The Defence Research and Development Organisation’s Naval Science and Technological Laboratory (NSTL) is advancing an upgraded Lightweight Torpedo, enhancing speed and endurance while retaining a 25 km operational range. This next-generation torpedo, designed for the Indian Navy’s anti-submarine warfare capabilities, aims for a 42% increase in underwater speed, potentially reaching 47 knots, through advanced propulsion and battery technologies. As the Indian Navy faces evolving maritime threats, particularly from China’s advanced submarines, the upgraded torpedo will bolster its operational readiness. NSTL’s focus on indigenous development supports India’s self-reliance strategy and aims to attract export opportunities, particularly in the Indo-Pacific region, while fostering job creation and technological advancements through local production partnerships.
