New Delhi. 29 June 2016. The anti-submarine torpedo Varunastra developed by Naval Science and Technological Laboratory of the DRDO for the Indian Navy became a part of the force today.
All uncertainties were put to rest which had arisen with the recent cancellation of a deal to procure Black Shark Heavyweight Torpedoes for both Kalavari class Diesel submarines and Nuclear Arihant class submarines, when the Minister for Defence Manohar Parrikkar handed over the made in India heavy weight torpedo Varunastra to the Indian Navy.
The first indigenous state-of -the-art heavy weight ship launched anti-submarine electric torpedo it is capable of targeting quiet and stealthy submarines, both in deep and littoral waters in intense countermeasure environment. This torpedo can achieve speeds in excess of 40 knots and is powered by an electric propulsion system with multiple 250 KWs Silver Oxide Zinc (AgOZn) batteries. Varunastra had completed user trials and was to be inducted into the Indian Navy in March 2016. But keeping in mind DRDO’s track record three months delay is not bad at all.

Varunastra has been designed with latest technologies such as high speed and long endurance propulsion, software driven intelligence, conformal array acoustic homing with wide look angle and advanced digital signal processing. It is also having advanced autonomous guidance algorithms with low drift navigational aids, insensitive warhead which can operate in various combat scenarios. Varunastra exercise variant has integrated instrumentation system for recording all the dynamic parameters of the weapon, redundancy in recovery aids in case of emergency shut down or malfunction.

It has GPS based locating aid, a unique feature in contemporary torpedoes in the world. Varunastra is extensively tested at sea in association with Indian Navy for evaluating the weapon capabilities as per Naval Staff qualitative requirements. The weapon has completed all environmental qualification tests like shock, vibration, temperature cycling, marine environmental tests, EMI/EMC tests etc.
