‘Kalvari’, the first of the Scorpene class submarines, built at the Mazagon Dock Shipbuilders Ltd Mumbai (MDL).This important milestone was achieved by MDL after overcoming a number of challenges faced since launching of the submarine last year in October. 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. Thereafter she would be commissioned into the Indian Navy as INS Kalvari later this year. Commissioning of Kalvari will be a re-affirmation of India’s capability to build submarines and a major boost for the ‘Make in India’ programme of the government.

Operational Features

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

The Scorpene 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 i.e Anti-Surface warfare, Anti-Submarine warfare, Intelligence gathering, Mine Laying, Area Surveillance etc.
