For the first time, the Defence Research and Development Organisation (DRDO) has revealed the specifications of its newly developed Heavyweight Torpedo (HWT), showcasing a scale model of the torpedo at Aero India 2025. This advanced torpedo is being developed in collaboration with the Naval Group and is expected to be integrated into India’s Kalvari-class submarines as part of a recent deal between the two entities.
The Heavyweight Torpedo (HWT) is a state-of-the-art weapon designed to enhance the operational capabilities of the Indian Navy’s submarine fleet. With its remarkable range, speed, and endurance, the torpedo promises to strengthen the Indian Navy’s anti-submarine and anti-surface warfare abilities.
The 50 km range and 50 knots speed make the HWT a formidable weapon capable of striking both surface and submerged targets. Its endurance of 3000 seconds ensures that the torpedo can maintain its course for extended periods, making it highly suitable for long-duration naval operations.
With a depth of operation of up to 600 meters, the HWT can be used in a wide range of underwater combat scenarios, targeting both surface vessels and other submarines. The torpedo’s wire-guided system allows for precise control and targeting, ensuring that it remains on course to strike high-value targets deep in the ocean.
The dimensions of the torpedo – measuring 6 meters in length and 533.4 mm in diameter – are ideal for fitting into the torpedo tubes of modern submarines, specifically designed for the Kalvari-class submarines of the Indian Navy. At a weight of 1630 kg, the HWT is large enough to carry a significant payload, providing the Indian Navy with a potent long-range weapon for anti-submarine and anti-surface operations.
One of the key milestones in the development of the HWT is its integration into India’s Kalvari-class submarines. The Indian Navy has recently reached a deal with DRDO and the Naval Group to begin integrating the torpedoes into the fleet. This will enhance the Kalvari-class submarines’ strike capabilities, as they will now be armed with advanced, long-range torpedoes designed to target both enemy ships and submarines with exceptional precision.
The DRDO’s HWT is built to meet the requirements of modern naval warfare, offering a variety of features that make it an effective and reliable weapon. Here are the key specifications:
- Range: 50 km
- Endurance: 3000 seconds (approximately 50 minutes)
- Speed: 50 knots
- Operating Depth: 600 meters
- Dimensions:
- Length: 6000 mm (6 meters)
- Diameter: 533.4 mm
