Bharat Dynamics (BDL) delivered a production-grade Wire Guided Heavy Weight Torpedo to the Naval Science and Technological Laboratory (NSTL) at its Visakhapatnam unit on 23 April 2026. The delivery marks a major milestone in indigenous defence manufacturing by the defence public sector undertaking under the Ministry of Defence. Distinguished Scientist and Director General (NS&M) Dr R. V. Hara Prasad, Commodore A. Madhavarao (Retd.), Chairman and Managing Director of BDL, Dr Abraham Varughese, Director NSTL, and teams from BDL, NSTL and the Indian Navy attended the event. BDL has acted as the development-cum-production partner with NSTL to realise India’s first indigenous production-grade Wire Guided Heavy Weight Torpedo in both practice and combat configurations. The programme has been framed as part of the Government of India’s Aatmanirbhar Bharat initiative to strengthen self-reliance in advanced naval weapon systems. The achievement reflects sustained collaboration between DRDO, BDL and a network of industrial partners, including micro, small and medium enterprises. The torpedo incorporates a technology suite that features state-of-the-art homing and propulsion systems along with sophisticated search, attack and re-attack capabilities, which are intended to enhance Indian Navy operational effectiveness. Productionisation of a complex underwater weapon system is presented as evidence of growing indigenous expertise in cutting-edge naval technologies. The project has combined research, testing and industrial production processes to transition from development to production-grade output. Officials at the ceremony acknowledged the dedicated efforts of scientists, engineers and production teams who contributed to the programme. The delivery to NSTL is expected to support further trials, evaluation and eventual induction into service as per user requirements. The milestone underlines BDL’s role in building a robust indigenous defence ecosystem and advances national capability in naval armaments.
