First Production Varunastra Heavyweight Torpedo Delivered to the Indian Navy

The first production torpedo left the BDL factory on 21 November 2020. The Varunastra was developed by Naval Science and Technological Laboratory (NSTL) of the Defence Research and Development Organisation (DRDO) for the Indian Navy.

The Varunastra (Sanskrit वरुणास्त्र) is the water weapon (a storm) according to the Indian scriptures, incepted by Varuna, god of hydrosphere. In stories, it is said to assume any weapon’s shape, just like water. Upon usage, it brings large volume of water which washes away large part of infantry.

BDL obtained a DRDO license to manufacture Varunastra in April 2018. In June 2019, the Indian Ministry of Defence awarded a contract worth ₹1,187 crore (US$170 million) to the company to mass produce the torpedo for the Indian Navy.

The torpedo is powered by an electric propulsion system with multiple 250 KWs Silver Oxide Zinc (AgOZn) batteries. It has a maximum speed of 40 knots, a range of 21.6 nautical miles and can dive to 400 meters. Like most modern torpedoes, it is wire-guided with active-passive acoustic homing. According to local media reports, it features GPS guidance as well.
