The Varunastra (Literally Projectile of Varuna) is an Indian advanced autonomous heavyweight anti-submarine torpedo, developed by the Naval Science and Technological Laboratory (NSTL) of the Defence Research and Development Organisation (DRDO) for the Indian Navy. It is named after a legendary weapon created by the Hindu god of the oceans, Varuna.[9]

The ship launched variant of Varunastra torpedo was formally inducted in the Indian navy by defence minister Manohar Parrikar on 26 June 2016.[1][10] The minister in his speech said that the Government is in favour of exporting the torpedo to friendly nations including Vietnam.[11][12] With some minor modifications the submarine variant of the torpedo is to be test fired shortly.[13]
