Navy inducts anti-submarine torpedo 'Varunastra'
Indigenously-built heavyweight anti-submarine torpedo 'Varunastra' was on Wednesday formally inducted into the Indian Navy, making India one of only eight countries to have the capability to design and build such a system. Developed by Naval Science and Technology Laboratory, it weighs around 1.25 tonnes and can carry 250 kg explosives. It's also capable of targeting quiet and stealthy submarines.
