The Defence Research and Development Organisation (DRDO) and the Indian Navy successfully conducted the maiden salvo launch of the indigenous Naval Anti-Ship Missile Short Range (NASM-SR) on April 29, 2026. The test, carried out off the Odisha coast in the Bay of Bengal, involved launching two missiles in quick succession from a Navy helicopter. This milestone achievement demonstrates India’s growing capability in developing advanced air-launched precision-strike systems for maritime security.
Maiden Salvo Launch: Enhancing Maritime Strike Power
The trial conducted off the coast of Odisha marked a significant breakthrough as it was the first time India demonstrated a salvo launch capability for an air-launched anti-ship missile. In a salvo launch, multiple missiles are fired in rapid succession or simultaneously to overwhelm the target’s defensive systems, such as Point Defence Missile Systems (PDMS) or close-in weapon systems. The Indian Navy used a Sea King helicopter for the launch, confirming the system’s compatibility with existing naval aviation platforms.
During the mission, the missiles followed a precise flight path and achieved what naval experts call a waterline hit. This means the missiles struck the target vessel at the level where the hull meets the water, which is the most vulnerable part of a ship. Such a strike is designed to cause maximum damage, leading to rapid flooding and potentially sinking the vessel. The successful execution of this complex mission validates the tactical readiness of the NASM-SR for high-intensity maritime operations.
Technical Specifications and Indigenous Technology
The NASM-SR is a high-technology weapon system designed to be carried by various naval helicopters. It weighs approximately 400 kg and is equipped with a 100 kg warhead, making it a potent tool against small to medium-sized surface vessels. The missile has a length of 3.6 metres and a diameter of 300 mm. With a strike range of 55 km, it allows naval helicopters to engage enemy ships from a safe distance, well outside the range of most ship-borne anti-aircraft guns.
The missile is powered by a solid propellant rocket motor and can achieve speeds of up to Mach 0.8 (high subsonic). One of its most advanced features is the indigenous Imaging Infra-Red (IIR) seeker, which provides high-resolution images for precise target identification and tracking, even in adverse weather conditions. The system also includes a high-bandwidth two-way data link, enabling “man-in-the-loop” control for in-flight course corrections or retargeting if necessary. It is designed to operate at altitudes ranging from 50 metres to 3 km, allowing for sea-skimming trajectories that make it difficult for enemy radars to detect.
Strategic Importance and the Push for Atmanirbhar Bharat
The successful salvo launch of the NASM-SR is a major step towards achieving self-reliance in naval missile technology under the Atmanirbhar Bharat initiative. For decades, the Indian Navy has relied on foreign-origin anti-ship missiles, such as the British-made Sea Eagle. The indigenous development of the NASM-SR ensures that the Navy has a reliable, state-of-the-art strike capability that is free from the risks of supply chain disruptions or export restrictions.
This development also strengthens India’s maritime security posture in the Indian Ocean Region (IOR). By equipping naval helicopters with long-range, precision-strike missiles, the Navy can effectively monitor and protect India’s vast coastline and Exclusive Economic Zone (EEZ). The ability to launch missiles in a salvo format provides a decisive tactical advantage in naval warfare, as it significantly increases the probability of neutralizing high-value targets while minimizing the risk to the launch platform.
Development Agencies and Collaborative Effort
The NASM-SR is the result of a collaborative effort led by the Research Centre Imarat (RCI), a premier laboratory of the DRDO located in Hyderabad. RCI was established in 1988 and has been the lead agency for the development of missile systems, including the Agni and Prithvi series. Other DRDO laboratories, including the Defence Research and Development Laboratory (DRDL) and the High Energy Materials Research Laboratory (HEMRL), contributed critical components like propulsion systems and warheads.
The Indian Navy provided essential operational support and testing platforms throughout the development phase. The project also involved several private sector industries, showcasing the strength of India’s defence industrial base. The Defence Research and Development Organisation (DRDO), which operates under the Ministry of Defence, was established in 1958 and is headquartered in New Delhi. Its primary mission is to design and develop world-class weapon systems and equipment for the Indian Armed Forces.
