New Delhi: The Indian Navy is reportedly exploring the concept of a long-range, air-launched, rocket-assisted torpedo system designed to strengthen its anti-submarine warfare (ASW) capabilities in the Indian Ocean Region (IOR), amid concerns over the expanding presence of Chinese submarines in the region.
The proposed system could potentially be launched from manned fighter aircraft and unmanned aerial vehicles (UAVs), allowing the Navy to engage hostile submarines from greater distances while reducing the exposure of aircraft to enemy air-defence systems.
According to preliminary conceptual descriptions, the weapon would combine a conventional lightweight torpedo with a propulsion and range-extension kit. After launch, the propulsion unit would carry the weapon towards the designated target area. The flight kit would then separate, allowing the torpedo to enter the water and search for submarines using its onboard guidance system.
Conceptual estimates suggest a potential stand-off range of 150 to 250 kilometres. However, these figures have not been confirmed by the Indian Navy, and the system remains at the conceptual stage.
Addressing Emerging Underwater Threats
The reported initiative reflects the growing importance of long-range anti-submarine warfare as naval activity increases across the Indian Ocean. The expanding operational presence of the Chinese People’s Liberation Army Navy (PLAN) has heightened the strategic importance of monitoring underwater movements and protecting critical maritime routes.
The Indian Navy currently relies on platforms such as the Boeing P-8I Poseidon maritime patrol aircraft for long-range surveillance, reconnaissance and submarine detection. Conventional air-dropped torpedoes generally require aircraft to approach the target area more closely before releasing their weapons.
A stand-off delivery system could enable aircraft to launch torpedoes from safer distances, potentially reducing their exposure to hostile air-defence networks while expanding operational flexibility.
SMART Programme Offers a Technological Reference
The proposed concept draws comparisons with the Supersonic Missile Assisted Release of Torpedo (SMART) programme developed by the Defence Research and Development Organisation (DRDO).
SMART is designed to deliver a torpedo over long distances using a missile-based delivery mechanism. Unlike the reported air-launched concept, SMART is a surface-launched system intended to extend the reach of naval anti-submarine weapons.
An air-launched variant could offer additional flexibility by allowing aircraft and potentially UAVs to deploy torpedoes across a wider operational area. However, adapting such technology for different launch platforms would involve significant engineering and integration challenges.
International navies are also pursuing stand-off anti-submarine weapons to address the challenges posed by increasingly capable submarines and contested maritime environments.
Development Status Remains Unconfirmed
The proposed air-launched torpedo system has not been officially confirmed by the Indian Navy as a formal procurement or development programme. No final design, confirmed performance specifications or production timeline has been announced.
Moving from a conceptual proposal to an operational weapon would require extensive research, prototype development, testing and integration with aircraft and unmanned platforms. Additional trials would be necessary to validate range, underwater guidance, target acquisition and operational reliability.
If pursued successfully, the concept could eventually provide the Indian Navy with another option for extending its anti-submarine engagement range. For now, however, its status remains exploratory, with its future dependent on technical feasibility, development priorities and official decisions.
