Defence Research and Development Organisation (DRDO) and the Indian Navy successfully conducted the first ever salvo launch of the Naval Anti-Ship Missile Short Range (NASM-SR) today, April 29, 2026. The test took place at the Integrated Test Range in Chandipur, off the coast of Odisha. This mission marked a critical evolution in India’s tactical naval warfare capabilities. Unlike previous single launch trials, this test involved firing two missiles in quick succession from a single naval helicopter platform. This capability is vital for modern naval combat, as it allows for saturation attacks designed to overwhelm the Close In Weapon Systems (CIWS) of enemy warships.
Technical Profile of the NASM-SR
The NASM-SR is India’s first indigenously developed air-launched anti-ship cruise missile. It is a compact but lethal projectile weighing approximately 385 kilograms with a length of about 3.5 meters. The missile is powered by a solid propulsion booster for the initial launch phase, followed by a long burn sustainer motor that maintains its cruise velocity. It travels at high subsonic speeds, roughly 0.8 Mach, which balances fuel efficiency with the ability to close the distance to a target rapidly.
One of the most impressive technical features of the NASM-SR is its launch flexibility. It can be deployed from a maximum altitude of 3 kilometers and is engineered to perform sea skimming maneuvers. During the terminal phase of its flight, the missile drops to an altitude of just 5 meters above the water line. This extremely low flight path makes it incredibly difficult for enemy radar systems to detect the missile against the background clutter of the sea surface. Consequently, the target vessel has very little time to react before impact.
Seeker Technology and Guidance Systems
The guidance suite of the NASM-SR represents a leap in indigenous avionics. For mid course navigation, the missile utilizes a Fiber Optic Gyroscope (FOG) based Inertial Navigation System (INS) coupled with a dedicated radio altimeter. This ensures the missile stays on its intended path and maintains its precise sea skimming altitude without external signals.
However, the centerpiece of its lethality is the Imaging Infrared (IIR) seeker. Unlike older missiles that use active radar homing, which can be detected and jammed by electronic warfare suites, the IIR seeker is entirely passive. It “sees” the thermal signature of the target ship. This makes the NASM-SR virtually immune to conventional radar jamming and decoys like chaff. Furthermore, the missile features a high bandwidth two way data link. This allows the pilot in the helicopter to receive live images from the missile’s seeker during flight. The pilot can then perform in-flight retargeting, selecting a specific vulnerable spot on the ship, such as the bridge or the engine room, even after the missile has been launched.
The Importance of the Salvo Launch and Waterline Hits
Today’s test was specifically focused on validating the salvo launch logic. In a real world combat scenario, firing a single missile might allow a modern destroyer to intercept the threat using its rapid fire cannons or short range missiles. By launching a salvo, the Indian Navy can present multiple threats simultaneously from different angles. The test data confirmed that both missiles followed their designated trajectories perfectly and hit the target at the waterline.
A waterline hit is the gold standard for anti-ship strikes. By striking a vessel where the hull meets the water, the missile causes immediate and severe flooding. The 100 kilogram high explosive warhead is optimized to create a massive breach in the ship’s buoyancy, which is far more effective at sinking a vessel than hitting the superstructure. The successful demonstration of this accuracy today proves that the NASM-SR can punch well above its weight class.
Developmental History and Platform Integration
The NASM-SR project was first officially revealed to the public around 2018. It was designed specifically to replace the aging British built Sea Eagle missiles that have served the Indian Navy for decades. The maiden flight test occurred on May 18, 2022, which validated the basic aerodynamic and propulsion parameters. Since then, the DRDO has conducted several trials to refine the seeker algorithms and the data link performance.
Initially, the missile was integrated with the Sea King 42B helicopters. However, with the Sea King fleet nearing retirement, the primary focus has shifted to the MH-60R Romeo multi role helicopters recently acquired from the United States. Today’s salvo launch confirmed that the indigenous launcher and the fire control system are fully compatible with modern naval helicopter platforms. There are also discussions about integrating the NASM-SR with the upcoming Indian Multi Role Helicopter (IMRH), which would further unify the Navy’s tactical strike capabilities.
Strategic Impact and Future Roadmap
The successful salvo test of the NASM-SR is a major victory for the Atmanirbhar Bharat initiative in the defense sector. By developing its own short range anti-ship missiles, India is no longer dependent on foreign suppliers for its tactical maritime defense. This provides the Indian Navy with operational freedom and ensures that its strike platforms remain lethal even if international supply chains are disrupted.
Looking forward, the NASM-SR is expected to be the first in a family of indigenous naval missiles. The DRDO is already working on a Medium Range (MR-AShM) and Long Range (LR-AShM) version. These future iterations will likely feature larger warheads and range capabilities exceeding 150 to 250 kilometers. Today’s milestone off the Odisha coast has laid the technical foundation for these future projects. As the Indian Navy continues to modernize, the NASM-SR will stand as a testament to the nation’s growing capability to secure its vast maritime borders with high tech indigenous solutions.
