Mumbai, Maharashtra.  It is the second of the six submarines being built at MDL in collaboration with France’s DCNS as part of Project 75 of Indian Navy.

Salient Highlights

INS Khanderi has been named Khanderi, after the Island fort of Maratha ruler Chhatrapati Shivaji which played had vital role in ensuring their supremacy at sea in late 17th century. Khanderi is also name for Tiger Shark.

The state-of-the-art features in the submarine include superior stealth and ability to launch a crippling attack on the enemy using precision guided weapon. The attack from it can be launched with torpedoes, as well as tube-launched anti-ship missiles, whilst on surface or underwater. The stealth features gives it invulnerability, unmatched by many submarines.

The submarine is designed to operate in all theatres, including the tropics. All means and communications are provided to ensure interoperability with other components of a Naval task force. It can undertake multifarious types of missions typically undertaken by any modern submarine such as anti-submarine warfare, anti-surface warfare, intelligence gathering, area surveillance, mine laying etc.

In general, the Scorpene-class submarines are expected to significantly enhance India’s naval power and strength while making the country ocean safe and secure.

Project 75

Under Project 75 India will construct 6 next generation diesel submarines with Air Independent Propulsion System (AIP) technology for the Indian Navy by 2022. The project is built with assistance and technology transfer from DCNS of France under deal signed in October 2005. The first of the series INS Kalvari is completing sea trials and will be commissioned shortly. The other four submarines are expected to be launched at nine-month intervals after the INS Khanderi.
