In a significant stride towards enhancing India’s naval capabilities, the Defence Research and Development Organisation (DRDO) has developed the Electronic Heavy Weight Torpedo (EHWT), a cutting-edge weapon system designed to bolster the Indian Navy’s underwater combat prowess. This development marks a pivotal moment in India’s defense autonomy, aligning with the national vision of ‘Aatmanirbhar Bharat’ or self-reliant India.
The EHWT is an advanced, submarine-launched anti-submarine warfare (ASW) torpedo. It is an evolution of the previously inducted Varunastra torpedo, tailored specifically for submarine deployment. This torpedo is designed to engage quiet submarines effectively in both shallow and deep waters, showcasing a blend of high precision and significant range capabilities.
Unlike traditional torpedoes that might use gas turbines or other fuel-based propulsion, EHWT employs an electric propulsion system. This reduces its acoustic signature, making it stealthier and harder to detect by enemy sonar. The torpedo is equipped with advanced autonomous guidance algorithms, enhancing its ability to pursue and engage targets even in complex underwater environments.
ith an operational range extending to about 40 kilometers and a speed of around 40 knots, EHWT can cover vast swathes of ocean quickly, providing a strategic advantage in naval engagements. It can operate at depths up to 600 meters, allowing it to reach and neutralize threats at various depth levels.
The EHWT carries a substantial warhead, ensuring significant destructive power upon impact, crucial in naval combat scenarios. Developed by the Naval Science and Technological Laboratory (NSTL) under DRDO, the EHWT project has seen extensive trials to validate its performance under diverse conditions. The initial trials have been conducted using Sindhughosh-class submarines, showcasing the torpedo’s compatibility with existing naval assets. These trials not only test the torpedo’s technical specifications but also its integration into the combat systems of Indian submarines, ensuring seamless operation during live engagements.
The integration of EHWT into the Kalvari-class submarines, which are part of India’s Project-75 Scorpene submarine program, involves collaboration with Naval Group, France, indicating a blend of international expertise with indigenous innovation. This partnership not only ensures the torpedo’s integration but also fosters technological exchange that could benefit future naval projects.
